Apex 37228 Three Square Needle File Cut 2 4 Inch

Product Description

The APEX 37228 is a three-square needle file designed for precision material removal in tight spaces and on hard-to-reach surfaces. Built from steel with a Cut 2 (second-cut) profile, it delivers a balance of stock removal and surface finish suited to detailed filing work. At 3.94 inches overall length and 0.11 inches wide, this file is sized for intricate hand work on metal parts, burrs, slots, and angular grooves. The triangular cross-section creates three filing faces and three cutting edges, making it effective for filing internal angles, notches, and V-grooves. It is hard stamped for durable, permanent identification.

This needle file is used across metalworking, fabrication, toolmaking, electrical, HVAC, and plumbing trades wherever close-tolerance hand filing is required. Its compact size fits into confined areas where standard files cannot reach, making it a common tool for deburring pipe ends, cleaning threads, fitting components, and refining edges on brackets or sheet metal. Suitable for both shop bench work and field service applications.

Key Features

• Three-square (triangular) cross-section provides three flat filing faces and three sharp cutting edges

Compatibility

Designed as a general-purpose three-square needle file suitable for hand filing applications on steel, iron, and similar metals in trade and shop environments.

Installation Notes

Needle files are hand tools requiring no power source or special installation. Always secure the workpiece before filing to maintain control and accuracy. Wear appropriate eye protection when filing metal to guard against fine chips and debris. Inspect the file tang and handle fit before use; a loose or missing handle increases the risk of injury.
