Designed for professional durability, this hole saw features a premium bi-metal construction infused with 8% cobalt alloy (M42). This advanced metallurgy provides superior heat resistance and extends the cutting life of the teeth, making it an excellent choice for demanding applications in both wood and metal. Whether you are boring through dimensional lumber, plywood, aluminum, or mild steel, this tool delivers consistent, reliable performance hole after hole.\u003c\/p\u003e\n\u003cp\u003eEfficiency is built into the design with Bosch's innovative \"Progressor\" tooth geometry. The variable 5 TPI (Teeth Per Inch) configuration cuts faster and cleaner by effectively clearing chips and reducing vibration during operation. To withstand the high torque of modern drills, the cup features a reinforced shoulder that adds critical strength, preventing ovaling and breakage. Compatible with standard threaded arbors and adaptable for Quick Change™ systems (adapter sold separately), this versatile hole saw is a staple for any serious toolkit.\u003c\/p\u003e\n\u003ch3 style=\"color: #0056b3; border-bottom: 1px solid #ccc; padding-bottom: 5px; margin-top: 25px;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"margin-bottom: 25px;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Durability:\u003c\/strong\u003e 8% Cobalt alloy construction resists high heat for longer life in tough materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast Cutting Action:\u003c\/strong\u003e Progressor tooth design with 5 TPI variable pitch ensures rapid, clean cuts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforced Strength:\u003c\/strong\u003e Shoulder design adds structural integrity to withstand high-torque applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Application:\u003c\/strong\u003e Optimized for cutting wood, metal, plastic, and composite materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeep Cut Capacity:\u003c\/strong\u003e 1-5\/8 inch cutting depth easily handles 2x lumber and thick materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Fit:\u003c\/strong\u003e Works with standard mandrels and is compatible with Quick Change systems (adapter required).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #0056b3; border-bottom: 1px solid #ccc; padding-bottom: 5px; margin-top: 25px;\"\u003eWhat's Included\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 25px;\"\u003e(1) 1-9\/16 In.
