Machine Tap DIN 376 Form C 35° SP HSSE left hand thread - BSW 1" x 8 LH by VÖLKEL, item no. 70239, suitable for cutting internal threads.
With Machine Tap DIN 376 Form C 35° SP HSSE left hand thread - BSW 1" x 8 LH you create a thread interface that must assemble without force. Preparation of the hole or blank and steady alignment are the practical checkpoints for repeatable threads.
BSW identifies the Whitworth inch thread series, common in refurbishment and service of older mechanical assemblies. Left hand thread means the tool is intended for threads that tighten opposite to standard right hand threads. DIN 376 indicates the referenced standard family or tool standard named in the product designation. HSSE denotes cobalt alloyed HSS, commonly used for more demanding threading conditions.
Note Clean threads and tools before use, apply suitable lubrication for cutting operations, and stop if resistance rises sharply.
