RUKO HGB set maschi a mano DIN 5157 HSS-G G 5/8 inch x 14 TPI, 2 pezzi

This RUKO hand tap set is configured for British Standard Pipe Parallel threads, providing a reliable solution for cutting G 5/8" x 14 TPI internal threads in a range of materials. The set includes both a taper tap and a plug tap, allowing you to progress from initial cutting to final sizing with precision.

Highlights

• Two-piece set: taper tap for starting threads, plug tap for finishing to full depth
• Ground HSS-G high-speed steel construction for durability and clean cutting
• Straight flute design suitable for through holes and blind holes with chip evacuation
• Right-hand cutting direction for standard threading operations
• Square shank for secure grip in tap wrenches

In daily use

The taps are made from ground high-speed steel, which maintains sharpness when threading unalloyed and low-alloy steels, malleable cast iron, non-ferrous metals, and plastics. The recommended core hole diameter is 21.0 mm, and the set is suitable for materials with tensile strength up to 800 N/mm². The bright finish reduces friction during cutting.
