Long-Life Grinding Bits for Metals

Similar to diamond, boron nitride is harder than aluminum oxide and lasts longer. Bits are also known as jig grinding pins and mandrels.
Head diameter is measured at the widest point.
Caution: As bit shank is exposed beyond 1/2", maximum safe rpm decreases significantly. Refer to ANSI standard B7.1. Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Long-Life Grinding Bits for Nonmetals








The diamond abrasive in these bits is extremely hard and lasts longer than tungsten carbide. For longer tool life and improved finish, use a water- or oil-soluble mist or coolant.
Bits are also known as mounted points and die grinder bits. Head diameter is measured at the widest point.
Caution: As bit shank is exposed beyond 1/2", maximum safe rpm decreases significantly. Refer to ANSI standard B7.1. Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

No-Mess Polishing Bobs for Stainless Steel and Hard Metals



The long-lasting diamond abrasive is already embedded in these bobs so you don’t need messy compounds. Polish small areas and hard-to-reach spots using a drill or grinder for bits and burs. Grit is approximate.

Flexible Cylinder Hones for Hard Metals

A long-lasting diamond abrasive is embedded in balls at the ends of flexible spindles that press against the inside of a cylinder to remove material and leave a smooth, even finish. These hones are slightly oversized to maximize contact with the work surface. When your cylinder ID falls between two sizes, order the larger hone. Use with portable drills, drill presses, and CNC machines. Hones should be rotating when inserted into or removed from cylinders. We recommend using them with honing oil to keep the abrasive surface clean.
Abrasive material is identified by the color on the stem.
Grit is approximate and identified by the color on the hone tip.
Also Available: Hones made of boron carbide, alumina zirconia, levigated alumina, ceramic, and cubic boron nitride. Please order 4424A999 and specify abrasive, cylinder ID, and grit. Grit availability varies by abrasive.

Long-Life Hole Saws for Ceramics and Masonry


For 9/16"-1 3/16"
Dia. Saws

for 1 1/4" Dia.
Saws or Greater
The diamond-grit edge on these hole saws cuts more accurately, leaves a smoother finish, and lasts up to twice as long as carbide-grit-coated teeth. Saws are for use on reinforced plastic, Kevlar, stone, brick, and other abrasive materials with high silicon content. Attach them to a drill or drill press. An arbor with pilot drill (sold separately) is required. To cut ceramic tile, you must use a 1/4" carbide-tipped pilot drill.

Long-Lasting Sanding Brushes with Shank for Tight Spaces

The abrasive lasts longer than that of standard brushes. The grains are embedded in the entire length of the bristles so the sides act like flexible files. These small-face brushes can access hard-to-reach spots to remove workpiece material as well as surface contamination in a single step. The bristles won’t leave behind debris that could cause rust on your workpiece.
