Works very well

Received these yesterday and used a 3/8" socket today. The drill bit fits perfectly and stays in place with moderate torque on the screw. Love that Lettering on each collar seems well done considering only 9 holes are drilled.

Pros
  • Drill parts and accessories
Cons
  • Slightly torn

Bend drill, not immediately reusable

Not satisfied with this set. I found it bends the drill it was attached to so I ended up with egg shaped holes and due to poor design they bend around the drill in a set and won't come loose without loosening. Garbage. Look elsewhere if you are looking for quality.

Pros
  • Drill
Cons
  • I don't remember

Work slow but work great

Works great as intended and includes all popular sizes. Be careful when using this product, test for holes and take your time. The drill heats up, which causes it to expand and, when reused, can shift the stops. For this reason I drilled through the board. I love that it's a hinge rather than a set screw and that it's a better and cheaper option compared to a power drill.

Pros
  • Hex Shank Drill Bit
Cons
  • Crumpled Package
