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

The NC spot drill D 20mm HSS‑Co 90° is a right‑hand cutting tool for positions‑accurate spot drilling and single‑pass centring and chamfering on NC machines and boring mills

• HSS‑Co construction for improved wear resistance
• 90° point for reliable centring and chamfering
• Cylindrical shank to DIN 1835‑A for secure clamping

Faster production through accurate first‑pass holes

The combination of a cobalt‑alloy HSS body and a sharp 90° point reduces the need for secondary operations by producing accurately centred entry points on the first cut. In production environments this translates into shorter cycle times and fewer tool changes, because the tool both locates and deburrs the bore entry. The robust design supports reproducible results on automated equipment, lowering scrap rates and improving overall throughput.

Secure clamping for consistent concentricity

A cylindrical shank to DIN 1835‑A offers standardised, reliable retention in toolholders and chucks, which helps maintain concentricity under machining loads. The right‑hand cutting geometry stabilises chip flow and reduces chatter, delivering a steadier finish and extending service life of the cutting edge. These attributes are especially beneficial when working in series production on NC machines or when repeatability between batches is essential.

One‑operation centring and chamfering to reduce handling

Designed to perform centring and chamfering of tapped holes in a single operation, the tool removes the need for a separate chamfering step. The integrated 90° point shapes the entry chamfer while accurately locating the bore centre, simplifying set‑up routines and reducing handling time. For workshops aiming to streamline process flow, this dual‑function approach directly supports leaner machining sequences.

Controlled feed parameters for predictable results

Specified feed guidance for steel — 0.12 mm/rev at up to 800 N — provides a practical reference for achieving stable cutting conditions with this type of tool. The cobalt‑enriched high‑speed steel balances toughness and red hardness, offering good resistance to heat and abrasion under moderate feeds and speeds. When combined with proper clamping and a matched holder, the tool delivers consistent hole geometry and repeatable performance across production runs.

FAQ

What machines is this spot drill suitable for?
The TECWERK NC spot drill D 20mm HSS‑Co 90° is intended for use on NC machines and boring mills for positions‑accurate spot drilling.

Can the tool centre and chamfer tapped holes in one pass?
Yes — the 90° point is designed to perform centring and chamfering of threaded holes in a single operation, reducing handling and cycle time.

What does HSS‑Co mean and why is it used here?
HSS‑Co denotes cobalt‑alloyed high‑speed steel; this material offers improved heat and wear resistance compared with standard HSS, beneficial for the spotting and chamfering duties of this tool.

What does a shank to DIN 1835‑A signify?
A cylindrical shank to DIN 1835‑A indicates a standardised straight shank dimension and form for secure clamping in compatible holders and chucks, contributing to reliable concentricity.

What feed rate is recommended for steel?
The tool specification indicates a reference feed in steel of 0.12 mm/rev at up to 800 N, providing a guideline for stable cutting conditions.
