BPTL manufactures tool holders with the industry-standard 7/24 taper interface (which includes BT (MAS403/JIS B 6339), DV (DIN 69871) and CV (ANSI B5.50/ISO 7388)) and also HSK (DIN 69893) Tool Holder Taper pays two crucial roles during machining: provide rigidity to the tool and to precisely hold the chuck in position while machining.
The different sizes of tapers are used for light to heavy machining, depending on the user's needs. BPTL has been manufacturing tool holders since 1937. BPTL tool holders are grounded with AT 3 class accuracy, making them suitable for Hi-Speed and Hi-Accuracy Machining.
BPT Mechanical Holder is manufactured with AT3 taper tolerance accuracy, which follows the dimension of international standards.Read More
