Sutton B208 Cone Shape Carbide Burr, 5/8" x 1-1/8", 1/4" Shank, Double Cut
Available
The Sutton B208 is a double cut, cone shape carbide burr with a solid carbide (VHM) head and bright finish, supplied with 1/4" (6.35 mm) shanks on 6 sizes and 1/8" (3.2 mm) shanks on the 3 smallest.
The double cut (chisel tooth) pattern is for rapid stock removal in the harder materials. The chisel tooth pattern is designed to minimise tool chatter and reduce the chip to a granular shape in most materials.
This listing covers 9 sizes, with head diameters from 1/8" (3.2 mm) to 5/8" (15.9 mm) and overall lengths of 1-1/2" (38.1 mm) to 2-7/8" (73 mm). Dimensions are as published in Sutton's catalogue.
Fit it to a die grinder or other high-speed rotary tool with a collet that matches the shank, and keep to the recommended speeds for the head diameter shown below.
Where this burr is used
- Chamfering and countersinking edges
- Deburring hole edges and chamfers
- Grinding angled surfaces and Vee grooves
- Steel and stainless steel: recommended speeds are given below for steels and alloys and for stainless steel
