Tip: quick and dirty Step drilling

hydroguy2 · #1 02-12-2010, 06:41 PM

When using a step drill to upsize a bunch of holes, I like to use a Black Sharpie marker to darken the next step up. This allows me you "see" the size I want while the drill is spinning. Run it up to the black and move to the next hole. No wondering, did I go to far? or do I drill one more step?

Just make sure you mark the correct step.

Cool, I like to put the sharpie mark on the final size. Nice tip.

Good tip! I have been wraping electrical tape around mine as a marker. This will be a lot easier.

I do the same sort of thing myself and I can also attest that it does indeed work quite well.

Better yet, get an assortment of colored Sharpie pens and color each step a different color. When you get ready to drill, just remember what color you need to stop on.
