Half-Round File with Tungsten Grit Coating 150 mm — Artu 69412

Half-Round File with Tungsten Grit Coating 150 mm — Artu 69412 is a coated abrasive hand tool designed for shaping, smoothing and deburring a variety of materials. The half-round profile combines a flat and a curved surface, enabling work on both planar areas and concave contours. The tungsten grit coating provides consistent abrasive action for fine material removal and edge finishing in workshop and repair tasks.

Advantages

The tungsten grit coating offers durable, uniform abrasion and reduces clogging compared with uncoated metal files when working with composites, wood or non-ferrous metals. The half-round geometry delivers versatility — use the flat face for straight edges and the rounded face for curved profiles. A 150 mm working length balances accessibility and control for hand operations, allowing precise contouring and finishing.

Suitable for

• Shaping and smoothing metal parts and castings
• Contouring and finishing curved surfaces on wood and composites
• Deburring cut edges and removing small amounts of material
• Repair and maintenance tasks in workshops and garages

Key specifications

• Tool type: half-round hand file with coated abrasive surface
• Coating: tungsten (wolfram) grit for consistent abrasive performance
• Working length: 150 mm
• Profile: combined flat and convex surfaces for versatile shaping
• Application materials: metal, wood, composites and non-ferrous materials

How to use

Hold the file by the handle and apply smooth, controlled strokes in the preferred direction of cut, maintaining even pressure to avoid gouging. Use the flat side for straight runs and the curved side for internal radii or rounded edges. Periodically check the surface being worked and remove debris from the coated surface as needed to maintain consistent abrasion. When greater material removal is required, combine coarse passes with lighter finishing strokes to achieve the desired contour and edge quality.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses and gloves. Avoid excessive force that can damage the coating or the workpiece. Store the file in a dry place away from impact to preserve the coating and profile. For best results, pair with a vise or clamping device to secure small workpieces and maintain stable, repeatable strokes.
