Yonico Slot Cutter Router Bit 1/4-Inch Height X 3/8-Inch Depth 1/4-Inch Shank 14184q

Good router bit for making slots in the back of picture frames.

Nicely constructed, carbide cutters seemed uniform (least with a Mitutoyo caliper, didn’t bring out the mic to verify). However the bearing shielding popped loose and if I had to guess, it’s gonna seize up right quick with all that dust. Only got about 20 feet of cutting into OSB before this happened. Will try to contact Precision Bits and see if they warranty it (plus I’d like to grab a larger bearing to drop the depth of cut down to 1/4”).

It served the purpose well. For the price it’s well worth it. For a cleaner cut, do the full 3/8” cut in two passes instead one. Well it also depends on the material. Possibly three passes on some dense materials. I used it on pine wood and baltic birch plywood and all worked great.

I was looking for an alternative to the $60 router bit that Trex sells to put a groove on one side of their solid decking for your Edge piece. I could not get any internet information to confirm that this router bit would indeed work, so I thought I would make that confirmation for the next guy. So long as you set your height based on the distance of the factory groove from the bottom of the piece to the bottom of your groove this thing will work all day at 20% the cost of Trex name brand router bit

This bit is a waste of time and your money. The bit dulled on the first use. It cut through plywood with an extreme amount of tear out. It would not cut through hardwood. Save yourself some grief, and look to a different bit manufacturer.

Buy Freud or better

I was a little worried about using a 1/4 shank bit for slots without bending the shank. I set it up on a router table and adjusted the guide, and taking my time I slotted about 200 ft of softwood and 60 ft of hardwood and the bit worked fine. Some tearing of the softwood and a little scorching of the hardwood. Bit still looks good and my projects done.

The bit did exactly what I needed it to do. Great value I feel. But I’m not a router bit junky. Just buy what I need for specific tasks

This is a great bit for the money. Sharp and accurate. Dropped it a few times as well and the carbides havent chipped, so it seems pretty durable as well. Would buy again.

Ive had this for a couple of months now. Ive run about 100 board feet through it. It works well. I do every thing in two passes and clean it with fluid after 50 feet or so it get the pitch off. For the money Im pretty happt and will buy other bits from this brand.
