1.25mm Centre Drill DIN 333 Form R 60° Point Angle HSS Right-Handed Without Countersink - TECWERK

Benefit from precise, DIN‑compliant centring: the HSS construction, 60° countersink angle and right‑cut geometry deliver reliable pilot centres for subsequent drilling and reduced rework. Order via Metav Werkzeuge or contact our specialists for application advice.

TECWERK Centre Drill DIN 333 Form R Ø1.25 mm – HSS, 60° Countersink

TECWERK Centre Drill DIN 333 Form R Ø1.25 mm is a precision centre drill designed for producing repeatable centring holes in general metalworking and workshop environments without protective countersink.

• HSS material for durable cutting performance
• DIN 333 Form R geometry with radius
• 60° countersink angle for standard centres
• Right‑cut for conventional spindle rotation

Increase first‑time accuracy with radiused Form R geometry

The radiused Form R tip is engineered to produce a consistent lead for subsequent drills, improving concentricity and reducing the need for rework. Made from HSS, the tool offers a balanced combination of toughness and wear resistance, suitable for repeated pilot‑drilling operations. The radiused point avoids brittle fracture at the tip and helps centre the following twist drill, which in turn extends cutting tool life and lowers overall production rejects.

Standard compatibility and clear machining parameters

Compliant with DIN 333 and intended to produce centring holes to DIN 332 Sheet 1 Form R, this centring drill features a 60° countersink angle that matches common lathe and drilling practise. The right‑cut geometry is optimised for clockwise spindle rotation on conventional machines. Recommended feed in steel (up to 800 N) is 0.02 mm/rev, providing a reliable baseline for process set‑up and consistent hole quality without operator guesswork.

Workshop efficiency through compact dimensions and practical design

With an overall length of 31.5 mm and a shank diameter of 3.15 mm, the compact design facilitates secure clamping in small chucks and adaptors while keeping overhang low to reduce runout. Supplied without a protective countersink, the drill is intended for direct centring tasks where a defined pilot is required. Supplied in packs of 5, the tool supports steady workshop throughput and simplifies reorder planning.

FAQ

What materials is this centre drill suitable for?
The TECWERK centre drill is made of HSS and intended for general metalworking use; specific material limits depend on the machining setup and cutting data such as the recommended feed of 0.02 mm/rev in steel (≤800 N).

How does Form R differ from a pointed centre drill?
Form R features a radiused tip that reinforces the cutting edge and produces a more robust pilot centre compared with a sharp‑point variant; this results in improved alignment for subsequent drilling operations.

Is the countersink included on this tool?
This item is supplied without protective countersink, designed specifically for creating defined centring holes rather than chamfered starts.

Can this drill be used in handheld drills?
The tool’s shank diameter of 3.15 mm and compact overall length (31.5 mm) allow use in small chucks and adaptors; however, stable clamping and appropriate speeds are recommended for best centring accuracy.

What does right‑cut mean for machining?
Right‑cut indicates the flute geometry is intended for clockwise spindle rotation, which is the conventional direction on most lathes and drilling machines.
