The OSG Threading Tap is a metric fine-thread tap engineered for clean, accurate threading in blind holes. It’s built for machinists and fabricators who demand dependable performance in tight spaces and demanding materials.

• Size and pitch: M16 x 1.5 metric fine thread for precise, compatible fasteners
• Thread direction: Right-hand threading for standard metalworking applications
• Flute design: A-Spiral flute for efficient chip evacuation in blind holes, reducing clogging
• Material: Powder-metal construction for improved wear resistance and extended tool life
• Coating: TiCN coating increases hardness and lowers friction at high speeds and temperatures
• Standards: DIN374 compatibility ensures consistent threading quality in production

This combination delivers crisp thread profiles with reduced risk of cross-threading and rework. The TiCN coating maintains performance under higher cutting speeds and temperatures, while the powder-metal core resists wear through repeated use. The A-Spiral flute design speeds chip clearance from blind holes, promoting smoother operation and longer service life in demanding tapping jobs.
