Tap FANAR GWINTOWNIK M4 KOMBI-D R30 (6H) HSS with drill point

FANAR GWINTOWNIK M4 KOMBI-D R30 (6H) HSS with drill point is a combination M4 tap made from high-speed steel (HSS). The tool combines threading and drilling geometry in a single unit, allowing it to form internal metric M4 threads in through and blind holes. Designed for compatibility with standard tap holders and both manual and machine tapping, this tap supports general machining and workshop operations where reliable thread cutting and efficient chip evacuation are required.

Advantages

The HSS material provides good wear resistance and heat tolerance for general-purpose tapping. The drill-point geometry enables faster penetration and simplified alignment when starting holes, reducing the need for a separate pilot drill in many through-hole applications. The combination design improves chip flow and lowers the risk of tap breakage in moderate production and maintenance tasks. Its dimensions and shank are suitable for use with common tap holders and tapping fixtures.

Suitable for

• Cutting M4 internal metric threads in through holes
• Creating M4 threads in blind holes where a drill-point tap is appropriate
• General workshop maintenance and repair tasks
• Manual tapping with tap wrenches and machine tapping with appropriate holders

Key specifications

• Thread size: M4
• Tool material: high-speed steel (HSS)
• Tip style: drill point (combination/drill-tip)
• Tolerance/class: suitable for standard metric thread fit (6H)
• Flute/geometry: designed for chip evacuation in general-purpose use
• Application: suitable for through and blind holes depending on depth and material

How to use

Select the appropriate pilot hole diameter and prepare the workpiece using standard drilling practice if required. Secure the workpiece and align the tap with the hole axis. Apply suitable cutting fluid for the material being tapped. For manual tapping, use steady, controlled turns with periodic reversals to break chips. For machine tapping, use correct spindle speed and feed consistent with M4 HSS taps and ensure the tap holder is rigidly mounted. Back the tap out periodically to clear chips and inspect thread quality during the process.

Usage recommendations

Use appropriate cutting oil or lubricant for ferrous and non-ferrous materials, and avoid excessive feed or spindle speed to reduce wear. For hardened or abrasive materials, consider using specialized taps or coating options. Ensure proper chip evacuation and clamping to minimize risk of tap fracture. Replace the tap when wear or damage affects thread quality.
