TECWERK Centre Drill DIN 333 Form A, 3.15 mm — HSS, TiN-coated

A TECWERK centre drill DIN 333 Form A designed for reliable centring and pilot seating in metalworking and machining applications.

• HSS base material with TiN coating
• DIN 333 Form A geometry, 60° countersink
• Right-hand cutting for conventional drills
• Feed recommendation in steel: 0.03 mm/rev

Improve initial hole accuracy with positive geometry and coating

The combination of the DIN 333 Form A geometry and a 60° countersink angle ensures clean, repeatable centre holes that guide subsequent drills precisely. This characteristic reduces runout at the start of a bore and minimises the need for corrective passes. The tool’s high-speed steel (HSS) body provides toughness under shock loads, while the TiN coating lowers friction and enhances wear resistance, extending useful life. For operations where initial centring determines final tolerance, this design delivers measurable gains in process reliability.

Boost throughput with a clear feed recommendation and conventional cutting

Engineered for standard machining workflows, the centre drill is right-hand cutting and suited to conventional spindle directions. A recommended feed in steel up to 800 N of 0.03 mm/rev provides a practical starting point for many workshop setups and supports consistent hole formation without excessive tool stress. By following this parameter, cycle times can be stabilised and scrap rates reduced, yielding a better cost-per-part ratio. The integrated countersink geometry also permits producing centre holes per DIN 332 without an additional pre-countersinking step, saving time on repetitive routines.

Durable, general-purpose solution for everyday workshop use

This centre drill combines robustness and versatility for general machining tasks. The TiN coating enhances surface hardness and reduces sticking during chip evacuation, while the HSS substrate maintains resistance to chipping in interrupted cuts. The result is a tool that performs reliably across a range of standard materials encountered in production and repair environments. For workshops seeking to standardise tooling without compromising on start-hole quality, this product provides a compact and dependable option that supports consistent part quality.

FAQ

What is the primary application of this centre drill?
The centre drill is intended for producing precise centre holes and pilot seating in metalworking, enabling accurate starts for drilling operations in accordance with DIN 332 where no pre-countersinking is required.

How does the TiN coating benefit performance?
The TiN coating on the TECWERK centre drill increases surface hardness, reduces friction during entry, and improves wear resistance, contributing to longer tool life and more consistent centring.

What feed rate should be used when drilling steel?
A practical guideline is a feed of 0.03 mm per revolution in steel up to 800 N, which balances cutting engagement and tool durability for reliable centre-hole formation.

Is the tool suitable for conventional machine spindles?
Yes; the centre drill features right-hand cutting geometry, making it compatible with standard spindle rotation directions and typical workshop machines.
