TECWERK centre drill DIN 333 Form A — 4 mm, HSS TiN

TECWERK centre drill DIN 333 Form A for precise centre holes and fast, reliable locating prior to turning and drilling operations in general workshop and production environments

• HSS with TiN coating for longer life
• DIN 333 Form A for accurate centring
• 60° countersink angle for standard centre holes
• Feed rate 0.03 mm/rev in steel up to 800 N

Precision and durability for dependable locating

The combination of high-speed steel (HSS) and a titanium nitride (TiN) coating provides a robust cutting edge that resists wear and reduces adhesion. This results in consistent hole quality and less frequent regrinding, which supports uninterrupted production. The hardened substrate and surface layer also help maintain geometry under repeat use, so centring remains accurate over longer tool life, lowering the total cost of ownership for the workshop.

Geometry engineered for standard centre holes

The Form A geometry conforms to DIN 333 and is matched to the conventional 60° countersink angle used for centre holes to DIN 332. That combination ensures the centre bore and countersink align correctly for subsequent turning and drilling operations. The right-hand cutting design delivers predictable chip flow and simplifies process setup. For users unfamiliar with the standards: DIN 333 defines the centre drill shape, while the 60° angle produces the required seat for lathe centres and pilot drills.

Controlled machining parameters for reliable results

Specified process data such as a feed of 0.03 mm/rev in steel up to 800 N gives a practical starting point for machining trials and tool planning. Working within these parameters helps achieve a clean, true seat without undue tool stress. The modest feed and the TiN surface reduce friction, which can improve hole quality and lower the risk of burr formation. These measurable properties support efficient cycle planning in both small workshops and production lines.

Practical handling and workshop benefits

The compact 4 mm diameter makes this centre drill well suited for general locating tasks where accuracy and repeatability matter. The tool requires standard toolholders and is compatible with typical workholding on lathes and drill presses. With the TiN coating reducing friction, operators can expect improved chip evacuation and less built-up edge. Metav’s approach to supply and quality control ensures that every tool leaving the warehouse has been selected to meet industrial expectations, supporting dependable day-to-day use.

FAQ

What materials is this centre drill suitable for?
The TECWERK centre drill is specified with a feed value for steel (up to 800 N) and is intended for general workshop use where steel locating holes are required; adjust cutting data for other materials.

What advantages does the TiN coating provide?
The TiN coating increases surface hardness, reduces friction and adhesion, and helps prolong tool life while maintaining consistent hole quality.

Which standards govern the geometry of this tool?
The tool follows DIN 333 Form A and is designed to produce centre seats compatible with DIN 332 60° centre holes, ensuring predictable fit for centres and pilot drills.

How should the feed and cutting direction be set?
Use the right-hand cutting direction and start from the provided guideline of 0.03 mm/rev in steel up to 800 N, then optimise speed and feed for the specific machine and workpiece.
