About this product
Cut Through Metal, Wood, and More — Without Changing Tools.
Standard carbon steel hole saws dull fast on metal and give you rough, splintered cuts on wood. The HYCHIKA 17-Piece Bi-Metal Hole Saw Kit solves both problems. Bi-metal construction means harder teeth, better toughness, and cuts that stay clean through dozens of jobs — on soft metal, wood, drywall, PVC, and plastic.
Why Bi-Metal Beats Carbon Steel for Tough Materials
- 🔩 Bi-metal blade construction — high-speed steel teeth on a flexible alloy body. Resists snapping, stays sharper longer, and handles vibration without tooth loss.
- ⚡ Optimised tooth geometry — higher cutting efficiency, cleaner cut edges, and less heat build-up compared to standard carbon steel saws.
- 🛠️ Chip removal groove design — clears swarf quickly during cutting so the blade doesn’t clog and overheat.
- 📐 11 blade sizes — 19 / 22 / 25 / 29 / 35 / 38 / 44 / 51 / 57 / 60 / 68mm. Covers electrical boxes, conduit holes, door hardware, and more.
- 📆 40mm max cutting depth — 60% deeper than standard carbon sets, ideal for thicker timber, steel sheets, and layered materials.
- 🗄️ Storage case included — sturdy compact box keeps all 17 pieces organised and protected on the job site.
