I mean I really don't need to say much as the quality of the white cutters speaks for itself. If you have read previous Whiteside product reviews you know I am very fond of Whiteside cutters. I also like Freud cutters and Infinity Cutting Tools, but Whiteside cutters are by far the best. They are simply superior in quality to the cutters of many other well-known brands. The handling of these bits is perfect. They hold an edge and stay sharp for a very long time. I usually buy cutting knives as needed. I've always carved spikes and slots for my shaker doors on a table saw. When I first did this I made a table saw mount to get the spikes perfect every time without fuss. That can take a long time. When a neighbor recently recruited me to build new cabinets for his kitchen, it required about 20 Shaker style doors. I have decided to adopt this installation bit. My god it made these doors easier and cut the assembly process in half at least. These bits went through 40 maple racks and 40 maple rails without fail. No burning and minimal tearing, they're still sharp and ready for the next project. So I tell you. If you're still buying those cheaper bits and haven't tried Whiteside yet, you should do so now. I also forgot to mention that the slotting cutter makes a perfect 7/32 groove for regular 1/4" plywood.
