Conical countersink DIN 335C Ø6.3 mm, 90° – TECWERK (HSS, TiAlN, 3 flutes)

Conical countersink DIN 335C Ø6.3 mm for countersinking and deburring holes in steel, cast iron and non‑ferrous metals

• DIN 335 C standard, 90° countersink
• 3 flutes for vibration-free cutting
• HSS with TiAlN coating for long life
• Cylindrical shank for secure clamping

Precision and efficiency for series and workshop use

The Conical countersink DIN 335 C Ø6.3 mm combines standardised 90° geometry with 3 flutes to produce reliable chamfers and fast deburring in repetitive workflows. The flute arrangement delivers a vibration‑free cut and steady material removal, reducing the need for secondary finishing. Made from HSS and enhanced with a TiAlN coating, the tool shows improved heat resistance and wear performance under sustained use; the recommended feed in steel up to 500 N is 0.09 mm/rev, which supports predictable cycle times and process planning.

Versatile compatibility that reduces downtime

The tool is specified for use on steel, cast iron and non‑ferrous metals, making it suitable for maintenance, production and workshop applications where flexibility is required. The TiAlN surface helps to limit built‑up edge and extend tool life when operating at higher temperatures, while the HSS substrate offers a good balance between toughness and hardness. The cylindrical shank allows straightforward clamping in standard tool holders and fast tool changes, cutting set‑up time and keeping machine throughput steady.

Practical handling and process reliability

Integration is simplified by DIN conformity and the cylindrical shank, which together facilitate repeatable clamping and alignment. The rattle‑free cut provided by the three flutes minimises chatter and surface damage, decreasing rework rates and improving first‑pass quality. Supplied as a single unit (packaging unit 1), the countersink supports traceable procurement and clear tool management; measurable parameters and standard geometry make it easy to specify for both new and existing machining programmes.

FAQ

What materials is this countersink suitable for?
The TECWERK conical countersink DIN 335C Ø6.3 mm is designed for steel, cast iron and non‑ferrous metals, as stated in the product specification (SKU 2000865222NW).

What advantages does the TiAlN coating provide?
The TiAlN coating on the HSS substrate increases heat resistance and reduces wear, improving tool life and performance during prolonged countersinking and deburring operations.

What feed rate is recommended for use in steel?
A longitudinal feed of 0.09 mm/rev in steel up to 500 N is given as a guideline to achieve stable cutting and consistent surface quality.

Is there a version for higher temperature or tougher alloys?
The data indicates an HSS‑Co option for greater demands; HSS‑Co variants are typically used for tougher, heat‑resistant steels where additional hot hardness is beneficial.

How is the tool clamped and how does it affect process reliability?
The cylindrical shank ensures reliable clamping in standard tool holders, and the three‑flute geometry delivers a rattle‑free cut that reduces chatter and the need for rework.
