TECWERK conical countersink DIN 335 C Ø 19 mm — HSS Nano, 3‑flute

A TECWERK conical countersink DIN 335 C Ø 19 mm engineered for efficient, high‑precision countersinking in steel, stainless steels, aluminium, brass and technical plastics.

• HSS with Nano coating for high wear resistance
• 90° conical geometry for standard countersinking
• Three‑flute design for ultra‑smooth running
• Lower feed force; faster, longer tool life

Faster, more efficient countersinking for production

The optimised 90° conical geometry combined with a three‑flute cutting layout reduces cutting forces and improves chip evacuation. This results in a notably lower feed force, which makes setup easier on manual machines and reduces load on CNC spindles. In practice, operators will notice quicker cycle times thanks to a process that can be up to 30% faster than conventional countersinks, while maintaining a clean, burr‑reduced finish on most common workshop materials.

Extended lifetime and consistent performance

Constructed from HSS and finished with a Nano coating, the tool achieves very high wear resistance and hot hardness, helping to extend service intervals. The combination of a specially developed chip space and variable relief leads to smoother cutting conditions and reduced flank wear, contributing to up to 60% higher stand times compared with uncoated equivalents. For production environments where tool changes interrupt throughput, this translates directly into better uptime and lower tool handling effort.

Designed geometry that reduces operator effort

The shank is supplied with a shank with three flats from nominal Ø 8.3 mm, ensuring secure clamping and reduced slippage in collets and chucks. The variable relief and flute design also deliver an extremely quiet run, which improves operator comfort and reduces vibration transfer to the workpiece. For machinists unfamiliar with the terminology: variable relief means the clearance behind the cutting edge changes along its length to balance cutting action and edge strength, producing a smoother result with less tendency to chatter.

Broad material compatibility for workshop flexibility

The countersink is specified for machining steel, stainless and heat‑resistant steels, aluminium, brass and plastics, making it a versatile choice for mixed‑material production runs. Recommended feed in steel at cutting loads up to 800 N is 0.2 mm/rev, which provides a reliable starting point for programming or manual feeds; actual feed may be adjusted according to machine rigidity and component tolerance. The combination of materials and geometry supports consistent chamfer quality across different substrates without the need for multiple dedicated tools.

FAQ

What materials can be machined with this countersink?
The TECWERK conical countersink (DIN 335 C Ø 19 mm, SKU 2000865181NW) is specified for use on steel, stainless and heat‑resistant steels, aluminium, brass and various plastics.

What feed should be used as a starting point in steel?
A practical starting feed in steel under cutting loads up to 800 N is 0.2 mm/rev; adjust according to machine rigidity and workpiece tolerance for optimal results.

How does the Nano coating benefit the tool?
The Nano coating increases wear resistance and thermal stability, which helps maintain cutting edge integrity and extends tool life under continuous production conditions.

Is this countersink suitable for handheld drilling or only for CNC?
The three‑flute geometry and shank with three flats provide secure clamping for both handheld machines with appropriate chucks and for CNC tooling systems, enabling versatile workshop use.

What performance improvements can be expected versus standard countersinks?
Compared with standard uncoated countersinks, users can expect lower feed force, an extremely smooth run, up to 60% longer tool life and up to 30% faster countersinking, depending on application and machine setup.
