TECWERK countersink DIN 335 C — 90° · D 15 mm · HSS‑Co · 3‑flute

The TECWERK countersink DIN 335 C is a 90° conical countersink with a cylindrical shank, designed for chamfering and deburring holes in steel, cast parts and non‑ferrous metals in industrial and workshop applications.

• DIN 335 C standard geometry
• 90° cutting angle for precise chamfers
• 3‑flute design for chatter‑free cutting
• HSS‑Co for stainless and heat‑resistant steels

Faster, more stable chamfering with reduced vibration

The three‑flute geometry delivers a rattle‑free cut, reducing vibration and improving surface finish compared with two‑flute variants. This results in fewer rejects and shorter rework times, especially on delicate bores. The combination of the 3‑flute design and the standardised DIN 335 C profile ensures repeatable chamfers and a consistent edge, which benefits batch production and serial tasks by lowering scrap rates and stabilising cycle times.

Material resilience for demanding workpieces

Manufactured from HSS‑Co, the cutters are suitable for a wide range of materials: steel, cast iron and non‑ferrous metals, and additionally for stainless and heat‑resistant steels where higher temperature resistance is required. The specification includes a recommended feed in steel up to 500 N: 0.14 mm/rev, which provides a practical baseline for setting machining parameters. Explaining this simply: the feed figure helps select a safe starting point for feed per revolution to balance tool life and surface quality.

Precise geometry for consistent edge preparation

A true 90° chamfer angle produces standard countersinks for typical fastener seating and edge deburring. The cylindrical shank secures reliably in conventional collets and holders, allowing straightforward integration into existing tool setups. Conforming to DIN 335 C means compatibility with common machining standards, simplifying tool selection and ensuring predictable results in assembly or finishing operations.

Designed for workshop efficiency and predictable supply

The tool is delivered as a single item, making stock control straightforward. Its robust construction and proven geometry reduce the need for frequent replacements, supporting continuous operation on the shop floor. For teams seeking dependable measuring and machining supply chains, Metav’s offering combines accessible availability with technical competence — a practical fit for industrial workshops, maintenance departments and contract manufacturers aiming to streamline tooling assortments.

FAQ

What materials can be machined with this countersink? This TECWERK countersink is suitable for steel, cast parts and non‑ferrous metals; the HSS‑Co grade also permits use on stainless and heat‑resistant steels.

What does the DIN 335 C designation mean for the tool? DIN 335 C specifies the geometric standard for conical countersinks; adherence to DIN 335 C ensures predictable chamfer angles and interchangeability in industrial setups.

How should feed and speed be selected for steel? Use the recommended feed of 0.14 mm/rev in steel up to 500 N as a starting point, then adjust spindle speed and feed to balance surface finish and tool life for the specific machine and workpiece.

Is the shank compatible with standard collets? The cylindrical shank is designed for secure clamping in standard collets and holders commonly used in milling and drilling stations, enabling straightforward integration.

Does the three‑flute design affect surface finish? Yes, the 3‑flute configuration provides a chatter‑free cut and typically yields a smoother chamfer finish compared with fewer‑flute alternatives.
