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-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
