DH Series Drills

Product catalog summary
Tool Design
The Sutton DH drill series features a parabolic flute style, allowing for a larger core diameter and more flute space compared to standard designs. This results in heavier feed and less pecking. The 40° helix angle with rake correction provides a strong cutting edge and excellent chip evacuation across various materials. The U-point geometry ensures a constant rake angle along the cutting edge, promoting controlled chip breakage and centering.
Material
DH drills are made from a cobalt grade of high-speed steel, offering excellent cutting properties, high red hardness, and good toughness, suitable for materials with hardness up to 1200 N/mm².
Coating
The drills are coated with TiAlN (Futura Nano), which is ideal for applications with high thermal loads due to its nano-layered structure that balances hardness and internal stress.
Features
  • 130º profile web thinned U-point geometry for high strength
  • Fast 40º helix
  • Parabolic flute design for optimal chip transportation
  • Cobalt grade high-speed steel (HSS Co)
  • TiAlN coating for longer tool life
Benefits
  • Controlled centering and chip breakage
  • Increased stability
  • Fast chip evacuation
  • Less pecking required
  • Improved heat dissipation
Performance Comparison
A study comparing the DH series with conventional drills showed that the DH series has a longer tool life at higher cutting speeds. The data indicates superior performance in terms of the number of holes drilled at various cutting speeds.
Applications
The DH series is optimized for high-quality drilling from 3 to 12 times the diameter in depth, suitable for small to medium batch sizes and tough materials.
Overview: The document is a technical catalogue detailing various types of high-performance drills, their specifications, and applications. It includes information on different drill series, materials, surface finishes, and geometries.
Specifications: The drills are categorized by series such as Jobber, Long Series, and Extra Long. Each series has specific catalogue codes (e.g., D158, D163, D170) and discount groups. The materials used include High-Speed Steel (HSS) and HSS Co, with surface finishes like Bright (Brt) and Titanium Aluminum Nitride (TiAlN). The drills are designed for materials with strengths up to 1200N/mm².
Design Features: The drills feature a parabolic flute design for optimal chip transportation and a point geometry that ensures high strength. The point type is typically 130º, and the shank tolerance is h9. The TiAlN coating is noted for extending tool life.
Applications: The drills are suitable for a wide range of materials, including various steels, cast irons, and non-ferrous metals. The document provides an application guide with recommended speeds and feeds for different materials and conditions.
Size and Dimensions: The document lists drills by size, with dimensions provided for diameter (d1), overall length (l1), and flute length (l2). Sizes range from small diameters (e.g., 1.0 mm) to larger ones (e.g., 16.0 mm).
Additional Notes: The document includes notes on drilling techniques, such as the need for step feeding or pecking for depths greater than three times the diameter. It also provides formulas for calculating revolutions per minute (n), cutting speed (vc), and feed rate (vf).
