Hole-saw Tungsten-carbide Grit Integral-arbor 1"

Cutting edge of tungsten carbide particles bonded to alloy steel back cuts extremely hard abrasive materials. High heat and abrasion resistance, no teeth to dull or chip, resists snagging, smooth cutting, greater wear resistance. Used in applications such as laminates, fiberglass, ceramic tile, marble and slate, cast iron or composites, 1/4 in quick-change shank.
