KEENTECHRouter Bits, Carbide Tipped 45 Degree Chamfer Router Bit for Edge Forming, Industrial Grade Blue Cutting Tools for Woodworking (1/2 Inch Shank x 1/2 Inch Bevel x 1/2 Inch Depth, KT02030808)

This bit works great. Using it to bevel the end cuts on v groove pine paneling.

I needed to rout edges on PVC. I’d never worked with PVC lumber before. This bit cut accurately and fast. Now that I’ve finished the job (about 100 linear feet) it looks and performs like new.

After edge profiling nearly 500 sign blanks to a 1/2" depth, it's still sharp and doing and excellent job.

I tried two of these. Both failed on first use.First one had the shaft bend first time I used it on a practice piece. It was 1/4" shaft and I tried a moderately deep cut but it would not have been too deep for a Bosch bit.I returned the first one and ordered a replacement. I was extremely careful to go slowly with increasing the height on the router table raising only 1/32" each pass. On the last pass, the carbide edge shattered. I didn't notice until after the cut and it made a mess out of an 8/4 piece of cherry that cost $50. Fortunately, I was able to clean up the work piece with a hand plane. Also, the bearing disappeared. Good thing I had the fence set up as a backup.The description says 3/4" depth of cut, which is not correct.I returned the second one for a refund.

I have dozens of feet of shelving to build, and this 45-degree chamfer bit looks like it will do a solid job of taking the sharp edges off the top surface. This shape of bit was missing in the starter kit of assorted bits I have as a beginner to this work, so I'm glad to get a bit for more advanced work. I'll be testing this on fir planks and see how it goes. The quality of tungsten carbide blade looks right up there, withsmooth and balanced surfaces.Review of KEENTECH 55/64" (Dia.) 45 Degree Chamfer Bit with 1/4" Shank, 1/4" Bevel Length (KT02030404)

I freely admit that there are two standards in my workshop; that result that should be attainable and that result that actually occurs. This router bit is sharp, well made and has a guide bearing that is supposed to keep me out of trouble and give me a great edge. It is a good tool for the cost and the defects in my projects are because of me, not the tool.

I got the 7/8" bevel length to cut a toy wooden sword out of a 1.25" thick piece of wood. Worked well. I used it on my cordless Dewalt - I just had to take off the guard because this bit is too wide.

In my 30 years of woodworking I have never seen this happen. The bearing on a brand new router bit was frozen - and spun off at high speed, bounced off the garage door and hit my pinkie finger. Luckily a very minor bruise and i always wear safety glasses. In the future i will certainly check to make sure the bearing is spinning before i use it. Yes, this has never happened before, but clearly it can happen and i have now learned that the hard way.of course after it spun off, it grooved the exotic african padauk wood art piece. To remedy it i will have to cut off the end of the work and route it again. My only suggestion to the mfg is that quality control is clearly lacking in my opinion.val

I have been in the business for many many years and I have never been more disappointed with a router bit. The carbide is very poor. Less than 6” into using it on some Birch hardwood and the carbide cracked. Never buying these bits again. 🤮
