Prethread drilling is a complex operation across a wide range of applications. enables endusers to perform prethread holes reliably and economically for Unified thread form tap drill size holes (3/8 to 7/8, UNC & UNF) and ISO M standard tap drill size holes (M8 to M24). The line s versatility now eliminates the need for step drills, reducing excess inventory and downtime. Already known for outstanding performance in the industry, this additional drill/ chamfer capability within the product line makes it the ideal solution meeting the machining market s growing demand for simplified, costeffective solutions.
