MANFROTTO TAP G 1/4 DIN-5156C R45 HSSE-PM HL MASTERTAP

In a busy machine shop, a machinist picks up the MANFROTTO MASTERTAP G 1/4 DIN-5156C R45 HSSE-PM helical flute tap to thread through holes in a stainless steel component. The tool's 45-degree helix angle pulls chips backward, preventing clogging and ensuring a clean, accurate thread. Made from powder metallurgy high-speed steel with cobalt, this tap withstands high cutting temperatures and maintains sharpness over many cycles. The bright finish reduces friction, and the cylindrical shank with square drive fits standard tap holders. With a tolerance class of C, it produces threads that meet DIN 5156 standards, making it a reliable choice for professional threading operations.

Key specifications

• Thread type: G (BSPP) 1/4 inch, 19 TPI
• Material: HSSE-PM (powder metallurgy high-speed steel with cobalt)
• Flute type: Helical, 45° helix angle, right-hand cutting
• Standard: DIN 5156, tolerance class C
• Overall length: 100 mm, thread length: 22 mm, shank diameter: 10 mm, square drive: 8 mm
• Surface treatment: Bright (uncoated)
• Application: Through holes in steel, stainless steel, cast iron, non-ferrous metals

Why choose it

The helical flute design excels in through-hole applications, efficiently evacuating chips and reducing the risk of tap breakage. Cobalt-enriched HSSE-PM offers superior hardness and heat resistance compared to standard HSS, extending tool life in demanding materials. The precise DIN 5156 geometry ensures consistent thread quality, while the bright finish minimizes friction for smoother cutting. This tap is part of the MASTERTAP line, known for high performance and reliability in industrial settings.

Ideal use cases

• Creating G 1/4 BSPP threads in through holes on steel and stainless steel workpieces
• Maintenance and repair operations requiring precise parallel pipe threads
• Production environments where consistent thread quality and tool longevity are critical
• Machining cast iron and non-ferrous metals with a single versatile tap

Good to know

The tap is designed for machine tapping with a suitable holder and cutting fluid. Always ensure proper alignment and speed for the workpiece material. The square drive size is 8 mm, compatible with standard tap wrenches and holders. Store in a dry environment to prevent corrosion of the bright surface.
