RUKO HGB-DIN352-HSS-60°-N.º 12 Macho de roscar manual M12 x 1,75 mm DIN 352 HSS Blank

The RUKO HGB-DIN352-HSS-60°-Nr.12 is a precision hand tap for cutting metric coarse threads in unalloyed and low-alloyed steels, cast iron, and non-ferrous metals. Unlike machine taps that require a dedicated tapping machine, this single hand tap is designed for manual use with a tap wrench, giving you full control in repair and maintenance work. Manufactured from high-speed steel (HSS) with a bright finish, it offers a reliable balance of hardness and toughness for threading through holes.

Highlights

• Thread standard: DIN 352 for metric coarse threads
• Nominal diameter M12 with 1.75 mm pitch
• Right-hand cutting direction
• Three flutes for efficient chip evacuation
• Square drive size 7.0 mm for secure wrench engagement

In daily use

With a thread length of 29 mm and an overall length of 89 mm, this tap reaches deep enough for most through-hole applications while remaining compact. The 9.0 mm shank diameter fits standard tap wrenches, and the 7.0 mm square drive prevents slipping during manual threading. For a clean M12 thread, drill a core hole of 10.2 mm before tapping.
