Lowes usually has a Bosch 1/4" 2 flute upcut spiral router bit in solid carbide that I have used several of up, and in MDF, nothing but solid carbide will hold an edge for long. This bit has a 1 inch and small change flute length, so can be run full depth in 3/4" MDF in one pass. And it can do a straight plunge too. Unforch, at the rpms either of our machines can make, MDF cuts with a lot of fuzz left at the edges. The brazed bit, not being as sharp, exacerbates this, a lot. :( The HSS bit will rapidly dull in MDF even if originally very sharp. It runs slightly more than a $20 bill IIRC. There are no doubt better bits, but you can put one of those in hand in an hour or less depending on how close the nearest Lowes is. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
