Extended Length Carbide Burrs – Ultimate FAQ Guide

Are you looking for carbide burrs with extra-large shaft sizes?

Syndent is one of the leading manufacturers and suppliers of extended length carbide burrs. With the help of these rotary files, you can grind and deburr long and narrow spaces conveniently.

Let’s move further to know about the types, specifications, and manufacturing process of Syndent extended length carbide burrs.

What Are Extended Length Carbide Burrs?

Syndent manufactures long length carbide burrs to work on spaces that regular burrs cannot reach. These burrs have long shanks.

The shank sizes range from 3 inches (75mm) to 12 inches (300mm). However, the most commonly used size is 6 inches (150mm).

As the length of the shank increases, the burr tends to jump more while machining. But Syndent make a better control on the balance.

Anyhow, Syndent recommends you to work at a slower speed while working with your extended length carbide burrs.

It is also known as long-reach carbide burrs. It is suitable for grinding, deburring, cutting, and milling in difficult areas to reach.

You can use extended length carbide burrs on variable surfaces and with multiple tools. Syndent manufactures long shank burrs with various shapes and cuts.

For your convenience, you can get customized shapes and sizes of your carbide burrs. Syndent’s high-grade tungsten carbide burrs help you attain the best results in whichever industry you work in.

What Is the Manufacturing Process of Extended Length Carbide Burrs?

Syndent manufactures extended length carbide burrs with the best raw material. The quality control team inspects every step of the procedure.

Highly efficient and advanced machines are used to provide you durable carbide burrs. Here are the steps Syndent follows to make the best rotary tools for you.

Raw Material Gathering

Syndent gathers the cobalt–tungsten carbide from state-owned suppliers. The QA/QC team then inspects the high-grade tungsten carbide.

After the approval, the material is then sent to the factory to start the manufacturing process. Syndent uses tungsten carbide for making extended length carbide burrs because of its robust nature.

Tungsten carbide burrs can work on variable surfaces, including hard steel and rock.

Silver Brazing

The raw flute and shank are joined together by the brazing technique. Brazing means that the base material (shank and flute) is not melted.

A filler material is used, melted, and filled to join both metal parts. Syndent uses silver as the filler material.

Silver is melted and brazed at a very low temperature.

Balancing Test

After joining both parts and before attaining the final shape, Syndent performs a balancing test on each extended length carbide burrs.

Long shanks tend to jump more and need a solid balance to work smoothly. Syndent ensures that the tolerance level does not exceed 0.1mm.

Bending Test

After checking the balance of the extended length carbide burrs, Syndent conducts another test that is the bending test. Brittle burrs tend to break as soon as you start working on a hard surface.

To avoid such conditions, Syndent makes tungsten carbide burrs ductile and durable. The burrs are bent to a specific level to check the flexibility and resilience.

The bending test ensures that you can conveniently work on more challenging surfaces without the fear of damage or breakage.

Shaping & Toothing

After testing the balance and durability, the burrs get their shape. Precise grinding takes place to give the carbide burrs their predetermined shape.

The CNC machines grind the extended length carbide burrs and create sharp flutes. The QA/QC team ensures that the flutes have sharp and uniform teeth to provide you smooth and finished results.

Polishing

To give the extended length carbide burrs a finished and smooth finish, Syndent polishes the shanks, flutes, and brazing points precisely.

Packaging

In the end, the finished burrs are packed in exceptional cases. Syndent’s logos on the burrs and casing are a sign of high quality and durability.

You can get your company’s customized logos and name on the burrs and casing on demand.

What Are the Uses of Extended Length Carbide Burrs?

Extended length carbide burrs are specifically designed to reach long and narrow spaces. You can utilize these burrs for multiple functions. Like:

Deburring

Deburring means, remove unwanted material from a surface. To remove undesired metal chunks from a long and narrow surface, extended length carbide burrs are an ideal solution.

Shaping

Rotary burrs are suitable to shape a de-shaped metal piece. You can conveniently use carbide burrs to shape ferrous and non-ferrous materials.

Grinding

Grinding a narrow has never been so easy. Syndent’s extended length carbide burrs provide you a smooth grinding experience.

The sharp flute teeth and high rotatory speed help you to perform the grinding quickly and effectively.

Hard steel, ferrous, and non-ferrous materials are easy to grind without the fear of breakage or getting hot.

Cutting

With the sharp flutes of your extended length carbide burrs, you can conveniently cut any surface into small pieces.

The primary purpose of carbide burrs is to grind or deburr. However, you can cut a surface with your rotary files.

You may not get accurate results as a cutting wheel may provide you, but you can smoothen the edges later on by grinding.

