CMT812.127.11B Pattern Bit with Bearing, 1/4-Inch Shank, 1/2-Inch Diameter, Carbide-Tipped

Consistently shape bits and long lasting

I needed a flush cutting pattern bit to make a copy my Festool MFT top. (The MFT top has a series of precise 20mm holes and my existing top was going to be used as the pattern)In the past I had used a Freud bit which worked fine but I was making a new top so I decided to purchase a new bit. However, the CMT bit is slightly undersized compared to the bearing by about .005" which is enough so that my metal dogs will not fit into the holes. This usually would not be a problem with most patterns but in my case it would not workI also tried the Amana and Whiteside bit - same thing. (Whiteside says they deliberately undersize the bit so that it will not cut into the pattern)I ended up buying another Freud bit - and it is exact - the bearing diameter matches the bit diameterSo if your looking for an exact 1/2" flush cutting pattern bit - buy the Freud

I used this bit to cut six large parts (maybe 85 feet of cutting overall) before the patterning bit on top separated from the cutting area. Fortunately, it was partway through the last piece. Otherwise, it stayed sharp, with only an occasional cleaning needed. I'm a novice woodworker and probably treated it pretty harshly.

Perfect. Sharp. Reliable and did exactly what I needed. Buy a set of them. Better price and much better than the Chinese bits.

Whats to say, a router bit is a router bit. I have always had good luck and good use from CMT bits. Price on Amazon is very good.

Typical CMT quality in router bits. Flawless operation. Super fast shipping.

The cutter seems to dull rather quickly. Also, the guide bearing will move around if you don't verify the tightness of the locking ring. Mine was shipped with it loose and almost cost me my workpiece. It isn't all bad. You just have to take it a little slower than normal.

I ordered this Router bit to cut out some doors for my bulk head on my boat. Once we got them aligned, we set the router to the appropriate length. We drilled a hole, and started to make our cuts. Great bit for our use.

Per tagliare taglia ma il cuscinetto a volte risale il gambo della fresa impedendo un uso agevole e senza pensieri di eventuali sagome, quando accade e non ci si accorge si rovina pezzo e sagoma...
