Steep taper to DIN 69871 Form AD Case-hardened and ground for precision fit Accepts tools with Morse taper and drive lugs Projection A 50 mm, diameter 32 mm, MK2 Secure retention and reduced runout for productive machining The taper sleeve is designed to the DIN 69871 Form AD standard and finished to ensure consistent seating in SK40 spindles. The steep taper geometry, combined with the MK2 interface, delivers a stable mechanical connection that minimises axial and radial play during rotation. For machining operations where accuracy matters, the precise fit reduces tool runout and contributes to repeatable results, making the sleeve suitable for both routine workshop tasks and small-series production. Long service life through surface treatment and machining accuracy Manufactured case-hardened and subsequently ground, the sleeve offers enhanced wear resistance at the taper contact zones while preserving the axial geometry required for repeatable seating. This heat-treated surface limits fretting and surface wear when accepting tools with a Morse taper and drive lugs, extending service intervals and maintaining clamping accuracy over time. The ground finish also facilitates straightforward cleaning and inspection, supporting reliable process quality with minimal maintenance. Standardised dimensions for easy integration and inventory management With a projection A = 50 mm and a diameter of 32 mm, the sleeve is dimensioned for predictable tool projection and clear clearance planning in SK40 toolholders. The MK2 receptacle permits use of a wide range of Morse taper tooling, simplifying tool inventory by enabling interchangeability across machines that conform to the DIN 69871 system. Clear standardisation reduces setup time and supports process planning where tool length and concentricity are critical.
