DURABLE M42 COBALT PERFORMANCE FOR HEAVY-DUTY CUTTING
Achieve superior cutting results and extended tool life with the Bosch HBT387 3-7/8 Inch Bi-Metal Hole Saw. Engineered for the demands of professional job sites, this hole saw is constructed from Bosch’s enhanced M42 alloy material, featuring 8% cobalt. This high-grade composition provides excellent heat resistance, allowing the blade to withstand high temperatures and delivering up to 20% longer life compared to standard bi-metal saws. Whether you are drilling through tough metal, stainless steel, wood, or drywall, this tool ensures clean, precise cuts every time.
The HBT387 is designed for maximum efficiency and ease of use. It features the innovative "Progressor" tooth design with a 5 TPI configuration, which allows for faster cutting speeds and cleaner edges. The unique triangle "shark tooth" side slots effectively dissipate heat and solve the common frustration of stuck plugs, making debris removal quick and simple. With a reinforced shoulder for added strength against high torque and a deep cup to handle thick materials, this hole saw is a versatile and reliable addition to any toolkit.
Key Features
- M42 Cobalt Alloy: Contains 8% cobalt for superior heat resistance and up to 20% longer life in tough materials.
- Progressor Tooth Design: Alternating tooth sizes (5 TPI) ensure faster cutting and cleaner holes.
- Triangle Slot Design: "Shark tooth" side slots allow for easy plug ejection and improved heat reduction.
- Reinforced Shoulder: Adds structural strength to the base to prevent failure under heavy loads.
- Deep Cup Capacity: 1-3/4 inch depth allows for drilling through thicker materials like 2x lumber and composite layers.
- Multi-Material Versatility: Optimized for cutting wood, metal, plastic, drywall, and stainless steel.
