Thread Tap FANAR GWINTOWNIK M6 KOMBI-D R30 (6H) HSS WIERTLO

FANAR GWINTOWNIK M6 KOMBI-D R30 (6H) HSS WIERTLO is a combined M6 thread tap made from high-speed steel (HSS) engineered for cutting or repairing internal metric threads with a 6H tolerance. The tool integrates a drill point for efficient through-hole tapping and uses R30 geometry to balance cutting performance and chip evacuation. It is intended for workshop and industrial applications and is suitable for use on steel and similar materials where reliable M6 internal threads are required.

Advantages

The combined design with an integrated drill point reduces setup time by allowing drilling and tapping in a single operation for through-holes. Manufactured from high-speed steel, the tap provides good wear resistance and maintains cutting performance under typical machining conditions. The R30 geometry promotes controlled chip formation and evacuation, helping to reduce the risk of thread damage during cutting. The 6H tolerance produces accurate, standard-compliant internal threads suitable for common fastening applications.

Suitable for

• Drilling and tapping through-holes to M6 internal threads
• Repairing damaged or worn M6 threads in steel components
• Workshop and production environments requiring fast setup and repeatability
• Applications on steel and comparable ferrous materials

Key specifications

• Thread size: M6 internal metric thread
• Tolerance class: 6H
• Material: high-speed steel (HSS)
• Tool type: combined drill-and-tap (KOMBI-D) with integrated drill point
• Geometry: R30 for chip control and cutting stability
• Intended hole type: through-holes

How to use

Select an appropriate drill speed and cutting fluid for the workpiece material, and secure the workpiece to prevent movement. Use the tap in a machine or hand tap holder designed for combined drill-and-tap tools, aligning the drill point with the hole center. Perform drilling and tapping in a single pass for through-holes, applying consistent feed and avoiding excessive torque. Retract periodically if necessary to clear chips, and finish by backing off the tap slightly to break chips and prevent thread damage. Clean the newly cut threads and inspect for conformity to required dimensions and fit.

Usage recommendations

For best results on steel and similar materials, use appropriate cutting fluid and moderate spindle speeds; inspect the tool regularly for wear and replace when cutting performance degrades. When repairing threads, verify thread condition and clearances before tapping to avoid further damage.
