Trumil - Drill Sleeve or reduction sleeve is made from high-quality material. The manufacturers use 20MnCr5; case hardened to 55-58 HRc. The Drill Sleeve has a concentricity within 0.015 mm. This tapered, hollow steel shaft is ideal for a tapered shank of a cutting tool and adapts it to the drill press spindle. The Drill Sleeve provides protection and helps prevent the drill bit from slipping. It allows you to adapt smaller MT shank tools to the longer machine spindles. It has precisely controlled taper angles to enable perfect locking to the tool.
