The Groz Reduction Sleeves, also known as Drill Sleeves, are designed to adapt smaller morse taper shank tools to larger machine spindles.

Manufactured from  case-hardened Hi-tensile steel (20 MnCr5/SAE 8620) this range of sleeves is fully hardened with a ground finish both inside and outside. Precision manufacturing ensures perfect locking and concentric movement of the tool.

The size is permanently marked on the tang for easy identification
