Benefit from durable HSS construction and an extra‑long, chatter‑free three‑flute design that delivers clean chamfers even in demanding materials; order the TECWERK countersink directly via Metav Werkzeuge or ask our consultants if needed.

TECWERK Countersink DIN 335 C Ø10.4 mm (HSS, extra‑long, 90°)

The TECWERK Countersink DIN 335 C Ø10.4 mm is a high‑performance, extra‑long countersink for chamfering and deburring holes in steel, cast iron and non‑ferrous metals.

• HSS material, DIN 335 C standard
• 90° tip for standard chamfering
• Three‑flute geometry for chatter‑free cutting
• Extra‑long cylindrical shank for deep reach

Reliable chamfers and reduced rework through hardened HSS geometry

The HSS tool steel and DIN 335 C specification ensure a consistent edge geometry that maintains form under intermittent loads. This countersink produces a precise 90° chamfer which reduces the need for secondary finishing. The combination of robust material and standardised geometry supports repeatable results in series production, lowering scrap rates and assembly rework.

Higher productivity with three‑flute, chatter‑free cutting

The three‑flute configuration delivers a more balanced cutting action than two‑flute variants, resulting in a chatter‑free cut and improved surface finish. The tool is optimised for a recommended feed of 0.12 mm/rev in steel up to 500 N, which translates into steady material removal and predictable cycle times. For shops focused on throughput, this geometry helps keep processes stable and reduces interruptions from poor surface quality.

Extended reach and versatile material compatibility

An extra‑long overall length combined with a cylindrical shank provides extended reach into deeper bores and through stepped components while remaining compatible with standard toolholders. The countersink is suitable for steel, cast iron and non‑ferrous metals, making it a practical choice for workshop tool cabinets where a single tool must serve multiple tasks. Accessibility and versatility reduce the need for frequent tool changes during complex setups.

Practical benefits for everyday workshop use

Designed for straightforward handling in production environments, the tool’s cylindrical shank supports secure clamping and simple replacement when worn. The robust edge geometry of the countersink improves life span under typical deburring and chamfering loads, providing a low‑maintenance option that supports consistent assembly fit and finishing. When process tolerances matter, this design contributes to fewer fitting issues and faster downstream operations.

FAQ

What materials can this countersink process reliably?
The TECWERK countersink is designed for steel, cast iron and non‑ferrous metals, providing dependable chamfers and deburring across these material groups.

Is the tool suitable for deep or recessed holes?
Yes, the extra‑long overall length and cylindrical shank make the countersink appropriate for deeper bores and recessed features where additional reach is required.

How does the three‑flute design affect performance?
The three‑flute geometry on the TECWERK countersink improves balance and reduces chatter, producing a cleaner finish and more consistent chamfer dimensions compared with two‑flute alternatives.

What feed rate should be used in steel?
Follow the guideline of 0.12 mm/rev in steel up to 500 N for steady cutting behaviour and predictable surface quality with this countersink.

Can this countersink be re‑sharpened or reground?
Regrinding depends on service life and local workshop capability; the countersink’s HSS construction typically allows regrinding, but evaluation of edge geometry and remaining material is recommended before reconditioning.
