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

Carbide burrs can be utilized with a selection of materials such as metals (including Steel aluminum and iron) and varieties of wood. You can use it on acrylics, fiberglass and plastics too. Carbide burrs may last for quite a while without chipping or breaking in order that it’s so excellent to utilize them on soft metals like gold,platinum and silver.

What are Attributes of Carbide Burrs In comparison with HSS Burrs?

Compared with HSS, Carbide Burrs tend to be harder.

The Tungsten Carbide is quite hard in order to be used in wider array of work than HSS (Broadband Steel).

HSS can’t be as good as carbide burrs when they’re at hot temperature. Carbide Burrs can bear hotness which enable it to run for extended time.

Carbide won’t soften at temperature but HSS burrs is opposite. There is no doubt that carbide is a better choice.

Using Carbide Burs:

For more stability, insert the accessory bit in the unit and then back against each other slightly before tightening down the collet nut or keyless chuck.

Don’t use these for drilling holes or enlarging holes which are under twice the diameter from the cutter. The tungsten carbide surface can easily catch the inside of a hole and break the bit.

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

Start with a lower speed. Then increase to the speed that provides probably the most favourable results.

Usually do not apply excessive pressure. It could decrease the spindle and chip cutting edges. Just let the bur perform cutting.

Use the sides from the cutter for effective cutting. The end cuts poorly and will break under pressure.

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

When using aluminium and magnesium, consider some type of lubricant, wax or tallow, mainly because it will help stop the flutes from loading or packing.

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