Reviews & Ratings for KAK .750 Multi Position Dimple Drill Jig — 33 reviews — Page 1

was able to dimple my barrel for my 308 with ease thanks then this jig it helped out a lot. provided bit was sharp enough to get it done

I've used this jig on 2 barrels so far and it has worked perfectly on both of them. One thing I really appreciated was the included spot drill. I'm a machinist and was very surprised to see the spot drill was made by YG. YG makes high quality cutting tools and have prices to match. The fact KAK includes a high quality tool when they could easily include a cheaper drill and save themselves a few bucks speaks volumes to their integrity as a company. Next time I dimple a barrel I'll definitely be using this jig and will probably pick up drill stop so once I have it set I never need to worry about drilling to deep again.

I didn't finish. This product is made from steel-and I have used it on 3 occasions thus far. I am very pleased with it. The drill bit has remained sharp, so have had no problem with any of the dimples

This jig has bee great. Beyond my expectations I highly recommend.

Great setup to dimple barrels. Drill is sharp, guide is robust, and allen wrench for alignment screw is included.

Does not work on my m and p sport 2. The holes where you put the set screw will not line up with the gas port. Do not recommend for the sport 2

Well made and worked great for my application. Use lube and go slow. Very reasonably priced as is usually the case for KAK

Works very well. I had no previous experience. I just followed the directions, drilled slowly and checks my dimples with the set screws. Very happy.

This tool does exactly what it’s supposed to, and that’s put a dimple perfectly opposite the gas port on a barrel. It does a good job of that and seems to be a well made part. However I prefer to square the gas block perfectly with the upper it’s going on. Using this tool there is still the potential for the block to be a hair off after installing the barrel, even when using a MI upper rod. This is probably an acceptable tolerance for plenty of people, and if you plan on selling the barrel or installing it on another upper later maybe you’d want the block aligned this way. Personally I install a barrel to go with an upper, and I like to perfectly square the block and upper together. I got this tool mostly to see how well I’ve done without one, and don’t find it necessary. I actually had to align the gas tube because it was pushing on one side from the block not being square with the upper. I like my gas tubes floating in the upper and interfacing perfectly with the gas key. Keep in mind that drilling nitride barrels can be very tough no matter what tool is used.

The brill bit works but i would recommend a spot facing bit to reduce the depth needed to catch the set screws.
