RUKO HGB DIN 352 HSS 60° M3 x 0,50 mm handtap

Creating precise internal threads in small components often requires a reliable tool that can handle tight tolerances without breaking. This RUKO hand tap solves that problem by providing a durable, accurately ground cutting edge for threading M3 holes with a 0.50 mm pitch.

Who is it for

Machinists, metalworkers, and maintenance technicians who need to cut or chase metric threads in steel, non-ferrous metals, or plastics. It suits both manual and light machine tapping operations where a plug tap is required.

Main features

• Metric ISO thread M3 with 0.50 mm pitch, manufactured to DIN 352.
• High-speed steel (HSS) construction for wear resistance and long tool life.
• 60° thread flank angle for standard metric thread form.
• Right-hand cutting direction with plug tap geometry.
• Square drive shank for secure holding in tap wrenches.
• Bright uncoated finish reduces friction and allows easy chip evacuation.

Tips

Use a suitable cutting fluid when tapping steel to improve thread finish and extend tool life. For blind holes, clear chips frequently to avoid clogging. Always start the tap square to the hole to prevent thread misalignment.
