Burr Bit – The Complete FAQ Guide

Syndent welcomes you to the ultimate FAQ guide page of tungsten carbide burr bits. In this article, you will find types, usage, advantages, and applications of high-grade burring bits.

In case, you have some other queries that are not explained here you can contact Syndent for more details.

Let’s get started!

What Is a Burr Bit?

It is a small yet powerful rotary tool that enables you to perform on multiple surfaces in numerous ways.

Here are two main things:

  • Working on multiple surfaces
  • Working in numerous ways

Multiple surfaces mean, that you can conveniently finish with your burr bits on soft materials and hard metals to attain the desired results.

Whereas, numerous ways include grinding, cutting, deburring, milling, sanding, and preparing a surface for polishing.

Syndent is well-known for manufacturing burring bits from the state’s best tungsten carbide. These solid burbits rotate at a very high speed and give you the desired results in seconds.

Another amazing quality of Syndent burr bits is that they might be fit in multiple rotary tools.

Can I Use a Burr Bit in a Drill?

Die grinders run at a speed between 20,000 and 50,000RPM more. On the other hand, a drill machine works on 200 – 2000RPM.

It is a huge difference!

In newer drill machine models you can switch between 2 – 4 speeds. The difference in speed has a great effect on the grinding results.

Syndent burr bits are not made for drill machines. However, if you don’t have another option, you can put them in hobby drills.

But remember, greater speed provides you with finer results.

What Is a Burr Bit Set?

It is a convenience pack. By purchasing a burbit set, you can get multiple burrbits in a single pack. Syndent’s burr bit sets are available in 12, 10, 9, 8 pieces sets, etc.

Let’s see what is inside these burring bit sets.

Burr Bit Set of 12 Pieces

In this pack, you can get 12 burrs having variable sizes and shapes. It is the most in-demand set and is useful in many applications.

Set Having 10 Burrs

This set contains 10 burbits with double-cut flutes.

9 Pieces Burrbit Set

In this set, you will find 9 miniature burr bits.

Burr bit Set Having 8 Files

This set is a recommended solution when you face metal removal.

5 Pieces Burring Bit Set

This set also contains burrs with double-cut flutes. These are ideal for contouring and getting a surface finish.

Burbit Set Having 4 Bits

The four unique extended length burr bits are gathered in this set. You can quickly remove stock from hard-to-reach areas with the support of these burrbits.

What Is a Carbide Burr Bit Used for?

Let’s see what is the purpose behind creating so many shapes and sizes of a burr bit?

Carbide burr bits are ideal to:

  • Grind
  • Cut
  • Shape
  • Deburr
  • Sand
  • Clean
  • Polish

Let’s see what is the use of various burbit shapes.

Use of Cylinder Shaped Burrbits

Burr bits having cylinder-shaped flutes are very helpful in grinding flat surfaces. They are available in variable end cuts.

Some have a flat end, some have end cuts, or radius end to work on flat spaces with curved or perpendicular corners.

Use of Ball and Oval Shaped Burbits

Ball and oval-shaped burr bots are suitable to contour round edges.

Tree and Flame Shaped Burring Bits

These burrs are created to mill deep and narrow spaces. They are obtainable in pointed or radius ends.

Can I Have Free Shipping on Quality Burr Bits?

Syndent gives you fast and quick shipping services at a very low cost. Syndent’s trusted shipping partners deliver your consignments on a priority basis.

Within 15 – 20 days you may receive your quality burr files.

What Are the Various Factors Affecting the Speed of the Burring Bit?

There are two factors that determine the rotating speed of the burr bits. These are:

  • Burbit size
  • Material of the workpiece

Material of the Workpiece

Speed varies on variable materials. For example, on steel, the speed ranges from 22,500 – 30,000 RPM, on cast iron the rotating speed may vary between 11,000 – 30,000RPM, and on plastic or aluminum the working speed 7,000 – 35,000RPM.

Diameter Size

Similarly, depending on the burr bit size (flute diameter and shank length), the speed may vary.

Flute Diameter

The speed and the size work opposite to each other. It signifies that the greater the flute diameter, the slower the speed will be, and vice versa.

Let’s take the example of a burr bit with a flute having 3mm diameter that equals 1/8”. Its’ ideal rotary speed varies between 17,000 – 26,000RPM.

On the other hand, a burbit of 16mm (5/8”) flute diameter can work on 7,650 – 11,500RPM.

Shank Length

Long-shank die-grinder burr bits run at a comparatively lower speed. The reason is, longer the shank length, the more area will be exposed to the milling vibrations.

In small-sized butbits the shank is tightly gripped in the collet and stays firm and steady while speedy rotations.

On the contrary, in longer shanks, the burring bit starts to vibrate as you increase the speed of the machine.

So, you are recommended to work at a slower speed if you are using a long shank burr bit.

Which Burr Bits Are Suitable for Rapid Stock Removal?

Syndent has the credit of producing numerous burr bits. These burring bits are suitable of different purposes.

If you need a burbit that can remove unwanted material quickly, Syndent offers you the aluminum cut, single cut, coarse cut, fast mill cut, and foundry cut burrbits.
