250 mm Round Hand File With Bi-Material Ergonomic Handle

When a job calls for smoothing a curved internal surface, enlarging a drilled hole, or cleaning up the inside of a tube, a round profile is the only geometry that follows the workpiece. This 250 mm Teng Tools file delivers exactly that capability in a size suited to real machinist tools and fabrication tasks rather than miniature hobby work.

The bi-material handle combines a firm core with a softer outer layer, giving you a secure grip and reduced vibration. It is permanently attached, so there is no loose wooden handle to split or spin. The red and black ergonomic shape fits the hand naturally and helps you maintain a consistent stroke pressure.

At 190 g (approximately 6.7 oz) and 250 mm (approximately 9.8 inches) in length, this file is light enough for detailed work yet long enough to produce efficient, full-length strokes. The tapered round cross-section lets you start in a smaller opening and work progressively outward, matching the radius of the cut to the task.

Whether you are fitting bushings, blending weld joints inside pipe, or simply knocking down a sharp edge on a freshly drilled hole, this individual file belongs in every working tradesman's tool collection. Pair it with flat and half-round profiles from the same Teng Tools range for complete coverage of every filing geometry you encounter.
