Engineered for precision metal threading, the OSG Metric Spiral Point Threading Tap in M33 x 3.5 is built for through-hole applications. Crafted from HSS-E with cobalt and finished in steam oxide, it delivers durable, heat-resistant performance in demanding machining environments.

• Tap type: Metric spiral-point threading tap designed for through-hole tapping, enabling efficient chip evacuation and clean, accurate threads.
• Size: M33 x 3.5 standard metric thread with through-hole compatibility.
• Material: High-Speed Steel with cobalt (HSS-E) for increased hardness and wear resistance.
• Coating: Steam oxide treatment to enhance surface durability and lubrication retention.
• Through-hole design: Specifically optimized for tapping internal threads in through-holes, reducing drift and improving thread quality.
• Precision performance: Designed for demanding threading operations, providing consistent thread pitch and flute geometry.

With its cobalt-infused HSS-E core and steam-oxide finish, this tap stands up to heat and wear, delivering reliable performance over extended tool life. The spiral-point geometry rapidly evacuates chips, minimizing clogging and ensuring smooth cutting action across through-holes. Users can expect cleaner threads, tighter tolerances, and reduced rework in applications that demand durable, high-precision tapping. Ideal for machine shops and production environments, this tap helps you complete challenging projects faster with consistent results.
