💡 What makes a bi-metal hole saw handle hard metals better than standard carbide punches?
This design pulls double duty by blending two different steels into one reliable cutter that saves your budget on tough jobs. Here is why it stays handy around the shop:
- Dual layer build locks aggressive teeth to a flexible backing plate that eats through thick stock without chipping
- Cobalt enriched alloy raises the temperature ceiling so you can grind through stainless sheets without ruining the gear ratio
- Maintain even pressure and use plenty of slick oil to flush out burrs and keep the cut path clean every single time
- Swap out the pilot bit quickly to match your drill press chuck and track smaller inner circles for precise mounting holes
