    I'm attempting to install some sliders on my double cab. They are "bolt on" which means, after you drill forty 1/2" holes, you bolt them on. And that's my issue....drilling out those holes.

    I've tried two different kinds of drill bits intended for "hard steel" and my progress is painfully slow even when oiling the bits as I go. I'm pretty sure my drill will be at the end of its life after this (if it even makes it). It's so slow I'm having to cool off my drill with compressed air after a while before I can continue.

    Is there a secret to this?

    I would return them and buy SOS Bolt on sliders. They just bolt on.

    Sharp drill bits, Vermont American makes great ones...If you have a compressor that can support it, pick up an air drill (self cooling).
    Plus, you will get more RPMs out of it.

    Drill a smaller hole to start with and work your way bigger.

    Also if you are actually using "oil", as in 3-in-1, motor or some other lubricating oil, then STOP--you are using the wrong stuff. Get some cutting fluid--Tapmatic #1 Gold is my favourite...

    Thanks for the advice but I'm not willing to explore that option.
    Is faster RPM better? Is more pressure better or worse?I've been using the DeWalt bits that state they are for heavy steel. Brand new bits.
    I was trying to go from 1/4" to 1/2" but I think that was a bit too big of a jump. Using about 3 other sizes in between now and that's seem to made the most difference.
    I was using some old diff oil in the garage actually. What's different about cutting fluid?

    X2 - start with smaller pilot hole, then I would use a decent "step bit" - they cut really well! Even the step bits at Harbor Freight have served me very well...

    1/4 to a half is a hell of a jump. Your never gonna cut that. Get out a good complete set of Irwin bits and work your way from smallest to biggest and go to town.

    Are you seriously drilling 40 holes in your frame? I would weld them on before drilling so many holes in my frame. Good luck.

    This, but I'm biased. There are other brands that bolt straight on as well. I'm not sure what brand you bought but I hope they're worth it.
    @ItalynStylion
    Slow speed with pressure. I just drilled 1/2" holes for my t-case skid plate. Put my Craftsman c2 19.2v drill on my floor jack and lightly applied pressure. Went through like pretty easy, used a few shots of wd-40. Drill bit was a standard gold colored one bought a few years ago from sears.

    How many Holes do you need to drill??

    A little planning would have been a big Help

    Since I did Quite a lot of frame Stretching A mag drill was not a luxury 1/2" annular cutter would go through that like butter

    I use it quite often repairing Tacoma frames I just clamp a 1/2" plate to the frame

    The slower you can let your bit turn, the better. It will actually cut through the steel faster. Step bits are nice to use for this as well. Use lots of oil as it lubes and cools. Clean away the metal shavings as they can dull your bit.

    Do they use any existing holes? I put 3 bolts in my sliders then had a welder finish it off. Cost me 60 bucks. Save a little cause they were already mounted. I think drilling holes in the frame is too much work and not as good as welded.

    How many attachment points x 3 holes = ??
    15 minutes weld time. Done, never worry about.
    Don't drill 36 to 40 holes in your $36000.00 dollar truck.

    Cutting oil like Tap Magic. Drill slow and constant pressure. Drill all holes with 1/8" or 3/16" bit and work your way up from there. Step up 1/16" or 1/8" each time. Constant cutting oil, keep the drill bit cool.

    Or, buy ours and never drill a hole.

    This has been my experience thus far too.
    No existing holes sadly. Really annoying.
    4 attachment points, 3 holes each, 2 sliders.....24 holes. Don't know what the fuck I was smoking before. Probably my drill bit lol.
