4mm Centre Drill DIN 333 Form A 60° Countersinkless HSS-Co, Right-Hand Cutting - TECWERK

Precision centre holes in demanding materials are ensured by the combination of HSS‑Co construction, DIN 333 Form A geometry and a 60° countersink; order the centre drill directly via Metav Werkzeuge or consult our advisors for application support.

TECWERK centre drill DIN 333 Form A — HSS‑Co, 4.00 mm, 60° countersink

The TECWERK centre drill DIN 333 Form A is a robust centre‑drilling tool designed for producing accurate centre holes in high‑strength and corrosion‑resistant steels.

• HSS‑Co for high‑strength and stainless steels
• DIN 333 Form A geometry for centred holes
• 60° countersink angle for secure seating
• Right‑hand cutting with 4.00 mm diameter

Precision for hard and corrosion‑resistant materials

Manufactured in HSS‑Co, this centre drill delivers improved heat resistance and wear performance compared with standard high‑speed steels. The cobalt alloy composition supports reliable drilling into materials with strength above 800 N/mm² and into corrosion‑resistant CrNi steels, maintaining edge integrity under elevated temperatures. The combination of material and geometry reduces rework and tool changes, which helps sustain a consistent machining flow in industrial and workshop environments while preserving component concentricity.

Geometry that guarantees secure seating and accurate alignment

The DIN 333 Form A geometry with a 60° countersink is optimised for producing secure centre holes that guide subsequent turning or drilling operations. Because this version is specified without a protective countersink, it produces a concise centre point suited for precise alignment and dependable seating of workpieces. The resulting centre hole aids in avoiding runout during clamping and supports predictable tool paths, which is particularly beneficial in serial production and when repeatability is required.

Practical operation and compatibility with standard tooling

With a nominal diameter of 4.00 mm, an overall length of 56 mm and a 10 mm shank, the tool fits common holders and drill chucks while preserving rigidity for small‑diameter centring tasks. The right‑hand cutting orientation matches conventional spindle rotation and the recommended feed in steel up to 800 N/mm² of 0.03 mm per rev offers a balance between surface finish and tool life. These operational parameters help planners specify feeds and speeds confidently and integrate the drill into existing workflows with minimal setup changes.

Efficiency and workshop reliability

Designed for focused centre‑drilling tasks, the tool reduces cycle time by providing a repeatable, high‑quality datum for subsequent machining stages. The HSS‑Co substrate extends service intervals and reduces the frequency of tool changes, improving uptime in busy shops. Combined with Metav’s quality assurance and logistics from Emmerich, this centre drill supports a pragmatic supply chain approach for firms that seek both precision and dependable delivery.

FAQ

Is this centre drill suitable for stainless and high‑strength steels? Yes. The TECWERK centre drill (SKU 2000861583NW) in HSS‑Co is specified for machining high‑strength materials above 800 N/mm² and corrosion‑resistant CrNi steels.

What does DIN 333 Form A mean for the produced centre hole? DIN 333 Form A indicates a standard centre‑drilling geometry intended to create a 60° centre suitable for alignment and secure seating; the tool produces centre holes per that standard without a protective countersink.

Which feed and cutting direction are recommended? A feed of 0.03 mm per rev in steels up to 800 N/mm² is recommended; the tool uses a right‑hand cutting action compatible with standard spindles.

Will the shank size fit common holders? Yes. The tool has a 10 mm shank, which is compatible with typical drill chucks and collet holders for small‑diameter centring operations.

How does HSS‑Co benefit centre‑drilling tasks? HSS‑Co delivers enhanced heat resistance and wear performance compared with conventional HSS, which helps preserve cutting edges during centring in demanding materials.
