Tungaloy Corporation announced the expansion of its DeepTriDrill series, now available in a minimum diameter of ø8 mm—the smallest in the industry. This expansion includes 16 drill body variants, two insert options, two guide pads, and an adjustable shim set, providing enhanced flexibility for deep hole drilling in mold and automotive manufacturing.
Challenges and Trends
In the mold and automotive industries, deep hole machining is indispensable. Specifically, high-precision and efficient machining is required for cooling holes in molds and deep holes in shafts. However, conventional brazed gun drills require regrinding, making tool management cumbersome and hindering productivity improvement. Additionally, their low machining efficiency often creates bottlenecks in production lines. Given these challenges, there is a growing demand for tools that offer high efficiency and easy management.
Product Overview
DeepTriDrill is a high-performance deep hole drilling tool offered by Tungaloy. Its indexable design allows for easy tool management while ensuring stable and highly efficient machining. With a wide lineup that includes small-diameter options, it can accommodate various deep hole drilling applications. Utilizing BTA tool technology, DeepTriDrill delivers excellent roundness, straightness, and surface finish. Compared to conventional brazed gun drills, it achieves twice the machining efficiency.
