Apex 21853 Round File 0.312 in Bastard Cut 8 in

Product Description

The APEX 21853 is a round file designed for shaping, smoothing, and deburring metal, wood, and similar materials in trade and workshop applications. It features a 0.312-inch diameter with a bastard cut and a single-cut edge that tapers slightly toward the point, making it effective for enlarging holes, rounding internal curves, and finishing concave surfaces. The 8-inch working length provides good control for hand-filing tasks. Hard stamped markings identify the file specifications at a glance. The steel construction delivers the hardness needed for consistent material removal across repeated use cycles.

This file is suited for use in HVAC, plumbing, electrical, and general mechanical trades wherever metal or other materials require hand-filing. Typical applications include cleaning burrs from cut pipe, refining drilled holes, and shaping conduit knockout edges. It is equally useful in fabrication shops and field service environments where precision hand-tool work is routine.

Key Features

• Bastard cut with single-cut edge for moderate material removal and controlled finishing
• Tapered profile toward the point for access to tight curves and narrow openings
• 0.312-inch diameter round cross-section for consistent contact on concave surfaces
• 8-inch file length suitable for general hand-filing tasks
• Hard stamped markings for durable identification
• Steel construction for lasting hardness and cutting performance

Compatibility

Designed as a general-purpose round file suitable for hand-filing tasks on metal, wood, and similar materials in trade and workshop settings.

Installation Notes

Round files are used by hand without power tools and require no special installation. Always use a properly fitted handle when working with the file to maintain control and reduce the risk of injury from the tang. Inspect the file for cracks or damage before use. Keep the file clean and dry to maintain cutting performance.
