Apex Tool Group Llc 21846NN Round Bastard File 6 Inches

Product Description

The APEX TOOL GROUP LLC 21846NN is a 6-inch Black Diamond round bastard file designed for filing circular openings and concave surfaces. It features a single-cut American pattern tooth configuration and tapers slightly toward the point, which allows controlled material removal in tight radii and curved profiles. At 0.24 pounds, this is a lightweight hand file suited for bench work and field use. Licensed HVAC techs, plumbers, and pipefitters reach for this file when dressing burrs from drilled or punched round holes, smoothing pipe ends, or fitting conduit knockouts.

The 21846NN is a general-purpose trade file appropriate for metalworking tasks across HVAC, plumbing, electrical, and light fabrication work. Its round cross-section and tapered profile make it especially useful when enlarging or cleaning up circular openings in sheet metal, conduit boxes, pipe flanges, or similar components. The single-cut pattern produces a smoother finish than double-cut files and is well suited to finishing passes rather than aggressive stock removal.

Key Features

• 6-inch length with slight taper toward the point for controlled filing in circular profiles
• Round cross-section targets circular openings and concave surfaces directly
• Single-cut American pattern delivers a smoother finish and finer control
• Black Diamond tooth finish provides consistent cutting performance
• Lightweight at 0.24 pounds for extended hand use without fatigue

Compatibility

Designed as a general-purpose round bastard file suitable for metalworking applications across HVAC, plumbing, electrical, and fabrication trades.

Installation Notes

Hand files require no power source, but always inspect the tang before use and fit an appropriate handle to prevent injury. Wear eye protection when filing metal to guard against swarf. Use smooth, consistent strokes with moderate pressure; lifting on the return stroke extends file life. Keep files dry and stored separately to prevent tooth damage from contact with other tools.
