Shell Mill Arbor

Precision-ground to tight tolerances, these arbors ensure concentric tool seat engagement and rigid torque transfer when mounting indexable face mills and shell cutters to your mill spindle.

Features

• Rigid Tool Engagement: Precision-machined spigot pilot ensures near-zero radial runout, preventing uneven cutter loading and premature insert wear.
• Removable Heavy-Duty Drive Keys: Includes hardened drive keys for positive torque transmission under severe side-loads without risk of keyway shearing.
• Hardened & Precision Ground Alloy Steel: Built to withstand high cutting forces and machine vibration without flex or spindle wear.
• Standard Drawbar Threading: Features standard internal threads across all taper sizes for seamless locking via drawbar or pull-stud setup.
