Bi-Metal Hole Saw Kit, HYCHIKA 17 Pcs High Speed Steel 3/4" to

The HYCHIKA 17-Piece Bi-Metal Hole Saw Kit provides a comprehensive set of cutters designed to bore clean holes through wood, plastics, drywall, and soft metals. Built for DIYers and craftspeople needing multiple diameter options, this package eliminates the need to buy individual hole cutters for home improvement projects.

Each saw blade uses a 2mm-thick bimetallic body paired with high-strength alloy steel teeth hardened to 69 to 81 HRC. This construction resists wear and improves overall toughness during use. To keep cuts efficient, the blade profile features side chip-removal grooves that discharge material buildup rapidly, preventing binding while maintaining smooth edges.

With eleven blade sizes ranging from 19mm up to 68mm, the set adapts easily to plumbing, electrical, and carpentry tasks. The saws deliver a maximum cutting depth of 40mm. The package also provides two mandrels, three pilot drill bits for quick replacement when worn, and a hex key, all housed inside a small, sturdy storage case.

While versatile, this kit has clear boundaries. It is designed for soft metals, PVC boards, plastic, gypsum boards, and wood, so it is not suited for cutting dense hardwoods or heavy structural metals. Buyers should also verify that the 40mm depth rating fits their specific workpiece thickness before drilling.

Verdict: This HYCHIKA set is an ideal choice for homeowners and hobbyists who need a broad selection of hole diameters for everyday drywall, plastic, and soft metal cutting. It delivers essential accessories in one portable box, making general workshop tasks much simpler.
