K+M Collets for Case Holder

Description

Give your hands a break from grasping cases with the all-new Case Holder from K+M (sold separately).

Collets available for case bodies up to .563″ diameter (14.3mm).

Secure a wide range of cases for primer pocket work (head-facing) and, for most rimless cases, case mouth work (neck-facing).

This tool accepts hundreds of cartridges thanks to a wide range of collets.

Notes:

• Collets sold individually
• Lightly oil collets for enhanced corrosion protection
• Not compatible with CheyTac and BMG cases
