DIN371 Straight Flute Tap
Metric Thread Compliance:
Designed for DIN 371 standard metric threads (e.g., M8×1, M10×1.25), ensuring high-precision thread profiles.
Straight Flute Design:
Chip Evacuation: Optimized for both through holes and blind holes, threading in continuous machining operations.
Rigidity: Superior stability compared to spiral taps, ideal for hard materials.
Material & Coating:
HSS-E (High-Speed Steel with Cobalt): Hardness up to 63-65 HRC, enhanced wear resistance for long tool life.
Optional TiN/TiCN Coating: Reduces friction and extends durability in high-temperature applications.
High-Speed Machining:
Suitable for CNC machines and automatic lathes at speeds up to 15 m/min.
Thread Quality:
Ground Thread Profile: Achieves 6H tolerance class for critical applications.
TYPICAL APPLICATION SCENARIOS
Precision Engineering:
Threading hydraulic valve blocks, precision gears, and bearing housings in alloy steel (e.g., 42CrMo).
Automotive Manufacturing:
Tapping engine cylinder head bolts (threads for high clamping force) and transmission shafts.
Heavy Machinery:
Producing high-strength fasteners and flange connections in carbon steel (e.g., S45C).
Aerospace Components:
Threading landing gear parts and actuator systems requiring DIN standard threads.
General Metalworking:
High-volume production of metric threaded components in workshops with automated equipment.
