12mm NC Spot Drill HSS-Co 120° Right-Hand Cylindrical Shank, h8 Tolerance - TECWERK

With a 12 mm diameter, HSS‑Co construction and a 120° centring tip, this NC centre drill combines precise positioning with chamfering in a single pass to reduce cycle times and increase process reliability. Its DIN 1835‑A cylindrical shank and h8 tolerance ensure secure clamping and repeatable concentricity; order directly via Metav Werkzeuge or consult the team for application guidance.

NC centre drill D12 mm – HSS‑Co, 120° tip (TECWERK)

The NC centre drill D12 mm is engineered for precise spot drilling and simultaneous chamfering on NC machines and drilling centres, delivering fast and accurate preparation of tapped holes in one operation

• Cobalt HSS for high wear resistance
• DIN 1835‑A cylindrical shank
• 120° tip for accurate centring
• Feed 0.1 mm/rev in steel up to 800 N

Reduce cycle time with precise centring and chamfering

This centre drill is optimised for fast, position‑accurate starts on CNC machines and drilling centres. The combination of a 120° tip and a 12 mm diameter provides stable entry and reliable centring before subsequent drilling or tapping. Using the specified 0.1 mm/rev feed in steel up to 800 N yields consistent chip formation and reduces the risk of run‑out, which in turn shortens setup and processing time. The result is measurable throughput improvement without compromising hole quality.

Durable material and shank standard for repeatable results

Manufactured from HSS‑Co, the tool offers increased red‑hardness and wear resistance compared with standard high‑speed steel, helping to maintain edge geometry across long production runs. The DIN 1835‑A cylindrical shank permits secure clamping in standard tool holders, while a tolerance h8 on the cutting diameter supports consistent concentricity in serial production. These characteristics combine to lower reject rates and extend the interval between tool checks.

Easier integration into existing NC workflows

With a 30 mm flute length and an overall length of 102 mm, the drill is designed for straightforward handling and tool‑changer compatibility. The right‑hand cutting geometry supports conventional machining directions and predictable chip evacuation, making the tool suitable for automated sequences that require centring and chamfering in a single step. This integration reduces the number of tool changes and simplifies process planning for tapping preparations.
