RUKO HGB conjunto de machos manuais DIN 2181 M16 x 1,25 mm rosca fina métrica, 2 peças HSS

Cutting precise metric fine threads in tough materials demands a tap set that stays sharp and accurate. The RUKO HGB Hand Tap Set DIN 2181 M16 x 1.25 mm delivers two high-speed steel taps—a taper tap for starting and a bottoming tap for finishing—so you can thread through holes and blind holes in steel, cast iron, non-ferrous metals, and plastics without tool failure.

Who is it for

Machinists, metalworkers, and maintenance technicians who need reliable hand tapping in workshops or on-site. It suits anyone working with materials up to 800 N/mm² tensile strength, where a standard tap set might dull or break.

Main features

• Set includes 2 taps: taper tap (Vorschneider) and bottoming tap (Fertigschneider) for complete thread cutting.
• Metric fine thread M16 x 1.25 mm to DIN 2181 standard.
• High-speed steel (HSS) construction for durability and heat resistance.
• Right-hand cutting direction with ISO 2 (6H) thread tolerance.
• Recommended core hole diameter 14.75 mm for accurate tapping.
• Bright, uncoated surface finish for clean cuts.
• Square shank (DIN 10) for secure holding in tap wrenches.

Tips

Use cutting oil when tapping metals to extend tool life and improve thread finish. For blind holes, start with the taper tap, then finish with the bottoming tap to get full threads close to the bottom. Always drill the core hole to 14.75 mm for M16 x 1.25 mm threads.
