Onsrud 56-082L Square End Router Bit 1/4 Inch Solid Carbide

Product Description

The ONSRUD 56-082L is a 2-flute, square end, double edge router bit designed for cutting hard materials in industrial and production routing applications. Built from solid carbide, this bit delivers durability and edge retention in demanding applications. It features a 1/4 inch cutter diameter, 3/4 inch length of cut, and a 2.5 inch overall length. The left-hand cutting direction suits specific climb-cutting setups and specialized CNC or handheld routing configurations. Installed by machinists, fabricators, and CNC operators, it performs reliably across a wide range of non-metallic materials.

This router bit is suited for use on plastics, composites, and solid surface materials including ABS, acetal, acrylic, fiberglass, foam, nylon, polyvinylchloride, phenolic, and solid surfaces. Its double edge router style makes it effective in production environments where consistent, repeatable cuts are required. The 1/4 inch shank diameter fits standard collets used in both handheld routers and CNC spindles operating at appropriate speeds for carbide tooling.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• Left-hand cutting direction for climb-cut or reverse-rotation applications
• Square end geometry delivers clean, flat-bottomed cuts
• Double edge router style for efficient material removal
• 2-flute straight flute design reduces chip buildup during cutting
• No pilot bearing - used for freehand and guided fixture routing

Compatibility

Compatible with routing applications involving ABS, acetal, acrylic, fiberglass, foam, nylon, polyvinylchloride, phenolic, and solid surfaces. Part of the ONSRUD 56-000P series. Fits standard 1/4 inch collets.

Installation Notes

This bit should be installed by a qualified machinist or CNC operator familiar with carbide tooling requirements. Ensure the router or spindle is fully powered down and locked out before installing or removing the bit. Verify collet condition and torque the collet nut to the tool manufacturer specifications before operation. Left-hand cut bits require confirmation of spindle rotation direction before use to prevent improper engagement and tool damage.
