You use Machine Tap DIN 376 Form B HSSE left hand thread - BSW 1" x 8 LH to generate threads during manufacturing, maintenance, or repair work. Correct results depend on matching the tool to the specified thread designation and keeping the tool aligned to the axis.
BSW means British Standard Whitworth, an inch based Whitworth thread form found on legacy equipment and repair work. 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 indicates a cobalt alloyed high speed steel grade, often used when the cut is demanding or heat input is higher.
Note Clean threads and tools before use, apply suitable lubrication for cutting operations, and stop if resistance rises sharply.
