Which hole saw do you need?
Match the hole saw to the material and the thickness.
| Cutting into | Use | Because |
|---|---|---|
| Wood, MDF, plasterboard, plastics | Bi-metal | The everyday hole saw. HSS teeth on a flexible body, 4/6 TPI clears chips fast. Cheapest per size, 22 to 210mm. |
| Mild steel, cast iron, aluminium | Bi-metal / Cobalt M42 | Bi-metal copes with the odd hole. Cutting metal all day, M42 holds its edge far longer. |
| Stainless steel, hard or high-tensile steel | Cobalt M42 | Stainless work-hardens and blunts bi-metal teeth fast. 8% cobalt keeps cutting under the heat. 14 to 210mm. |
| Thin sheet steel, stainless and aluminium up to 1.6mm | Rot8 | A standard hole saw grabs and tears thin sheet. Rot8 has a built-in pilot, depth stop and ejector spring, so it cuts clean and pops the slug out. 18 to 32mm. |
| Porcelain, ceramic tiles, glass, granite, marble | Diamond M14 / Diamond Hex | Teeth shatter tiles. Diamond grinds a clean hole with no chipping. M14 fits an angle grinder, hex shank fits a drill. 6 to 100mm, use wet. |
| Brick, block, concrete walls | Core drills | Hole saws are not for masonry. A dry diamond core drill cuts through the wall in one go. |
| A range of sizes for the van | Hole saw sets | 8pc and 13pc cobalt M42 sets with arbors and pilot drills in a case. Cheaper than buying the sizes one at a time. |
Every hole saw needs an arbor to fit your drill: Arbor A or B for 14 to 30mm, Arbor C for 32mm and above, both with the pilot drill included. Rot8 has its own built in.
