Spyder 1/4″ Diamond Edge Arbored Hole Saw Bit 600847

Spyder diamond hole saws are the professional choice for hole-making in tile, glass and masonry materials. Premium boron-coated industrial diamond abrasive self-sharpens for quick cuts and long — up to 20x more holes than standard diamond hole saws and up to 10x faster than standard glass and tile bits. A high temperature nickel braze adheres at temperatures up to 1.5x the temperature of braze used on standard diamond hole saws — increasing diamond abrasive retention and saw life. Heavy-duty, single piece construction and vacuum furnace heat treated high-alloy steel provides a reliable cut and consistent, round holes. These saws can be used wet or dry — water spray or immersion will increase tool life, reduce dust and debris, and will create a more quiet cut. Spyder’s diamond hole saws are for use on ceramic, porcelain, granite, slate, marble, glass, fiber cement board, laminates and more. Made in the USA.
