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. Large staggered removal slots enables easy extraction of the core. 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. A 5/8-18 thread mounts these hole saws to carbide-tipped arbors - we recommend using Spyder's arbor for diamond hole saws (model 600862). Spyder's diamond hole saws are for use on ceramic, porcelain, granite, slate, marble, glass, cement fiber board, laminates and more; with a 1-1/2-in total depth of cut. Made in the USA.
