HSS BSW & BSF Spiral Flute Taps for Blind Holes<\/h2>\n

These HSS spiral flute taps are specified for British Standard Whitworth (BSW) and British Standard Fine (BSF) blind-hole threading. The supplied model list includes 12 BSW designations from 1\/8-40 to 1-8, plus 3\/8-20 BSF. Select the complete thread designation and check the nominal diameter, pitch and pilot-hole reference in the size chart. Spiral flutes help carry chips back toward the hole entrance; the required full-thread depth, cutting lead and bottom clearance must be checked for each application. Confirm the spiral flute tool configuration and tool dimensions for the selected size before ordering.<\/p>\n
