Centre drill DIN 333 Form A, 2.5 mm – solid carbide, right‑hand cutting (TECWERK)

The Centre drill DIN 333 Form A 2.5 mm is a compact solid‑carbide tool designed to produce standard centre holes and reliable pilot points for subsequent drilling and turning operations across a wide range of materials.

• Solid carbide (VHM) construction
• DIN 333 Form A centring geometry
• 60° countersink for standard centre holes
• Shank Ø 6.3 mm, overall length 45 mm

Precise centring for consistent downstream accuracy

The DIN 333 Form A geometry is engineered to create accurate, repeatable centre holes that reduce runout in subsequent machining. The combination of Form A geometry and a 60° countersink produces a clean seating for live centres and pilot drills, thereby reducing wobble and improving concentricity. This leads to fewer rejects and more predictable tool life in follow‑up processes, a rational improvement in process stability for production environments.

Durable solid‑carbide build for demanding materials

Made from solid carbide (VHM), the tool offers high stiffness and wear resistance compared with high‑speed steel alternatives. This hardness minimises deflection and maintains tip geometry under load, extending service intervals when working with tougher materials such as high‑strength steels and manganese‑hardened alloys. The robust construction pays off through reduced rework and sustained accuracy in repetitive centring tasks.

Optimised cutting direction and process data for efficiency

The right‑hand cutting orientation is matched to standard spindle rotations, while the specified feed parameter of 0.1 mm/rev in steel up to 800 N gives a practical baseline for machining. The compact shank Ø 6.3 mm ensures compatibility with common collet systems and tool holders, enabling quick tool changes and short cycle times. These process characteristics support a rational improvement in throughput and predictable machining results.

Versatility across materials and workshop workflows

Suitable for producing centre holes to DIN 332, the bit is applicable to a broad material spectrum: high‑strength steels, steel cast, grey cast iron, hard cast iron, CrNi stainless steels, light and non‑ferrous metals, fibre‑reinforced plastics and other duroplasts. This versatility simplifies inventory and makes the tool a practical choice for mixed‑material workshops. Supplied via Metav Werkzeuge’s Emmerich stock, the product benefits from a reliable supply chain and a quality‑filter approach for the European market.
