TECWERK NC spot drill D20 mm — solid carbide, 90°

The TECWERK NC spot drill D20 mm is a purpose‑built centre and spot drilling tool for NC machines and drilling rigs, enabling position‑accurate starts and combined centring and chamfering in a single pass.

• Solid carbide (VHM) for high wear resistance
• Cylinder shank to DIN 6535‑HA for secure clamping
• 90° point for rapid centring and chamfering
• Suitable for high‑strength steels and stainless

Faster, position‑accurate starts that reduce cycle time

The combination of a 90° point and a tool geometry designed for positions‑accurate drilling reduces time spent on setup and rework. As a dedicated spot‑drilling tool, it creates a precise entry that improves subsequent drilling and tapping accuracy, cutting rejected parts and secondary operations. The robust geometry means fewer tool changes and fewer alignment steps on CNC lathes and machining centres, helping to streamline production sequences and increase usable spindle time.

Long tool life and broad material compatibility

Manufactured from solid carbide (VHM), the tool offers high resistance to abrasive wear and retains cutting edges under elevated loads. This makes it especially suitable for high‑strength steels, cast steel, grey cast iron, stainless steels and a range of non‑ferrous metals. The inherent stiffness of the material reduces the risk of chipping when used within recommended parameters, delivering consistent hole quality across mixed production batches and extending the interval between regrinds or replacements.

Secure clamping and machine integration for reliable results

The cylinder shank to DIN 6535‑HA standard provides a reliable interface for toolholders and chucks, ensuring concentricity and minimising run‑out. Right‑hand cutting geometry enhances process stability on conventional spindle directions, while the shank standard supports straightforward integration into existing tool magazines and automatic tool changers. For shops aiming to keep spindle tolerance and clamping precision under control, this interface markedly reduces vibrations and improves repeatability.

Practical cutting data and process guidance for predictable performance

For reference in process planning, the tool is optimised for a feed of 0.16 mm/rev in steel up to a cutting force of 800 N; this figure helps in estimating cycle times and tool life when programming NC operations. When used as intended for spot drilling and chamfering in one pass, it reduces the need for separate countersinking operations and delivers consistent chamfer geometry ready for subsequent tapping. Such predictable data supports faster setup decisions and more reliable throughput in serial production.

FAQ

What materials can this spot drill machine effectively?
The TECWERK NC spot drill is designed for high‑strength steels, cast steel, grey cast iron, stainless steels and non‑ferrous metals, delivering robust edge retention due to its solid carbide construction.

Can the tool centre and chamfer a tapped hole in a single operation?
Yes. The tool geometry enables combined centring and chamfering in one pass, removing the need for a separate countersinking step when preparing for tapping.

What shank standard does the tool use and why is that important?
It features a cylinder shank to DIN 6535‑HA, which ensures consistent clamping and concentricity in standard toolholders and chucks, improving repeatability on NC machines.

What feed rate is recommended for steel applications?
For steel with cutting forces up to 800 N, the indicated feed is 0.16 mm/rev, a practical datum for programming NC cycles and estimating tool life under typical conditions.

Which SKU should be referenced when ordering or requesting spare tooling information?
Reference SKU 2000865809NW when enquiring about the TECWERK NC spot drill to ensure the correct item is supplied.
