💡 How does a pneumatic pencil die grinder manage recoil and chip accumulation when drilling out broken fasteners from thick steel plates?
The 70000 RPM motor provides plenty of bite to eat through rusted studs while keeping rotation steady so you dont strip the surrounding threads.
- Upgraded tungsten gears keep this handy grinder spinning true even when forcing the bit through hardened alloy components under pressure
- Lightweight pen form factor drops right into deep wells and blind holes making quick work of jammed bolts near tight frame edges
