FEWELL 16PCS Bi-Metal Hole Saw Set

When drilling through metal, wood, or composite materials, professionals demand tools that deliver speed, accuracy, and relentless durability. The FEWELL 16PCS Bi-Metal Hole Saw Set is engineered to outperform standard hole cutters, blending aerospace-grade materials with intelligent design for contractors, electricians, and serious DIYers.

Why Choose This Hole Saw Set ?

1. Cobalt-Infused M42 Steel: Cut Harder, Last Longer

• 8% Cobalt Teeth: Unlike ordinary bi-metal blades that dull after 20-30 cuts on steel, our M42 alloy with 8% cobalt retains sharpness through 100+ holes in 3mm sheet metal (lab-tested).

• Heat & Wear Resistance: The cobalt matrix reduces friction by 40%, preventing edge deformation when drilling stainless steel, PVC, or hardwood.

2. 11 Sizes Suitable for Every Project

From HVAC ducting (51mm/2" holes) to plumbing pipe fittings (64mm/2.5"), this set covers 90% of standard applications:

• Full Range: 3/4"(19mm) to 2-1/2"(64mm) in 1/8" increments

• Zero-Tear Design: Anti-wobble pilot bits eliminate splintering in oak doors or cracking in ceramic tiles.

3. Engineered for Speed

• Deep Gullet Geometry: Angled teeth and 2x wider slots (vs. generic saws) eject wood chips/metal shavings instantly, reducing drilling time by 50%.

• Impact-Ready Arbor: Hardened 10mm hex shank withstands 2,500 RPM on rotary hammers—ideal for concrete anchor holes.

Designed for Professionals

Tool-Free Blade Swapping

Switch between sizes in 3 seconds with the quick-release mandrel—no wrench needed. The arbor's dual spring-loaded ball bearings lock blades securely, even under vibration.

Portable & Protected
