NC Spot Drill Ø4 mm, HSS‑Co, TiN, 90° by TECWERK

The NC Spot Drill Ø4 mm, HSS‑Co, TiN, 90° (TECWERK) is a compact NC centre drill designed for position‑accurate starting holes, centring and chamfering of tapped holes in a single operation on machining centres and boring mills.

• HSS‑Co for improved wear resistance
• TiN coating for longer tool life
• DIN 1835‑A cylindrical shank
• 90° point angle for accurate centring
• Optimised for NC machines and boring mills

High-precision geometry for reliable positioning

The compact starting drill delivers position‑accurate spot drilling and is especially suitable where the initial hole must be exact before subsequent drilling or tapping. Constructed from HSS‑Co, the tool combines toughness and cutting performance, while the 90° point angle supports precise centring and reliable seating of the following tool. The combination of geometry and material reduces the risk of wandering at entry and improves hole quality on thin or delicate workpieces.

Designed for efficient integration into NC workflows

With a DIN 1835‑A cylindrical shank, the tool fits standard toolholders for machining centres and boring mills, enabling rapid tool changes and consistent clamping. The right‑hand cutting design and TiN coating reduce friction and extend lifetime under high spindle speeds, making the drill an efficient choice for repetitive NC operations. Because the tool performs centring and chamfering in one pass, cycle times are shortened and setup complexity is reduced.

Practical machinability and recommended feed

The drill is specified for controlled feeds in steel: feed in steel up to 800 N: 0.03 mm/rev, which offers a balance between chip formation and tool life in common steels. The feed recommendation supports predictable performance when used as a starting drill prior to pilot or thread drilling. The tool’s right‑hand cutting action and solid geometry are suitable for standard workshop cutting conditions on production machines and individual repair jobs alike.

Durability, handling and application range

A TiN coating provides a harder, low‑friction surface that improves wear resistance and resists built‑up edge formation, while the HSS‑Co base material maintains edge stability. The tool is intended for spot drilling, centring and chamfering of tapped holes in one operation on NC machines and boring mills, offering a practical solution for repetitive tasks where consistent quality is required. The simple cylindrical shank supports established tool change routines in industrial settings.

FAQ

What materials can this spot drill be used on?
The TECWERK NC spot drill (SKU 2000861384NW) is specified for use in general steel applications with a recommended feed of 0.03 mm/rev under the stated conditions; suitability for other materials depends on machine setup and cutting data.

How does the TiN coating benefit the tool?
The TiN coating on this starting drill reduces friction, improves wear resistance and helps maintain cutting performance under prolonged NC operation.

Is the shank compatible with standard NC toolholders?
Yes, the cylindrical shank conforms to DIN 1835‑A, making it compatible with machine tool adapters and holders that accept this standard.

Can the tool perform centring and chamfering in a single pass?
The tool is designed to centre and chamfer threaded hole entries in one operation, reducing cycle time and simplifying setup on machining centres and boring mills.
