RUKO HGB-DIN2181-HSS-60°-MF-6x0.75mm Machine Tap

Precision-ground machine tap for metric fine threads, engineered for reliable thread cutting in through and blind holes. The 60° flank angle and ISO 2 (6H) tolerance ensure accurate threads in unalloyed and alloyed steels up to 900 N/mm², cast iron, and non-ferrous metals. Unlike hand taps, this machine tap is optimized for use in drill presses and CNC machines, with a Form C lead (2-3 threads) for easy starting and three flutes for efficient chip evacuation.

Highlights

• Metric fine thread M6 x 0.75 per DIN 2181
• High-speed steel (HSS) with bright finish for durability
• Right-hand cutting direction with 3 flutes
• Form C point geometry for through and blind holes
• Recommended cooling lubricant for extended tool life

In daily use

Mount the tap in a suitable machine chuck or tap holder, apply cutting fluid, and set the spindle speed appropriate for the workpiece material. The tap's square drive (4.9 mm) provides secure torque transmission, while the 18 mm thread length covers common thread depths. After tapping, reverse the spindle to retract the tap without damaging the threads.
