Product Specifications:
This 2‑flute solid carbide twist drill is engineered for high‑performance drilling in steel, stainless, and cast iron. The 140° point angle provides a stronger cutting edge than standard 118°, reducing chipping and extending tool life in harder materials. The AlTiN coating (bronze) offers excellent heat resistance (up to 1100°C) and low friction, while the internal coolant holes deliver high‑pressure fluid directly to the cutting zone – critical for deep holes and high‑speed operations.
The 12mm diameter drill features a 60mm flute length (5×D) and 132mm overall length, with a maximum recommended depth of 4.5×D (54mm). The 2‑flute design provides large chip flutes for efficient evacuation, especially important when drilling tough alloys. Recommended cutting parameters: 80‑120 m/min cutting speed, 0.18‑0.30 mm/rev feed. Always use through‑coolant (≥ 40 bar) for optimal chip removal and tool life.
Applications include automotive powertrain components, injection mold cooling channels, heavy equipment parts, and stainless steel flanges. For depths beyond 5×D, consider our specialized deep‑hole drills. Custom coatings (TiAlN, DLC) and shank configurations are available for OEM orders. Upgrade your drilling process with this high‑performance carbide internal‑coolant drill – designed for production environments where consistency and tool life matter most.
