TECWERK NC Spot Drill D.8 mm, HSS‑Co, 120°

The TECWERK NC Spot Drill D.8 mm HSS‑Co 120° is a right‑hand cutting spot drill with a cylindrical shank to DIN 1835‑A, designed for precise positioning and rapid spotting on NC machines and drilling centres.

• HSS‑Co construction for higher wear resistance
• 120° tip for accurate centring
• Cylindrical shank to DIN 1835‑A
• Right‑hand cutting for NC positioning

Precise centring and chamfering in a single operation

The combination of a 120° tip and cobalt‑enriched high‑speed steel (HSS‑Co) enables consistent centring with minimal walking and a clean chamfer at the hole entrance. This reduces the need for secondary operations: the tool both locates the bore and deburrs the edge, saving cycle time on production runs. The geometry is optimised to produce tight concentricity so that subsequent drilling or tapping begins from an accurately positioned start, improving hole quality and lowering scrap rates.

Engineered for consistent NC performance and predictable feeds

A cylindrical shank to DIN 1835‑A ensures secure clamping and repeatable concentricity in toolholders and collets on NC machines and drilling centres. The right‑hand cutting design supports reliable chip formation during the initial spot; the tool is specified for a recommended feed in steel up to 800 N of 0.07 mm/rev, offering a balance between stability and productivity. For customers unfamiliar with the notation: 0.07 mm/rev means the tool advances 0.07 millimetres per spindle revolution, a common way to describe feed for rotational cutting tools.

Simple integration into workshop workflows and long‑term value

Durable HSS‑Co composition and standardised shank form make the tool straightforward to fit into existing tooling arrays and replacement cycles. The dual function — centring plus chamfering — shortens setup and reduces tool changes per part, contributing to lower overall machining costs and higher throughput. Combined with Metav’s distribution and quality filtering from Emmerich, the tool offers dependable supply and traceable quality, an advantage for maintenance planners and production managers seeking consistent results.

FAQ

What materials is this spot drill suitable for?
The TECWERK NC Spot Drill D.8 mm HSS‑Co is supplied in cobalt‑enriched high‑speed steel, suitable for standard steel machining tasks and designed for robust performance during centring and initial spot drilling.

Can this tool be used in standard collets and holders?
Yes, the cylindrical shank to DIN 1835‑A allows secure clamping in conventional collets and holders used on NC machines and drilling centres, ensuring repeatable runout and concentricity.

What does the feed specification 0.07 mm/rev mean in practice?
A feed of 0.07 mm/rev indicates the axial advance per spindle revolution; for the TECWERK spotting drill this feed in steel up to 800 N balances cutting stability and productivity for initial spotting operations.

Does the tool perform chamfering as well as centring?
Yes, the geometry is designed to combine centring and chamfering of thread holes in one pass, reducing the need for separate deburring operations and saving cycle time.

How does the 120° tip affect hole quality?
The 120° tip reduces walking on the workpiece and produces a well‑defined centre that guides subsequent drilling, improving hole alignment and reducing scrap.
