1mm Centre Drill DIN 333 Form A Extra-Long HSS-Co 60° Tip, Right-Hand - TECWERK

Benefit from the combination of HSS‑Co construction, DIN 333 Form A geometry and an extra‑long overall length for reliable, repeatable centring operations; order the centre drill directly via Metav Werkzeuge or consult our specialists for application advice.

TECWERK centre drill DIN 333 Form A — 1.00 mm, HSS‑Co, extra‑long

A TECWERK centre drill DIN 333 Form A designed for precision centring and the production of centre holes to DIN 332 without a protective countersink, suitable for workshop and industrial preparation tasks.

• HSS‑Co for improved heat resistance
• DIN 333 Form A geometry for accurate centring
• Extra‑long design for deep reach
• Right‑hand cutting with 60° countersink angle

Precise centring that reduces run‑out and rework

The DIN 333 Form A geometry with a 60° countersink angle produces reliably centred starts for turning and drilling operations, reducing wobble and avoiding premature tool wear. For small diameters such as 1.00 mm, consistent centring prevents hole eccentricity and supports subsequent operations like turning or drilling. This precision geometry is particularly valuable in repeat production where positional accuracy determines final part quality.

Robust cutting performance for workshop use

Manufactured from HSS‑Co (cobalt high‑speed steel), the tool combines hardness with elevated heat resistance to maintain cutting edges under intermittent or continuous cutting loads. The material choice results in longer tool life compared with standard high‑speed steel when machining conventional steels. Recommended cutting behaviour includes a feed of 0.02 mm/rev in steel up to 800 N, paired with the right‑hand cutting direction for conventional spindle rotation and reliable chip evacuation.

Extra reach and secure clamping for practical handling

The extra‑long overall length of 120 mm and a 4 mm shank diameter deliver access to deeper centre positions while enabling stable clamping in small‑capacity chucks or collets. The over‑long design reduces the need for extensions or special fixturing in many setups, while the absence of a protective countersink indicates that the tool is optimised specifically for making centre holes to DIN standards rather than for chamfering. The right‑hand cutting orientation ensures familiar handling and predictable performance.

Practical applications and who benefits most

Engineers, tool‑room technicians and general workshop personnel will find this centre drill well suited to producing starter holes for turning, drilling and reaming processes. The combination of a slim 1.00 mm tip, reinforced material and extra length makes the tool appropriate for precision work on small components as well as preparatory centring on larger assemblies. Guidance is available for selecting feeds and clamping options to integrate the tool smoothly into existing workflows.

FAQ

What material is the tool made from and why is that beneficial?
The centre drill is made from HSS‑Co, a cobalt‑alloyed high‑speed steel that offers improved heat resistance and longer edge life compared with standard HSS, especially under higher cutting temperatures.

Which standards and geometry does the tool follow?
The tool complies with DIN 333 Form A and features a 60° countersink angle suitable for producing centre holes according to DIN 332 without a protective countersink.

What are the recommended machining parameters for steel?
For steels up to 800 N the recommended feed is 0.02 mm per revolution; the drill is right‑hand cutting and suited to conventional spindle rotation.

Can this drill reach deep centring positions?
Yes — the extra‑long overall length of 120 mm combined with a 4 mm shank provides additional reach for deeper centre positions while maintaining secure clamping.

Which applications and environments suit this centre drill?
The tool is intended for preparatory centring in turning and drilling operations in workshops, tool rooms and small industrial production, where accurate hole starts and repeatability are required.
