Sutton B210 Cylindrical Square End Carbide Burr, 3/8" x 3/4", Double Cut, Long Reach

The Sutton B210 is a long reach, double cut, cylindrical square end carbide burr with a solid carbide (VHM) head and bright finish, supplied with a 1/4" (6.35 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 2 sizes, with head diameters from 3/8" (9.5 mm) to 1/2" (12.7 mm) and overall lengths of 6-3/4" (171.5 mm) to 7" (177.8 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 cut at a reduced speed, with cutting speeds reduced by 50% for long shank carbide burrs.

Where this burr is used

• Grinding and deburring flat surfaces, square corners and edges with the side and the flat end of the burr
• Squaring up and cleaning out slots, pockets and keyways
• Removing weld bead, flash and casting fins
• Steel and stainless steel: recommended speeds are given below for steels and alloys and for stainless steel
• Weld cleanup, deburring and shaping in fabrication, toolroom, foundry, engineering workshop and maintenance (MRO) work

Design features

• Double cut (chisel tooth) pattern: for rapid stock removal in the harder materials, with minimal tool chatter and a granular chip in most materials
• Solid carbide (VHM): VHM construction is designed to give optimum strength, hardness and wear resistance
• Bright finish
• Head profile: cylinder with a flat (square) end
• Shank: 1/4" (6.35 mm), for standard 1/4" die grinder collets
• Long reach: 6-3/4" (171.5 mm) to 7" (177.8 mm) overall length for reaching into deeper recesses

Sizes

Dimensions: d1 is the head diameter, l2 the cut length, l1 the overall length and d2 the shank diameter. Imperial sizes are shown with the metric equivalent in brackets.

Recommended cutting speeds

Recommended speeds by head diameter, from Sutton's cutting speed guide for standard length burrs. These burrs are long reach, so reduce the speeds shown by 50%.
