Customer Questions & Answers

  • Question: What is the main application of the Sandvik Coromant CoroDrill Delta-C R840 drill bit?

    Answer: The Sandvik Coromant CoroDrill Delta-C R840 is primarily designed for precision drilling in a variety of materials, including steel and other metals. Its 140-degree point ensures precise entry and reduces the risk of damage to work surfaces. This drill bit excels in applications requiring high productivity and strength, making it ideal for manufacturing environments and high-volume production where efficiency is crucial.
  • Question: What are the benefits of using a carbide drill bit like the CoroDrill Delta-C R840?

    Answer: Carbide drill bits, such as the CoroDrill Delta-C R840, offer exceptional hardness and wear resistance compared to traditional steel bits. This durability results in a longer tool life and improved accuracy, reducing the frequency of replacements. Additionally, the multilayer finish on this drill bit minimizes friction and heat generation, making it a suitable choice for high-speed applications where consistent performance is essential.
  • Question: How does the round shank design benefit the user?

    Answer: The round shank design of the CoroDrill Delta-C R840 allows for easy compatibility with a variety of drill chucks and holders. This versatility makes it a convenient option for users who may need to switch between different machines quickly. Furthermore, the secure grip provided by the round shank reduces slippage during operation, contributing to enhanced precision and overall drilling effectiveness.
  • Question: What cutting depth can the Sandvik Coromant CoroDrill Delta-C R840 achieve?

    Answer: The CoroDrill Delta-C R840 features a cutting diameter of 4.5mm and a cutting length of 24mm, allowing for effective drilling in materials up to that depth. This specification makes it suitable for various applications, including precision holes in thin materials and reaming operations where depth control is critical. Users in industries such as automotive and aerospace benefit from this drill bit's ability to create deep, consistent holes.
  • Question: Is the CoroDrill Delta-C R840 suitable for high-speed cutting?

    Answer: Yes, the CoroDrill Delta-C R840 is specifically designed for high-speed cutting applications. The carbide material and advanced multilayer coating help manage heat build-up and maintain cutting efficiency at elevated speeds. This feature is particularly advantageous in production environments where time efficiency is critical, allowing operators to achieve faster cycle times without compromising on quality.
  • Question: Can the CoroDrill Delta-C R840 be used for drilling in soft materials?

    Answer: While the CoroDrill Delta-C R840 is optimized for harder materials like steel, it can also be used effectively on softer materials such as aluminum and plastics. Its robust design ensures clean, accurate holes even in these softer substrates. This versatility makes it an excellent choice for workshops that deal with various materials, as it can effectively adapt to different drilling requirements.
  • Question: What makes the 140-degree point of the CoroDrill Delta-C R840 unique?

    Answer: The 140-degree point of the CoroDrill Delta-C R840 is designed to enhance penetration and reduce the chipping risk at the tip during the drilling process. This specific angle enables smoother entry into materials, minimizing deformation or burr formation. Users often find that this design improves drilling speed and accuracy in jobs requiring tight tolerances, making it ideal for precision engineering tasks.
  • Question: What should I consider when selecting a drill bit size?

    Answer: When selecting a drill bit size such as the 4.5mm offered by the CoroDrill Delta-C R840, consider the diameter of the hole needed, the material type, and the application requirements. A bit too large can weaken the material, while one too small may not achieve the desired outcome. Carefully assessing these factors ensures the chosen drill bit meets operational needs, whether in mechanical assembly or manufacturing processes.
