With my hobby business, I drill literally hundreds of holes in a variety of softwoods, hardwoods and exotic woods each year. I have bought brad point bits from Grizzly tools, local box stores and from Amazon. All seemed acceptable. For my specific task, I need a bit that does not chip the face of the wood, and does not chip out on the back side of the wood when it goes through. If you have ever tried to drill through 3/16" thick osage orange with no backing board below the wood, you know that is a tall order to fill. I had gotten to a point that I literally started every hole with a forstner bit to keep from chipping the face of the wood, drilling about 1/8" deep, then switched to a brad point bit to finish the hole to keep from chipping out the back. Last weekend alone, I drilled no less than 240 holes. With switching bits, that equated to 480 holes. This week I received an order from Lee Valley tools of some "lipped brad point" bits. The idea is that the "lip" of the bit scores the wood before the bit begins to clear the stock. OH MY GOODNESS! Drilling my pilot holes for 1/4" bolts ... the bit seemed to just disappear into the hard woods with no pressure. Drilling the holes through 3/16" thick osage left no chip on top, or on the bottom of the material. I will try to get close up pics this weekend. Time will tell how long they remain so sharp, but I think I have found a new "go-to" drill bit for precise holes. http://www.leevalley.com/us/Wood/page.aspx?p=42247&cat=42240 If you are just boring rough holes through plywood or 2x material, it may not matter so much. When you need precision holes cut into a project that requires no chip or tear out... these things are amazing!
