Drill America Bi-Metal Hole Saws — M42 Cobalt Teeth for Fast, Clean Cutting in Metal & Wood
The Drill America Bi-Metal Hole Saws are designed for versatile, high-performance hole cutting across a wide range of materials. Manufactured with M42 cobalt high-speed steel teeth welded to a tough alloy steel body, these hole saws deliver an ideal balance of cutting speed, durability, and flexibility for professional and industrial use.
The bi-metal construction allows the cutting edge to stay sharp longer while the flexible body absorbs vibration and resists tooth breakage. This makes Drill America bi-metal hole saws suitable for metal, wood, plastic, drywall, and composite materials, providing clean, accurate holes with reduced chatter.
Precision-set teeth and optimized gullets ensure efficient chip removal and smoother cutting action, even in harder materials like mild steel and stainless steel. Available in a wide range of diameters, these hole saws are compatible with standard arbors and are ideal for electricians, plumbers, HVAC installers, fabricators, and maintenance professionals.
