RUKO HGB-DIN352-HSSCo-60°-M-3x0,50mm 3-Piece HSS-Co Machine Tap Set, Metric M3 x 0.50 mm, DIN 352, Right-Hand, Bright Finish

Cutting precise M3 threads by hand or machine often leads to broken taps, poor finish, or misaligned threads when working with tough materials. This RUKO 3-piece tap set solves that problem by providing a dedicated taper, second, and finishing tap made from cobalt-alloyed high-speed steel, so each cut is clean, controlled, and accurate.

Who is it for

Machinists, metalworkers, and maintenance technicians who need reliable internal threading in steel, cast iron, non-ferrous metals, or plastics. The set is ideal for both through and blind holes where thread quality and tool life matter.

Main features

• Three-piece set: taper, second, and finish taps for progressive thread cutting.
• HSS-Co material withstands higher temperatures and wear than standard HSS.
• DIN 352 geometry with 60° thread angle and ISO 2 (6H) tolerance.
• Right-hand cutting direction with square drive shank for secure tool holding.
• Bright surface treatment reduces friction and improves chip flow.

Tips

Use cutting oil suitable for the workpiece material to extend tap life and improve thread finish. For blind holes, start with the taper tap, then switch to the second and finish taps to achieve full thread depth without bottoming damage.
