The Professional Gunsmith Needle File Set (21421410) is a must-have precision hand tool kit for anyone who works on firearms, small parts, or intricate metal components. Whether you’re a full-time gunsmith, hobbyist, armorer, or precision tool enthusiast, this compact set of fine needle files delivers the control, feel, and accuracy you need for detailed fitting, deburring, and contouring on steel, aluminum, brass, and other common gun and workshop materials.
Precision Needle Files Designed for Gunsmithing
This professional gunsmith needle file set 21421410 is engineered specifically for the kind of fine work firearm projects demand:
Fitting and blending safety levers, slides, triggers, sears, and small frame parts
Cleaning up milled edges, dovetails, and sight cuts
Removing burrs after drilling, cutting, or stoning
Fine-tuning custom parts where a full-size file is too aggressive
Each needle file is carefully shaped and sized to let you get into tight spots on frames, receivers, and small components without removing too much material at once.
Multiple File Profiles for Versatile Detail Work
Instead of forcing one file to do every job, this gunsmithing needle file set provides a range of profiles ideal for different tasks, such as:
Flat and flat tapered files – for squaring shoulders, flats, and small fitting surfaces
Round and half-round files – perfect for radiused cuts, pin holes, and curved recesses
Triangle (three-square) files – for cleaning corners, dovetail angles, and notch work
Knife-edge or warding-style profiles – for extremely fine slots and tight spaces
With this variety of shapes in the PROFESSIONAL GUNSMITH NEEDLE FILE SET 21421410, you can choose exactly the file you need for the surface you’re working on, improving both quality and consistency.
Fine-Cut Teeth for Controlled Metal Removal
Unlike coarse shop files that remove material aggressively, the needles in this set feature a fine, uniform tooth pattern that’s ideal for precision work:
Controlled stock removal – take off just a little at a time to avoid overshooting dimensions
Smooth, even cutting action – reduces chatter and gouging on critical surfaces
Excellent for final fitting, deburring, and refining areas that have already been machined or stoned
This fine-cut design makes the set particularly well suited to firearm fitting and tuning, where careful, incremental adjustments are essential.
Hardened Steel Construction for Durability
The Professional Gunsmith Needle File Set 21421410 is designed to stand up to real shop use:
Files are made from hardened tool steel for long-lasting performance
Resistant to premature dulling under normal filing pressure
Suitable for use on common firearm steels and alloys, as well as non-ferrous metals and plastics
With proper care and light cleaning, this set becomes a long-term addition to your bench rather than a disposable accessory.
Comfortable Handles for Better Control
Good gunsmithing is all about control, and this needle file set is designed to feel secure in the hand:
Slim, comfortable handles (integrated or supplied) give you excellent tactile feedback
Compact overall length lets you work up close to the part for maximum precision
Ideal for bench vise work, detail fitting, and in-hand touchups
A comfortable, stable grip helps you make tiny corrections instead of big mistakes—especially on expensive firearm components.
Essential Tool for the Gunsmith’s Bench
The PROFESSIONAL GUNSMITH NEEDLE FILE SET 21421410 is ideal for:
Professional gunsmiths who need reliable, fine-detail tools every day
DIY firearm hobbyists doing trigger jobs, sight fitting, and custom part fitting
Armorers maintaining agency or department firearms
Machinists and toolmakers who require fine profiling tools for small parts
Keep it in your main gunsmith tool drawer, or pair it with your punches, stones, and gauge sets as part of a complete firearm setup station.
Great Addition to Any AR, 1911, or Custom Build Toolkit
No matter what you build or maintain—AR-15s, 1911s, bolt guns, revolvers, or custom target pistols—a quality needle file set is one of the most frequently reached-for precision tools. Use this set to:
Break sharp edges on rails and internal parts
Tune and clean dovetails for sights and mounts
Refine mating surfaces for smoother cycling and lockup
Clean up tool marks left by mills, drills, or rotary bits
The Professional Gunsmith Needle File Set 21421410 gives you the control needed to make a good fit into a perfect fit.
