CARBIDE BURR SELECTION AND USE:

The first step in selecting the proper burr is to pick the best shape and cut style.

• Selection of shape and diameter should be based on the work piece, and the operation to be performed.


• Burs have 13 basic shapes:

 

Burs come in 7 kinds of flute style as following.

6 - Double Cut: Very efficient stock removal. Creates a small chip. Good finish. Excellent operator control.
3 - Single Cut: General purpose fluting. Produces long chips.
1 - Nonferrous: For nonferrous materials. Aggressive stock removal.
3SP - SP Chip Breaker: Provides breakdown in chips. Better control.
4 - Diamond Cut: For heat treated and tough alloy steels where control is important. Creates a powder-like chip. Excellent finish.
2 - Coarse Cut: Provides large flute area for softer ferrous materials. Fast stock removal.
5 -Fine Cut: For general use on hard materials requiring a fine finish.

 

Selection of cut would be based on the material, and finish required.

 

The second step in selecting the right tungsten carbide grade.

We have metric size and fractional size for industrial carbide burrs. Meanwhile, we have 3 kinds of different carbide grades named K30, K25, K20 for carbide burrs.

Grade	Cobalt	HRA	HRC	Density  (ISO 3369)	Transverse rupture strength (ISO 3327)
K30	8%	89.3-89.5	74.3-74.6	14.8	2000
K25	7%	89.5-90.5	74.6-77	14.9	2650
K20	6%	90.1-91.5	76.2-78.4	14.7- 15	1800

 

The third step in selecting the right rotary speed for SYNDENT carbide burr.

These are general speed recommendations that may need to be adjusted for special application
