Made to perfection

• Long-lasting choice for very hard abrasive materials
• These hole saws create clean holes in materials too hard or abrasive for standard bi-metal saws, or so thin they would strip bi-metal or chip carbide teeth
• Super resistance to heat, wear and abrasion with shock resistant back
• Tungsten carbide grains are bonded to alloy backs with a gulleted snag resistant edge
• CT pilot drill recommended for masonry type materials
