Onsrud 61-040 Single Edge Router Bit 1/8 in Solid Carbide

Product Description

The ONSRUD 61-040 is a 1-flute, single edge straight router bit designed for precision cutting in aluminum and natural wood. Built from solid carbide, it delivers consistent chip evacuation and clean edge quality in single-pass operations. The bit features a 1/8 inch cutter diameter with a 1/2 inch length of cut, a 1/4 inch shank diameter, and a 2 inch overall length. The right-hand cutting direction suits standard router spindle rotation. This bit is well suited for CNC routing applications where tight tolerances and smooth finishes are required on non-ferrous metals and wood substrates.

The 61-040 is part of the ONSRUD 61-000 series, intended for use on aluminum and natural wood in production and job-shop CNC routing environments. Its compact 1/8 inch diameter makes it appropriate for detail work, narrow slot cutting, and contour routing where larger tooling cannot reach. It is typically installed and operated by machinists, CNC operators, and skilled woodworkers running routing equipment in industrial or shop settings.

Key Features

• Solid carbide construction for hardness and wear resistance on aluminum and wood
• 1-flute, single edge design promotes chip clearance in softer materials
• Square end geometry produces flat-bottomed cuts and sharp corners
• Right-hand cut direction for use with standard CNC router spindles
• 1/4 inch shank diameter fits common router collets without adapter
• Non-piloted design allows full freedom of movement along programmed toolpaths

Compatibility

Designed for use on aluminum and natural wood. Part of the ONSRUD 61-000 series of single edge solid carbide router bits.

Installation Notes

Installation should be performed by a qualified CNC operator or machinist with the spindle fully powered down and locked out before tool changes. Insert the shank fully into the collet to the recommended depth and torque the collet nut per the router manufacturer specifications. Confirm cutting direction matches spindle rotation before running the program. Inspect the bit for chipping or wear before each use, as carbide tooling can fail without visible warning when compromised.
