About EFFICERE 8-Piece 1/2” Shank Silver and Deming Drill Bit Set
80% appreciated its precise drilling accuracy, though 20% experienced deviation
The drill bits worked exceptionally well. I didn't even notice when I went all the way through the piece and was drilling through the hardened steel of my drill press clamp, which shows the accuracy of the jobber-drill-bits.
My drill press shook apart because the cutting edges of both bits were out of center.
79% liked its long-lasting durability, but 21% experienced frequent breakage
I found the drill bits to be lacking in durability and quality.
82% liked the comfortable grip design, while 18% found it slippery
Both bits' cutting edges are off-center, making me think my drill press will shake apart.
86% praised for its versatility in drilling various materials, though 14% had difficulty with metal
I had difficulty cutting into lightweight c-channel and struggled to get through receiver hitch material with the bits I had. However, the cobalt bits I purchased had no problem drilling smaller holes. Based on my experience, I can say that the bits have their limitations.
