Centre drill DIN 333 Form A Ø1.6 mm (HSS‑Co) – extra‑long, 60° countersink (TECWERK)

The centre drill DIN 333 Form A Ø1.6 mm is an extra‑long, right‑cutting HSS‑Co tool designed to produce standard centre holes according to DIN 332 without a pilot countersink.

• HSS‑Co for enhanced wear resistance
• Extra‑long design for deep centring
• 60° countersink for standard centre holes

Precision where production tolerance matters

Manufactured to DIN 333 and executed in HSS‑Co, this centre drill delivers reproducible centring for subsequent drilling or turning operations. The combination of a fine Ø1.60 mm tip geometry and the 60° countersink angle ensures reliable guidance of the main drill and reduces runout risk. For process planners, the measurable stability of the centring operation translates into fewer rejected components and lower rework rates — a direct efficiency gain in the production chain.

Reach and stability for deeper setups

The extra‑long configuration with a 120 mm overall length addresses applications where standard short tools cannot reach; the extended reach allows centring in recessed faces and complex-fixture situations. The right‑cutting helix and robust shank diameter of 5 mm contribute to torsional stability, so the bit remains true under light feed conditions. This design reduces chatter and supports consistently accurate centre holes even when access is restricted.

Material choice and cutting data explained

Cobalt‑alloy high‑speed steel (HSS‑Co) combines hardness at elevated temperatures with toughness, making the tool suitable for repeated centring cycles in workshop and production environments. The specified feed guidance of 0.02 mm/rev in steel up to 800 N offers a practical starting point for setting machine parameters; this conservatively balanced feed promotes controlled chip formation and extends tool life. The right‑hand cutting direction matches standard machine spindles for simple integration.

Simple adoption into workshop routines

As a purpose‑built centring tool, the bit is intended for the preparation of centre holes to DIN 332 without a pilot countersink, enabling safe and accurate tailstock or live‑centre support later in the process. The compact Ø1.60 mm tip minimises material removal while providing a clear locating point for subsequent operations. For production planners and workshop managers, the tool’s familiar standard allows quick substitution into existing tool lists and tooling cabinets with minimal requalification.

FAQ

What is the primary application of this centre drill? The TECWERK centre drill DIN 333 Form A Ø1.6 mm is intended for creating standard centre holes to DIN 332, preparing components for accurate support with tailstocks or centres.

Can this tool be used for deep centring in jigs and fixtures? Yes, the extra‑long overall length of 120 mm enables centring in recessed faces and fixtures where standard tools cannot reach.

What cutting data should be used as a starting point for steel? Begin with a feed of approximately 0.02 mm per revolution in steel up to 800 N, as this promotes stable chip formation and extends tool life.

Is the material specification suitable for frequent workshop use? The HSS‑Co construction provides elevated hot hardness and toughness, making the tool suitable for repetitive centring operations in a busy workshop environment.

Does the tool require a pilot countersink for use? No; the execution is specified for centre holes without a pilot countersink and is designed to produce compliant centres per DIN 332.
