Enlarge holes and clean up inside curves with the Benchmark Abrasives 6" Round File (Bastard Cut). Its compact round profile reaches concave surfaces where a flat file is not a good fit. The bastard-cut grade provides relatively coarse cutting action for efficient material removal. Its 6" nominal size offers good control for detailed filing, fitting, deburring, and maintenance work where access to curved or enclosed surfaces is important.

Product Features
Round profile is designed for holes, inside curves, and concave surfaces.
Bastard-cut grade provides coarse cutting action for efficient stock removal.
Useful for enlarging and refining circular openings.
Compact 6" size provides control for detailed hand filing.
Suitable for shaping, fitting, deburring, and general maintenance work.
Designed specifically for manual hand filing.
Applications & Performance
The 6" Round File is intended primarily for circular openings and concave work. Its round profile makes it particularly useful where the filing surface curves inward or where material must be removed from the inside of a hole.
Common applications include:
Enlarging circular openings
Filing inside holes
Shaping concave surfaces
Radius and contour work
Deburring internal edges
Fitting and adjustment
General repair and maintenance work
For ordinary filing, apply controlled pressure during 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
A round file is designed primarily for holes, inside curves, and concave surfaces. It is useful for enlarging openings, refining radiused features, and removing material from internal contours.
Bastard cut refers to a relatively coarse file grade intended for efficient material removal. It is coarser than second cut and is well suited for general stock-removal work.
No. The round profile is best suited for circular openings and concave surfaces. A flat or half-round file is generally more appropriate 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 during the return stroke. This helps maintain effective cutting action while limiting unnecessary wear.
Material trapped between the teeth is commonly called pinning. Clean the file periodically and remove embedded chips to help maintain cutting performance.
Choose the 6" size for smaller workpieces and filing jobs where control matters more than reach. Match the file profile to the surface you need to work on.
