The OSG Threading Tap Metric A-LT-Spiral Point is a right-hand tool built for precise through-hole threading with durability you can rely on in demanding production environments. Featuring a TiCN-coated, powder-metal body, it blends strength and low friction to maintain clean, accurate threads at higher speeds.
- Substrate: Powder-metal body delivers toughness and wear resistance for long tool life under high-speed threading.
- Coating: TiCN coating reduces friction and improves chip flow, enabling more consistent cuts and better heat handling.
- Threading Design: Spiral-point geometry directs chips forward, lowering the risk of clogging and producing clean, accurate threads.
- Hand: Right-hand (CW) threading for standard external threads in common manufacturing settings.
- Through-Hole Compatibility: Optimized for through-hole applications and aligned with DIN 376 standards for reliable hole threading.
- Size: Metric M20 x 2.5, designed to form robust threads in sizeable through-holes.
This tap’s combination of a hardened powder-metal substrate and TiCN coating translates into tangible advantages: extended tool life even under repetitive, high-speed cycles; steadier thread formation with minimal deviation; and smoother operation that reduces downtime caused by chip build-up. The spiral-point geometry further enhances efficiency by pushing chips ahead of the thread path, helping you achieve precise, repeatable threads in a range of materials across automotive, machinery, and industrial applications. For projects requiring dependable through-hole tapping with tight tolerances, the OSG Metric A-LT-Spiral Point tap delivers consistent performance from first cut to last.
