Just too soft. Best in Drills

Used about 4 times. It's too soft for steel like angles. For the price listed for a 1" bit I would think that with the right cutting oil it would last a while. It just wasn't for me. Not sure if I just bought the wrong bit or what but it definitely has metals listed as drillable in the description and I'm after about the 3rd or 4th hole it was made for , ungodly amounts of coolant used in vain at an angle of 1/8 inch.

Pros
  • Power Tool Parts & Accessories
Cons
  • Slightly Crumpled

Bent Shank to 5/8 " Bit

I bought a 29 piece set that works great! But I needed a 5/8" bit to add to my set. Firstly, I took a chance as the set worked so well. This 5/8" drill bit bent on the shank the first time it was used in a power drill, rendering it unusable. It started to wobble when the first hole was drilled in a 1/4 inch mild steel plate. Using cutting fluid, I started by drilling a 1/8" pilot hole and worked my way down to 1/2" before using 5/8". .

Pros
  • Power & Hand Tools
Cons
  • Something Else

Received broken in half. No delivery problem.

When I receive a damaged product, it is usually due to a delivery issue. This one confused me. The packaging it came in was perfect, just like the original packaging in pic 1. Somehow my new heavy duty 5/8 drill bit broke in half. See Figure 2. If you put the two pieces together, you can clearly see that there are no large pieces missing in the area where the crack occurred. However, these fragments are nowhere to be found. I can only assume that the packaging was damaged through negligence…

Pros
  • Drill
Cons
  • Slightly torn
