The OSG Threading Tap is a metric M1 x 0.25 tap with an A-Spiral flute, engineered specifically for blind-hole threading. Built from durable powder metal and TiCN coated, it delivers reliable performance in a range of materials and high-speed production environments.

• Size / Thread: M1 x 0.25 metric tapping size for small-diameter blind-hole work.
• A-Spiral Flute Design: Optimized for chip evacuation in deep or blind holes, reducing clogging and heat buildup.
• Material: Powder metal body offering high strength and wear resistance for repeated use.
• Coating: TiCN coating increases hardness and lowers friction, extending tool life in demanding applications.
• Thread Direction: Right-hand threading aligned with standard tapping practices.
• Application: Specifically suited for blind holes and designed to meet DIN371 threading standards for compatibility.

In practice, this tap delivers consistent, accurate threads in tight cavities by combining a robust powder-metal core with a wear-resistant TiCN coating and an efficient A-Spiral flute. Ideal for precision assemblies where reliability and tool life matter—such as electronics housings, small automotive components, or any project requiring clean, defect-free internal threads in blind holes. Expect smoother chip evacuation, reduced cycle times, and longer tool life compared with uncoated or non-spiral designs, helping you maintain stable production and tighter tolerances across shifts.
