Great racket with extra extra length!

When I received this drill I discovered that they had actually sent me a 12 inch long drill. Thanks very much! The only problem is that the end of the drill is round and will slip off, so all you have to do is use a grinder and create 3 flat sides on that end. Problem solved. Great bit and just what I needed.

Pros
  • Last 50 percent longer than HSS
Cons
  • Some errors

Need a 12 inch bit?

I needed a 12" drill bit. Couldn't find it at Revain but started reading reviews of this "SIX Incher" and found so many people saying they had the Twelve Incher I just ordered it. Yes, 12 inches. Oooooh, that's it. Three stars to get attention so the description text can be corrected. Just arrived, will follow up when I use it. Only this thing has a job, it has to survive. Hope.

Pros
  • Easier drilling, less heat and longer drill bit life
Cons
  • Only available in black

Not the best long drill but does the job.

Not the best long chisel, but gets the job done. The bit shank flexes under light pressure - less than 15 pounds, allowing the bit to go through whatever material you're drilling. I went through 1/16" mild steel (not hardened) and it took me quite a bit of effort to even cut through it. I was afraid the drill would break, but after some patience it finally cut through. Maybe there are better drills. a bit there but I couldn't find them at that price. I will spend a little more next time and get

Pros
  • Speed Spiral design for three times faster drilling than standard chisels
Cons
  • Not bad, but...
