Don't buy cheap drill bits

[Hunter]

So while I was replacing my front hub, the brake rotor retaining bolt completely striped, forcing me to break out the drill. :twisted: Shortly after deciding that I wouldn't waste my good drill bits when I had 2 crappy ones of the correct size in my toolbox, the crappy bit broke off in the bolt and a piece shot by my head at what look like mach 3. I got real luck that it didn't fly towards my face, so wear saftey glasses.


I thought I should include the classic RJ breaking stuff on his car shot.




Anyway, After I pulled off the hub with the rotor still attatched to it, it was easy to drill through from the other side with a quality drill bit to finish the job.

holy crap dude, way to go. :lol: IF you put those things back in, don't tighten them!

Honda does that shit too. I just just an impact driver. Works everytime.

better idea: throw the worthless bolts in the trash

Bosch bits are awesome, I highly reccomend them. Expensive as crap but they rarely brake, stay sharp a long time, and are hard.

Also, just as an FYI to those that don't know, when drilling through anything metal the proper technique is slow RPM's on the drill and heavy pressure. Speed in metal generates heat, and heat will kill a bit very quickly. Also, go to the hardware and get a small bottle of cutting lube and use it, makes a world of difference!

i was just wondering that, would you use any 'wet drilling' techniques? what kind of stuff would you use?

Cutting oil, NOT WD40. I use some stuff called Tap Free, but any oil used for lubbing up Tap and Die sets works great when drilling metal.

Or you could use Cocoa Butter...

[HAULN-SS]

or 10W-40

just like WD-40 that just cools the bits and makes them slip, creating more heat, you want to aid in helping them CUT, which is why you use cutting oil.

MAC, MATCO, and Snap-On all have great drill bits. Any size over 1/4 in is guaranteed for life! Down side? Espensive!