Enlarging Holes

Drilling is another function Syndent’s carbide burrs can perform significantly. Digging into any material, making holes, or enlarging holes is an easy task to do with your extended length carbide burrs.

The extended shank length allows you to dig in farther than a regular shank can do for you. You can attain variable shapes by digging in a material, like make curved corners, work on pointed holes, or arced holes.

How?

It leads to our next question. Let’s read further.

What Are the Various Types of Extended Length Carbide Burrs?

Syndent manufactures extended length carbide burrs in variable sizes and shapes. These shapes allow you to work on various surfaces.

For example, to grind a right-angled corner, have a cylindrical burr with end cut, or work on curved or round edges, you may use a ball-shaped burr.

Let’s find out more about the various shapes and their uses.

Cylinder Shape Extended Length Carbide Burrs

It is an ideal burr to remove unwanted metal chunks from a flat surface. Cylindrical burrs are available with

• End cut
• Radius end
• Flat end

These ends facilitate you to work on multiple surfaces. For example, a cylindrical burr with an end cut can work on a right-angled corner of a flat surface.

Cylinder shape rotary file with a radius end is suitable to work on a flat surface with a round or arced angle corner.

Ball and Oval Shaped Extended Length Carbide Burrs

Machining around curved edges is possible with the help of a ball-shaped or oval-shaped carbide burr.

Giving a smooth finish without destroying the round corners can conveniently be done with the help of these burrs.

These two shapes are ideally used before brazing. The fast-moving round burr gives the surface a smooth finish which you can conveniently treat with a filler material later on.

Tree Shaped Extended Length Carbide Burrs

Long shanks are helpful to reach long and narrow spaces. Tree-shaped burrs are also known for their easy-to-reach property in challenging positions.

There are two types of tree-shaped burrs – pointed end and radius end. Pointed end burrs are suitable for grinding round edges on the corners.

At the same time, radius end files are helpful to contour corners with arc and curves.

Various Shapes

Some other valuable shapes Syndent manufactures to suit your need are:

• Cone shape
• Taper shape with a pointed end
• Taper shape with radius end
• Flame shape burr
• Inverted cone shape carbide burr

In Which Tools Can I Use Extended Length Carbide Burrs?

Syndent’s extended length carbide burrs work at a very high speed. Die grinders are the best partner to work along with the high-speed rotary tools.

However, Syndent makes the shank head diameter of a standard size that suits most rotary tools.

Apart from die grinders, the rotary burrs can also effectively work with pneumatic rotary tools, pendant drills, hobby drills, high-speed engravers, and micromotors.

No matter which tools you choose for machining, the most important thing is that you fix your extended length carbide burrs firmly into the collet.

Loose and badly fixed burrs can result in serious injury.

What Is the Importance of Extended Length Carbide Burrs in Sculpture Making?

Sculpture making is a profession as well as a hobby for many. Sculptures are made on various materials like wood, stone, metal, plaster, clay, and many more.

Sometimes sculpting becomes difficult with chisel and hammer. Syndent has made it convenient for artists to create sculptures on hard surfaces.

If you are an artist, you can conveniently carve a wood log into a fine portrait. Variable burrs make it easy for you to chip out the desired piece.

Radius ends, pointed ends, and flat ends make it easy for you to create a required shape on your sculpture.

Syndent’s extended length carbide burrs are an added advantage to your tool kit. It can reach areas that a standard burr cannot grind.

You can reach a deep hole or make a deep cut with the help of a long shank burr. The handy small-sized rotary tools are easy to carry. A sculptor can conveniently have the rotary tool and grind the desired area.

At the same time, the fats moving burrs allow you to complete the sculpture in less time than chipping out with a chisel and hammer.

So, a sculptor can precisely understand the importance of fast-moving rotary tools. They are creating a difference in the field of sculpture making.

Does High Pressure Accelerate the Milling Process?

Pressure is not the primary factor to grind or deburr. Sharp flute teeth are explicitly designed to give you the desired results without putting pressure.

Especially when it comes to extended length carbide burrs, you do not need to put more pressure. Unnecessary pressure will cause your burr to jump and wobble.

Wobbling may end up in uneven lines and unwanted results. Unwanted pressure can also damage your carbide burr.

A gentle force with firm gripping is all you need to attain the desired results. It is recommended to start your work at a slow speed.

Switch on the die grinder first and then put it on the workpiece. Slowly increase the pace of your die grinder and keep moving the rotating burr.

Forced pressure can result in blunt edges of your carbide burrs, and very slow speed can result in clogged flute teeth.

What Preventions Must Be Taken While Working with the Extended Length Carbide Burrs?

