TECWERK 90° Countersink DIN 335 C, Ø19 mm, HSS, 3‑flute

The TECWERK 90° Countersink Ø19 mm is a high‑speed‑steel countersink designed for precise chamfering and deburring of drilled holes in steel, cast iron and non‑ferrous metals

• HSS to DIN 335 C standard
• 90° chamfer angle for standard countersinks
• Three‑flute geometry for chatter‑free cutting
• Cylindrical shank for secure toolholding

Accurate chamfers and clean deburring for consistent assembly

The combination of HSS material and the DIN 335 C specification provides a solid technical basis for repeatable results in production and workshop environments. The 90° chamfer geometry and Ø19 mm cutting diameter make this tool suitable for standard countersinking tasks, converting drilled holes into ready‑to‑fasten features with minimal rework. Thanks to the hardened and ground cutting edges, the tool maintains form stability under load, so the process of countersinking and deburring becomes predictable and easier to integrate into existing workflows. This predictability reduces inspection time and contributes to smoother assembly operations.

Stable, chatter‑free cutting for improved surface quality

The three‑flute cutter geometry is engineered to deliver a chatter‑free cutting action, which translates into improved surface finish and longer tool life compared with two‑flute variants. The cylindrical shank ensures concentric clamping and reliable run‑out behaviour in common toolholders and drill chucks. A defined machining parameter is the recommended feed: in steel (up to 500 N) a feed of 0.14 mm/rev is indicated, which supports consistent cutting loads and avoids irregular finishes. By favouring stable cutting conditions over excessive speed, the tool reduces the risk of torn edges and uneven chamfers, saving downstream deburring effort and improving first‑pass quality.

Broad material compatibility and workshop readiness

This countersink is specified for use in steel, cast iron and non‑ferrous metals, making it a versatile choice for general workshop duties as well as industrial production tasks. The HSS construction balances toughness and wear resistance for manual and machine operations alike. Because the geometry is optimised for controlled chip formation, the tool performs well when applied to mixed batches of components commonly encountered in maintenance, repair and small‑series production. For procurement and process planners, the tool represents a straightforward option to standardise countersinking across a range of materials without frequent tool changes.

Practical advantages for procurement and maintenance

The straightforward design—standardised to DIN 335 C, with a cylindrical shank and three cutting edges—facilitates easy replacement and predictable integration into existing tool inventories. The ratter‑free cutting characteristic reduces operator fatigue and the need for repeat finishing, while the robust HSS body permits occasional light regrinding where appropriate for sustainability. As part of a Metav‑filtered product range, this countersink benefits from supplier scrutiny and traceable technical data, helping purchasing teams to reduce supplier variance and secure dependable tool performance across multiple jobs.

FAQ

What materials can this countersink be used on?
The TECWERK 90° countersink is specified for steel, cast iron and non‑ferrous metals, providing versatile deburring and chamfering across common workshop materials.

What is the recommended feed for machining steel?
For steel (up to 500 N) the recommended feed for the countersink is 0.14 mm/rev, which helps to maintain stable cutting conditions and consistent surface quality.

How does the three‑flute design affect machining?
The three‑flute geometry delivers a more uniform cutting engagement that reduces vibration and produces a chatter‑free finish, improving edge quality and extending usable tool life.

Is the shank compatible with standard chucks and toolholders?
The cylindrical shank on the TECWERK countersink is intended for secure clamping in standard drill chucks and collets commonly found in workshops and production machines.

Can this countersink be resharpened?
The HSS construction allows for light regrinding where appropriate; however, resharpening should follow the original geometry to preserve the DIN 335 C profile and ensure consistent performance.
