Long-Life Hole Saws for Ceramic and Masonry


	Arbor with Pilot Drill	Arbor with Pilot Drill

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.

Diamond-Coated Router Bits for Composites

With a diamond coating, these bits resist wear when used on abrasive materials, making them last about 50 times longer than uncoated bits. Their sharp cutting edges and flute shapes are specifically designed to cut through tough materials such as composites with minimal resistance. This means less strain on your router and more control when cutting, leading to a smooth cut. Bits are made of solid carbide for longer tool life and faster cutting speeds than high-speed steel.

Drill/Mill Cut Style—Bits with a drill/mill cut style have a pointed end for easier plunge cuts than square-cut bits.

Plunge Cut—Plunge-cutting bits let you cut directly into the workpiece from above. Other bits are best for operations where the peripheral teeth do most of the work such as trimming, contouring, and finishing.

Straight Flutes—Bits with straight flutes are for general purpose use. They quickly remove material, leaving a rough finish.

Diamond-Pattern Flutes—Diamond-pattern flutes' small, staggered teeth aggressively cut, yet leave a smooth finish.
