Work inside holes, pipe openings, and curved recesses with the Benchmark Abrasives 8" Round File (Bastard Cut). Its round profile helps you enlarge openings, remove burrs, and refine internal contours by hand. The bastard-cut grade provides relatively coarse cutting action for efficient stock removal, while the longer 8" size offers added reach and filing surface for larger workpieces and general maintenance applications.

Product Features
Round profile is suited for circular openings, pipe interiors, and concave surfaces.
Bastard-cut grade provides coarse cutting action for efficient material removal.
Useful for enlarging holes and refining internal contours.
8" nominal length provides additional reach and filing surface compared with shorter files.
Suitable for fitting, shaping, deburring, and general maintenance work.
Designed for manual hand filing.
Applications & Performance
The 8" Round File is intended primarily for circular openings, pipe interiors, and concave work. Its round profile allows controlled material removal in areas where flat-profile files are not well suited.
Common applications include:
Enlarging circular openings
Filing inside pipe and tubing
Shaping concave surfaces
Radius and contour work
Deburring internal edges
Fitting and adjustment
General maintenance and repair work
For ordinary filing, apply controlled pressure on the forward stroke and reduce pressure during the return stroke.
Safety Tips
Secure the workpiece on a bench or in a vise instead of holding it in the palm of your hand.
Wear appropriate eye protection and other PPE required for the material and task.
Use a securely fitted handle on a tanged file. Inspect the file and handle before use, and replace damaged handles.
Never strike a file or use it as a pry bar, hammer, punch, or other impact tool.
Keep the teeth clean and remove trapped chips or pinning as needed.

Frequently Asked Questions
An 8" round file is designed primarily for holes, pipe interiors, concave surfaces, and other internal curves. It can be used to enlarge openings, refine radiused features, and remove material from curved internal surfaces.
Bastard cut refers to a relatively coarse file grade intended for efficient stock removal. It is coarser than second cut.
No. The round profile is primarily intended for circular and concave work. A flat or half-round file is generally better suited when the primary work surface is flat.
This is a general-purpose round file for holes and inside curves. For chainsaw cutters, choose a dedicated sharpening file matched to the chain manufacturer’s specified size and shape.
No. This is a hand file for manual use. It is not designed to mount in an air saw or powered filing tool.
Apply controlled cutting pressure on the forward stroke and reduce pressure on the return stroke. This helps maintain effective cutting action while limiting unnecessary wear.
Metal chips trapped between the teeth are commonly called pinning. Remove embedded chips periodically to help maintain cutting performance.
Choose the 8" size for everyday filing when you want a balance of control and reach. Match the file profile to the surface you need to work on.
