Why this one
Half-round profile for versatile access
The curved face lets you file concave surfaces, inside radii, and slots while the flat face handles straight edges and outside contours.
Compact 160 mm (approximately 6.3 in) overall length
Sized to maneuver in spaces where full-length hand files cannot reach, this tool is practical for deburring ports, cleaning keyways, adjusting contact points, and refining surfaces on intricate assemblies.
Double-ended design maximizes usable surface
Both ends of the working area are shaped for filing, so you get more cutting length per tool.
Built for jewelers, machinists, and mechanics
Whether you are shaping precious metal in a jewelry shop, fitting pins and bushings at the machine tool, or trimming a gasket surface under the hood, the half-round cross section reaches into tight radii and blended contours that broader tools simply cannot address.
Individual tool, not a set
Purchase exactly the profile you need without paying for shapes that stay in the drawer.
Read the full description
When detail work demands a filing profile that can handle both curved and flat surfaces in a single stroke, this half-round tool delivers. The curved side follows concave contours, inside radii, and channel walls, while the flat side addresses straight edges, outside surfaces, and shallow chamfers. That dual geometry lets you switch between surface types without reaching for a second tool.
At 160 mm (approximately 6.3 in) in overall length and weighing just 15 g, the compact form factor slides into confined areas where standard-length files would bind or lever against adjacent surfaces. Jewelers shaping bezels, machinists deburring cross-holes, and mechanics cleaning mating surfaces all benefit from the maneuverability a shorter, lighter instrument provides.
The double-ended layout gives you more usable cutting surface per tool. When one working area loads with swarf or begins to dull, shift to the opposite end and continue without interruption. That simple advantage adds up across a full day of bench work.
Sold individually so you buy only the profile your job requires. If your existing kit is missing a half-round or the one you have is past its useful life, this single-profile purchase fills the gap without forcing you into a multi-piece bundle. Add it to your tool roll and keep moving.
