💡 What causes bits to slip or wander when pushing hard through dense material?

A tight internal taper keeps the shank seated firm while absorbing torque shocks.

- Tempered metal walls fight heat fatigue so they hold their grip longer

- Precise outer ground surfaces spin smooth to stop wandering on rough pass

- Handy stamped codes cut down search time when mixing up project materials
