RUKO HGB-DIN352-HSSCo-60°-M-5x0,80mm Hand Tap, Metric Coarse, M5 x 0.80 mm, DIN 352, HSS-Co

When threading M5 holes in steel components on the bench or in the workshop, this RUKO hand tap cuts clean, accurate threads in unalloyed and alloyed steels up to 800 N/mm². The HSS-Co material withstands the heat of manual tapping, while the DIN 352 geometry with 60° thread angle and 3 flutes ensures smooth chip evacuation in through and blind holes.

Key specifications

• Thread type: Metric Coarse
• Nominal diameter: M5
• Thread pitch: 0.80 mm
• Standard: DIN 352
• Material: HSS-Co (High-Speed Steel with Cobalt)
• Tolerance class: ISO 2 (6H)
• Cutting direction: Right-hand
• Overall length (L1): 70 mm
• Thread length (L2): 16 mm
• Shank diameter (d2): 4.5 mm

Why choose it

HSS-Co provides higher wear resistance than standard HSS, extending tool life when tapping abrasive steels. The right-hand cutting direction suits standard clockwise threading, and the ISO 2 (6H) tolerance produces threads compatible with common metric fasteners.

Ideal use cases

• Creating M5 threads in steel plates, brackets, and machine parts
• Repairing damaged threads in existing components
• Prototyping and small-batch production in metalworking shops

Good to know

For blind holes, drill to the recommended core hole diameter of 4.2 mm and ensure adequate depth for the 16 mm thread length. Use a suitable tap wrench on the 3.4 mm square drive.
