How To Use Carbide Burs

Carbide burrs are tools useful for deburring most hard materials like ceramics, stone, steel, aluminum, plastics and hardwood. They provide precision, and can double in cutting, shaping, grinding and chamfering hard materials.

Carbide burrs may be used on the various materials for example metals (including Steel aluminum and iron) and all forms of wood. You can use it on acrylics, fiberglass and plastics too. Carbide burrs can last for a long time without chipping or breaking so that it’s so great for their services on soft metals like gold,platinum and silver.

Which are the Aspects of Carbide Burrs Weighed against HSS Burrs?

Compared with HSS, Carbide Burrs tend to be harder.

The Tungsten Carbide is extremely hard so that they can be used in wider variety of work than HSS (Very fast Steel).

HSS can’t perform as well as carbide burrs if they are at temperature. Carbide Burrs can bear hotness and will run for time.

Carbide won’t soften at temperature but HSS burrs is opposite. No doubt that carbide is the perfect choice.

The way you use Carbide Burs:

For further stability, insert the accessory bit to the tool and then back it slightly before tightening on the collet nut or keyless chuck.

Do not use these for drilling holes or enlarging holes which might be lower than twice the diameter in the cutter. The tungsten carbide surface can easily catch the inside of the hole and break the bit.

Use higher speeds for hardwoods, slower speeds for metals and slow speeds for plastics (in order to avoid melting at contact point).

Start with a lower speed. Then increase towards the speed which gives the most favourable results.

Don’t apply excessive pressure. It can slow up the spindle and chip cutting edges. Just let the bur perform the cutting.

Utilize sides of the cutter for effective cutting. The top cuts poorly and can break being forced.

Never in-capsulate the bur from the cut. If chattering occurs, increase speed.

When utilizing aluminium and magnesium, consider some kind of lubricant, wax or tallow, as it can help stop the flutes from loading or packing.

Carbide burs, if used the right way, will outperform HSS burs by 50
