RUKO HGB Set DIN 352 HSS 60° M5 x 0.8 Taps, 3-Piece Set

For machinists and metalworkers who need to cut clean internal threads in steel or cast iron, the RUKO HGB Set DIN 352 HSS 60° No. 5x provides a complete 3-piece hand tap set for M5 threads. Each tap is made from bright high-speed steel and ground to a 60° thread flank angle, following DIN 352. The set includes a taper tap, a second tap, and a bottoming tap, allowing you to start, deepen, and finish threads in through or blind holes. The square drive shank fits standard tap wrenches, and the set comes in a plastic box for organized storage.

Why choose it

The set covers the full tapping sequence, so you can produce accurate threads without buying individual taps. HSS construction withstands the heat and abrasion of manual tapping in tough materials, while the bright finish reduces friction. The DIN 352 geometry ensures compatibility with standard drill sizes and tap wrenches.

Ideal use cases

• Creating M5 threads in steel plates, brackets, and machine parts
• Repairing damaged threads in cast iron housings
• Maintenance and prototyping in workshops and on-site

Good to know

For blind holes, use the taper tap first, then the second tap, and finish with the bottoming tap to get full threads close to the bottom. Use a suitable cutting fluid for best results and longer tool life.
