Description

The OSG Threading Tap is engineered for reliable metric blind-hole threading, delivering consistent, high-quality threads for precision assemblies. Designed for machinists who demand depth, durability, and efficient cutting, this TiCN-coated tap excels in demanding, high-speed operations.

  • Threading Tap Type: Metric A-Spiral Flute - Form E
  • Material: Powder Metal construction for high strength, wear resistance, and toughness
  • Coating: TiCN coating to increase surface hardness, reduce friction, and extend tool life
  • Flute Design: Right-hand spiral flute with extended Form E length for deeper blind-hole tapping and effective chip removal
  • Hole Type: Blind holes (DIN371) ensuring consistent thread fit and finish
  • Size: M5.5 x 0.9
  • Application: Suited for high-speed, demanding threading in metalworking environments

This combination of Form E flute length, spiral chip evacuation, and TiCN-coated powder-metal construction translates to fewer tool bits changes, lower risk of tap breakage in deep or obstructed holes, and longer tool life under tough cutting conditions. The tap maintains steady performance across standard blind-hole applications, delivering reliable threads that meet DIN371 tolerances without sacrificing speed or precision.
