BEST HINGE BIT! Self-Centering Drill and Drive Hinge and Bracket Tool from Montana Brand Tools 

Correct, both terms refer to the same tool

Hey Stillnapie, just following up for the RU-vid world here- you spoke with our salesman, and we sent out a replacement. We take pride in honoring our Limited Lifetime Warranty, so give us a call if you ever have any issues. We WILL make it right!

That depends what size screws you are using. If it is a standard door hinge in a home, it is likely a #10 screw. Most hinges will have a number on the packaging. We are definitely happy to help, but we don't check our RU-vid as often as we would like to! If you need further assistance, we are a lot quicker to answer questions via email at Sales@MontanaBrandTools.com or phone at 406-528-four three five zero.

As long as the insert and body are concentric, a little space and wiggle is fine. The drill point is centered in the coned point, and your pressure on the drill will keep it in the chamfered hole. This "slop" is also fine in the 4-in-1 version for the same reason- the drill point is centered and pulls the drill straight through the cut.

@@MontanaBrandTools If there is room for the bit to walk, the hole will not always be centered. Its not just about drilling a hole inside of a circle. If I buy a self-centering bit, instead of "eyeing" it myself, I expect the tool to cener the hole, which will not consistently happen in if the bit can walk across grain.

@@GlenGray-r4i Now I understand where you are coming from- the space between the inside of the point of the chamfered drill guide and the outside of the cutting lips of the drill. (Pardon me, I thought you were talking about the entirety of the flippable insert, which does have some wiggle.) That clearance space is tight on our Self-Centering Drill and Driver. You will be able to put your hardware exactly where you want it, and the holes you drill will follow, centered in the hardware. It is not something we have ever had negative feedback on as the tool performs very well with great accuracy. My apologies for not understanding you, but I believe your concern is covered by properly engineering the point of our tool. You should take it for a spin and see for yourself!

True that most of the Montana line has been around a while. We invented the hex shank system back in the day, as well as a host of tools that work with it and dozens of original patents that many are now copying after they expired. It’s not always about coming out with the newest thing. Manufacturing a high quality and consistent product is an innovative feat in itself in the current state of the world. Have you noticed the quality recently slipping in many other products you have used over the years? Have you tried our tools? We strive to break that trend, keep it high quality and maintain American job availability here in Montana. That said, our parent company makes industrial and aerospace-grade precision cutting tools. We have had rapid growth in the last year and invested heavily in technology at our facility (robotics, advanced coatings, mass printing, packaging machines, etc.) that strengthens our company, increases quality, expands volume, boosts safety and provided dozens of additional jobs in 2022. We aren’t good at talking about these things on social media, and some of it is top secret due to the nature of our partnerships, but we will try to show more of the innovation behind the scenes here. If you have innovative ideas, we are hiring at RockyMountainTwist.com .
