Product description
- Set of step drills HSS 3 pieces D. 4-12 / 4-20 / 6-30 MM
With the 3-piece Hikoki 780114 hss step drill set, you can drill and deburr sheet materials cleanly in a single operation without constantly swapping bits. This set covers hole diameters from 4 mm up to 30 mm with versatile ranges of 4-12 mm, 4-20 mm, and 6-30 mm. Crafted from durable hss high-speed steel, the drills maintain their sharp cutting edges under heat for extended wear resistance. The stepped geometry prevents thin sheets from snagging or distorting, delivering smooth, burr-free, and perfectly round holes without pre-drilling. Ideal for installing cable glands, metal fabrication, and hvac work.
