Centre drill DIN 333 Form A 3.15 mm (HSS‑Co) by TECWERK — 60° tip, 8 mm shank

A centre drill DIN 333 Form A 3.15 mm HSS‑Co designed to produce accurate centre holes for machining and turning, especially in high‑strength and corrosion‑resistant steels

• HSS‑Co construction for high wear resistance
• DIN 333 Form A geometry for precise centring
• 60° tip angle for standard centre holes
• 8 mm shank, Ø 3.15 mm, overall length 50 mm

Durable alloy for high‑strength machining

Manufactured from HSS‑Co, this centre drill is engineered for components with elevated strength requirements. The cobalt‑alloy composition increases red hardness and wear resistance, which supports continuous operation under higher temperatures and tougher cutting conditions. Designed for materials exceeding 800 N/mm² and CrNi (stainless) steels, the tool offers a consistent cutting performance where standard high‑speed cutters might accelerate wear. The specification also cites a recommended feed of 0.03 mm/rev for steels up to 800 N/mm², allowing purchasers to plan machining parameters with predictable tool life.

Geometry that ensures repeatable, conforming centre holes

The DIN 333 Form A profile and 60° tip produce centre holes compliant with DIN 332 standards without a protective countersink, giving a clean, concentric start for subsequent turning or drilling operations. The short, rigid point inherent to Form A minimises deflection and chatter, resulting in precise centre holes and reduced rework. With an 8 mm shank and a nominal diameter of 3.15 mm, the design suits common collet and chuck systems and supports safe, repeatable seating of workpieces on centres.

Production‑ready handling and workshop benefits

Right‑hand cutting and a 50 mm overall length make the tool straightforward to integrate into standard drill holders and tool changers. Packaged in sets of five, the item supports small batch replenishment and shop‑floor availability. The combination of standardised DIN geometry and robust material choice delivers a low‑risk option for purchasing managers seeking durable, easy‑specified centring tools that reduce downtime and maintain process stability in serial production.

FAQ

What materials can this centre drill machine?
The TECWERK centre drill (centre drill DIN 333 Form A 3.15 mm HSS‑Co, SKU 2000861582NW) is specified for materials with tensile strengths above 800 N/mm² and for corrosion‑resistant CrNi (stainless) steels.

Is the tip angle suitable for standard lathe centres?
Yes. The 60° tip conforms to common centre geometry and is intended to produce centre holes that match DIN 332 requirements for turning and supporting workpieces.

What is the recommended feed rate when drilling steel?
A recommended feed of 0.03 mm/rev is indicated for steel up to 800 N/mm²; this offers a balance between tool life and machining efficiency for the specified materials.

Which holders or collets are compatible with the shank?
The tool’s 8 mm shank is compatible with standard 8 mm collets and drill holders; confirm holder clamping tolerances on the machine side before mounting.

How is the tool supplied and arranged for stock control?
The item is supplied in a packaging unit of 5, facilitating straightforward inventory management for production and maintenance planning.
