Carbon Steel Specific Taps
Universal Spiral Flute Design:
A 40° Spiral Angle optimizes chip evacuation for both blind holes and through holes, making it adaptable to various materials.
Pitch Geometry reduces cutting resistance and prevents chip jamming.
Advanced Substrate & Coating:
New HSSG material: Enhances wear resistance and thermal stability, with hardness exceeding HSSE (65 HRC).
Tic Coating: Reduces friction by 20% and extends tool life by 50% compared to uncoated taps.
Multi-Material Compatibility:
Ideal for carbon steel (SCM440), alloy steel, and various materials.
Suitable for dry cutting or minimum lubrication (MQL) machining.
High-Speed Machining:
Supports CNC operations up to 15 m/min.
TYPICAL APPLICATION SCENARIOS
Automotive Components: Threading engine brackets, gearbox housings, and suspension parts made of mild steel (e.g., AISI 1018/1045).
Construction & Infrastructure: Tapping structural steel beams, fasteners, and metal frames for buildings and bridges.
General Machinery Manufacturing: Producing hydraulic valve blocks, pump bodies, and shaft couplings in carbon steel (e.g., S45C).
Metal Fabrication Shops: High-speed CNC machining of custom brackets, fixtures, and jigs in low-to-medium carbon steel.
