16.5mm Countersink 75° HSS 3-Flute Cylindrical Shank, Right-Hand - TECWERK

Reliable, burr‑free countersinking is achieved by combining HSS construction, a 75° cone angle and three cutting edges for clean, repeatable results; order the TECWERK cone countersink directly via Metav Werkzeuge or consult the specialists if technical questions arise.

TECWERK Cone Countersink 75° Ø16.5 mm — HSS, 3 flutes, Ø10 mm shank

The TECWERK Cone Countersink 75° Ø16.5 mm is an HSS, three‑flute, right‑hand countersink designed for burr‑ and chatter‑free countersinking, deburring and chamfering in steel, cast iron and non‑ferrous alloys.

• High-speed steel (HSS) construction
• 75° cone angle for standard countersinks
• Three cutting edges for smooth finish
• 10 mm cylindrical shank for secure mounting

Consistent, burr‑free finishing for production work

The combination of HSS material and a 75° cone angle produces a controlled cutting geometry that reduces vibration and prevents chattering. With three flutes, the cutting load is distributed evenly, which yields a burr‑free edge and a smooth finish on the workpiece. This results in fewer rework cycles and a predictable surface quality when preparing holes for fasteners or preparing bearing seats. The tool’s geometry is optimised for repeatability in both single‑part production and serial machining.

Robust tool design for longer tool life and stable cuts

Constructed in high‑speed steel and executed in Form C geometry, the countersink is designed to tolerate interrupted cuts while maintaining edge strength. The right‑hand cutting geometry and balanced flute design reduce wear under moderate loads, making the tool suitable where a reliable lifecycle is required. Because the tool performs best at low cutting speed, tool life is extended and heat build‑up is minimised, which supports stable dimensional accuracy over longer production runs.

Clear operating guidance and material suitability

The tool is specified for a feed of 0.14 mm/rev in steel up to 500 N, which gives a practical reference point for setting feed rates to achieve the intended finish without overstressing the cutter. The design is suitable for machining steel, cast iron and non‑ferrous metals including aluminium and brass, as well as light alloys. The 10 mm shank ensures compatibility with common chucks and collets, allowing straightforward integration into existing tooling setups without special adaptors.

Practical benefits for workshop efficiency

A cylindrical shank and standard dimensions simplify handling and set‑up; secure clamping reduces run‑out and supports concentric countersinking. The tool’s ability to deliver clean chamfers and deburred hole edges decreases downstream finishing time and supports a more efficient workflow on the shop floor. When matched to appropriate spindle speeds and the advised feed, the cutter helps maintain part tolerances and reduces the need for manual deburring, saving operator time and reducing overall cycle variability.

FAQ

Is this countersink suitable for cast iron?
Yes. The TECWERK Cone Countersink 75° Ø16.5 mm is specified for use in cast iron as well as in steel and non‑ferrous metals, delivering clean countersinks when run at appropriate speeds.

What feed and speed achieve the best surface quality?
For steel, a feed of 0.14 mm/rev (at cutting forces up to 500 N) is recommended; the cutter gives its best finish at lower cutting speeds to limit heat and prolong edge life.

Will the 10 mm shank fit a standard drill chuck or collet?
The tool’s 10 mm shank is designed for secure clamping in common 10 mm chucks and collets, facilitating easy mounting in typical workshop and production spindles.

Does the tool reduce the need for manual deburring?
Yes. Thanks to the three‑flute geometry and optimised cone angle, the countersink produces a burr‑reduced finish that can significantly reduce manual deburring work.

Is the countersink suitable for aluminium and other light alloys?
Yes. The cutter is specified for non‑ferrous and light metals such as aluminium and brass, where its geometry helps avoid tearing and ensures a clean chamfer.
