Centre drill DIN 333 Form A D 0.5 mm HSS (right‑hand) — TECWERK

The Centre drill DIN 333 Form A D 0.5 mm HSS provides a reliable method for producing accurate centring holes for turning and drilling operations in general workshop and production environments.

• HSS, DIN 333 Form A geometry
• 60° countersink angle for DIN 332 centres
• Suitable for general use and robust starting holes
• Right‑hand cutting for standard drilling spindles

Consistent, accurate centre holes for improved process reliability

The short, rigid point geometry specified by DIN 333 Form A ensures reliable positioning of the drill bit on the workpiece and reduces walk‑off when starting a hole. Constructed from HSS, the tool retains sharpness at the cutting edge while withstanding typical workshop conditions; this results in repeatable centre holes that lead to more accurate subsequent turning or drilling processes. The standard 60° countersink angle matches the requirements of DIN 332 for centre holes, so the resulting seats are compatible with centres and live‑centres used in lathes and similar machines.

Optimised cutting parameters that support efficiency and surface quality

The geometry and material combine to permit controlled feeds: where the workpiece and clamping allow, a feed of 0.01 mm per revolution in steel up to 800 N provides a clean, burr‑reduced start without excessive axial loads. This parameter guidance helps integrate the tool into automated or manual setups with predictable chip formation and a reduced risk of tip breakage. The right‑hand cut fits conventional spindle rotation and standard chucks, enabling quick tool changes and straightforward process planning for both prototype and small‑batch production runs.

Practical workshop use and handling for long service life

The tool is intended for general application and for producing centre holes without a protective countersink, following the DIN specification for direct centring. The compact design minimises overhang, lowering the bending moment and helping to protect the tip under normal operating conditions. When stored and used according to standard workshop practice — secure clamping, correct back‑off between passes and periodic inspection of the cutting edge — the drill offers stable performance and predictable replacement intervals. For bespoke setups or unusual materials, consult technical guidance to adapt feeds and speeds safely.

FAQ

What materials is this centre drill suitable for?
The centre drill is made from HSS and is specified for general use; it is suitable for standard steels where the feed recommendation of 0.01 mm per revolution up to 800 N applies, and it will perform well for typical workshop steels and similar materials.

How does the 60° countersink angle affect compatibility with centres?
A 60° countersink angle matches DIN 332 centre dimensions, ensuring that centres and live‑centres seat correctly in the machined centre holes and provide accurate support during turning.

Is this centre drill compatible with standard drill chucks and spindles?
Yes. The right‑hand cutting geometry is intended for conventional spindle rotation and standard chucks; installation follows normal tool‑holding procedures for small centre drills.

What is meant by Form A in DIN 333?
Form A describes a short, rigid point geometry designed for reliable centring and minimal lateral flex, providing stable starts particularly in standard workshop set‑ups.
