Product catalog summary
Overview: The document provides detailed specifications and features of Dapra's modular extensions, which are designed for use with various modular heads, including those from competitors. These extensions are suitable for end mill holders, milling chucks, and heat-shrink holders.
Specifications:
  • Universal compatibility with screw-on modular heads.
  • Cylindrical inch shanks adaptable for different holders.
  • Available in three sizes for modular head sizes from 3/4” to 1-1/2”.
  • Carbide core for enhanced vibration dampening, reduced deflection, and improved rigidity.
  • Optional add-on extensions for an additional 2” reach.
  • Thru-coolant feature for air or coolant delivery at the cutting edge.
Product Variants:
  • Carbide Core Modular Extensions: Ideal for standard inch end mill holders, offering optimum rigidity and no braze joints. Available in various sizes with specific shank diameters and effective lengths.
  • Solid Carbide Modular Extensions: Made of high-density tungsten for extra resistance to vibration and deflection. These extensions can be cut in half for use with two different modular heads.
  • Heavy-Metal Modular Extensions: Designed for maximum rigidity and equipped with thru-coolant features. Available in metric shank diameters for clearance with inch size modular heads.
Key Features:
  • Enhanced vibration dampening and rigidity due to carbide core.
  • Thru-coolant capability for efficient cooling and air delivery.
  • Modular design allows for flexibility and compatibility with various heads and holders.
Applications: These modular extensions are suitable for use in high-performance milling operations where precision and rigidity are critical. They are particularly beneficial in reducing deflection and chatter during machining processes.
