Drilling range 1/4 to 1 inch
The Evolution Power Tools SD-10 is a straight-flute step drill that produces holes from 1/4 inch up to 1 inch in a single bit. It is designed for electricians, metalworkers and maintenance technicians who need to enlarge existing holes or create multiple diameters without changing tools. The bit is sold new and ships directly from the manufacturer.
Suited for thin sheet metal and plastic
This step drill works best in thin sheet metal, conduit and plastic where a straight flute gives a clean, round hole. Builders who need to drill thick plate, hardened steel or deep holes beyond the 1-inch maximum should look at dedicated twist drills or hole saws instead. The tool carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.
Maximum hole diameter 1 inch
The largest step on the bit measures 1 inch, so any project that requires a hole larger than that cannot be completed with this drill. Buyers who need diameters above 1 inch must select a different step drill or a hole-saw set. The straight-flute design and 1/4-inch starting size are the other fixed parameters that determine fit for the job.

Questions about this item
What size range does the 1/4 to 1" straight-flute step drill cover?
The Evolution SD-10 steps from 1/4 inch up to 1 inch in a single bit, letting you drill multiple diameters without changing tools.
What shank type fits the SD-10 into a drill chuck?
The step drill uses a standard straight shank that locks into any 3-jaw chuck, so no special adapter is required.
How do you avoid snapping the tip when starting a hole?
Apply light pressure, keep the bit perpendicular, and let the straight flutes cut gradually — forcing the first step is the most common mistake.
