Easily removed a bad problem (16/07/2015)
I have removed some tough screws with aid of the drill press, and Kroil, heat, etc. I recently ran into a unique problem of a new rifle that had been stored for years, and the action screws were so tight, I couldn't remove the gun from the stock! After two day soak with Kroil, I was dreading the thought of having to drill out a screw to remove the action from the stock. I ordered this tool in the kit package. It is heavily built, comes with an assortment of magna-tip bits, and the heavy magna-tip adapter that comes with the kit is a must. If you already own an impact driver, buy the Brownell's adapter for the magna-tip bits. Two strikes had the screw loose, problem solved. I wish I had this years ago.
It came with no instructions, but it is simple enough. Place the appropriate bit that fits the screw in the tool, place it into the screw(or test on a bench if you've never used one of these like me), turn the tool according to the markings on the tool, and rap it with an appropriate hammer. As stated, "if it's going to come out, this will do it". Great tool!
With the good tight fitting bit, no damage to the screw head! I'm still surprised this screw didn't break.
Notice in my review, I have just purchased this tool, I haven't used it for many years to attest to durability, etc, so the categories are based on my initial assessment. Buy the kit, save time! Well worth the cost in my opinion.
