Machining threads in hardened steel plates (up to HRC 35) has long been a bottleneck due to rapid tool wear. The M4 tap and drill set breaks through these limitations with a combination of durability and precision.
Built for Brutal Conditions
M35 HSS (8% Cobalt): Retains hardness up to 600°C, ideal for stainless steel (304/316) and carbon steel.
Asymmetric Cutting Edges: Reduce torque by 25% when tapping 6mm-deep threads.
Through-Tool Coolant Channels: Direct lubricant to the cutting zone, critical for dry machining.
Performance Metrics
500+ Holes in 304 Stainless: Before regrinding (vs. 150 with conventional taps).
Thread Quality: Class 6H tolerance maintained over full tool life.
Speed: 1,200 RPM drilling / 600 RPM tapping in 12mm thick A36 steel.
Industrial Valve Manufacturing Success
A plant producing hydraulic valve bodies achieved:
40% Lower Tooling Costs: By combining two operations.
Ra 1.6µm Thread Finish: Eliminated secondary deburring.
Interrupted Cut Survival: 100% success rate on cross-drilled holes.
Technical Edge
Length of Drill(mm): 7.5mm (M4)
Coating: AlCrN for high-temperature stability
Compatibility: CNC mills, drill presses, and tapping arms
Transform your production line – where hardness meets efficiency.
