TECWERK Centre Drill DIN 333 Form A, 1.00 mm — HSS‑Co, 60°

The TECWERK centre drill DIN 333 Form A is a short centre drill designed to produce precise centre holes for subsequent turning and drilling operations in high‑strength and corrosion‑resistant materials.

• HSS‑Co for elevated heat resistance
• DIN 333 Form A geometry with 60° tip
• Suitable for materials >800 N/mm² and CrNi steels
• Shank Ø 3.15 mm, overall length 31.5 mm

Accurate centring in demanding materials

The short‑length centre drill combines a HSS‑Co alloy with a 60° point to deliver reliable centring even when machining rust-, acid- and heat‑resistant CrNi steels and other materials with tensile strength above 800 N/mm². Cobalt‑alloyed high‑speed steel increases red‑hardness and wear resistance, which reduces tool wear under higher temperatures; this translates into fewer tool changes and more consistent hole quality in production runs. The tool is engineered for producing centre holes that meet DIN specifications, ensuring repeatable starting points for subsequent machining.

Geometry engineered for repeatable results

The DIN 333 Form A geometry and right‑hand cutting design produce a clean, well‑defined centre bore compatible with follow‑up drills and live‑centres. The 60° point angle is the industry standard for centre holes per DIN 332, which helps maintain concentricity and minimise runout during turning and drilling. The specification "without protective countersink" indicates that the drill forms the centre as required for standard clamping and live‑centre seating, eliminating the need for secondary countersinking operations and saving cycle time.

Practical compatibility and operational benefits

With a shank diameter of 3.15 mm and an overall length of 31.5 mm, the centre drill fits common small‑toolholders and collets used in toolrooms and production lathes. The recommended feed in steel up to 800 N is 0.02 mm/rev, offering a practical starting point for machining parameters that balance tool life and hole quality. Supplied in packs of 5, the tool is suitable for small batch production and workshop restocking, supporting a streamlined workflow with fewer interruptions for reordering.

FAQ

What materials is this centre drill suitable for?
The TECWERK centre drill DIN 333 Form A (SKU 2000861577NW) is specified for materials with tensile strength above 800 N/mm² and for rust‑, acid‑ and heat‑resistant CrNi steels.

What is the point angle and why does it matter?
The tool has a 60° point angle, the standard for centre holes per DIN 332, which ensures correct seating for live centres and accurate positioning for subsequent drilling or turning.

What feed rate is recommended for steel?
A feed of 0.02 mm per revolution is documented for steel up to 800 N, providing a practical balance between tool life and hole quality.

Which holders are compatible with the shank?
The 3.15 mm shank diameter is compatible with common small collets and toolholders used in lathes and drill chucks for workshop and light‑production environments.

How is the product supplied?
The centre drill is supplied in a packaging unit of 5 pieces under SKU 2000861577NW.
