HTC SL-3NF Cone Radius End Style Carbide Burr 1/4" SH, 3/8" D, 1-11/16" CL

For use with 1/4" chuck die grinders.

Non-Ferrous (NF) or aluminum cut burrs have a more open, aggressive cut to avoid loading on softer materials. This design provides excellent stock removal on aluminum, magnesium, copper, soft steel, brass, zinc alloys, hard rubber, most plastics, and non-ferrous metals. NF burrs feature easy chip flow with little to no clogging.

Helpful application tips:

• Insert shank as far as possible into the chuck - this will help prevent whipping or chatter.
• Use just enough pressure to keep the burr cutting; excessive pressure will slow spindle speed and damage the cutting edge.
• Keep the burr moving at all times to prevent it from digging into the work.
• Do not run burr beyond point of normal resharpening; the heat and pressure will cause excessive chipping of the cutting edge.
