Half-round metal file NEO tools 200 x 2 mm model 37-122

Half-round metal file NEO tools 200 x 2 mm model 37-122 is a hand tool designed for shaping, smoothing and deburring metal surfaces where both flat and curved filing are needed. The half-round profile provides a convex and a flat face in a single tool, allowing transitions between concave and planar contours without changing tools. This file is intended for use in workshops, repair tasks and hobby metalworking where precise material removal and surface finishing are required.

Advantages

The half-round shape combines two working faces — a curved side for radii and concave profiles and a flat side for straight edges and flat surfaces — reducing the need to switch tools. With a narrow 2 mm thickness and 200 mm length, the file offers controlled access to tight spaces and fine detail work. The hardened and tempered steel cutting surface maintains consistent cutting action and resistance to wear under normal hand-tool conditions.

Suitable for

• Shaping and smoothing metal edges and contours
• Deburring holes, grooves and weld seams
• Fitting and finishing curved surfaces such as fillets and radii
• Small repairs and detail work in workshops and hobby projects
• Preparing mating surfaces before assembly or welding

Key specifications

• Overall length: 200 mm
• Working thickness: 2 mm
• Profile: half-round (one convex and one flat face)
• Material: hardened and tempered steel working surface
• Intended use: manual metal filing for shaping, smoothing and deburring

How to use

Secure the workpiece firmly in a vise or clamped support before filing. Hold the file by the handle with one hand and guide the tip with the other for precision. Apply smooth, even forward strokes along the workpiece using the curved face for concave shapes and the flat face for planar areas. Do not use excessive downward force; let the file’s teeth cut the material. Clean filings from the teeth regularly with a file card to maintain cutting efficiency and avoid clogging.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For best results, pair the file with a suitable handle to improve grip and control. Store the file in a dry place to prevent corrosion and avoid contact with other tools to protect the cutting surface.
