TECWERK centre drill DIN 333 Form A, Ø 6.3 mm, HSS

TECWERK centre drill DIN 333 Form A, Ø 6.3 mm, HSS is a precision centring tool designed to produce standard-compliant centre holes for general metalworking applications

• HSS solid construction
• DIN 333 Form A standardised geometry
• 60° countersink angle for precise centring
• Feed 0.05 mm/rev in steel up to 800 N

Accurate starts for repeatable drilling quality

The DIN 333 profile with Form A geometry provides a controlled, repeatable method to produce a true centre hole with a 60° countersink angle. That defined geometry reduces lateral runout when a larger drill or lathe tool follows, improving hole alignment and part tolerances. The use of HSS ensures a balance between toughness and hardness suitable for general workshop operations; the result is predictable tool behaviour and fewer rejects in serial production.

Robust construction for everyday workshop demands

Machined from high-speed steel, the tool offers reliable mechanical resistance under standard centring loads. The specification includes a recommended feed of 0.05 mm/rev in steel up to 800 N, which describes the typical forward motion per spindle revolution when used in such materials; following this parameter helps maintain clean cutting action and consistent hole geometry. The centring drill is intended for broad application in metalworking rather than specialised exotic alloys, supporting efficient workshop workflows and straightforward tool handling.

Practical application and process advantage

Designed for producing centre holes according to DIN 332 without an additional protective countersink, the device streamlines the preparatory step before drilling or turning. This capability shortens set-up time and reduces the need for extra operations, which is particularly beneficial in mixed-production environments. Where process clarity is required, the centring drill’s standardised form aids tool selection and machining documentation, helping to integrate the operation into CNC programmes or manual processes with predictable outcomes.

FAQ

What is the primary purpose of this centre drill?
The centre drill is intended to produce standard-compliant centre holes with a 60° countersink, creating a reliable start point for subsequent drilling or turning operations.

Which materials is the tool suited for?
TECWERK’s centre drill in HSS is specified for general metalworking use; the technical data states a feed of 0.05 mm/rev for steel up to 800 N as a processing guideline.

Does the tool require a protective countersink when used to DIN 332?
No protective countersink is required for producing centre holes according to DIN 332 when using this DIN 333 Form A centre drill.

How should the feed value of 0.05 mm/rev be interpreted in practice?
The feed figure indicates the axial advance per spindle revolution under the stated condition (steel up to 800 N); it serves as a guideline to achieve consistent cutting action and hole geometry.
