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. Oversized core removal slot enables easy side evacuation of the core, without tools or prying (for materials up to 5/8-in in depth). A 1/4-in speed hex won’t slip in the chuck. 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.
