Faithfull FAISD630 HSS Cone Step Drills 6-30mm

This step drill bit is designed for drilling holes of varying sizes in materials up to 4 mm thick without changing bits. It features a size range from 6 to 30 mm with 2 mm increments, allowing precise, incremental drilling for tasks requiring multiple hole sizes. The bit is made from High-Speed Steel (HSS) and has a shank diameter of 10 mm, compatible with standard drill chucks and suitable for use with various power drills and drill presses. Its design enables parallel holes within a specific size range as you drill, and its 4 mm step depth supports controlled material removal. The tool is intended for metal drilling, with guidance to mark, secure, and start at low speed, progressively increasing as needed, and to use cutting fluid if necessary to extend tool life and improve cut quality.
