BSWBRITISH STANDARD WHITWORTH This thread form was developed by Sir Joseph Whitworth in 1841. The thread form has rounded roots and crests and is specified in BS84:1956. The thread angle for BSW is 55 deg; as opposed to 60 deg; in Metric and Unified threads. Spiral Flute Taps are used for machine tapping in all blind hole applications - especially in soft metals that produce long stringy swarf such as aluminium - copper and magnesium. Manufactured from HSS-Co5 this modern design tap uses the shear action provided by the spiral flutes to draw the swarf out of the hole which minimises swarf clogging when tapping deeper holes.
