The OSG Threading Tap Metric A-Spiral Point is a precision tool designed for through-hole threading in metalwork. Engineered for reliability and accuracy, it delivers consistent M4 x 0.7 threads with a +0.1 mm tolerance for a precise hole fit.

• Size & Thread: M4 x 0.7 metric, right-hand thread for standard through-hole applications
• A-Spiral Point Design: Promotes forward chip evacuation and clean, accurate threads in through-holes
• Material: Powder metal construction offers high wear resistance and improved heat tolerance for longer tool life
• Coating: TiCN coating reduces friction, enabling smoother cutting and faster cycle times
• Through-Hole Compatibility: DIN371 specification ensures compatibility with common through-hole threading standards
• Tolerance: +0.1 mm tolerance enhances hole-fit precision for mating fasteners

With this tap, you’ll maintain dimensional accuracy across production runs while reducing tool wear and rework. The combination of TiCN coating and powder-metal substrate supports higher cutting speeds and sustained performance in challenging materials. Its spiral point design minimizes chip buildup, delivering smooth, high-quality threads in a variety of metals, making it ideal for precision assemblies and reliable, repeatable results.
