Carbide burrs are tools employed for deburring most hard materials like ceramics, stone, steel, aluminum, plastics and hardwood. They provide precision, which enable it to also be used in cutting, shaping, grinding and chamfering hard materials.
Carbide burrs may be used with a various materials for example metals (including Steel aluminum and cast iron) and all kinds of wood. You can use it on acrylics, fiberglass and plastics too. Carbide burrs can last for quite a long time without chipping or breaking to ensure it’s so excellent to utilize them on soft metals like gold,platinum and silver.
What Are The Aspects of Carbide Burrs In comparison with HSS Burrs?
In comparison with HSS, Carbide Burrs are much harder.
The Tungsten Carbide is quite hard to enable them to be utilized in wider array of work than HSS (Very fast Steel).
HSS can’t perform as well as carbide burrs if they’re at temperature. Carbide Burrs can bear hotness which enable it to run longer time.
Carbide won’t soften at high temperature but HSS burrs is opposite. No doubt that carbide is the perfect choice.
How to Use Carbide Burs:
For more stability, insert the accessory bit in to the unit and then back against each other slightly before tightening along the collet nut or keyless chuck.
Avoid the use of these for drilling holes or enlarging holes that are under twice the diameter from the cutter. The tungsten carbide surface can readily catch along side it of a hole and break the part.
Use higher speeds for hardwoods, slower speeds for metals and slow speeds for plastics (to stop melting at contact point).
Start in a lower speed. Then increase to the speed that gives probably the most favourable results.
Don’t apply excessive pressure. It could decrease the spindle and chip cutting edges. Let the bur perform the cutting.
Utilize sides in the cutter for effective cutting. The tip cuts poorly and may break being forced.
Never in-capsulate the bur from the cut. If chattering occurs, increase speed.
When you use aluminium and magnesium, consider some form of lubricant, wax or tallow, since it will help steer clear of the flutes from loading or packing.
Carbide burs, if used the proper way, will outperform HSS burs by 50
