B00438 - Cobalt Steel, 3/8" Four Flute Rough Mill Router Bit

The Castle Cobalt High Speed Steel 4 flute bit works well routing most solid woods. (If you work with dense hardwoods such as hickory, you will want to use our Solid Carbide bit - B00338.) The rough mill design routs a consistently clean and splinter free pocket.  This bit is 2.5" in length.
