This premium solid carbide bit cuts dadoes with crisp, clean edges on both sides of the dado. The downward spiral forces the chips down into the groove, eliminating the tendency for wood fibers to chip out the face. Also works great for cutouts and edgework. 1/4'' shank.
Application: Grooves and dadoes in single-sided veneers and laminates.
Freud's solid carbide down spiral bits are ideal for smooth, chip-free routing where chip removal is not a problem.
Cuts all composition materials, plywoods, hardwoods, and softwoods.
Use on CNC and other automatic routers as well as hand-held and table-mounted portable routers.
Had a special use for the down cut bit - was engraving signs with my CNC Piranha using a "sticky back" Vellum so I could spray paint the letters. Getting a fair amount of lifting and tearing of the protective vellum with an upcut spiral bit, I tried the downcut. The downward spiral seemed to cut the vellum better, and since I was only cutting to 0.03 depth, getting rid of the chips was not an issue. On a general note, Freud bits, in general, are very good for all of my CNC work, from 1/16" to 1". They stay sharp and always cut smoothly.
The first time I used the bit in a CNC mavhine cutting 1/8 inch deep into white oak and the bit traveling at 30 feet per minute and spinning at 16,000 RPM, the bit snapped. I was vety disappointed that it did not perform as I expected.
