Frequently asked questions
Common questions about KNIFE from 3G Electric.
What is the difference between the KNIFE double-cut knife files with bastard, second, and smooth cuts?
The cut type refers to the coarseness of the file teeth. Bastard cut is the coarsest among the three, removing material quickly and leaving a rougher finish. Second cut is finer, providing a smoother finish with moderate material removal. Smooth cut is the finest, used for finishing and polishing. In the KNIFE line, models like 12F810 and 12F809 are bastard cut, 12F818 and 12F817 are second cut, and 12F823, 12F861, and 12F860 are smooth cut. Selection depends on the desired surface finish and stock removal rate.
What are the available sizes for KNIFE double-cut knife files?
KNIFE double-cut knife files are available in lengths without tang of 4, 6, 8, 10, and 12 inches. Widths range from 1/2 inch to 1 1/4 inches. For example, model 12F814 is 4 inches long and 1/2 inch wide, while 12F818 is 12 inches long and 1 1/4 inches wide. The size selection affects the file's rigidity and the size of the workpiece it can effectively work on. Smaller files are suited for intricate work, while larger files are for broader surfaces.
Can KNIFE double-cut knife files be used on hardened steel?
Knife files are typically made from high-carbon steel and are hardened to a certain degree, but they are not designed for filing hardened steel. They are intended for use on softer metals, such as mild steel, aluminum, brass, and plastics. Attempting to file hardened steel can dull the teeth rapidly and damage the file. For hardened materials, other tools like diamond files or grinding wheels are recommended. Always check the material compatibility before use.
How should KNIFE double-cut knife files be maintained?
To maintain KNIFE double-cut knife files, keep them clean and dry. After use, remove metal chips with a file card or brush. Avoid getting them wet to prevent rust. Store them in a dry place, preferably in a tool roll or holder to protect the teeth. Do not use them on hardened materials or apply excessive pressure, as this can break teeth. With proper care, they will last for many operations. Replace when the cut becomes inefficient.
What is the typical application for a KNIFE double-cut knife file?
KNIFE double-cut knife files are used for precision filing in narrow slots, keyways, and sharp internal corners. They are common in maintenance shops, tool rooms, and metalworking facilities for deburring, sharpening, and shaping metal edges. The double-cut pattern allows for efficient material removal while providing a relatively smooth finish. They are also used for sharpening saw teeth and other cutting tools. Their tapered shape enables access to confined areas that other files cannot reach.
