TECWERK 75° Countersink Ø6.3 mm HSS (3‑flute, 5 mm shank)

The TECWERK 75° Countersink Ø6.3 mm HSS is a precision cutting tool for burr-free countersinking, deburring and recessing in steel, cast iron and non-ferrous metals

• High-speed steel construction
• 75° angle for precision seating
• 3‑flute geometry for smooth cuts
• 5 mm cylindrical shank for secure grip

Consistent, burr-free finishing for mixed materials

The conical countersink delivers reproducible deburring and recessing results thanks to its Form C geometry and right-hand cutting design. Made from HSS, the tool maintains edge integrity during conventional machining and is especially effective when used at a low cutting speed. The Ø6.3 mm cutting diameter combined with a 75° countersink angle creates clean chamfers and reliable screw seating across steel, cast iron and a wide range of non-ferrous and light metals, reducing the need for secondary manual deburring and improving process throughput.

Geometry and feed control for reduced chatter and better surface quality

The 3‑flute configuration evens out cutting forces and reduces vibration, which leads to a burr-free finish and less tendency to chatter on interrupted cuts. With a recommended feed in steel up to 0.09 mm/rev, the tool supports stable material removal under moderate loads. The 5 mm cylindrical shank ensures a concentric mounting in common drill chucks and tool holders, helping to preserve hole quality and minimise run-out. These design choices support repeatable results and lower scrap rates in production and repair workshops.

Workflow benefits: efficiency and simple integration

Designed for straightforward integration into workshop operations, the countersink performs best at moderate spindle speeds and can be used as a hand-tool or in light-duty machine setups. The combination of HSS cutting edges and the Form C profile offers a balance between longevity and sharpness, so less frequent regrinding is required compared with softer geometries. As a compact tool with a standard 5 mm shank, it fits existing tooling inventory without special adaptors, simplifying tool management and reducing changeover time.

Practical considerations and application hints

For optimal lifetime and finish, select a reduced cutting speed when working tougher grades of steel and consider light cutting fluid application for heat control. The tool is right-hand cutting and suited to countersinking, deburring and recessing operations; it achieves best results on continuous feeds rather than aggressive plunge cycles. The modest size and robust geometry make it a reliable choice for maintenance, prototyping and serial workshop use where a predictable chamfer quality is required.

FAQ

What materials can this countersink machine for?
The countersink is suitable for steel, cast iron, non-ferrous and light metals; the TECWERK 75° Countersink Ø6.3 mm HSS achieves the best finish at reduced cutting speeds.

What feed and speed settings are recommended?
A feed of up to 0.09 mm/rev in steel is indicated; best results occur at lower spindle speeds combined with steady feed to avoid chatter.

Is the shank compatible with standard tool holders?
Yes, the 5 mm cylindrical shank fits standard chucks and light-duty tool holders for quick tool changes.

How does the 3‑flute design affect surface quality?
The 3‑flute geometry balances cutting forces, reducing vibration and delivering a burr-free surface with improved edge integrity.

Can the tool be reground or resharpened?
The HSS material and Form C profile allow for resharpening; regrinding practices should preserve the original 75° angle and flute geometry for consistent performance.