You must always take precautionary measures while working with your extended length carbide burrs. Your safety is our priority. That is why Syndent provides you manual guide with your carbide burrs.

The precautions are:

• While changing or screwing the burr into the collet, ensure that the power supply is not intact.
• The air pressure of your air hose must not exceed 90psi.
• Ensure that your air hose is away from heat or any flammable object.
• Don’t put any sharp object near the air hose and keep the area clean from oil.
• Ensure that every connection is secured.
• Wear ear defenders, goggles, gloves, face shield, and breathing protection (if needed).
• Wear proper boots and clean the area from any slippery material like water or oil.
• Your workpiece and burr in the collet must be tightly clamped.
• It is recommended that you start your rotary tool first and then put the burr on the workpiece.
• While working with extended length carbide burrs, you must begin with a slow speed. Gradually increase the speed as you hold on to the tool correctly (speed guide is provided with your carbide burrs).
• 
• The sharp flute of your burr is enough to attain the desired grinding results. You do not need to put excessive strain on the burr to get the results earlier.
• Avoid working at a very slow pace. It will end up in flute clogging.
• Immediately after grinding, do not touch the burr or the workpiece. With friction, both metals must be very hot.
• Your clothes must be fire-retardant.
• Your workshop or working area must be free from any flammable object.
• After use, unplug your rotary tool.
• Clean the burr after every use and keep it in a safe and dry place.

In How Many Cuts Are Extended Length Carbide Burrs Available?

Syndent manufactures many standard and unique cuts of the extended length carbide burrs. These cuts are helpful in various applications.

The three standard cuts are:

Single cut

These burrs have a single spiral cut running upwards on the flute. These burrs are ideal for removing larger chips and attaining the grinding results faster.

You can conveniently use single-cut carbide burrs on copper, cast iron, stone, hardened steel, and hardwood.

To remove extra material aggressively from rigid materials, these burrs are an ideal solution. You can use single-cut carbide burrs for cleaning, milling, deburring, and eliminating heavy stock.

Double cut

Double-cut carbide burrs are ideal for removing more minor chips from hard materials. Small chip removal results in a smoother finish and quick results.

Syndent’s double-cut carbide burrs are ideal to be used on ferrous and non-ferrous materials. You can use double-cut carbide bits for cleaning, polishing, deburring, grinding, smooth finishing, and removing more minor chips.

Aluminum cut

Syndent’s aluminum-cut carbide burrs are specifically designed to work on aluminum. You can also use them on non-ferrous metals and non-metallic materials.

These burrs remove heavy stock quickly and are ideal for deburring and polishing.

Besides the three standard cuts, Syndent manufactures some special cut extended length carbide burrs. These burrs are ideal for working on specific metals and materials.

The various special cuts are:

• Coarse cut
• Fine single cut
• Foundry cut
• Diamond cut
• Chipbreaker cut
• Fast mill cut
• 

Is There a Special Way to Use Extended Length Carbide Burrs?

There are specific techniques you must follow while working with your extended length carbide burrs. By following these techniques, you can attain the best results.

These are:

• A moderate pressure gives you better results and a firm grip.
• Unnecessary stress may cause damage burr and uneven lines on the workpiece.
• Extended length carbide burrs tend to jump more with very high speed or excessive pressure.
• Working at a low rate can result in metal clogging on the flute.
• It is safe to start your rotary tool before putting the burr on the workpiece.
• Keep the burr moving. Grinding at one place for an extended time may result in uneven lines.
• Ensure that the burr in the collet and workpiece on the bench are tightly screwed.
• Try to move along the rotation of your burr to get better results.
• It is better to end in an ‘up’ stroke to get a smooth finish.
• Always choose a smaller in diameter bit than the working space. For example, if the hole size is 1 inch, Syndent recommends you to work with a half-inch or smaller in diameter burr.

How Can I Clean My Extended Length Carbide Burrs?

Metal clogging is a common problem to observe while working with your extended length carbide burrs.

It is not a big deal. You can conveniently remove the clogged metal from your burr by using the following methods.

If your burr has aluminum chunks clogged on the flute, firstly, try to chip out as much material with a stiff brush as possible.

After that, dip the burr in muriatic acid (HCL) for a while. Let the acid do its part. The acid will dissolve the aluminum leaving your burr neat and clean.

Ensure that you dip only the flute into the acid. Dropping the shank may cause damage to the burr.

The second way to clean your burr is to use ultrasonic waves. It is recommended to use if the flute is clogged with steel or material like that.

Run the carbide burr for about 2 minutes in an enzymatic cleaner. After that, rinse the burr with cold water.
