Onsrud 56-162L Router Bit 1/2in 2 Flute Solid Carbide

Product Description

The ONSRUD 56-162L is a 2-flute, square end, double edge router bit designed for cutting hard and semi-rigid materials in CNC and manual routing applications. Built from solid carbide, the bit measures 0.5 inches in cutter diameter with a 1-inch length of cut and a 3-inch overall length. The 0.5-inch shank diameter provides secure chuck engagement. Left-hand cutting geometry suits specific fixturing setups and climb-cutting operations where surface finish or material holddown demands it. This bit is suited for use by machinists, fabricators, and shop technicians working with plastics, composites, and solid surface materials.

The 56-162L is intended for use on a broad range of hard materials including ABS, acetal, acrylic, fiberglass, foam, nylon, polyvinylchloride, phenolic, and solid surfaces. It fits standard CNC router spindles and handheld router platforms accepting a 0.5-inch collet. Typical applications include profile routing, edge trimming, and through-cutting of sheet and plate stock in fabrication and production environments. The double edge router style allows efficient chip evacuation during straight-flute cuts.

Key Features

• Solid carbide construction for durability and edge retention in hard materials
• Square end geometry for flat-bottomed cuts and clean edge profiles
• Left-hand cutting direction suited for specific climb-cut and fixturing applications
• Double edge, straight flute design promotes chip clearance during through-cuts
• 0.5-inch shank diameter fits standard half-inch collets on CNC and handheld routers
• No pilot - suitable for freehand and template-guided routing setups

Compatibility

Designed for use on ABS, acetal, acrylic, fiberglass, foam, nylon, polyvinylchloride, phenolic, and solid surface materials. Fits any router spindle or collet accepting a 0.5-inch shank. Part of the ONSRUD 56-000P series.

Installation Notes

Installation should be performed by a qualified machinist or fabricator. Power down and lock out the router or CNC spindle before inserting or removing the bit. Insert the shank fully into the collet to the manufacturer-specified minimum engagement depth before tightening. Verify spindle rotation direction matches the left-hand cutting geometry of this bit before operation, as running a left-hand bit on a standard right-hand spindle will not produce a cutting action.
