NC pilot drill D20 mm — Solid carbide, TiAlN, 90° (TECWERK)

The NC pilot drill D20 mm by TECWERK is designed for positions-accurate, rapid pilot drilling on NC machines and drilling centres, combining a short cutting length with a DIN 6535-HA cylindrical shank for secure machine holding

• Solid carbide with TiAlN coating
• 90° point for precise centring
• Cylindrical shank to DIN 6535-HA
• Suited for high-strength steels and stainless

Faster, more precise pilot drilling for CNC production

The tool delivers a clear production advantage by combining a 90° centre point with a compact cutting length, enabling precise centring and simultaneous chamfering of threaded holes in a single pass. Designed for NC machines and drilling centres, this pilot drill reduces setup time and eliminates a follow-up operation, improving cycle times. The right-hand cutting geometry and the nominal 20 mm diameter maintain process stability when used at the recommended feed settings, helping to avoid drift and misalignment during automated runs.

Durable edge and thermal resistance for sustained throughput

Constructed from solid carbide and finished with a TiAlN coating, the tool resists abrasive wear and withstands elevated cutting temperatures that occur during interrupted or high‑load drilling. The combination of carbide substrate and aluminium‑titanium‑nitride surface treatment extends tool life and preserves the cutting geometry under demanding conditions. This results in fewer tool changes and less unplanned downtime, which increases overall equipment effectiveness in production environments that frequently machine high‑strength alloys.

Machine compatibility and repeatable clamping accuracy

The cylindrical shank conforms to DIN 6535‑HA and the shaft tolerance is h6, ensuring repeatable clamping in standard tool holders and spindles. This mechanical compatibility supports consistent concentricity and run‑out control, which are essential for accurate pilot holes and subsequent thread forming. The tool is especially effective for high‑strength steels, steel castings, grey cast iron, stainless steels and non‑ferrous metals, allowing a single tool to cover a broad material mix in small to medium batch production.

Practical operating parameters and inspection guidance

With an overall length of 100 mm and a spiral length of 35 mm, the design balances rigidity and chip evacuation for controlled cutting. The specified feed recommendation in steel under a cutting force of up to 800 N is 0.16 mm/rev, providing a baseline for process planning; adjustments should be made according to material grade and machine rigidity. The h6 diameter tolerance supports precision positioning for serial operations, while the right‑hand cutting direction matches standard spindle configurations on modern NC equipment.
