The OSG Threading Tap is a precision tool built for through-hole work, delivering reliable, accurate M4 x 0.5 threads with every cut. Designed for machinists and engineers who demand consistency, it combines durability and high-precision performance in a compact tapping solution.

• Thread Type: Metric Fine A-Spiral Point, right-hand
• Material: Powder metal construction for improved wear resistance
• Coating: TiCN coating to reduce friction and extend tool life
• Size: M4 x 0.5
• Through-Hole Ready: Optimized for through-hole DIN371 applications
• Chip Handling: Spiral point design pushes chips forward for clean, efficient tapping
• Performance: Suitable for high-speed, high-precision threading across a range of materials
• Standard: Conforms to DIN371 for reliable interchangeability

With a TiCN-coated, powder-metal body, this tap offers enhanced durability and heat resistance, helping you achieve consistent thread quality while reducing tool wear. The spiral point geometry improves chip evacuation, minimizing chatter and end-of-cut burrs—ideal for tight-diameter through-holes and demanding production environments. Built for speed without sacrificing accuracy, it’s a dependable choice for precision tapping in modern machining workflows.
