I’m very limited on tools and y’all were kind enough to help me before. I need to buy a single 3/8” drill bit to use in a 1/2” drill. I need to drill a couple holes in a 1” x 1” square steel tubing and want to get a bit to do the job. Lots of options out there.

Thanks,
Robert

for a 1/2" hole you need 2 bits, pilot hole of 1/8 to 1/4" then the 1/2" hole.

just the 1/2" bit can be done if you go slow with it, use wd40 or blaster for lubricant/coolant.

pilot hole is better.

milwaukee or dewalt bits are good

Go to lowes and buy a 3/8 high speed drill bit .... like this one https://www.lowes.com/pd/CLE-LINE-3-8-in-Black-and-GoldHSS-JobberDrill-Bit-with-3-Flats/1003166970

If you can find you some TapMagic cutting oil you want have any problems

Thanks for all the help!
