RUKO HGB Conjunto de 2 machos de roscar manuais DIN 2181 rosca métrica fina M8 x 1,0 mm HSS-G

Cutting precise M8 fine threads by hand in steel and cast iron is a challenge when taps are dull or poorly matched to the material. This RUKO two-piece hand tap set solves that with ground HSS-G taps made to DIN 2181, giving you a reliable thread in through and blind holes.

Who is it for

Machinists, metalworkers, and maintenance technicians who need to cut metric fine threads with a pitch of 1.0 mm in unalloyed and low-alloy steels, cast iron, and non-ferrous metals up to 800 N/mm² tensile strength.

Main features

• Two-piece set: taper tap for starting and bottoming tap for finishing threads to the bottom of blind holes.
• Metric fine thread M8 x 1.0 mm to DIN 2181, tolerance class ISO 2 (6H).
• Made from HSS-G (high-speed steel, ground) for durability and clean cutting.
• Right-hand cutting direction with square drive shank for standard tap wrenches.
• Recommended core hole diameter: 7.0 mm.
