Onsrud 56-628 Square End Router Bit 1/4 in Solid Carbide

Product Description

The ONSRUD 56-628 is a 2-flute, square end, double edge solid carbide router bit designed for high-speed material removal in plastic routing applications. The cutter measures 0.25 inches in diameter with a 1.25-inch length of cut and a 4-inch overall length. The 0.25-inch shank provides compatibility with standard collet systems. Straight flute geometry and right-hand cutting direction produce clean, accurate cuts in a wide range of thermoplastic materials. This bit is suited for CNC routing operations and is installed by machining professionals and fabricators working with plastic sheet goods and profiles.

The ONSRUD 56-628 is intended for use on hard thermoplastics in both production and prototype environments. It is well-suited for CNC router tables handling sheet or profile stock. The straight flute design helps maintain edge quality when routing plastics that are sensitive to heat buildup. The double edge configuration provides two usable cutting edges per pass.

Installation Notes

Install and remove router bits only with the spindle powered off and locked out per applicable machine safety procedures. Seat the shank fully into the collet and torque the collet nut according to the router manufacturer's specifications. Verify spindle RPM is appropriate for the cutter diameter and workpiece material before operation. Inspect the cutting edges for chips or wear before each use.
