Circle Cutters & Diamond Files at True Value
While circle cutters and diamond files are both hole saw accessories, they serve very different purposes. Circle cutters are designed to create adjustable circular holes in sheet materials, while diamond files are used for shaping, sharpening, and smoothing hard materials. The table below outlines the key differences for each tool:
Product Type | Best For | Key Features | Image |
Cutting circular holes in drywall, plywood, MDF, and sheet metal | Adjustable arms (often 7/8”–6”+ options), hardened cutting blades, drill-compatible shank |  | |
Shaping, sharpening, and smoothing glass, ceramic, tile, carbide, and steel | Flat, diamond-coated abrasive surface, fine material removal |  |
Why Use Circle Cutters & Diamond Files?
These tools are designed for precision work, not general cutting. Choosing the right one improves accuracy, reduces waste, and delivers cleaner results.
- Circular Cuts Without Multiple Hole Saws: Circle cutters allow you to adjust diameter rather than buying multiple fixed-size hole saws. This is especially useful for installing recessed lights, ceiling speakers, or vent openings.
- Cleaner Edges, Less Finishing Work: A properly set circle cutter creates smooth edges in drywall or wood, which reduces sanding and patching time. Diamond files refine rough edges after tile or metal cutting.
- Controlled Material Removal: Diamond files remove material gradually rather than aggressively. This prevents cracking brittle materials like glass or ceramic tile and allows for better shaping.
- Versatility: Instead of buying specialty hole sizes or replacing chipped blades, these tools let you make adjustments on the job. Diamond files also restore cutting edges on carbide tools, which extends tool life.
- Increased Accuracy: Circle cutters are adjustable in small increments, allowing you to tailor to the exact diameter you need to cut. Diamond files help refine parts for an exact fit.
Considerations When Purchasing a Circle Cutter
When choosing a circle cutter, a few considerations should be made to ensure your tool meets the needs of your project. Below are some things you should consider before purchasing:
- Diameter Range: Confirm the adjustable range meets your project needs (Do it Best models adjust from 7/8” up to 6”).
- Material Thickness: Best for drywall, MDF, plywood, and other thin sheet goods. Not intended for thick framing lumber.
- Drill Compatibility: Ensure the shank size matches your drill (True Value offers 1/4” options).

While they create accurate circular openings, light sanding may still be needed depending on the material and finish quality required.
Yes, fine-grit diamond files are often used to smooth chipped tile edges after cutting to help create a cleaner finish.
