- Integrated Design: Features a dual-function design with a 118° drill point and a 60° thread angle, allowing for the drilling of holes and the creation of M3-M10 metric threads in a single operation. This efficiency reduces tool change time during repairs and extends the lifespan of machine protection systems on automotive brake calipers by 70%. - Advanced Surface Treatment: Coated with a durable TI nitride layer (2-3μm thickness) that provides a hardness of 2800 HV. This treatment significantly extends tool life by 2.5 times compared to standard HSS when working with zinc alloy (3-5mm thickness) and 6061 aluminum extrusions in CNC machining centers. - Precise Thread Geometry: The thread profile is ground to achieve a pitch accuracy of ±0.05 mm, ensuring clean threads with tolerances of 4H-6H in applications such as copper pipe joints and mild steel angles. A chamfer depth of 1.5-2.5 mm is included for secure fastener fixing in furniture assembly lines. - Material Compatibility: Constructed from an HSS substrate with a hardness of 62-64 HRC, this tool efficiently processes materials up to 150 BHN hardness, including plastic composites, soft iron plates, and brass electrical components. Note that hardened steels are excluded as per product specifications. Use Scenarios: 1. Ideal for automotive repair shops needing to quickly drill and tap threads in brake calipers without changing tools. 2. Perfect for CNC machining centers working with aluminum extrusions and zinc alloys, maximizing productivity and tool lifespan. 3. Essential for furniture manufacturers wanting reliable thread cutting and drilling capabilities for efficient assembly processes.
