A range of metric pitch spiral cobalt machine tap bits. These tap bits meet stringent high-production machining demands due to significant resistance to wear and high temperatures. These tap bits have a short 2-threadentry. The tolerance class of these tap bits is 6H, the cutting angle is 12°, the spiral rake angle is 15° right and the shank is reinforced. These top quality tap bits are ideal for operations in blind holes on materials with a tensile strength of approximately 750 N/mm2.
Standard: DIN 371
Rolled Flute Taps
Bright finish fluteless taps; for use on copper, aluminium, magnesium, brass, zinc etc. Flash chrome finish fluteless taps; for use on steel up to 850N/mm2 tensile strength, free matching and austenitic stainless steel Made to ISO529 standard for tapping blind and through holes in a wide range of ductile materials Smooth non-cutting action produces greater thread formed strength, higher life expectancy and increased tapping speeds especially where excessive tension occurs
