Product catalog summary
Overview: This document provides technical specifications and guidelines for the Carbide 3 Flutes Dube H Drill, designed for hardened and heat-treated steels. It includes detailed measurements, order numbers, and cutting conditions for various materials and hardness levels.
Specifications:
  • Drill Design: Carbide drill with 3 flutes, suitable for hardened steels (HRc52~65) and heat-treated steels.
  • Coating: HR coating for enhanced heat and wear resistance, extending tool life.
  • Point Design: Features point thinning to minimize chipping, with 90 and 140-degree point angles for optimal performance.
  • Flute Design: Designed for efficient chip evacuation and drill rigidity, ensuring stable drilling.
Dimensions: The document lists various drill sizes with specific diameters, flute lengths, overall lengths, and shank diameters, each associated with a unique order number.
Cutting Conditions:
  • Material Hardness: Guidelines provided for materials ranging from mild steels to hardened steels, with specific RPM and feed rates for different diameters.
  • Clamping: Emphasizes the importance of stable clamping to maintain tool durability.
  • Chip Evacuation: Recommends using cutting oil or soluble cutting fluid for smooth chip evacuation.
  • Adjustments: Advises adjusting spindle speed and feed rate if conditions exceed machine capabilities or if chattering occurs.
Recommendations:
  • Use the provided cutting conditions as reference points, adjusting based on actual machining requirements and equipment.
  • For drilling depths exceeding 5 times the diameter, adjust the peck feed rate accordingly.
