Solid Carbide Gun drill
A solid carbide gun drill is a type of precision machine tool that is used for drilling. It is manufactured from a solid carbide piece and features a high feed rate. It is available in different sizes, from 0.9mm to 12mm. It is suitable for drilling small holes with very precise requirements in geometrical and dimensional accuracy.
These gun drills are useful in many industries, including automotive fuel systems, medical instruments, and the glass industry. The tubular construction of a solid carbide gun drill allows for increased penetration rates, while the non-braze joint at the tip of the gun drills increases their tool life. Unlike conventional gun drills, however, these tools require specific operating parameters.
The primary disadvantages of solid carbide gun drill tools are their relatively high initial cost and limited length. Brazed gun drills, on the other hand, have a carbide tip brazed onto a machined steel shank, allowing for virtually any length. Brazed gun drill tools offer the benefits of low initial cost and short lead time, but are not as rigid as solid carbide tools. In addition, the accuracy potential of these gun drills is lower when using smaller sizes. However, they offer a higher capacity of use, including their indexability for use on machining centers.
Another major advantage of a solid carbide gun drill is its ability to machine deep holes with excellent finishes. They are useful for a variety of applications and are available in various carbide grades and coatings. Their coatings and surface finishes help maximize tool life and chip evacuation. They are also ideal for drilling holes ranging from 0.5mm to 50 mm in diameter.
