TECWERK Centre Drill DIN 333 Form A – 3.15 mm, Solid Carbide, 60°

The centre drill DIN 333 Form A is a short, rigid centring tool designed to create precise pilot centres for turning and drilling operations across a wide range of engineering materials.

*Solid carbide construction for long life
*DIN 333 Form A centring geometry
*60° countersink angle for standard centring
*Right‑hand cutting for conventional machining

Precision centring for consistent pilot holes

The combination of DIN 333 Form A geometry and a 60° countersink angle delivers consistently accurate pilot holes that reduce runout at subsequent drilling or turning operations. The short, rigid design concentrates cutting forces at the tip, improving concentricity and repeatability in serial production. As a result, process stability is increased and the risk of rework is minimised, which supports dependable cycle times on both manual and CNC machines.

Engineered for tough materials and extended tool life

Manufactured from solid carbide, this centring tool offers high wear resistance and thermal stability, making it suitable for machining high‑strength steels, various cast irons and many non‑ferrous alloys. The right‑hand cutting orientation ensures conventional chip flow and predictable performance in standard machining setups. By choosing a carbide centring drill, tool change frequency is reduced and cutting-edge integrity is maintained under higher cutting loads, supporting uninterrupted workshop throughput.

Compact dimensions for seamless integration into production

With a diameter of 3.15 mm, shank 8 mm and an overall length of 50 mm, the tool fits common collets and chucks without the need for special adaptors. The design is supplied without protective countersink, keeping the tool true to Form A specification and suitable for producing centre holes to DIN 332. Recommended operating data includes a feed of 0.1 mm/rev in steel up to 800 N, which balances cutting engagement and tool life for repeatable results across batches.

FAQ

Which materials can be machined with this centre drill?
The TECWERK centre drill DIN 333 Form A 3.15 mm is specified for high‑strength steels, steel castings, grey and hard cast irons, manganese‑hard steel, CrNi steels, light and non‑ferrous metals, and fibre‑reinforced plastics as stated in the product data.

What feed and cutting direction are recommended?
A feed of 0.1 mm/rev in steel up to 800 N is indicated for stable machining; the tool is right‑hand cutting, suitable for conventional spindle rotation and standard toolholders.

Will the tool fit common chucks and collets?
Yes. The 8 mm shank and 50 mm overall length make the centring drill compatible with typical 8 mm collets and drill chucks used in workshops and small production cells.

What does “Form A without protective countersink” mean for the workshop?
Form A denotes a short, rigid centre drill profile intended for accurate centre holes; “without protective countersink” means the tip is supplied in the standard Form A geometry without an added protective chamfer, ensuring true centring for machining to DIN 332.

Which standards apply to this centring tool and how is it identified?
The tool conforms to DIN 333 (Form A) and is intended for producing centre holes per DIN 332; identification is by SKU 2000861993NW and the TECWERK brand.
