Macho de rosca G 1/4 BSPP Manfrotto DIN 5156B HSSE-PM HL MASTERTAP

Cutting precise internal pipe threads in tough materials demands a tap that resists wear and maintains accuracy under pressure. The Manfrotto G 1/4 machine tap meets that challenge with a powder-metallurgy HSSE-PM substrate, cobalt enrichment, and an HL surface treatment for smooth chip evacuation and extended tool life. Engineered to DIN 5156B, it produces G 1/4 (BSPP) parallel threads with a 1.337 mm pitch, ideal for fluid and pneumatic connections where a reliable seal is critical.

Who is it for

This tap is built for machinists, maintenance technicians, and metalworking professionals who thread steel, stainless steel, cast iron, and non-ferrous alloys. It suits both CNC setups and manual tapping operations where consistent thread quality and dimensional accuracy are non-negotiable.

Tips

Use a suitable tapping fluid for the workpiece material to maximize tool life and thread quality. For blind holes, ensure adequate chip clearance and consider a spiral-flute tap if chip evacuation becomes problematic. Always align the tap perpendicular to the workpiece to avoid thread distortion.
