Customer Questions & Answers

I bought this bit but Home Depot does not carry a drill that will fit. Where do I find a drill works with this size?

Asked by: eric
Standard Drill Motors come with "chucks" that will handle 'bits' of either 1/4" OR 1/2". Your 5/8" 'bit' will require an 'industrial' size Chuck...Big money. The normal "work around" for this problem is to buy a 5/8 Drill bit with a 1/2" shank. OR Drill a 1/2 inch Hole and use a "REAMER" to enlarge the hole to 5/8. Home Depot or Lowes should sell "Reamers". They are a tapered tool that fits into a 1/2" Drill motor, the farther you push it into the hole the larger the hole becomes.
