Product Overview: HSS Heavy-Duty Short Flute Drill 3D – UDL Series
【Product Features & Why We Recommend It】
- French Brand Professional Quality: Originating from a professional French cutting tool brand with rigorous quality control — recommended for users seeking reliable general-purpose drilling performance with a practical balance of quality and cost efficiency.
- Heavy-Duty Short Flute Rigidity Design: The short flute design minimizes tool overhang, providing higher cutting edge rigidity and vibration resistance compared to standard length drills — recommended for general-purpose drilling applications with moderate demands on hole position accuracy and drilling stability.
- 4–7D Depth-to-Diameter Ratio Wide Coverage: Depth-to-diameter ratio spanning 4–7D — recommended for flexible selection based on workpiece thickness and drilling depth, suitable for general drilling needs from thin plates to moderate depth applications.
- 127 Specification Ultra-Wide Coverage: Available in diameter 1–16mm, flute length 6–58mm, and overall length 26–115mm across 127 specifications — recommended as the general-purpose stock drill for factories and machining centers, covering the vast majority of drilling size requirements within a single series.
- Economic Practical First Choice: HSS material combined with French brand quality achieves a favorable balance between cost and performance — recommended as the economical and practical first choice for high-volume consumable drilling operations.
【Machining Applications & Uses】
- Primary Use: General-purpose drilling, through-hole machining, and pre-drilling operations.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC30, delivering stable general-purpose drilling cutting performance.
- M-Class (Stainless Steel): SUS304, SUS316, and other high-toughness stainless steel — use of appropriate cutting fluid and reduced spindle speed is recommended to suppress work hardening and maintain drilling stability.
- N-Class (Non-Ferrous Metals): Aluminum alloys, pure copper, brass, and other non-ferrous metals — the short flute high-rigidity design combined with appropriate cutting fluid ensures smooth chip evacuation and prevents built-up edge formation.
