NC centre drill 6 mm – HSS‑Co, 90° point – TECWERK

A NC centre drill 6 mm designed for position-accurate pre‑drilling and simultaneous centring and chamfering on NC machines and drill heads

• HSS‑Co construction for higher wear resistance
• DIN 1835‑A cylindrical shank for secure clamping
• 90° point for centring and chamfering in one pass
• Diameter tolerance h8 for consistent hole accuracy

Precision, where it matters most

The tool provides a dependable method for producing accurate starts for subsequent drilling or threading. Made from HSS‑Co, the pre‑drill resists heat and maintains edge stability under load, which reduces burr formation and the need for secondary operations. The 6 mm nominal diameter with h8 tolerance supports repeatable hole locations, particularly valuable in batch production and automated NC machining centres. By ensuring a correct initial centre, downstream processes run more smoothly and scrap rates fall.

Robust shank standard for reliable toolholding

With a DIN 1835‑A cylindrical shank, the drill seats securely in standard tool holders and arbors, preventing axial play during high‑speed indexing or heavy feed. The fixed shank geometry simplifies tool changes and keeps concentricity within tight limits, enhancing overall process stability. The cobalt‑alloyed high‑speed steel core improves resistance to softening at elevated temperatures, making the component suitable for continuous runs on modern production equipment.

Optimised geometry for reduced cycle time

The 90° point angle and right‑hand cutting geometry enable centring and a soft chamfer in a single pass, which cuts cycle time by avoiding separate chamfering steps. Recommended feed for general steel conditions up to 800 N is 0.05 mm/rev, a parameter that balances material engagement with tool life. The 16 mm spiral length and 66 mm overall length provide sufficient flute depth for chip evacuation while maintaining rigidity for accurate positioning.

Typical uses and practical benefits

Designed for NC machines and drill heads, the spotting tool excels when precise hole starts are required before thread tapping or deep drilling. It is particularly useful for preparing threaded holes where centring and deburring in a single operation reduce handling. The tool’s combination of standard shank, cobalt HSS material and compact geometry makes it an efficient choice for workshops seeking consistent results without complex tool setups.

FAQ

What is the primary application of this centre drill?
The TECWERK NC centre drill (SKU 2000860106NW) is intended for position‑accurate spotting and chamfering on NC machines and drill heads, providing a reliable start for subsequent drilling or tapping operations.

Which material is the tool made from and what are the benefits?
Manufactured from HSS‑Co (cobalt high‑speed steel), the tool offers better heat resistance and edge retention than standard HSS, extending life under demanding production feeds and temperatures.

Will the shank fit standard tool holders?
Yes — the DIN 1835‑A cylindrical shank is compatible with holders and arbors designed to that standard, ensuring secure clamping and good concentricity.

What cutting parameters are recommended?
A feed of 0.05 mm/rev in steel up to 800 N is given as a guideline; the 90° point and right‑hand cutting geometry support combined centring and chamfering in one pass.

How precise is the drill diameter?
The nominal 6 mm diameter is held to an h8 tolerance class, suitable for repeatable positioning and consistent hole starts.
