RUKO käsikierretappi HGB-DIN352-HSS-60°-3/4

For machinists and maintenance technicians threading pipe fittings and hydraulic components, the RUKO hand tap HGB-DIN352-HSS-60°-3/4 cuts precise G 3/4" parallel threads in unalloyed and low-alloy steels, cast iron, and non-ferrous metals. Manufactured from high-speed steel with a bright finish, this straight-flute tap follows DIN 352 and features a 55° thread angle with 14 threads per inch. The tap measures 110 mm in total length with a 36 mm thread length, 18 mm shank diameter, and 14.5 mm square drive for secure tool holding. Right-hand cutting direction suits standard threading operations.

Why choose it

High-speed steel construction delivers durability and wear resistance for repeated threading tasks. The straight flute design efficiently evacuates chips, while the bright finish reduces friction and improves cutting performance. Conforming to DIN 352 ensures compatibility with standard tap wrenches and holders.

Ideal use cases

• Cutting internal G 3/4" parallel threads in pipe fittings and flanges
• Repairing or rethreading damaged threads in hydraulic and pneumatic components
• Creating threaded holes in steel, cast iron, and non-ferrous metal workpieces
• Maintenance and repair workshops, plumbing, and general engineering

Good to know

For optimal results, use a suitable cutting fluid and ensure the core hole is drilled to approximately 25.25 mm. The tap is designed for manual operation with a tap wrench; do not use with power tools unless appropriate torque control is available.
