Sutton B218 Oval Shape Carbide Burr, 1/2" x 7/8", 1/4" Shank, Aluminium Cut
Available
The Sutton B218 is an aluminium cut, oval 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 3 sizes, with head diameters from 3/8" (9.5 mm) to 5/8" (15.9 mm) and overall lengths of 2-11/32" (59.5 mm) to 2-3/4" (69.9 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.
Where this burr is used

- Deburring and fettling where a rounded profile is needed
- Aluminium, brass, copper and plastics: soft materials that tend to load a standard cut
- Weld cleanup, deburring and shaping in fabrication, toolroom, foundry, engineering workshop and maintenance (MRO) work
