12PCS Tungsten Carbide Hole Saw Kit for Hard Metal and Steel, 5/8"-2-1/8"

The ASNOMY 12-Piece Tungsten Carbide Hole Saw Kit provides a dedicated metal-cutting solution for drill presses and hand drills. Designed specifically for tough materials, this set helps metalworkers, fabricators, and DIYers cut clean, round holes in stainless steel plate, iron, cast iron, and sheet metal without quickly dulling the cutting teeth.

Each hole saw features tungsten carbide tipped (TCT) cutters paired with a titanium-plated M2 (6542) steel pilot drill bit. The cutting head uses a three-blade tooth layout that divides cutting duty across outer, middle, and inner edges. This stepped design makes feeding through hard stock faster and more efficient while keeping the cut centered and precise.

The kit covers ten individual diameters between 16mm (5/8-inch) and 54mm (2-1/8-inch), with a standard cutting depth of 25mm (1 inch) and a 10mm (2/5-inch) shank. It pairs with handheld electric drills, bench drills, magnetic drill presses, and percussion drills, handling structural metals as well as wood, F.R.P, and square tubing. Storage is straightforward thanks to an included aluminum box, and two extra pilot bits alongside two hex wrenches are provided for easy maintenance.

Keep in mind that this set is built strictly for metals, wood, and composites. It cannot be used on concrete, tile, or masonry stone. The 1-inch cutting depth also limits single-pass drilling on very thick structural stock.

Verdict: This set is a solid, reliable choice for anyone needing to drill precise holes through tough metals, stainless sheet, or tubing. If you need clean circular cuts in hard stock across multiple shop drills, this boxed kit has the sizes and hardware to get it done.
