Centre drill DIN 333 Form A, 1.6 mm – HSS TiN (TECWERK)

The Centre drill DIN 333 Form A 1.6 mm is a TiN-coated HSS centre drill designed for precise preparation of 60° centre holes in general workshop and industrial drilling operations.

• Centre drill DIN 333 Form A
• HSS substrate with TiN coating
• Countersink angle 60°
• 4 mm shank, right-hand cutting

Consistent centre-hole geometry for reliable downstream operations

The geometrically defined 60° countersink ensures that the prepared centre holes meet the expectations of conventional turning and drilling workflows, enabling repeatable seating and run-out control. Manufactured to DIN 333 Form A, the tool provides a standardised interface for subsequent steps, which reduces setup time and the need for reworking. The right-hand cutting configuration matches most machine tool spindles and clamping arrangements, promoting smoother chip evacuation and predictable tool behaviour.

Longer service life through coating and material selection

A HSS substrate combined with a TiN coating delivers a balance between toughness and surface hardness. The hard titanium nitride layer improves wear resistance and reduces built-up edge formation, which extends tool life under typical centre-drilling loads and lowers tooling costs over time. For applications in mixed workshops where tool changes interrupt production, this combination delivers improved longevity without sacrificing edge stability.

Easy integration and versatile mounting

With a 4 mm shank, the drill integrates with common collets and small chucks used in benchtop and production machinery. The compact nominal diameter of 1.6 mm is suitable for precise centring on small components and pre-drilling operations, while the tool’s compliance with DIN 333 simplifies inventory and replacement planning. The standardised form factor supports rapid tool exchange, limiting machine downtime and fostering a predictable production flow.

Practical machining guidance for efficient results

For typical steels up to an estimated cutting resistance of 800 N, a recommended feed is approximately 0.02 mm per revolution, which balances cutting forces and surface finish when preparing the centre. The TiN coating lowers friction at the cutting edges, permitting stable operation at commonly used spindle speeds for small-diameter centre drills. When preparing workpieces for turning or drilling, ensuring the workpiece is securely clamped and that coolant or appropriate lubrication is applied will help achieve consistent centring and extend tool life.

FAQ

What is the recommended feed rate for centre-drilling in steel?
For steels with cutting resistance up to roughly 800 N, the recommended feed for this TECWERK centre drill is approximately 0.02 mm per revolution to balance tool life and hole quality.

Which shank sizes and clamping systems are compatible?
The tool features a 4 mm shank, suitable for standard small chucks and collets used in benchtop machines and production centres where compact centre drills are required.

How does the TiN coating affect performance?
The TiN coating increases surface hardness and reduces friction at the cutting edges, resulting in improved wear resistance and more stable cutting behaviour during centre-hole preparation.

Is this centre drill suitable for precision turning set-ups?
Yes, the standardised 60° geometry and conformity with DIN 333 Form A make it suitable for preparing centre holes that provide reliable seating and accurate alignment for turning operations.

What size of centre hole does the 1.6 mm nominal diameter produce?
The 1.6 mm nominal diameter produces a small, precisely located centre recess appropriate for subsequent drilling or for mounting on centre points in smaller workpieces.
