Questions & Answers

There appears to be an angle to the cutting edges. What are the chances of the sides of the mortise being perpendicular to the bottom?

A perpendicular angle is created between the sides. Cutting is done with a square mortise, but the cutter is angled back for a slight shearing cut.

How is the bearing sized? Is it 5/8" or 1/2"?

cutter has the same size as the bearing, which is 1/2 inch

A smalltambour door is on my mind for which I plan to use this bit for cutting. There are basically two types of dadoes curved and straight. Does this seem like the best decision for me?

My recommended bit for mortising is a Dado cleaning router bit which leaves a nice flat bottom in your mortise. It is nearly identical to the bit down, but with an approximate size cut of 3/8".

Does this bit work well for inserting hinges into doors?

As long as you use a template to guide the process, it will work well. However, if you try to use it freehand, you will need to use your chisel to clean up the edges or you will have visible overcuts if you are not skilled.

You hit the nail on the head

5/5

". After I bought the new bit, I hit a nail when I was mortising the first hole. When I checked the carbide, there were no chips, so I continued to go with it. I was pleasantly surprised at how well it worked. Thanks for taking the time to let me know! The majority of Chinese carbide chips are produced by looking at them in the wrong way. The CMT bits I buy in the future will be more than enough.

It has a very smooth cut

5/5

I bought this as a replacement for a hinge jig bit that came with the Immediately after cutting it, that bit started to burn wood. Using this bit was like butter cutting through the wood. When I need this brand again, I will buy it again. As of yet, we cannot rate its durability and longevity, but we are expecting it to be very good.

Cutting patterns with this bit is a breeze

5/5

I had to install several mortise locks that were unusually sized, and the templates this bit provided enabled a simple and professional installation process.

CMT bits are top notch, and I have never had a problem with them

5/5

I have used CMT bits for years without having a problem. I used this one to mount door hinges, and it took my time a lot easier than using hammer and chisel, ensuring that the depth of the hole was accurate from the beginning.
