Apex 12084 Round File 0.375 in Smooth Cut

Product Description

The APEX 12084 is a smooth-cut round file designed for precision material removal and surface finishing on metal, plastic, and similar materials. Measuring 0.375 inches in diameter and 10 inches in working length, this single-cut file features a slight taper toward the point, allowing techs and tradespeople to work inside bores, enlarge holes, and clean up curved profiles with controlled, fine-cutting action. The smooth cut rating means fewer, finer teeth per inch, producing a refined surface finish suited for final-pass filing and deburring where a coarser cut would leave too much roughness. At 0.3 pounds, it is light enough for extended single-hand use. Constructed from steel with a hard-stamped marking for durable identification.

This round file is used across mechanical, plumbing, HVAC, and electrical trades wherever fitted parts require light material removal or edge cleanup before assembly. Common applications include enlarging conduit knockouts, cleaning burrs from pipe ends, smoothing irregular edges on sheet metal brackets, and fitting mechanical components to close tolerances. Its round cross-section and tapered profile make it well-suited for slotted holes, circular openings, and contoured surfaces that flat or half-round files cannot reach effectively.

Key Features

• Smooth-cut single-cut teeth for fine finishing and deburring passes
• 0.375 inch diameter round profile with slight taper toward the point
• 10 inch working length for controlled reach in confined spaces
• Steel construction with hard-stamped part marking for lasting identification
• 0.35 inch thickness throughout the body for consistent cross-section grip in guides or fixtures
• Lightweight at 0.3 pounds for comfortable extended use

Compatibility

Designed as a general-purpose round file suitable for use on steel, aluminum, brass, plastic, and similar machinable materials in trade and light industrial applications.

Installation Notes

Round files of this type are hand tools requiring no power source, but proper handle fitment is recommended before use to prevent tang injuries. Secure the workpiece in a vise or clamp before filing to maintain control and achieve consistent material removal. File in one direction with moderate, even pressure and lift on the return stroke to prolong tooth life. Inspect the file regularly for clogging and use a file card or brush to clear embedded material.
