Description

BEYOND Coated BSP(G) Spiral Groove Thread Tap for Aluminum

The BEYOND Coated BSP(G) Spiral Groove Thread Tap is engineered for high-efficiency threading of British Standard Pipe (BSP/G) threads in aluminum, copper, and other non-ferrous metals. Featuring a precision-ground spiral groove and advanced aluminum-specific coating, it ensures superior cutting performance, long tool life, and smooth chip evacuation even at high speeds.

Key Features

  • Conforms to BS 2779:1956 British Standard BSP(G) thread form (55° angle).
  • Special spiral flute geometry ideal for blind-hole threading in soft metals.
  • Aluminum-optimized coating for reduced friction and built-up edge prevention.
  • High-speed and stable cutting performance with excellent chip evacuation.
  • Available in BSP(G) thread sizes from 1/16” to 2 1/2”.

Applications

  • Designed for aluminum and non-ferrous metals (copper, brass, etc.).
  • Ideal for machining BSP and BSP(G) internal threads in fittings, hydraulic and pneumatic components.
  • Suitable for CNC machining centers, tapping machines, and lathes.

Material & Coating

  • Material: Ultra-fine grain carbide or high-speed steel (HSS-E).
  • Coating: DLC (Diamond-Like Carbon) or TiB₂ for aluminum — reduces adhesion and heat buildup.
  • Finish: Mirror-polished for smooth chip evacuation.

Advantages of BEYOND Aluminum BSP(G) Tap

  • High-speed cutting and minimal built-up edge on aluminum.
  • Improved surface finish and precision thread geometry.
  • Long tool life and consistent thread quality.
  • Optimized for both dry and lubricated machining.
