3mm NC Spot Drill HSS-Co 90° With Cylindrical Shank DIN 1835-A, Right-Hand Cutting - TECWERK

Take advantage of precise centre and chamfering in a single pass with the combination of HSS‑Co construction, a 3 mm diameter and a 90° point angle for fast, position‑accurate spot drilling on NC machines; order the TECWERK tool directly via Metav Werkzeuge or consult the Metav team for specification support.

TECWERK NC spot drill, 3 mm, HSS‑Co, 90°

The NC spot drill 3 mm HSS‑Co 90° is a precision centre and chamfering tool designed for rapid, position‑accurate use on NC machines and boring mills.

• Cobalt HSS construction for tool life
• Cylindrical shank to DIN 1835‑A
• Position‑accurate spot drilling on NC machines
• Centres and chamfers tapped holes in one operation

Faster set‑up and reliable positioning for serial work

The solid HSS‑Co body and the cylindrical shank to DIN 1835‑A ensure repeatable clamping and minimal run‑out, which translates into fewer set‑ups and consistent hole quality. For production environments where every second counts, the combination of a 90° point geometry and a 3 mm pilot diameter reduces wandering on start‑up and secures exact positioning on the first cut. This results in shorter cycle times on milling centres and drilling units while maintaining the required accuracy for downstream tapping operations.

One‑pass centring and chamfering to save process steps

Designed for simultaneous centring and chamfering of tapped holes, the tool removes the need for separate pilot and countersink operations. The integrated geometry offers a clean chamfer suitable for thread starts, reducing rework and improving thread engagement. Where previously two tools or steps were needed, the single‑pass approach delivers clear productivity benefits and a measurable reduction in handling time on the shop floor.

Robust cutting performance with defined feed data

Rated for operations with a feed of 0.03 mm/rev in steels up to 800 N, the drill provides a defined cutting window for controlled material removal. The right‑hand cutting geometry and heat‑resistant cobalt alloy permit reliable performance under typical NC feeds and speeds, while the precise specification simplifies process documentation and repeatability across batches. For technicians less familiar with cutting data, the stated feed figure offers a straightforward starting point for trial cuts.

Compatibility, clamping and machine use explained

The shank conforms to DIN 1835‑A, making the tool compatible with standard cylindrical holders and chucking systems commonly found on NC drilling machines and boring mills. Its construction suits use as a pilot or spot drill in mixed production environments where changeovers occur frequently. The geometry and material selection focus on longevity and consistent hole quality rather than decorative finish, making the tool a pragmatic choice for engineering workshops and production lines.
