TECWERK NC spot drill D.20mm, HSS‑Co, TiN, 90°

The TECWERK NC spot drill D.20mm HSS‑Co TiN 90° is a purpose‑built spot drill for NC machines and boring mills, engineered to centre and chamfer thread holes in a single operation for consistent thread starts

• HSS‑Co for high wear resistance
• TiN coating extends tool life
• Cylindrical shank to DIN 1835‑A
• Centring and chamfering in one pass

Faster thread starts through accurate spot‑drilling

The tool enables positional spot‑drilling with a defined 90° point, which reduces wander when starting taps or drills and shortens set‑up time. By providing a precise centre in one operation, the component requires fewer re‑clamps and corrections, improving throughput on batch runs. The specified machining parameter 0.12 mm/rev (feed in steel up to 800 N) indicates the recommended feed per revolution under rated cutting forces, helping to define stable cutting conditions and predictable cycle times.

Durable materials and a low‑friction coating for longer service life

Constructed from HSS‑Co (cobalt high‑speed steel) and finished with a TiN coating, the cutter combines a tough substrate with a hard, low‑friction surface to resist abrasive wear and reduce built‑up edge. This material combination keeps the cutting geometry sharper for longer and supports repeatable performance when producing series parts. The cylindrical shank to DIN 1835‑A ensures secure clamping and concentricity in standard toolholders, contributing directly to tool life and process stability.

Designed for smooth integration into CNC workflows

Right‑hand cutting geometry and a standard shank format mean straightforward integration into NC machines and boring mills without special adaptors. The ability to perform centring and chamfering of thread holes in one pass minimises tool changes and handling steps, resulting in fewer machine cycles per part and lower process complexity. For production environments where consistent thread starts and reduced operator intervention are priorities, this spot drill supports leaner machining sequences and improved first‑pass yield.

FAQ

Which machines is this spot drill suitable for?
The TECWERK NC spot drill is designed primarily for NC machines and boring mills and is suitable for integration into standard toolholders thanks to its cylindrical shank to DIN 1835‑A.

What does HSS‑Co mean and why is it used here?
HSS‑Co denotes cobalt‑alloyed high‑speed steel; the cobalt content improves hot hardness and toughness, making the cutter suitable for repeated starts and for withstanding higher cutting temperatures during precise spot‑drilling.

How does the TiN coating benefit the tool?
The TiN coating reduces friction and improves wear resistance; on the TECWERK spot drill this helps maintain cutting edge geometry longer and supports consistent centring over extended production runs.

Can the tool centre and chamfer thread holes in one operation?
Yes — the design of the spot drill allows centring and light chamfering of thread holes in a single pass, reducing the number of setups and tool changes required for threaded hole preparation.

What feed rate is recommended for steel workpieces?
For steel under cutting forces up to 800 N, the recommended feed is 0.12 mm per revolution, which balances stable cutting with efficient material removal for accurate spot‑drilling.
