RUKO HGB set 2-delig DIN 2181 metrisch fijndraad handtapset M13 x 1,5 mm HSS-E

For machinists and maintenance technicians cutting M13 x 1.5 metric fine threads in steel, cast iron, or non-ferrous metals, this two-piece hand tap set from RUKO provides the essential taper and bottoming taps in one package. The taps are made from high-speed steel with cobalt (HSS-E) for durability and are manufactured to DIN 2181 with an ISO 2 (6H) tolerance class.

Key specifications

• Thread size: M13 x 1.5 mm (metric fine)
• Set includes: taper tap and bottoming tap
• Material: HSS-E (high-speed steel with cobalt)
• Standard: DIN 2181
• Tolerance: ISO 2 (6H)
• Total length: 90 mm
• Thread length: 28 mm
• Shank diameter: 10 mm
• Square drive: 8 mm
• Cutting direction: right-hand
• Surface: bright (uncoated)

Why choose it

The two-piece set covers both starting and finishing operations. The taper tap begins the thread with a gradual lead, while the bottoming tap cuts full threads to the bottom of blind holes. Cobalt alloyed HSS-E offers better heat resistance and wear life than standard HSS, especially in tougher steels up to 800 N/mm².

Ideal use cases

• Creating M13 x 1.5 internal threads in through holes
• Tapping blind holes where full thread depth is required near the bottom
• Maintenance and repair work on machinery and components
• Suitable for unalloyed and alloyed steels, cast iron, and non-ferrous metals

Good to know

The taps are uncoated (bright finish), which is typical for general-purpose hand tapping. Use a suitable tap wrench with an 8 mm square drive. Always use cutting oil appropriate for the workpiece material.
