I use the same milling cutter in the bar on different positions (rotating 180 degrees) drilled two holes, the diameter difference of 20 wire... I wonder if the problem of the knife is still the problem of the machine tool
Can be replaced (in small quantities), and batch processing is not recommended because it is uneconomical!!1, most of the milling cutters are now hard alloy, and the radial force is relatively smaller than the drill bit, so there is no swing problem,2, cutter side blade is belt angle, the bit is cutting edge, so the diameter of the drill bit is easy to maintain its stability, but is not to say that the cutter at all not after all and not doing mud cutter wear, not so fast, but when batch processing is recommended to use the drill bit.3, to be exact, it should be less expensive than the drill bit, but batch processing is a single piece cost, which is a bit more cost-effective!!4, two edged cutter abroad called slot drill, so they are sometimes used when using the drill bit!!
Two edged cutter is can drill, but can not replace the drill bit.For one thing, the milling cutter does not have a center edge and is easy to swing when it is drilled.Two, the outside of the milling cutter is a cutting edge, and the outside of the bit is a guide blade, so the hole drilled out of the cutter is not standard.Three, the cost of milling is higher than the cost of the drill.
