3/8" x 5/16" 1/4" Shank Dia Blackstone SD-3 Ball Nose Double Cut Carbide Burr

Description

3/8" x 5/16" 1/4" Shank Dia Blackstone SD-3 Ball Nose Double Cut Carbide Burr.
Condition is New
Applied for deburring, chamfering, milling out for the preparation of build-up welding, machining of welded joints, machining of contours, cleaning cast material, trimming, cutting out holes.
High wear resistance and long life.
Sharp cutting edge and fine finish.
100% testing on welding strength, assurance for user's safety.
Well designed cutting angle for optimal cutting efficiency and stability.
Work with maximum RPM in the recommended cutting speed.
Adopt correct chuck to clamp cutter shank. Chucks and collets must be absolutely concentric to avoid chipping and premature wear. Over two-thirds of length must be clamped to ensure safety.
Turn on the power or air tools after the burrs touch the work piece for safety reasons. Do not move the cutter from the work piece when using, and turn off the power or air tools before any movements.
Avoid reciprocation in processing which may cause cutting edge breaking and premature wear. Follow the order from right to left.
Reduce RPM when processing on one location continuously or materials with low heat conductivity. Never let the shank and head become discolored blue due to overheat, which will result in lower welding strength.
When machining very sticky materials, the use of a suitable lubricant is recommended to prevent blocking in chip space.
