Beefy 3/4 Inch Weldon Shank Extension For Annular Cutters Cranks Magnetic Drill Reach Way Out To 3 15/16 Inches For Solid Cnc Milling And Serious Deep Hole Drilling Rig

3/4 Weldon Shank Extension Bar For Magnetic Drill Deep Work
✔️ ASTM 5140 heat treated alloy construction offers 3 15/16 inch reach

This single pack extension rod attaches directly to portable or stationary magnetic drill bases to penetrate thick plate steel with minimal vibration. Machine shops and field crews rely on it to maintain stable alignment when boring oversized clearance holes in heavy structural materials.

✅ 3/4 inch Weldon shank mates firmly with most commercial tool holders
✅ Heat treated alloy body resists twisting even when pounding through metal
✅ Arrives exactly as one complete kit wrapped tightly in a protective box

💡 What helps extend magnetic drill reach for deep hole annular cutting?
Adding an extra length bar shifts the cutting action forward so your main rig stays handy during tough runs.
- Longer shaft moves paste zone clear of the magnet base to eject swarf fast
- Hardened rod locks solid against rotational force to stop chatter under load
- Hex profile threads directly into standard collets for quick swapout access
