Sutton B220 Taper Radius End Carbide Burr, 1/2" x 1-1/8", 1/4" Shank, Aluminium Cut
Available
The Sutton B220 is an aluminium cut, taper shape radius end 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 1/2" (12.7 mm) to 3/4" (19.1 mm) and overall lengths of 2-7/8" (73 mm) to 3-1/4" (82.6 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, blending and finishing in tapered, angled and tight areas
- Cleaning up weld in Vee joints and corners
- Finishing recesses, where the radiused tip avoids leaving a sharp corner
- 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
Design features
- Al Cut pattern: for rapid stock removal of soft materials such as aluminium, brass, copper and plastics that would normally load other cuts
- Solid carbide (VHM): VHM construction is designed to give optimum strength, hardness and wear resistance
- Bright finish
- Head profile: tapered, with a radiused end
- Shank: 1/4" (6.35 mm), for standard 1/4" die grinder collets
Sizes
Dimensions: d1 is the head diameter, l2 the cut length, l1 the overall length and d2 the shank diameter, with the angle where the catalogue gives one. Imperial sizes are shown with the metric equivalent in brackets.
