TECWERK centre drill DIN 333 Form A Ø 3.15 mm HSS left-hand cut — 60° centring tip

A TECWERK centre drill (DIN 333, Form A, Ø 3.15 mm, HSS, left-hand cut) engineered for precise centre-hole production in general workshop and light industrial applications.

• HSS construction for durability and sharpness
• DIN 333 Form A geometry, 60° centring tip
• Left-hand cutting for chip evacuation and reaming
• Feed in steel up to 800 N: 0.03 mm/rev

Accurate starts for turning and drilling setups

The Form A geometry with a 60° tip ensures that centre holes are formed consistently to the relevant standard, allowing reliable chucking and reduced run-out in subsequent turning operations. Made from HSS, the tool retains cutting edge integrity during repeated use and resharpening cycles. The nominal diameter of 3.15 mm produces compact, precise centres suitable for small to medium workpieces; the controlled geometry reduces the need for corrective finishing and supports predictable positioning on the lathe or drilling machine.

Built for dependable workshop performance

A sturdy 8 mm shank and an overall length of 50 mm provide rigidity and ease of handling in standard collets and three-jaw chucks. The left-hand cut assists chip control in specific machining sequences, and the specified feed of 0.03 mm/rev in steel up to 800 N gives a reliable starting parameter for process planning. Because the material is HSS, the tool offers a balance between toughness and hardness, making it suitable for everyday centring tasks without fragile performance under moderate loads.

Seamless integration into production routines

The DIN-compliant design simplifies tool selection and inventory management across multiple workstations; compatibility with common holders and quick-change systems shortens setup time. As the tool is intended for general use, it adapts well to a range of ferrous materials when used with the recommended feed. Clear technical parameters enable straightforward process documentation and repeatability, which supports quality control procedures and reduces scrap due to incorrect centring.

Suitable choice for precision-minded workshops

For professional workshops aiming to democratise precision without compromise, this centre drill delivers dependable centring, straightforward resharpening and consistent results across batches. The compact geometry and proven material choice reduce downtime and maintain dimensional accuracy for subsequent operations, offering a practical balance of performance and economy for day-to-day metrology and turning preparations.
