Solid Carbide Router Bit

This solid carbide router bit features a downcut O-flute spiral geometry designed for clean edge finishes on soft plastics. The 1/4 inch cutter diameter and uncoated surface suit CNC routing and hand-held operations. It is built for material removal where upward chip evacuation is not required.

Plastics Fabrication and Sign Work

The downcut action presses chips downward, making it suited for thin sheet plastics, laminates and veneers where tear-out on the top surface must be avoided. Users needing aggressive chip clearance for thick aluminium or deep pocketing in hardwood should select an upcut or straight-flute alternative.

1/4 Inch Cutter Diameter

This single dimension determines whether the bit fits your collet and matches the programmed tool path. Verify the shank size and overall length against your machine and fixture before ordering.

Questions about this item

How does the 1/4 inch cutter diameter affect cut quality in soft plastic?

The 1/4 inch carbide cutter with O-flute downcut geometry shears soft plastic cleanly, pushing chips downward to prevent edge lifting and delivering a smooth bottom finish.

What shank standard does the 62-776 use and what collet size is required?

The bit uses a standard 1/4 inch shank, so it fits any 1/4 inch collet or chuck on a compatible router or CNC spindle.

What is the overall length and flute length of the 62-776 router bit?

The overall length is 41 mm and the flute length is 62 mm, giving enough reach for typical soft-plastic routing passes.
