Carbide Rotary Burrs
Carbide rotary burrs, also known as die grinder bits or rotary files, are used to cut, shape, chamfer, and grind a variety of metals and other hard materials, as well as for removing excess material, sharp edges, and burrs from parts. These burrs are solid carbide, with a bright, uncoated finish. They are available in three cut types, and a variety of common shapes suitable for a wide range of applications.
Applicable Workpiece Materials
P M K S H
Standard Cut
General-purpose design that offers good metal removal, and provides a smooth finish. Produces longer chips, and is excellent for cutting relatively hard materials that won’t clog the flutes.
Applications:
• Heavy material removal
• Milling
• Deburring
• Cleaning
Applicable Workpiece Materials
P M K S H
Double Cut
Offers rapid material removal in harder materials, with minimum chatter. The cross-cut design prevents chip loading of the flutes, and produces smaller chips. The intersecting flutes also reduce pull, increasing operator control, and provide a smoother finish than standard cut.
Applications:
• Medium-light material removal
• Deburring
• Fine finishing
• Cleaning
Applicable Workpiece Materials
N
Aluminum Cut
Recommended specifically for use on softer materials, like aluminum, copper, and brass. The wide flute design runs cooler, and offers fast material removal on non-ferrous metals, with minimal flute clogging.
Applications:
• Rapid material removal
• Milling
• Deburring
• Cleaning
SB – END CUT CYLINDER
Good for deburring and finishing flat-bottom holes and slots. Designed for both end and side cutting.
SC – RADIUS END CYLINDER
Good for deburring inside areas with a shouldered radius, or for round-bottom holes, convex slots, and other curved surfaces. Can also be used to prepare metal edges for welding.
SD – BALL
Good for deburring round-bottom holes, convex slots, and curved metal and material surfaces. Can also be used to enlarge or elongate small holes, and to dress hard fillet welds.
SF – RADIUS END TREE
Good for deburring and finishing deep contoured surfaces in steel dies, molds, and metal patterns. Can also be used for repairing slug-damage spots on dies.
SG – POINTED END TREE
Good for deburring and finishing the curved top inside wall of steel dies, castings, forgings, or metal patterns. Can also be used to repair slug-damage spots on dies.
SH – FLAME
Good for deburring and finishing elliptic surfaces in steel dies, forgings, castings, and metal patterns.
SJ – 60° CONE
Good for deburring, enlarging, or chamfering countersink holes, repairing 60° threads, V-grooves, and other angular surfaces. Can also be used to prepare metal edges for welding.
SL – TAPER
Good for deburring and removing scale in steel die and mold cavities.
SM – 14° TO 28° CONE
Good for deburring gear teeth, heat exchanger fan blades, inside bevel edges, and internal pipe edges.
SN – INVERTED CONE
Good for deburring and finishing dovetail slots, gib blocks, and other inverted angular metal and material surfaces.
