Sutton B217 Ball Shape Carbide Burr, 1/4", 1/4" Shank, Aluminium Cut
Available
The Sutton B217 is an aluminium cut, ball shape carbide burr with a solid carbide (VHM) head and bright finish, supplied with a 1/4" (6.35 mm) shank.
The Al Cut pattern is for rapid stock removal of soft materials such as aluminium, brass, copper and plastics that would normally load other cuts.
This listing covers 5 sizes, with head diameters from 1/4" (6.35 mm) to 3/4" (19.1 mm) and overall lengths of 2" (50.8 mm) to 2-7/16" (61.9 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.
