TECWERK centre drill DIN 333 Form A, Ø 3.15 mm — HSS‑Co, extra‑long

TECWERK centre drill DIN 333 Form A Ø 3.15 mm HSS‑Co is a precision centring tool designed for creating clean centre holes to DIN 332 without protective countersink; ideal for general workshop and production use.

• HSS‑Co material for higher hot hardness
• DIN 333 Form A standard compliance
• 60° centre point for accurate positioning
• Extra‑long design for deep centring

Durable material and standardised geometry for consistent results

The HSS‑Co composition gives the tool improved red‑hardness compared with standard high‑speed steels, which maintains cutting edge stability under elevated temperatures. Combined with the DIN 333 Form A geometry and a 60° tip angle, this centre drill produces reproducible centring holes that comply with established machining standards. The standardised shape reduces setup variability and supports reliable downstream drilling and turning operations, enhancing process repeatability on shop floors.

Practical performance data for machining workflows

Specified for a feed of 0.03 mm per revolution in steel up to 800 N, the tool offers a clear reference for programming and feed selection in routine centring tasks. The Ø 3.15 mm diameter and defined tip angle ensure accurate initial positioning for subsequent drill or lathe operations, thereby reducing run‑out and improving tool life of secondary cutters. The feed figure provides a conservative baseline to achieve clean chip formation in many common steels without overloading the cutting edge.

Design advantages that simplify deep‑reach centring

The extra‑long construction extends the reach for centring operations in recessed or awkward components, while the right‑hand cutting direction suits conventional spindle rotation. This elongated form helps avoid repeated set‑ups and enables centring at depth with fewer tool changes. The balanced combination of material and length supports longer service intervals and promotes steady cutting behaviour in serial production and one‑off workshop tasks alike.

Where and how this centre drill fits into the workflow

As a general‑purpose centring solution, the instrument is intended for use wherever a compliant centre hole is required before drilling, reaming or turning. Its DIN 333 conformity makes it easy to standardise across jigs and fixtures, and the robust HSS‑Co alloy gives confidence in everyday workshop conditions. For tasks requiring deeper entry points or restricted access, the extra‑long variant reduces handling complexity and contributes to smoother machining cycles.

FAQ

What does DIN 333 Form A imply for centring quality?
DIN 333 Form A specifies the geometry and tip angle of the centre drill; the TECWERK centre drill conforms to this form, ensuring standardised, repeatable centre holes suitable for subsequent machining.

Is the tool suitable for deep centring tasks?
Yes, the extra‑long design provides extended reach for deeper centring operations, reducing the need for multiple set‑ups when working on recessed components.

What feed should be used in steel?
The specified feed for steel up to 800 N is 0.03 mm per revolution, which offers a reliable starting point for clean chip formation and consistent hole quality.

What advantages does HSS‑Co offer compared with standard HSS?
HSS‑Co delivers higher red‑hardness and better wear resistance at elevated temperatures, extending edge life under demanding cutting conditions and supporting stable centring performance.

How is the item identified for ordering?
