NC centre drill D10 mm (solid carbide, TiAlN, 142°) – TECWERK

The NC centre drill D10 mm (TECWERK) is a precision pilot drill for positional centring and rapid pilot drilling on NC machines and drilling centres, designed to centre and chamfer thread holes in a single pass.

• Solid carbide (VHM) with TiAlN coating
• 142° point angle for accurate centring
• Cylindrical shank to DIN 6535‑HB, h6 tolerance
• Suited for high‑strength steels and stainless

Consistent accuracy from its carbide core

The combination of solid carbide body and a low‑runout geometry delivers a stable cutting process that minimises vibration and improves hole quality. Using a tool made from VHM ensures high rigidity and resistance to chipping, which is especially important when producing repeatable pilot holes on CNC machines and drilling centres. The result is reduced scrap rates and fewer re‑set operations, improving throughput without compromising accuracy.

Coating and geometry that sustain cutting speed

A TiAlN coating increases thermal resistance and maintains hardness at elevated temperatures, permitting more aggressive cycle parameters where appropriate. The 142° point angle offers a broader contact area for dependable centring and is ideal for preparing thread starts; this geometry reduces walking and provides a clean chamfer in the same pass, eliminating a separate operation and saving machining time.

Machine compatibility and secure clamping

Equipped with a cylindrical shank manufactured to DIN 6535‑HB and h6 tolerance, the tool guarantees precise mounting in standard collets and holders used on NC equipment. The shank and overall dimensions (total length 70 mm, flute length 24 mm, diameter 10 mm) enable stable overhang management and predictable tool behaviour. The tool is right‑hand cutting and supports a recommended feed in steel up to 800 N of 0.11 mm/rev, offering a clear baseline for process planning.

Broad material suitability for workshop flexibility

The geometry and material combination make this centre drill particularly appropriate for high‑strength steels, steel castings, grey cast iron, stainless steels and non‑ferrous metals, allowing a single tool to cover a wide range of applications. For production environments aiming to standardise tooling, this reduces tool inventory while maintaining the ability to produce precise centres and chamfers reliably on both one‑off and batch work.

FAQ

Which materials can be machined with this NC centre drill?

The TECWERK NC centre drill D10 mm (SKU 2000865842NW) is suitable for high‑strength steels, steel castings, grey cast iron, stainless steels and non‑ferrous metals, offering versatile use across workshop applications.

Can the tool centre and chamfer thread holes in one operation?

Yes, the tool’s geometry and 142° point angle are designed to centre and chamfer thread holes in a single pass, reducing cycle time and eliminating a separate chamfering step.

What shank standard and tolerance does the tool use?

The tool features a cylindrical shank to DIN 6535‑HB with h6 tolerance, ensuring secure and concentric clamping in standard holders and collets on NC machines.

Is the TiAlN coating suitable for high‑temperature cuts?

The TiAlN coating provides enhanced thermal resistance and wear protection, making the drill well suited to demanding operations where increased surface temperatures occur.
