File — GEKO triangular metal rasp 200 mm (coarse) model 10/100

GEKO triangular metal rasp 200 mm (coarse) model 10/100 is a hand rasp designed for metalworking tasks that require access to tight corners and internal angles. Its triangular cross-section and 200 mm length make it suitable for shaping, trimming and deburring metal parts where flat or round rasps cannot reach. The coarse tooth pattern provides rapid material removal on steel and other ferrous and non-ferrous metals, enabling efficient profiling and edge work in workshop and maintenance environments.

Advantages

The triangular geometry allows work in internal corners and along profiles that are inaccessible with flat rasps. A coarse rasping pattern (10/100) removes material quickly, reducing working time when rough shaping or heavy deburring is required. The rigid metal body provides stability during use and consistent tooth engagement for predictable cutting action. The 200 mm length balances reach and control for handheld metalworking tasks.

Suitable for

• Deburring sharp edges and removing burrs from machined metal parts
• Shaping and trimming metal profiles in tight corners and internal angles
• Preparing surfaces for welding or fitting by removing excess material
• General workshop maintenance and repair of metal components

Key specifications

• Overall length: 200 mm
• Cross-section shape: triangular
• Tooth pattern: coarse (10/100) for aggressive material removal
• Intended materials: steel and other metals (ferrous and non-ferrous)
• Typical use: shaping, trimming, deburring, profiling in confined spaces

How to use

Hold the rasp with a controlled two-handed grip or secure the workpiece in a vise to ensure stability. Apply even strokes along the workpiece surface, maintaining the rasp at the required angle to reach internal corners and profiles. Use moderate pressure to allow the coarse teeth to cut effectively without clogging; periodically clear accumulated filings from the teeth with a wire brush to maintain cutting performance. For final fitting or fine shaping, follow with finer abrasives or files as needed.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses and gloves. Use the rasp on clean, secured workpieces and avoid excessive bending or twisting to prevent tooth damage. For best results on hardened steels, combine with suitable cutting fluids and finish with finer tools after coarse rasping.
