Tools 5-Piece Drill Bit Adapter Set Compatible with Festool Centrotec Chucks

I like these adapters very much. They're similar to the McMaster-Carr 3185A41 - 3185A54 adapters, only these have the hex end for Centrotec instead of for regular power bit holders. I especially like the included internal to external hex adapter to put over the Centrotec hex so that your wrench won't damage it when you tighten down on a drill bit. Having a removable belt clip so that you can carry the pouch on your belt without having to know where the pouch contents are by touch is nice also.I was motivated to buy this set because the Festool 492648 quick release bit holder that came with my drill (which holder never impressed me too much in the first place) finally stopped engaging the groove on power bits and was allowing them to drop. I didn't want to buy another after that one failed so I bought this set along with a  B000X1R26Q  Wera 889/4/1 K Rapidadaptor, hoping to use the 1/4" drill bit holder on the 1/4" hex shank. The adapter collets have 4 sides. I found that I had to round off the tips of the hex at the end so that the diameter everywhere is the diameter at the flats. Of course, to take proper advantage of the Centrotec reduced run-out, one should use a lathe for that, but I used a bench grinder, and it's close enough for driving screws & etc. With the Snappy hex socket, I have been able to tighten it enough not to slip so far. I might try adding some  B0002KKTIG  Loctite 640 retaining compound if I ever do get slippage. See one of my photos for the result.

Typical Good Quality Snappy Tools.My only beef is with Festool that refuses to provide a quick release 1/4” Hex Chuck, forcing me to buy duplicate drills and countersinks for my Festool Drills.

I am always hesitant buying third party parts. I absolutely love using my Festool drills but hate spending so much for their Centrotec drill bits. I took a chance with this set by Snappy. I have had no problems whatsoever. Excellent drilling sharpness and fit like a charm. I have no trouble recommending.

These seen well built. (Follow up: I tried to use these several times and they did not work. They fit into the drill okay, but they are greasy where the drill fits into the chuck, which makes the drill slip as soon as it gets some resistance. I tried cleaning off the grease, but they still slip. Rather then messing with them, it's easier to go to a regular chuck with a regular bit and just use that. Next I'm going to try the Festool set, which is what I should have done in the first place. More expensive, but I bet they work.)

I absolutely love these drill bits! they fit my Festool screw guns perfectly.

Got these to put into a CXS systainer and they are great, Snug snap-in fit. It's very nice to be able to swap out the drill bits with not only the same size, but also metrics if needed.

Nice set just make sure you tighten up all the bits before using.

Works well happy with product.
