Files

Files are hand tools and replacement blades used to shape, smooth, deburr, refine, and sharpen material surfaces. Common commercial uses include maintenance, fabrication, metalworking, tool sharpening, saw maintenance, fitting work, and surface shaping on materials such as metal, wood, plastic, fiberglass, soft metals, vehicle filler, and boat filler.

Helpful Buying Guide

Choose the right file for the surface and task

File selection starts with the workpiece shape, the amount of material to remove, and whether you need a complete hand file or a replacement blade for a compatible tool. Compare profiles, cuts, lengths, edge designs, and handle arrangements to match the file to the task.

Use Cases

Match the file to the job

Use flat files for broad surfaces and edges, square files for angles and inner corners, and round or half-round profiles for holes, concave areas, curves, and contoured surfaces. Saw files are made for sharpening saw teeth, while rasp files support shaping and smoothing wood, plastic, soft metals, and similar materials.

How to Choose

Compare profile, cut, and format

Choose the profile based on the surface shape, then compare the cut for the desired material removal. Standard, smooth, second, bastard, and coarse cuts are represented. Also confirm whether you need an unhanded file, a file with a handle, or a replacement blade for a compatible tool.

Applications

Support maintenance and finishing work

These files are suited to shaping edges, removing burrs, refining flat surfaces, working corners and shoulders, smoothing curved areas, sharpening implements, and maintaining saw teeth. Some replacement blades are intended for continued use of compatible shaping tools.

Additional Info

Check access and control features

Tapered tips can help reach tighter areas, while flush edge teeth can help work into edges. Uncut edges allow controlled filing near adjacent surfaces. For replacement blades, verify the blade length, profile, cut, and listed tool compatibility where provided.

Comparison Guide

Compare file types by working profile

Use the file profile and construction details to narrow options for your material and surface geometry.

File typeBest suited tasksKey selection details
Flat file or flat bladeFlat surfaces, edges, corners, shoulders, and shaped edgesAvailable with smooth or standard cut; one flat blade includes flush edge teeth, and one flat file has a tapered pointed tip.
Square, round, or half-round fileAngles and inner corners; holes and curved surfaces; flat, concave, and contoured areasSquare files support inner-corner work; round blades work within holes; half-round profiles address curved and concave surfaces.
Specialty file or raspSaw sharpening, material fitting, and shaping wood, plastic, soft metals, and similar materialsTriangular taper saw files are for saw teeth; rasp files have a rasping surface for material removal during fitting and finishing.
Planning Guide

Plan the right fit before choosing

Select a profile

Let the workpiece shape guide your choice

The file profile determines where and how the tool can contact the workpiece. Flat formats provide a broad surface for flat-area and edge work, while shaped profiles help address openings, contours, and corners.

  • Flat files and blades suit flat surfaces, edges, corners, shoulders, and shaped edges.
  • Square files help with angles, inner corners, holes, large fillets, and concave surfaces.
  • Round blades help enlarge holes and refine curved surfaces.
  • Half-round files and blades work on curved, contoured, flat, concave, and large-hole areas.
  • Triangular taper saw files are designed to access and shape individual saw teeth.
Choose the cut

Balance controlled finishing with material removal

The represented file cuts support different types of filing work. Select the cut based on whether the task calls for controlled refinement, general shaping, sharpening, or more aggressive removal.

  • Smooth-cut files support controlled filing, deburring, finishing, and edge refinement.
  • Standard-cut files and blades support everyday shaping, smoothing, and consistent material removal.
  • Bastard-cut files support sharpening, general surface refinement, shaping, and deburring.
  • Coarse-cut replacement blades support more aggressive material removal than a fine-cut blade.
  • Second-cut teeth support controlled saw-sharpening work.
Confirm the tool format

Decide between a hand file and a replacement blade

Some options are complete hand tools, while others are replacement blades intended to restore compatible tools. Handle configuration also varies across the selection.

  • Unhanded files allow users to select a compatible or preferred handle separately.
  • A two-component handle provides a comfortable grip for hand-guided work.
  • A high-impact ABS handle and ribbed front section support grip and two-hand control on the rasp file.
  • Replacement blades are available in flat, round, and half-round profiles.
  • One half-round replacement blade is listed as compatible with tool models 21-295 and 21-296.
FAQ

Common questions before buying

What file profile should I use for curved surfaces?

Round and half-round profiles are represented for curved work. Round blades help work within holes and along curved surfaces, while half-round options support curved, contoured, concave, and large-hole areas.

Which files can be used for deburring?

Smooth-cut square and flat files support controlled deburring and edge refinement. Bastard-cut mill and half-round files also support deburring during shaping and surface-refinement work.

Are handles included with every file?

No. Several files are unhanded, allowing a handle to be selected separately. Other options include a two-component handle or an ABS handle.

How do I select a replacement blade?

Match the blade profile, cut, and length to the existing tool and application. Where compatibility is listed, verify the tool model before choosing a replacement blade.
