Sutton B303 Oval Shape Carbide Burr, 15.9 x 25.4mm, 6mm Shank, Double Cut
Available
The Sutton B303 is a double cut, oval shape carbide burr with a solid carbide (VHM) head and bright finish, supplied with a 6 mm shank.
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 4 sizes, with head diameters from 6.3 to 15.9 mm and overall lengths of 51 to 70 mm, all on a 6 mm shank. 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.
