TECWERK centre drill DIN 333 Form A, HSS‑Co, Ø 1.25 mm

The TECWERK centre drill DIN 333 Form A is a compact centre‑drill for producing DIN‑compliant centre holes in high‑strength and corrosion‑resistant steels, designed for reliable positioning and repeatable pre‑drilling in demanding shop environments

• HSS‑Co construction for high strength
• DIN 333 Form A specification
• 60° centre angle for accurate centring

Consistent centring for high‑strength materials

This centre‑drill is made from HSS‑Co, an alloyed high‑speed steel that combines hardness with toughness for demanding cutting tasks. The tool is specified for materials with a tensile strength above 800 N/mm² and for CrNi steels that are stainless, acid‑ and heat‑resistant. The 60° centring angle and the Form A geometry ensure stable initial engagement and reduce the risk of walking, delivering precise centre holes essential for subsequent drilling or turning operations.

Geometry and dimensions optimised for workshop repeatability

Engineered to DIN 333 with a total length of 31.5 mm and a slender Ø 1.25 mm point, the tool provides a compact footprint that suits toolholders and small chucks. The 3.15 mm shank is sized for secure clamping while maintaining concentricity. Together, these dimensions support repeatable positioning, reducing setup time and improving first‑pass accuracy on the workpiece.

Cutting performance tuned for efficiency

With a right‑hand cutting direction and a recommended feed of 0.02 mm/rev in steel up to 800 N, the drill balances low cutting forces with clean formation of the centre dimple. The cobalt‑alloyed substrate sustains edge integrity at elevated contact stresses, enabling longer tool life and fewer interruptions in production. For workshops aiming to streamline workflow, this combination offers a measurable increase in process reliability.

Practical use and handling in production environments

Supplied without a protective countersink, the tool is intended specifically for manufacturing centre holes to DIN 332 and pairs well with standard centre‑drilling sequences. Packaged in sets of 5 units, it is suitable for small series and routine maintenance inventories.
