Bi-Metal Hole Saw – Ultimate Cutting Performance for Professionals

Our Bi-Metal Hole Saw represents the pinnacle of hole-cutting technology, combining high-speed steel teeth with a flexible alloy steel back for unmatched performance across diverse materials. Designed for electricians, plumbers, metalworkers, and construction professionals, this cutting tool delivers clean, accurate holes in wood, metal, plastic, and composite materials while outlasting conventional hole saws by 3-5 times. Whether you're installing electrical conduits, piping systems, or HVAC components, this professional-grade hole saw ensures faster cutting speeds, longer lifespan, and reduced operator fatigue.

Key Features & Benefits

• High-speed steel (M42 cobalt) teeth maintain sharpness 5x longer than standard carbon steel

• Variable tooth pitch (4/6 TPI) reduces vibration and prevents material binding

• Precision ground teeth at optimal rake angle for aggressive yet controlled cutting

• Cuts through 1/4" mild steel, stainless steel, aluminum, wood, and PVC with ease

• Bi-metal construction combines hardness (62-64 HRC) with shock-absorbing flexibility

• Fully hardened backing plate prevents distortion under heavy loads

• Laser-welded tooth joints eliminate braze failures common in cheap models

• Special heat treatment extends tool life in abrasive materials

✔ Deep gullets for efficient chip removal (reduces heat buildup)
✔ Universal 3/8" hex drive compatibility works with most drills
✔ Clear size markings (imperial and metric) for quick identification
✔ Included pilot drill ensures accurate hole starting

• Demolition series (thicker backing for reciprocating saw use)

• HVAC cutters (optimized for thin gauge sheet metal)

• Stainless steel specialists (extra cobalt content)

• Non-ferrous models (positive rake for aluminum/copper)
