How Do You Grind Metal with a Drill Bit?

So, let’s see how a metal grinding drill bit works.

Take a sharp drill bit. More precisely, take a Syndent grinding bit.

Fix it well in the collet of your specific rotary machine.

Place your metal work piece on the table and ensure it is screwed properly to the bench.

Check the connections of your machine, whether it is an electric switch or an air hose. And if, you are using a cordless drill, make sure the battery is fully charged.

Now start the machine. Take a slow start. Put the rotating carbide burr on the surface of your metal piece.

As soon as the sharp flute teeth touch the surface, they chip out the metal chunks. The bit keeps rotating and chipping out excessive metal.

You don’t need to press the bit against the surface because Syndent metal grinding drill bits are sharp enough to cut the metal like butter.

Keep moving the rotating burr until the whole surface is ground.


  • The unnecessary force put on the rotary file may damage the flute’s sharpness.
  • Speed is vital while grinding. You must start at a slow pace but increase the speed gradually as you move along. Moreover, keep working within the recommended speed limit.
  • Most importantly, the flute cut, you choose, plays a vital role. Syndent offers a wide range of flute cuts like:

Flute Cuts for Rapid Stock Removal

  • Aluminum cut
  • Single cut
  • Coarse cut
  • Foundry cut

What Are Numerous Metal Grinding Drill Attachments?

Variable tools are available in the market to grind metal. The tools that you can use as an attachment with a drill machine are:

  • Grinding wheels
  • Metal grinding drill bits

Grinding Wheels

Grinding wheels have hole in the middle. You can use a mandrel to connect wheel to the collet. This mandrel is called a drill arbor adapter.

The mandrel is attached to the grinding wheel with a screw.

Tightly fix the screw. Now your wheel is ready to mount on the drill machine. Fix it in the drill chunk and start grinding.

Variable-sized grinding wheels are available in the market. Mostly, they are used to grind larger areas.

Metal Grinding Drill Bits

Drill bits are an ideal solution to grind corners, small, and narrows areas. You can get them in variable shapes and sizes.

You can easily fix the shank into the drill collet to grind metal.

Generally, grinding drill bits are of three types:

As the names suggest, different materials are used to make these metal grinding drill bits. Let’s see what the differences are.

What Is the Difference between a Metal Grinding Carbide Burr and Stone Drill Bit?

Both of these metal grinding drill bits are designed explicitly to smoothen a rough metal surface. Moreover, the two types are available in a wide variety.

However, they differ in many ways, like:

The difference in Raw Material

To manufacture metal grinding drill bits, tungsten carbide is used. Likewise, chemical compounds are used to create strong stone burrs.

Abrasives (like aluminum oxide) are used to create stone bits. After that, high-grade bonds are used to keep the abrasive grits strongly intact.

Stone Grinding Drill Bit

Stone Drill Bits

Cuts & Grits

In tungsten carbide metal grinding drill bits, the flutes have sharp cuts. These cuts are available in various patterns. Coarse and fine cuts determine the grinding results.

On the contrary, stone (aluminum oxide) files do not have cuts. In fact, they have grits on the flutes. Coarse, medium and fine grits help in aggressive and fine finishing.

Life Span

Metal grinding drill bits (carbide bits) have a longer life span than stone bits. The sharp flutes retain their shape and sharpness even after aggressive grinding.

However, you may observe detrition in the stone burrs after excessive grinding.

What Is the Difference between a Grinding Wheel and Metal Grinding Drill Bit?

As mentioned earlier, wheels and bits are available as drill attachments. If, wheels can fulfil the grinding job, then what is the need to have metal grinding drill bits?

Let’s explore:

Shape & Sizes

The minimum diameter of a grinding wheel is 4.5”. It means, to grind spaces smaller than 4”, you need to have some other tools.

For this purpose, metal grinding drill bits are the best. Whether you are using an abrasive drill bit or carbide drill bit, you can conveniently grind hard-to-reach areas.

You can conveniently work on diversified areas with these multipurpose drill bits.

On the contrary, grinding wheels are more suitable for flat surfaces.

Abrasive Grinding Wheel

Abrasive Grinding Wheel

Raw Material

Grinding wheels are created with abrasives. Different types of chemical compounds are mixed with abrasive bonding to form grinding wheels.

The abrasive size and volume on the wheel differ. Some wheels have coarse while others have fine grits.

Coarse grits remove stock faster with less finished surface. Whereas, fine grits remove finer chunks, thus, leaving the surface smoother.

Besides the difference in size, abrasive metal grinding drill bits possess the same features. However, carbide drilling bits are made with the world’s strongest metal cobalt – tungsten carbide.


Can I Use a Metal Grinding Drill Bit to Cut Through Metal?

Syndent metal grinding drill bits are well-known for grinding, deburring, sanding, and polishing purposes.

Drill bits are not made to cut metal. Furthermore, cutting a metal sheet is not a piece of cake.

However, Syndent sharp, durable, and resilient metal grinding drill bits may cut various metals for you.

Metal Grinding Drill Bit


You can use burrs having aluminum cut, single cut, or coarse cut flutes. These flutes quickly remove heavy stock and help in the aggressive cutting.
