Excellent value for a regular drill

These drills are suitable for general home use. 1/8 inch seems to be a common size for most projects and the most commonly used bit is a breakable bit (for such a small size) and it's worth having a set like this on hand. It was a good deal.

Pros
  • Good
Cons
  • Obsolete

Exceeded Expectations

bought the pack because there were a lot of holes to drill in the aluminum tube. thought and hoped to get 4 or 5 holes per bit. I changed the first cutter after about 25 holes, and then it really wasn't necessary. Great beats for the price! I very, very rarely write reviews because these drills are so good.

Pros
  • Impressive
Cons
  • Drill Pack

Great cut when you are perfectly straight

These bits cut great when you are straight. The holes I need to drill are slanted and all of these bits are broken in half. The cutting edge of these bits is sharp and moves material with wavy chips, but cannot work at an angle or with any type of sticking. Maybe the carbon is too high causing the bit to break in half.

Pros
  • Great product
Cons
  • Something different
