3mm Solid Carbide NC Spot Drill 90° Right-Hand Cylindrical Shank h6, DIN 6535-HA - TECWERK

High-precision centring with a solid carbide construction and a 90° point angle provides fast, repeatable hole starts while the cylindrical shank to DIN 6535-HA ensures secure clamping and repeatability on automated equipment; order directly via Metav Werkzeuge or ask our consultants for application support.

TECWERK NC spot drill Ø3 mm, solid carbide, 90°

TECWERK NC spot drill Ø3 mm, solid carbide is a purpose-built pilot and chamfering tool for position-accurate starts on NC machines and drilling centres.

• Solid carbide for high stiffness
• 90° point for precise centring
• Cylindrical shank to DIN 6535-HA
• Suitable for tough steels and castings

Accurate starts and consistent results for series production

The TECWERK NC spot drill Ø3 mm combines a compact geometry with a 90° point angle, delivering precise centring for subsequent drilling or tapping operations. The solid carbide construction resists deflection and wear, which translates into reduced scrap rates and fewer reworks on repeated cycles. Designed for use on automated centres and NC machines, the tool supports rapid, repeatable starts that help maintain cycle-time targets without sacrificing positional accuracy.

One‑pass centring and chamfering for mixed materials

With its short flute and robust tip, the tool enables centring and chamfering of threaded holes in a single operation, cutting handling time. The geometry is particularly suited to a range of workpiece materials, including high‑strength steels, stainless steel, grey cast iron and non‑ferrous metals, delivering clean starts even in demanding applications. For steels under cutting resistance up to 800 N, the recommended feed is 0.05 mm/rev, which balances tool life and surface condition while keeping process stability.

Shank, tolerance and machine compatibility for reliable clamping

The cylindrical shank conforms to DIN 6535‑HA, simplifying toolholder selection and changeover. Diameter tolerance h6 assures repeatable concentricity in collets and chucks, while the right‑hand cutting direction matches standard spindle rotations on most machining centres. These mechanical features reduce setup time, improve runout performance and preserve hole quality across batches, making the tool a practical choice for production and workshop environments where accuracy and throughput matter.
