MAS BT JIS B 6339

The steep taper clamping tools program 

is especially designed to accept boring, reaming and counterboring tools with straight or tapered shank, milling cutters and tapping tools. 

WOHLHAUPTER clamping tools are made of case-hardened steel and precision ground at the points of connection with the machine and the tool. 

Steel: case-hardened of at least 950 N/mm² core tensile strength 

Hardness: HRC 58 ± 2 

Taper tolerance AT 3 to DIN 7178 / 2080

Reduction sleeves for 7/24 ISO taper shanks

Adaptor sleeves for morse taper shanks

Adaptor sleeves for parallel shanks DIN 1835B
