A power tool question

I have some 4 x 4's left over from when my fence was built, and I want to use them for making a raised garden bed. I was all excited yesterday to get the holes drilled so I could thread pieces of rebar through them and have an 8" high frame.

No such luck, with my two charged cordless drill batteries, and my 3/4" drill bit, Mr W and I were able to drill exactly 1 and 1/2 holes before the batteries gave out. The drill is old (10 years) and the drill bit is part of an inexpensive set of about 20 that I bought when I moved into the house.

My questions are: Do these batteries get weaker over time? Can I buy replacements at a Home Depot type store? Also, are all drill bits created equal? Could I spend some money and get a good one that will stay sharp? I imagine the answers to these questions are all "yes", but was wondering if anyone who reads this blog has experience here. Thanks!


  1. Yes, batteries can lose their ability to hold a charge. You can look online to see if Home Depot carries spare batteries, or look online to see where you can buy them from. Do you have a corded drill? That's been more useful for me since batteries do die. Not sure about the bit question. 3/4 is big - must be a spade bit?

  2. Buying a better drill bit, such as a diamond cut one, would result in it staying sharper for a lot longer. You will also get a far better quality hole with less edge shearing

  3. Thanks, all. I think I shall buy a corded drill and a new bit as well. Jordan, yes, it's a spade bit.


Hi, sorry to make the humans do an extra step.
