TECWERK centre drill DIN 333 Form R – HSS, 2.50 mm, 60°

A TECWERK centre drill DIN 333 Form R designed to produce accurate, radiused centre bores for general metalworking and preparatory spotting operations

• High-speed steel (HSS) for extended tool life
• DIN 333 Form R with radius for secure centring
• 60° countersink angle for standard centre holes
• 6.3 mm shank for common collet and chuck systems

Accurate centring for reliable machining starts

The main benefit of a dedicated centre drill is repeatable, concentric pilot holes that prevent runout on subsequent operations. Constructed from HSS, this tool offers a balance of toughness and hardness suitable for routine workshop use. The DIN 333 Form R profile incorporates a small radius at the tip, producing a robust centre bore that aligns workpieces securely for turning or drilling. The included 60° countersink complies with common centre specifications, ensuring compatibility with standard live and dead centres. These features translate into reduced rework and steadier spindle behaviour during finishing passes.

Built for predictable feeds and compatibility

Engineered for straightforward integration into production workflows, the tool features a 2.50 mm diameter cutting tip, an overall length of 45 mm, and a 6.3 mm shank, which suits many collets and small chucks. The cutter is right-hand cutting and intended for general use without a protective countersink, simplifying handling and tool change. For machining mild to medium steels, a recommended feed is 0.03 mm/rev up to the stated material resistance, which provides a reliable compromise between cutting force and tool life. These measurable parameters enable process planners to set feeds and speeds with confidence, reducing trial-and-error at the machine.

Practical workshop guidance and typical applications

This centre drill is intended primarily for preparatory centring in metalworking: producing centre bores per DIN 332 Sheet 1 Form R, initiating accurate turning set-ups, and creating starter holes for subsequent drills. Supplied in practical sets, the tool allows efficient replacement and keeps tooling inventories straightforward. Its combination of HSS material, standardised geometry and compact dimensions makes it suitable for trade workshops, maintenance departments and light production environments where precision and repeatability are required. For customers seeking consistent results across batches, the design minimises wobble and helps maintain concentricity throughout multi-stage processes.

FAQ

What is the intended use of this centre drill?
The TECWERK centre drill is intended for producing precise centre bores and starter holes for turning and drilling, conforming to DIN 332 Sheet 1 Form R.

Which materials can be machined with this tool?
This HSS centre drill is suitable for general metalworking; the specified feed rate of 0.03 mm/rev applies for steels within the stated resistance range.

How does the DIN 333 Form R geometry affect performance?
Form R includes a small radius at the tip that increases contact stability, so the centre bore resists deformation and improves concentricity when mounting between centres.

What machine interfaces are compatible with the shank size?
The 6.3 mm shank fits common small-collet systems and chucks used in workshop lathes and drill presses, allowing straightforward mounting and accurate rotation.

Is a protective countersink included?
This design is supplied without a protective countersink; it is configured for direct centring tasks where a radiused tip is required.
