Toolholders Morse taper DIN 228-1 A (MT)
The Morse taper was developed by Stephen A. Morse, based in New Bedford, Massachusetts, in the mid-1860s. Since then, it has evolved to encompass smaller and larger sizes and has been adopted as a standard by numerous organizations, including the International Organization for Standardization (ISO) as ISO 296 and the German Institute for Standardization (DIN) as DIN 228-1. It is one of the most widely used types, and is particularly common on the shank of taper-shank twist drills and machine reamers, in the spindles of industrial drill presses, and in the tailstocks of lathes.
Material:
Alloyed case hardened steel, tensile strength in the core of min. 800 N/mm²
Case hardened HRC 60 ± 2 (HV 700 ± 50), hardening depth 0.8 mm ± 0.2 mm,
black-finished and precisely grinded.
ISO 296:1974
Machine tools -- Self-holding tapers for tool shanks
