(38mm | 1-1/2 Inch) HSS M42 with 8% Cobalt Bi-Metal Hole Saw

The REKCKRUL 1-1/2 Inch (38mm) Bi-Metal Hole Saw is a dedicated cutting tool designed for clean circular cutouts in residential and DIY installations. Built to fit standard drills, it gives DIYers and tradespeople a reliable way to bore holes for items like recessed lights, vent pipes, speakers, and cornhole boards without tearing up the work surface.

Construction relies on M42 high-speed steel teeth containing 8 percent cobalt welded to a flexible steel body. This bi-metal build manages friction heat while maintaining tooth sharpness across repeated uses. The blade geometry incorporates sharp teeth alongside deep gullets that clear chips rapidly, paired with a non-binding edge design that keeps the cup moving smoothly through the material instead of binding or jamming mid-cut.

Setup is straightforward thanks to the included arbor and locking pin mechanism. Aligning the pins, rotating the arbor, and tightening the hex-key system creates a solid connection between the drill chuck and the saw, minimizing wobble during operation. In addition to standard wood and drywall, the blade handles plastic, PVC, fiberglass, plywood, and thin metals. The package includes the hole saw, the arbor with an attached pilot drill bit, an extra replacement drill bit, and the necessary hex key.

As a single fixed-size 38mm cutter, its primary limit is diameter flexibility. You will need separate accessories if your project requires different hole sizes. Additionally, while it handles thin metals, it is not specified for thick steel plate or masonry work, so users must stay within the listed material limits.

Verdict: This REKCKRUL hole saw kit is a smart, capable choice for anyone tackling light remodeling or woodworking tasks that require exact 1-1/2 inch openings. With its durable cobalt construction and included spare pilot bit, it provides everything needed for clean, jam-free drilling right out of the box.
