Product Overview: HSS Noss Drill – NOSS Series
【Product Features & Why We Recommend It】
- Taiwan Brand Professional Manufacturing: Originating from a professional Taiwanese cutting tool brand with strict quality control — recommended for users with standard demands on large-diameter precision drilling stability and tool consistency.
- Noss Drill Dedicated Design: Features a Noss drill dedicated geometry — recommended for precision drilling applications with higher hole diameter accuracy requirements, providing superior hole wall surface quality and dimensional accuracy compared to standard twist drills, particularly suited for precision machining of large-diameter holes.
- Large-Diameter Dedicated Specification Coverage: Available in the large-diameter range of 13–35mm — recommended for large-diameter precision drilling applications where standard twist drills cannot achieve the required accuracy, effectively bridging the limitation of small and medium diameter drill applicability.
- Weldon Shank Stable Clamping: Features a Weldon shank design providing superior clamping stability compared to standard straight shanks — recommended for large-diameter precision machining applications with strict requirements on hole diameter accuracy and drilling concentricity.
- 45 Specification Flexible Selection: Available in diameter 13–35mm, flute length 80mm, and overall length 137mm across 45 specifications — recommended for flexible selection based on workpiece hole diameter, covering all types of large-diameter precision hole machining needs.
【Machining Applications & Uses】
- Primary Use: Large-diameter precision hole drilling, high-accuracy through-hole and blind hole machining, and large-diameter precision forming of non-ferrous metal components.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC30, where the Noss geometry design delivers stable large-diameter precision drilling performance.
- N-Class (Non-Ferrous Metals): Aluminum alloys, pure copper, brass, and other non-ferrous metals — the Noss large-diameter design combined with appropriate cutting fluid ensures smooth chip evacuation and prevents built-up edge formation, maintaining excellent hole wall quality.
