Freud 12-152: 3/4 (Dia.) Double Flute Straight Bit (Eclipse Grind) Red

Go through the material slowly.

When I first opened the box from Amazon, the bit had escaped from its thin plastic packaging and Im guessing it had been tossed around inside the box during shipping. Amazon gets a score of zero for their packaging on this one, and Freud certainly could do a better job on their part of the packaging. Other manufacturers actually ship their its in plastic or wooden boxes. Amazingly, the bit seemed fine. You cant use it to make plunge cuts because the cutters dont extend all the way to the center. Im sure thats obvious to someone with experience than I had before I bought this bit, but it wasnt clear to me until I tried to make my first plunge cut and couldnt get it to cut any deeper than about 1/16. But I suppose most people would use a drill press and Forstner bit to make this size plunge cut anyway. I mostly use this bit to cut clean circles after using my jigsaw to cut within about 1/8 of the line. The bit should also work well with a jig to flatten boards, as long as you dont need to plunge-cut. I havent used it yet for that. What I like: * very sharp * heavy-duty * seems very high-quality What I dont like: * Freuds packaging sucks * cant do plunge cuts * a smaller diameter bit would have served me just as well (but that was my mistake) Given what I know now, I absolutely did not need this router bit. I might even go so far as to say it proves the buy the biggest bit you can afford rule-of-thumb wrong. Although I didnt really need it, its still a good bit. But in general I would recommend against buying this bit unless you already own several dozen 1/2 shank router bits (including straight and spiral/compression bits) and not one of them is suitable for the job.

Freud bits are designed and precision machined in Italy - and they really are works of art. They plunge quickly, clear chips effortlessly and run through hardwood with ease. Im sure there are other fine bits out there, but for the value and at this price, I believe its no contest. If youre cutting dados, planing or jointing, you will be thrilled with these bits. Pros: • Sharp and removes chips fast • Designed for quick plunges • Delivers crisp clean edges • Hardened steel stays sharp longer than competition • 1/2 shanks nearly eliminate chatter Cons: • Expensive - but worth every penny • They are nearly impossible to remove from the packaging Tips To Remove From Packaging: • Wear Gloves! I mean it - these are as sharp as an ER scalpel. • Firmly grasp the flat (non-sharp) sides and wiggle the bit back and forth while pulling upward • Do not use pliers, channel locks or your vise. You will scratch the heck out of your beautiful bit • When storing in the packaging, only insert about 1/4 to make it simple to remove in the future! Usage Tip: • To avoid burning the wood when using the larger diameter bits, keep your router speed in the medium range or about 16,000rpm

I wanted to flatten the end of a 6x6 reclaimed oak beam. The beam was just the right height to secure in my benchs tail vice, and I made a jig to control the path of my 2.25 HP plunge router. I chose this bit because of its size (1 diameter-- takes off a decent amount but not too scary-big) and because of its cutting depth, which was necessary for me to reach the piece with my jig, while a more typical slab-flattening bit was not able to do. Anyway, it worked great for that purpose!

You do the math... this should produce a very tight fit. It does. Pliers were required to force the 1/4 shelf pins into the 15/64 holes. But, that was the recommendation of the shelf pin jig maker (Rockler). I dont think I will be making frequent changes to the shelf positions. (I have used the bit only one time to make 16 shelf pin holes so I wont comment on either longevity or value for money.)

I made a cherry table and used it to cut mortises as well as groves the length of 6 planks. I made groves 1/2 inch deep for splines to locate the planks. The total distance would be roughly 55 feet of cutting. The bit was still sharp and cut 10 mortises 1 3/4 inch deep on the ends of the table. I believe theres a possibility that those who broke the bits tried to cut the full depth in a single pass and at too great of a speed. To cut the full 1 3/4 inch mortise I made 3 passes, which is more or less standard procedure. Using digital calipers I checked the floating tenons that fit the mortises and they measured .373 inches. .375 is 3/8 of an inch.

Razor sharp as expected. High quality Freud tool. I see reviews here from people who used this for something other than what it is intended for- mortising, edge trimming etc. This 15/32 bit is used to cut perfectly sized dados for 12mm offshore plywood. I buy 1/2 inch birch plywood, finished one side at a great price from the lumber supply, but it is not 1/2 it is 0.46, or 12mm. Using a standard 1/2 bit to route dados for cabinet making etc makes a dado that is way too big, loose and sloppy. You can also get what is marketed as a bit specifically for undersized offshore plywood, but it is 31/64ths which is very close, but still makes a groove a little too wide (1/64th) if you do precision work. The 31/64 groove will fit together easily with that extra room but does not look good. If you use 12mm plywood and can route a perfectly straight dado, this is the one you want. Youll need to use a clamp to pop the joint together but with no slop or shadow line. For a particularly difficult joint, Ill sand the edges of the panel going into the dado slightly and it slides right in.

The trick with router bits is to make sure they are clean and sharp. They are pretty good from factory, but I found if you clean them and give them a good honing with a diamond file card before first use. They work much better. Also important to use correct router speed and feed rate. But dull dirty bits along with incorrect speed and feed lead to burning. When used properly these bits work great. Unfortunately some undersized plywood from foreign producers sold at big box stores are now thinner than 21/32nds. So these might even be a little over sized for those ply goods. So if you buy from large retailers, check the actual thickness of the sheet stock.

High quality bit.

so far so good
