Through‑hole countersink 15–20 mm 90° HSS‑Co TECWERK

A through‑hole countersink 15–20 mm 90° HSS‑Co designed for burr‑free chamfering and deburring across steel, cast iron and non‑ferrous metals

• HSS‑Co cutting material
• 90° countersink angle
• Cylindrical shank Ø12 mm
• Chip evacuation through the hole

Reliable, burr‑free chamfering for mixed materials

The countersink is manufactured from HSS‑Co, a high‑performance cobalt high‑speed steel that sustains cutting edges under heat and stress; this results in consistent chamfer quality when working with steel, cast iron and non‑ferrous alloys. The tool’s 90° countersink angle produces clean, standard chamfers suitable for fastener seating and visual finishing, while the described shearing cut reduces the formation of burrs and minimises secondary operations. For production settings, this translates into fewer rejects and lower rework rates.

Designed to prevent clogging and machining chatter

A distinctive feature is the through‑hole design that channels chips through the drilled hole, avoiding accumulation at the cutting edge and preventing the tool from jamming against the workpiece. This effective chip evacuation reduces the risk of chatter and irregular finishes, delivering smoother deburring cycles even at interrupted cuts. The tool is described as offering best results at low cutting speed, which stabilises process forces and further improves surface finish and repeatability.

Precision dimensions for consistent tool handling

The countersink comes with a cylindrical shank of 12 mm and an overall length of 85 mm, providing secure clamping in standard chucks and holders for repeatable concentricity. A recommended feed in steel up to 500 N of 0.16 mm per rev helps to achieve the intended cutting action and surface quality; adherence to this parameter supports long tool life and predictable machining results. The combination of these dimensional specifics and the material choice makes the cutter suitable for both workshop maintenance and light production tasks.

FAQ

Which materials can be machined with this countersink?
The TECWERK through‑hole countersink is suitable for steel, cast iron and non‑ferrous or light metals, delivering clean chamfers and effective deburring across these substrates.

How does the through‑hole design improve machining?
The through‑hole enables chip evacuation through the drilled hole, preventing chips from jamming at the cutting edge and reducing chatter and burr formation during countersinking.

What are the relevant dimensions for tool clamping?
The tool features a 12 mm cylindrical shank and an overall length of 85 mm, compatible with standard chucks and holders for reliable concentricity.

What feed and speed settings are recommended?
Best results are achieved at low cutting speed with a recommended feed in steel up to 500 N of 0.16 mm per rev, which supports the intended shearing action and prolongs tool life.

Is this countersink suitable for production use?
Yes; the combination of HSS‑Co material, through‑hole chip evacuation and standardised geometry makes it appropriate for both workshop maintenance and light production environments.
