CO2135 1/8 in. x 2-3/4 in. Cobalt Drill Bit

CO2135 1/8 in. x 2-3/4 in. Cobalt Drill Bit

Q: I have to fasten 3 inch long bolts (5/16 head) into drywall/stud. Is this drill flute long enough to create a sufficient pilot holes?

Hmmm.... well, I would think if you anchored the shaft with the full 2 3/4 inch cutting screw exposed and sink it into the stud down to the chuck you might have a good pilot hole. The only thing that bothers me is that you said these are BOLTS not screws... so I don't know how much bite they will have to go that last 1/4 inch. so you may have to leave a bit of the shaft exposed to get the full 3" you will need. I hope that helps... hard to answer when I can't see what you are what you are working with. (I am a visual learner) ;) be safe and stay well.

Q: Would it work with a craftsman drill?

Thank you for your question. The CO2135 Cobalt drill Bit has a rounded shank. If your Craftsman drill accepts round shank bit, then it will work. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from M-F 7a-7p CST.
