Thread tap M20 x 1.5 HSS hand tap DIN 22568 (6g) — No name

Hand thread tap for producing or repairing internal metric threads M20 × 1.5 made from high-speed steel (HSS). The tool is manufactured to conform with DIN 22568 and provides 6g tolerance for standard metric internal threads. It is suitable for manual tapping operations with a tap wrench and can also be used in guided machine setups where hand taps are applicable. The compact design makes it practical for maintenance, repair and small-series production tasks in metalworking.

Advantages

The HSS material offers good hardness and wear resistance for cutting steel and non-ferrous metals at typical hand-tapping speeds. Compliance with DIN 22568 and tolerance class 6g ensures interchangeability with standard metric bolts and components. The tap's geometry is optimized for general-purpose threading, balancing cutting performance and tool life. Its robust shank and flute design enable reliable chip evacuation in many common tapping situations.

Suitable for

• Cutting new internal metric threads M20 × 1.5 in steel and non-ferrous metals
• Repairing damaged or worn M20 × 1.5 internal threads
• Manual tapping with a tap wrench in maintenance and field service
• Use in guided machine tapping setups where hand-style taps are applicable

Key specifications

• Thread size and pitch: M20 × 1.5
• Material: high-speed steel (HSS)
• Tolerance class: 6g (metric internal thread tolerance)
• Standard: manufactured to DIN 22568
• Application type: hand tap (suitable for manual and compatible machine use)

How to use

Secure the workpiece and drill the correct pilot hole diameter for an M20 × 1.5 internal thread before tapping. Apply suitable cutting fluid to the tap and workpiece to reduce friction and assist chip evacuation. Start the tap square to the hole and turn it forward with a tap wrench, advancing gradually and reversing periodically to break chips. For deeper threads, clear chips frequently and reapply lubricant. When finished, remove the tap carefully and clean the thread and tap.

Usage recommendations

Use cutting oil appropriate for the workpiece material and avoid excessive axial force during manual tapping. For damaged threads, inspect the hole and consider using an undersized pilot or multiple passes. Store the tap in a dry place and protect the cutting edges from impact to preserve tool life.
