TECWERK NC spot drill D 8 mm — HSS‑Co, 90° tip, DIN 1835‑A shank

TECWERK NC spot drill D 8 mm HSS‑Co — a position‑accurate starting drill for NC machines and boring mills, designed to centre and chamfer thread holes in a single pass.

• HSS‑Co for high temperature resistance
• Cylindrical shank DIN 1835‑A
• 90° tip for precise centring and chamfering
• Feed in steel up to 800 N: 0.07 mm/rev

Reduce cycle time with accurate single‑pass centring and chamfering

The tool delivers position‑accurate starts by combining a precise tip geometry with robust material, so one operation achieves both centring and chamfering. This removes a separate centring step and reduces handling between operations, resulting in measurable time savings on repetitive NC and boring‑mill programmes. The 90° tip is optimised to create a clear, well‑defined seat for subsequent drilling or tapping, lowering the risk of runout and rework.

Durable construction for extended tool life under production conditions

Manufactured from HSS‑Co, the drill offers improved red‑hardness and wear resistance compared with conventional high‑speed steels. The cobalt alloy resists heat buildup during intermittent spotting cycles and maintains cutting geometry over longer runs, which supports stable hole quality and fewer tool changes. The combination of material and geometry means consistent results on interrupted cuts typical of workholding setups in series production.

Compatibility and secure holding for CNC tool systems

A DIN 1835‑A cylindrical shank ensures simple, repeatable clamping in standard drill chucks and tool holders, while the right‑hand cutting configuration matches conventional spindle rotations. The nominal 8 mm diameter and defined tip angle make the tool straightforward to program for feed and plunge routines; the specified feed capacity of 0.07 mm/rev in steel up to 800 N gives a reliable baseline for cycle planning. These characteristics make the design suitable for both small batch shops and integrated production lines.

Practical benefits for workshop efficiency and process reliability

Using a dedicated spot drill like this reduces downstream scrap and improves thread start consistency when preparing tapped holes. The tool is supplied as a single unit (packaging unit 1), simplifying stockkeeping for essential starter tools. Clear, standardised dimensions and documented feed guidance support process documentation and quality control efforts, helping to embed repeatable setups across machines and operators.

FAQ

What is the primary use of this spot drill?
The TECWERK NC spot drill D 8 mm is designed for position‑accurate spot drilling and simultaneous centring and chamfering of thread holes on NC machines and boring mills.

Which material is the tool made from and why does it matter?
Made from HSS‑Co, the tool maintains cutting performance at higher temperatures and offers superior wear resistance compared with standard high‑speed steel, supporting longer life in production use.

How should the shank be clamped?
The DIN 1835‑A cylindrical shank is intended for secure clamping in standard drill chucks and compatible tool holders to ensure concentricity during spotting operations.

What feed rate is recommended for steel?
A feed of 0.07 mm/rev is specified for steel when cutting under forces up to 800 N; this provides a reliable starting point for programming and process planning.

Does the tool support both centring and chamfering in one operation?
Yes — the geometry of the TECWERK NC spot drill D 8 mm is configured to centre and chamfer thread holes in a single pass, reducing cycle time and handling.
