NC Spot Drill D8 mm HSS‑Co TiN 90° — TECWERK spot drill for NC machines

A NC Spot Drill D8 mm HSS‑Co TiN 90° engineered for fast, position‑accurate centre‑drilling and chamfering on NC machines and drilling centres

• HSS‑Co construction with TiN coating
• 8 mm diameter, 90° spot drill
• Cylinder shank to DIN 1835‑A
• Centres and chamfers threaded holes in one pass

Faster, more consistent centre‑drilling through material design

The combination of HSS‑Co substrate and a TiN surface layer delivers improved heat resistance and abrasion protection compared with standard high‑speed steels. This means longer in‑service life and more consistent hole quality across production runs. Specified as a right‑hand cutting tool with a cylinder shank to DIN 1835‑A, the tool ensures secure clamping in standard collet systems and minimises run‑out, which directly improves repeatability and reduces scrap in serial machining. For shops running mixed batches, this material specification supports sustained performance under elevated temperatures encountered during rapid NC operations.

Combine centring and chamfering to reduce cycle time

Designed to perform centre‑drilling and chamfering of threaded holes in a single pass, the tool reduces handling and repositioning steps. The axial geometry with a 90° point angle provides reliable engagement and accurate positioning for subsequent drilling or tapping operations. A recommended machining parameter supplied with the tool indicates a feed of 0.07 mm/rev in steel up to 800 N, which offers a balance between tool life and machining speed. Translating cycle reduction into throughput gains, workshops can shorten lead times and increase part output without adding complexity to the machining sequence.

Integration, handling and typical applications for dependable results

The tool is intended for use on NC machines and drilling centres where accuracy and repeatability are priorities. The cylinder shank to DIN standard simplifies integration into existing toolholders and enables fast change‑overs in production cells. The right‑hand cutting characteristic and the TiN coating reduce built‑up edge and help achieve cleaner chamfers, which lowers rework rates and improves surface preparation for threading. Typical users are industrial production departments, jobbing toolrooms and maintenance workshops that require a compact, robust solution for position‑sensitive pre‑drilling and countersinking operations.

FAQ

Is this tool suitable for use on CNC/NC drilling centres?
The TECWERK NC Spot Drill D8 mm HSS‑Co TiN 90° is designed specifically for NC machines and drilling centres, offering the shank and geometry required for stable, position‑accurate operation.

Which materials can be machined with this spot drill?
With its HSS‑Co construction and TiN coating, the tool is suitable for general steel machining; the specification notes a feed of 0.07 mm/rev for steel up to 800 N, which guides safe operation on common steel grades.

What clamping systems are compatible with the shank?
The cylinder shank conforms to DIN 1835‑A, so the spot drill fits standard collets and holders that accept DIN‑A cylindrical shanks for secure mounting.

Can the tool centre and chamfer in a single pass for threaded holes?
Yes — the tool is intended to centre and chamfer threaded holes in one operation, reducing setup steps and improving cycle efficiency for subsequent tapping.

How does the TiN coating benefit everyday use?
The TiN wear layer reduces friction and built‑up edge, improving surface finish and extending tool life under continuous NC operation with frequent contact and heat generation.
