Carbide burrs are tools useful for deburring most hard materials like ceramics, stone, steel, aluminum, plastics and hardwood. They offer precision, which enable it to also be employed in cutting, shaping, grinding and chamfering hard materials.
Carbide burrs may be used on a variety of materials including metals (including Steel aluminum and cast iron) and all kinds of wood. It can be used on acrylics, fiberglass and plastics too. Carbide burrs may last for quite a long time without chipping or breaking to ensure it’s so good to use them on soft metals like gold,platinum and silver.
What are Advantages of Carbide Burrs Weighed against HSS Burrs?
Weighed against HSS, Carbide Burrs are much harder.
The Tungsten Carbide is extremely hard so that they can supply in wider range of work than HSS (Broadband Steel).
HSS can’t be as good as carbide burrs if they’re at high temperature. Carbide Burrs can bear hotness and may run longer time.
Carbide won’t soften at hot temperature but HSS burrs is opposite. No doubt that carbide is a better choice.
How to Use Carbide Burs:
For additional stability, insert the accessory bit in the oral appliance then back out slightly before tightening down the collet nut or keyless chuck.
Do not use these for drilling holes or enlarging holes which might be less than twice the diameter from the cutter. The tungsten carbide surface can certainly catch the medial side of an hole and break the bit.
Use higher speeds for hardwoods, slower speeds for metals and slow speeds for plastics (to prevent melting at contact point).
Start in a lower speed. Then increase towards the speed that provides one of the most favourable results.
Don’t apply excessive pressure. It could slow down the spindle and chip cutting edges. Let the bur do the cutting.
Utilize the sides in the cutter for effective cutting. The top cuts poorly and can break under time limits.
Never in-capsulate the bur from the cut. If chattering occurs, increase speed.
When using aluminium and magnesium, consider some type of lubricant, wax or tallow, because it can help steer clear of the flutes from loading or packing.
Carbide burs, if used the correct way, will outperform HSS burs by 50
