Apex 39971N Pillar File Safe Edges 10 Inch Steel

Product Description

The APEX 39971N is a 10-inch pillar file with safe edges, designed for controlled filing in tight channels, slots, and keyways where adjacent surfaces must not be marred. Constructed from steel with a hard-stamped marking style, this regular-style pillar file measures 9.84 inches in overall length, 0.69 inches wide, and 0.21 inches in height, giving it the narrow, flat profile that defines the pillar pattern. It is a hand tool used by machinists, pipefitters, millwrights, and trade professionals who require precision material removal in confined spaces.

The pillar file is suited to maintenance and fabrication work across HVAC, plumbing, electrical, and general mechanical trades. Its narrow body and safe edges make it effective for filing the walls of slots and grooves without damaging adjacent shoulders. Typical applications include deburring threaded pipe ends, cleaning up keyways on shafts, dressing metal brackets, and fitting components to close tolerances during installation or repair work.

Key Features

• Safe edges on both long sides prevent damage to adjacent surfaces during filing
• Pillar shape provides a narrow, flat profile sized for slots, keyways, and confined fits
• Steel construction for durability across ferrous and non-ferrous workpieces
• Hard-stamped marking style for clear, permanent pattern identification
• Regular style cut suitable for general-purpose metal removal and finishing
• Compact 0.69-inch width allows access in restricted work areas

Compatibility

Designed as a standard hand file for general trade and maintenance use where a 10-inch pillar profile with safe edges is required.

Installation Notes

A licensed or experienced tradesperson should use an appropriate file handle rated for the tang size before use to prevent hand injury. Secure the workpiece in a vise before filing to maintain control and prevent slipping. File on the forward stroke only and lift the file on the return stroke to preserve the cut teeth. Keep the file clean with a file card or brush to prevent pinning and maintain cutting efficiency.
