Tap FANAR GWINTOWNIK M8 KOMBI‑D R30 (6H) HSS WIERTLO — M8 combined HSS tap with drill point

FANAR GWINTOWNIK M8 KOMBI‑D R30 (6H) HSS WIERTLO — M8 combined HSS tap with drill point is a single‑operation tool designed to drill and cut internal M8 threads. Manufactured from high‑speed steel (HSS) with the KOMBI‑D geometry, this tap integrates a drill point and a thread cutting section to reduce setup time and improve process efficiency for through and blind holes. The tool is produced to deliver a 6H tolerance class for internal threads and is intended for use in metalworking and maintenance environments where reliable thread quality is required.

Advantages

The combined drill‑tap design eliminates the need for a separate drilling operation, reducing cycle time and handling. HSS construction offers wear resistance and toughness suitable for a variety of common steels and non‑ferrous materials. The KOMBI‑D geometry optimizes chip formation and evacuation during threading, while the integrated drill point ensures accurate hole centering and consistent thread start. The 6H tolerance class provides standardised internal thread fit for compatible fasteners.

Suitable for

• Drilling and tapping M8 internal threads in a single operation
• Through holes and blind holes in metal components
• Maintenance, repair and assembly tasks requiring threaded holes
• Small batch machining and workshop work where setup reduction is beneficial

Key specifications

• Thread size: M8
• Material: high‑speed steel (HSS)
• Design: combined drill point and tap (KOMBI‑D)
• Tolerance class: 6H for internal threads
• Application: suitable for through and blind holes

How to use

Secure the workpiece and select appropriate feed and speed for the workpiece material based on HSS tooling recommendations. Use appropriate cutting fluid to improve chip evacuation and tool life when machining steels or alloys. Position the tap accurately and apply steady axial feed while allowing the integrated drill point to create the hole and the tap portion to cut threads. Reverse the rotation to break chips and withdraw the tool carefully once threading is complete.

Usage recommendations

For best results, match spindle speed and feed to the material being machined and use suitable cutting fluid. Inspect tool condition regularly and replace the tap when wear affects thread quality. When producing blind holes, monitor drill depth to avoid bottoming out; for harder materials consider pre‑drilling when recommended by tooling guidelines.
