TECWERK 120° Countersink Ø 8.3 mm — HSS, 3‑flute, 6 mm shank

A TECWERK 120° countersink engineered for clean chamfering, deburring and flush countersinking in steel, cast and light metals.

• HSS construction, Form C, 3 flutes
• 120° countersink angle
• 6 mm cylindrical shank
• Burr-free chamfering in mixed metals

Faster production with burr‑free results

The high-speed steel construction combined with a 120° countersink geometry and 3-flute design delivers clean chamfers with reduced burr formation, which directly lowers rework rates and inspection time. In practice, this geometry spreads cutting forces over three edges to reduce vibration and tool deflection, producing a burr-free seat for fasteners and plated finishes. The right-hand cutting action supports conventional machining setups, making the tool suitable for both manual and CNC countersinking operations in standard workshop environments.

Reliable performance across common workshop materials

Designed for mixed-material use, the tool is suitable for steel, cast iron and a range of non‑ferrous metals and light alloys. The tool’s geometry produces best results at lower cutting speeds, which helps protect edge life when machining tougher substrates. For higher cutting forces, the manufacturer specifies a reference feed of 0.09 mm/rev in steel up to 500 N; following this guideline helps to maintain consistent edge engagement and avoids chatter, improving surface finish and reducing the risk of workpiece damage during countersinking operations.

Secure clamping and consistent handling

A 6 mm shank with cylindrical profile ensures secure clamping in standard collets and bit holders, while the Form C contour and balanced flute distribution support smooth chip evacuation and a stable cut. The combination of three cutting edges and the specified feed characteristics promotes longevity and predictable tool life, making the countersink suitable for repeatable production tasks. Supplied as a single unit, the tool is compact and straightforward to integrate into existing tooling arrays for assembly preparation and finishing operations.

FAQ

Which materials can this countersink machine effectively work with?
The tool is designed for steel, cast iron and a variety of non‑ferrous and light metals; the TECWERK 120° countersink performs particularly well when used at lower cutting speeds to preserve edge life.

What clamping system is required for safe operation?
A standard 6 mm cylindrical collet or holder is suitable; the 6 mm shank provides stable clamping for reliable, repeatable results with the TECWERK countersink (SKU 2000865139NW).

What feed rate should be used for steel applications?
Use the reference feed of 0.09 mm/rev in steel under loads up to 500 N to achieve optimal surface finish and tool life with this countersink.

How does the 3‑flute design affect finish and tool life?
The three cutting edges distribute forces and reduce vibration, improving finish quality and extending edge life compared with fewer-flute variants.
