TECWERK Centre Drill DIN 333 Form A, HSS‑Co, Ø1 mm

The TECWERK Centre Drill DIN 333 Form A is a right‑hand cutting centre drill intended for producing DIN‑compliant centre holes and light countersinks in high‑strength and corrosion‑resistant steels.

• HSS‑Co for improved heat resistance
• DIN 333 Form A geometry for standard centre holes
• 60° countersink angle for DIN‑compatible centres
• Suitable for high‑strength and CrNi steels

Precision drilling for high‑strength components

Engineered for demanding applications, this centre drill uses HSS‑Co to offer improved hot hardness and wear resistance during high‑load operations. The specified 60° countersink angle ensures compliance with standard centre‑hole geometry, which reduces alignment errors in subsequent turning or drilling operations. For materials with tensile strengths above 800 N/mm² and for CrNi steels, the tool maintains cutting stability and helps prevent material work hardening, thereby lowering the risk of premature tool failure and rework.

Consistent geometry reduces secondary operations

The DIN 333 Form A profile provides a robust pilot and a precise countersink in a single operation, eliminating the need for an additional protective countersink. This dual action preserves concentricity for follow‑up machining and shortens process chains on the shop floor. With a recommended feed of 0.02 mm/rev in steels up to 800 N, the geometry balances material removal and tool life, delivering repeatable centre holes that simplify setup and fixture alignment.

Efficient operation for routine workshop use

Designed for reliable performance in serial and job‑shop environments, the centre drill's right‑hand cutting direction complements common spindle rotations and clamping arrangements. The tool is suitable for stainless, acid‑ and heat‑resistant CrNi steels, enabling consistent starts for turning and drilling cycles. By combining standardised geometry with a wear‑resistant alloy, the instrument helps to streamline operations, reduce cycle times and maintain part quality across production runs.

FAQ

What materials can this centre drill machine?
The TECWERK centre drill is suitable for high‑strength materials and specifically for CrNi stainless steels; it is designed for applications where tensile strengths exceed 800 N/mm².

Is the countersink angle compatible with DIN standards?
Yes, the tool uses a 60° countersink angle to produce centre holes that conform to DIN 332 when no protective countersink is required.

What feed rate is recommended for steel?
A feed of 0.02 mm/rev is advised for machining steel up to 800 N; this setting balances efficient cutting with tool life for the TECWERK centre drill.

Does the tool require a separate protective countersink?
No separate protective countersink is necessary: the DIN 333 Form A profile is intended to create the required centre geometry without an additional protective operation.

What is the SKU for ordering and reference?
Please refer to SKU 2000861577NW when ordering the TECWERK centre drill to ensure accurate product identification.
