TECWERK centre drill DIN 333 Form A — Solid carbide, 4.00 mm, 60°

A TECWERK centre drill DIN 333 Form A designed for accurate centring and short pilot holes across steels, cast irons and engineered plastics in industrial and workshop environments

• Solid carbide (VHM), robust and wear-resistant
• DIN 333 Form A, 60° centring angle
• Right‑hand cutting for conventional setups
• Suitable for steels, cast irons and plastics

Accurate centring for reliable pilot holes

The tool delivers repeatable centring thanks to the DIN 333 Form A geometry and the 60° countersink, which together create a precise starting point for subsequent drilling or turning operations. This geometry reduces run‑out and helps maintain concentricity when producing pilot holes for turning centres or drilling sequences. The short pilot profile stabilises the tool in the spindle or chuck, so the initial hole is true and ready for further machining without additional rework.

Long tool life and broad material range

Manufactured from solid carbide (VHM), the centre drill offers high wear resistance and thermal stability compared with HSS alternatives. The design supports machining of high‑strength steels, steel castings, grey and hard cast irons, CrNi steels, light and non‑ferrous metals, and fibre‑reinforced plastics and other thermosets. The execution is without protective countersink, which keeps the geometry focused on performance and facilitates sharpening or regrinding strategies in professional shops.

Predictable machining parameters for process control

The tool is optimised for industrial feed and torque conditions: feed in steel up to 800 N: 0.11 mm/rev offers a reliable starting point for process planning, while the right‑hand cutting orientation suits conventional spindle directions. With a 4.00 mm tip diameter, 56 mm overall length and 10 mm shank, the tool can be held securely in standard collets or chucks; the feed value is a per‑revolution parameter, meaning the workpiece or spindle should advance by 0.11 mm for each spindle rotation under the specified cutting conditions to maintain chip formation and surface quality.

Simple integration into production workflows

Thanks to the standard DIN 333 form and familiar shank dimension, the centre drill fits seamlessly into existing tool sets and fixtures, reducing setup time and lowering the risk of handling errors. The combination of consistent geometry and solid‑carbide construction ensures fewer tool changes and more uptime, which supports efficient batch production and quality assurance in small to medium series work. Where reproducibility matters, this tool contributes to a smoother process chain and predictable output quality.

FAQ

What is the countersink angle of this centre drill?
The TECWERK centre drill has a 60° countersink angle in accordance with DIN 333 Form A, which provides a standardised tip for reliable centring.

Which materials can the TECWERK centre drill machine?
The TECWERK centre drill is suitable for high‑strength steels, steel castings, grey and hard cast irons, CrNi steels, light and non‑ferrous metals, and fibre‑reinforced plastics, as specified for broad workshop and industrial use.

What feed and cutting direction are recommended?
Recommended reference: feed in steel up to 800 N = 0.11 mm/rev; the tool is right‑hand cutting, so feeds and spindle directions should match standard right‑hand machining setups.

What shank size and overall length does the tool have?
The centre drill features a 10 mm shank and an overall length of 56 mm, suitable for standard collet chucks and short overhang applications.

Is the tool supplied with a protective countersink?
The product is delivered without protective countersink (ohne Schutzsenkung), leaving the manufacturer geometry intact for direct use or customised preparation.
