RUKO HGB-DIN352-HSS-55° Hand Tap M10 x 1.5 mm DIN 352 HSS Bright Finishing Tap

The RUKO HGB-DIN352-HSS-55° is a precision hand tap for cutting metric ISO threads to DIN 352. Its 55° helix angle and three straight flutes deliver clean, accurate threads in through and blind holes, while the bright HSS finish ensures durability across steel, cast iron, non-ferrous metals and plastics.

Highlights

• Metric ISO thread M10 × 1.5 mm to DIN 352, tolerance class 6H
• High-speed steel (HSS) with bright finish for long tool life
• Three straight flutes and 55° helix angle for efficient chip evacuation
• Square drive shank fits standard tap wrenches and low-speed machines
• Recommended core hole diameter: 8.5 mm

In daily use

This finishing tap produces final threads with a precise 6H fit. Use it after a taper or plug tap, or directly for shallow blind holes. The square drive prevents slipping in the wrench, and the bright surface reduces friction for smoother cutting.
