Description
OSG's Threading Tap is a metric A-Spiral Point threading tool designed for through-hole work, delivering precise M4 x 0.7 threads. Built on a right-hand HB Weldon powder-metal shank and TiCN-coated for durability, it excels where consistent performance matters.
- Metric A-Spiral Point design: Efficiently drives chips forward for clean, accurate threads in through-holes.
- HB Weldon powder-metal shank: Provides secure retention in standard tool holders, reducing slippage during use.
- TiCN coating: Reduces friction, enhances heat resistance, and extends tool life for repeated production runs.
- Right-hand threading: Optimized for common tapping motions and machine setups.
- Through-hole compatibility: Specifically engineered for through-hole DIN371/1835 applications to ensure reliable thread formation.
- DIN371/1835 standard: Aligns with widely used machine tools and accessories for seamless integration.
- Size and pitch: M4 x 0.7, suitable for standard metric thread configurations in lightweight to medium-duty tasks.
- Materials: Powder-metal substrate delivering a balance of toughness and wear resistance in demanding environments.
The A-Spiral Point geometry supports consistent chip evacuation, helping to prevent built-up material and ensuring smooth engagement of the new thread. The TiCN coating lowers friction at the cutting interface, enabling more stable feeds and better surface finish. The Weldon shank design enhances tool retention in clamping systems, which is especially beneficial during deeper taps or higher-t torque operations. Together, these attributes make this tap a dependable choice for producing precise M4 x 0.7 threads in through-hole components across a range of metalworking tasks—from prototyping to high-volume production.
