TECWERK centre drill DIN 333 Form A — 4 mm HSS, 60° countersink

The TECWERK centre drill DIN 333 Form A 4 mm is a compact tool designed for producing accurate centre holes to DIN 332, providing a secure starting point for turning and drilling operations in general metalworking applications.

• HSS centre drill, DIN 333 Form A
• 60° countersink angle for standard centre holes
• Suitable for general-purpose centre drilling
• Feed 0.03 mm/rev in steel up to 800 N

Accurate starts that comply with industry standards

The tool is built to create precise centre holes that meet the dimensions and angles specified by common workshop standards. Thanks to the DIN 333 Form A geometry and the 60° countersink, the drill produces a clean, constraint-fitting seat for live centres or centre drills used in turning operations, which improves concentricity and reduces subsequent run-out. This consistency supports higher first-pass quality and fewer reworks in serial and single-part production.

Durable HSS construction for stable performance

Manufactured from HSS, the drill offers a balance of toughness and wear resistance appropriate for routine metalworking tasks. The material choice and ground geometry deliver a long service life under typical workshop conditions and permit a controlled feed of 0.03 mm/rev when machining steel up to 800 N, ensuring consistent hole form and repeatable results. Such predictability reduces set-up time and contributes to process efficiency across batches.

Form A geometry for clean, centred hole formation

The Form A profile provides a short pilot followed by a 60° countersink, enabling reliable centre depressions without the need for additional pilot countersinking. This reduces an extra machining step and simplifies fixture setups. The orientation specified (right-hand cutting) aligns with standard drilling spindles and chucks, making integration into existing workflows straightforward and minimising operator adjustment.

Easy integration into workshop routines and quality chains

Designed for general-purpose use, the tool fits common drilling and turning preparations, making it suitable for maintenance shops, toolrooms and production lines. The robust construction and standard-compliant geometry support repetitive use and consistent inspection results, fostering dependable quality control. When paired with routine inspection and proper speeds/feeds, the drill helps maintain steady throughput and reduces uncertainty at the start of each machining operation.
