RUKO TOOLS Step Drill Bit: 7/8" to 1-1/8", TiN-Coated HSS, 3-Flats Shank

A RUKO TOOLS step drill bit is used for drilling clean, burr-free holes in thin materials like sheet metal, plastic, and wood. The 7/8" to 1-1/8" range allows multiple hole sizes with one bit, ideal for electrical panels, HVAC ductwork, and automotive repairs.

The RUKO TOOLS 101709T step drill bit has a size range of 7/8" to 1-1/8", is made of TiN-coated high-speed steel (HSS), and features a 3-flats shank for secure chuck grip. It is not impact rated, so use only in standard drill chucks.
