What this step drill does
The Evolution Power Tools SD-6 is a straight-flute step drill that cuts holes from 3/16 inch up to 1/2 inch in a single pass. It is aimed at technicians and DIY users who need to enlarge pilot holes quickly in thin metal, plastic or wood without changing bits.
Capacity and where it stops
The tool covers a range of intermediate diameters between the smallest and largest steps, giving enough headroom for common conduit, fastener and wiring holes. Once the 1/2 inch step is reached the drill cannot go larger, so any project needing bigger diameters will require a different bit.
Build and daily use
The straight-flute design helps the bit self-start and reduces walking on flat surfaces, while the stepped profile lets you deburr each hole as you go. California Proposition 65 notices indicate the product contains chemicals known to the state to cause cancer and birth defects or other reproductive harm, so appropriate protective equipment and ventilation are advisable during prolonged use.

Questions about this item
Will the 3/16 to 1/2 inch range cover the pilot holes I already drill in sheet metal?
Yes, the step drill spans 3/16 inch through 1/2 inch in one bit, so it replaces several individual twist drills you may keep for thinner gauge work.
How can I confirm the straight flute cuts cleanly after I mount it in my drill press?
Run the bit at low speed with cutting fluid; a smooth, round hole without burrs or chatter marks shows the flute geometry is performing as designed.
Does the package include cutting fluid or a storage case, or must I buy those separately?
The box contains only the SD-6 step drill; cutting fluid and a protective case are not included and must be purchased separately.
