TECWERK Cross‑Hole Countersink 2–5 mm, 90° HSS‑Co

The TECWERK Cross‑Hole Countersink 2–5 mm is a precision 90° countersink with a cylindrical shank, designed for burr‑free chamfering and deburring across a range of ferrous and non‑ferrous materials

• HSS‑Co cutting material for long life
• 90° geometry for standard chamfering
• Cylindrical 6 mm shank for secure clamping

Reliable, burr‑free chamfering for production environments

The combination of HSS‑Co cutting material and a 90° tip angle delivers consistent chamfer quality and extended tool life. The tool’s peeling cut action shears rather than tears the material, which reduces burr formation and minimises the need for secondary deburring operations. Built with a chip evacuation path through the drill hole, the design prevents chips from jamming against the workpiece, ensuring steady performance even in interrupted cuts. With a 6 mm shank and 45 mm overall length, the countersink fits standard holders and maintains concentricity for accurate, repeatable chamfers. Recommended feed in steel (up to 500 N) is 0.07 mm/rev, which balances surface finish and tool longevity.

Versatile use across common workshop materials with lower cutting speeds

Engineered for use on steel, cast iron and non‑ferrous metals, this countersink is suitable for routine chamfering and light deburring tasks in both maintenance and production settings. Best results are achieved at low cutting speed, where the HSS‑Co grade retains hardness and resists thermal softening. The tool’s geometry is optimised for light to medium feeds and produces clean, chatter‑free chamfers that improve assembly fit and reduce inspection rework. For operations where surface quality and edge control matter, the controlled shearing action contributes directly to process efficiency and reduced downstream labour costs.

Simple integration, dependable handling and predictable results

Designed for straightforward integration into existing tool setups, the countersink’s 6 mm shank provides stable clamping and reduced runout in compatible chucks and collets. The compact overall length keeps the centre of gravity close to the holder for improved stability, important in serial production and automated setups. Constructed from HSS‑Co, the tool resists wear in abrasive conditions and offers a predictable tool life when operated within the recommended speed and feed window. Regular cleaning of the hole for chip escape and adherence to the specified feed rate maintain performance and help protect component edges, offering long‑term savings through fewer rejects and less rework.

FAQ

What size hole range is this countersink intended for?
The TECWERK cross‑hole countersink is specified for holes in the 2–5 mm range and is designed to produce clean 90° chamfers in that diameter band.

Can this countersink be used on hardened steel?
This countersink is made from HSS‑Co and is optimised for steels, cast iron and non‑ferrous metals; for hardened steels above the tool’s recommended hardness, a specialist indexable or coated solution should be considered.

How does the chip evacuation feature help in practice?
Chip evacuation through the cross hole prevents chips from jamming between tool and workpiece, which keeps the cutting edge clear and helps achieve the burr‑reduced chamfers described in the technical data.

What feed and speed settings are recommended for steel?
For steel up to 500 N the recommended feed is 0.07 mm/rev; pair this feed with a low cutting speed to maintain tool life and surface quality with the HSS‑Co grade.
