E207 Metric Pitch Spiral Cobalt Machine Tap Bits

• 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-thread<THspace/>entry.
• 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
