Number of Flutes
HSS: High Speed Steel,
Typical applications in Non-Abrasive Plastic, Solid Wood & Aluminum
where keen edges perform best. High Speed Steel tools perform well
in hand routing applications where a tough core is necessary to
prevent tool breakage.
Carbide Tipped: Used
for a variety of applications in composite woods, hardwoods, abrasive
plastics and composites plastics to hard aluminum. Limited by geometry
in some applications due to the brazed nature of the tool. Carbide
Tipped tools work well in hand routing applications due to the tough
HSS core and hard carbide cutting edges.
Solid Carbide: Typically
used for widest variety of applications including man-made board,
solid wood, abrasive plastics, and some aluminum's. Solid Carbide
does not deflect allowing the tool to be fed at higher feedrates
than PCD or straight insert cutters decreasing cycle times. s typically.
Solid tools also have major edge keenness advantage thought only
possible in HSS until a few years ago.
- Offers a neutral cutting action - highest force
Upcut Flute -
Provides the best surface finish and allows for good chip extraction.
May cause part lifting if vacuum or fixturing is not sufficient
- Provides a downward force which helps eliminate part lifting.
Chip rewelding may occur if there is no space below the part for
Used for laminated materials, produces a good top and bottom finish
on the part
Number of Flutes
Single Flute -
Allows for larger chiploads in softer materials
- Allows for better part finish in harder materials
- Allows for an even better part finish in harder materials
the number of cutting edges increases, your feed rate should increase
to prevent burning and premature tool dulling
