V-Flute Carbide Router Bit
The Onsrud 56-122 is a solid carbide router bit with a straight V-flute geometry. It is built for routing composite sheets, foam blocks and hard plastic panels. The cutter diameter is 3/8 inch and the tool is sold new.
CNC operators cutting soft sheet goods
This bit suits CNC operators and fabricators who need clean V-grooves or through-cuts in abrasive composites and rigid foam. It is not for buyers who need a drill bit for metal or a standard twist drill for wood. The design does not support general-purpose hole drilling in steel.
3/8 inch cutter diameter
The 3/8 inch cutter diameter is the single dimension that determines whether this bit fits the programmed tool path and the collet or holder in use. Match this figure to the job specification before ordering.

Questions about this item
How often will the carbide V-flute edges need resharpening when routing composite and foam?
Carbide retains its edge far longer than high-speed steel, so resharpening intervals are measured in hundreds of metres of cut rather than tens.
What stops the 56-122 from cutting deeper in a single pass?
The 3/8 inch cutter diameter and 7/8 inch flute length limit chip clearance, so the bit stalls before the shank reaches full depth.
Does the solid carbide body run hot enough to melt hard plastic during continuous routing?
Carbide conducts heat away from the tip, and the straight V-flute ejects chips efficiently, keeping the workpiece below melting point.
