Precision threading tap built for metric blind-hole work, crafted to deliver reliable, high-precision tapping in demanding metalwork. The OSG A-Spiral Flute design, TiCN coating, and HB Weldon shank combine to optimize chip evacuation, wear resistance, and stability in tight blind holes.

• Flute geometry: A-Spiral flute promotes efficient chip evacuation in blind holes, helping to reduce chip clogging and deliver smoother tapping in restricted depths.
• Material and coating: Powder-metal substrate with a TiCN coating provides enhanced wear resistance and reduced friction for longer tool life.
• Shank type: HB Weldon shank delivers added stability and alignment in collets and chucks for consistent performance.
• Size and standard: Metric size M12 x 1.75, designed for tapping metric blind holes; conforms to DIN371/1835 specifications for reliable interchangeability.
• Handedness: Right-hand threading, suitable for standard tapping operations in common metalworking applications.

This combination supports clean, accurate thread formation in blind-hole applications, with improved tool life and predictable results. The TiCN-coated, powder-metal construction reduces wear and friction, while the Weldon shank ensures steady, repeatable taps even under higher cutting speeds and longer cycles. Ideal for precision machining tasks where consistent thread quality and durability matter.
