💡 What steps prevent a hole saw blade from walking off center when boring into hard steel plates?
Locking the mounting gear eliminates lateral movement before the pilot tip touches the face.
- Rigid six sided shaft transmits full rotational power without spinning freely
- Matched pilot extensions seat heavy teeth evenly against the outer cutting ring
- Deep groove channels haul debris away so the kerf never drags the drill sideways
