Heavy Duty Ground Manganese Steel Er20A Shaft Extender Sleeve For Deep Hole Cnc Milling And Lathe Tooling Featuring Rock Solid Rigidity That Shoots Straight Quick One To Thirteen Millimeter Swap And Zero Play For Shop Pros
✔️ Hardened manganese steel sleeve extends cutting depth smoothly
A ground manganese steel sleeve bridges the gap between your collet chuck and the cut point, delivering steady support where stock cutters run out of reach. Machine shops lean on this rigidity for deep slot milling and extended turning jobs that refuse to wobble. Dimensions call for a fifty millimeter (1.97 inches) overall body, a nineteen millimeter (.75 inch) straight shank profile, and a one to thirteen millimeter (.04 to.51 inch) grip window.
✅ Factory balanced outer wall cuts harmonic shake during aggressive passes✅ Tight fit design locks onto drill arbors and end mills without slip
✅ Rigid alloy body absorbs torque spikes while keeping your feed rate steady
✅ Clean surface finish slides right into most standard taper holders
💡 How does extending a tool shank improve precision machining results?
- Solid core geometry locks into the chuck to eliminate chatter
- Longer reach allows you to hit deep slots without swapping bits
- Reduced swing weight keeps your spindle tracking straight while cutting
- Sturdy build stays handy when pushing material removal rates harder
