OSG’s Metric A-LT-Spiral Point Tap is designed for precise, durable through-hole threading. Built for machinists and engineering shops that demand reliability, it combines powder-metal strength with a TiCN coating to deliver fast, clean threads with long tool life.

• Threading format: Right-hand metric threads with a spiral point for efficient chip evacuation and clean thread formation.
• Material: Powder-metal construction provides exceptional strength, wear resistance, and heat tolerance for challenging materials and higher-speed operations.
• Coating: TiCN coating reduces friction, enhances chip flow, and supports higher cutting speeds with smoother performance.
• Size and standard: M4 x 0.7 with through-hole compatibility, aligned to DIN371 threading standards.
• Through-hole design: Optimized for through-hole applications, promoting reliable tapping in through-holes with consistent thread quality.

With its spiral-point geometry and durable build, this tap helps push chips away from the cut, minimizing clogging and delivering precise, repeatable threads. The combination of a TiCN coating and powder-metal substrate extends tool life, reducing downtime and maintenance costs. Suitable for production runs and repair tasks alike, it offers dependable performance across a range of materials while maintaining tight tolerances and a smooth thread finish.
