Take advantage of precise centring, robust solid carbide (VHM) construction and a defined 60° countersink for consistent starting holes; order directly via Metav Werkzeuge or consult our specialists for application-specific advice.

Centre drill DIN 333 Form A 1.00 mm – solid carbide, 60° (TECWERK)

A Centre drill DIN 333 Form A 1.00 mm designed for producing exact centring holes in a wide range of engineering materials, from high-strength steels to fibre-reinforced plastics.

• Solid carbide (VHM) for demanding work
• 60° countersink angle for accurate centring
• Complies with DIN 333 Form A and DIN 332
• Right-hand cutting for conventional machines

Reliable starts ensure repeatable machining accuracy

This centring tool is engineered to deliver precise, repeatable starts for subsequent drilling or turning operations. Built to the DIN 333 Form A geometry, the tool produces a defined 60° countersink, which ensures consistent seating and alignment of drill bits and lathe centres. The standard for the resulting centre holes is aligned with DIN 332, giving planners and operators a verifiable basis for process control. For production environments, this means fewer misfeeds and improved first-pass yields.

Durable solid carbide body for extended tool life

Manufactured from solid carbide (VHM), the centre drill provides high stiffness and improved wear resistance compared with high-speed steel alternatives. The material choice supports higher peripheral speeds and a stable cutting edge under interrupted cutting conditions, reducing breakage risk on small diameters. The right-hand cutting geometry is optimised for conventional machining centres and manual lathes, offering predictable chip flow and consistent performance over longer runs.

Broad material compatibility reduces tooling variants

The tool is suitable for a broad spectrum of workpieces, including high-strength steels, steel castings, grey and hard cast iron, manganese-hardened steels, CrNi stainless steels, aluminium and other non-ferrous metals, as well as fibre-reinforced plastics and other duroplastics. This versatility helps to streamline stock lists and simplifies job planning: one centring solution can cover diverse components without compromising hole quality. The absence of a separate protective countersink means the geometry focuses on direct centring performance.

Practical dimensions and recommended machining data for integration

The centre drill features a 1.00 mm diameter, a 3.15 mm shank, and an overall length of 31.5 mm, making it compatible with common small-tool holders and collets. For steels with tensile up to 800 N, a recommended feed of 0.08 mm/rev provides a good balance between cutting load and surface finish. Supplied without protective countersink, the tool is intended for immediate centring operations; ensure correct clamping of the 3.15 mm shank to avoid runout. These clear parameters support predictable cycle times and straightforward process documentation.

FAQ

What materials is the centre drill suitable for? The TECWERK centre drill is suitable for high-strength steels, steel castings, grey and hard cast iron, manganese-hardened steels, CrNi stainless steels, aluminium and other non‑ferrous metals, plus fibre-reinforced plastics and duroplastics.

What are the key dimensions and holder requirements? The tool has a 1.00 mm diameter, 31.5 mm overall length and a 3.15 mm shank; a secure 3.15 mm collet or holder is recommended to avoid runout with this small-diameter tool.

Is a protective countersink included? This version is supplied without a protective countersink; the geometry is optimised for direct centring operations rather than an additional protection feature.

What feed rate is recommended for steel? For steels with tensile strength up to 800 N, a feed of 0.08 mm/rev is recommended for stable cutting and good surface quality when using the TECWERK centre drill.

Which standards does the tool conform to? The tool follows DIN 333 Form A geometry for centre drills and is suitable for producing centring holes according to DIN 332.
