File for Metal GEKO G40078 — square rasp 200 mm, coarse 10/100

GEKO G40078 is a square metal file with a 200 mm blade and a coarse 10/100 cut designed for rapid material removal on ferrous and non-ferrous metals. The square profile allows precise work on flat surfaces, edges and internal corners while the coarse rasp tooth pattern accelerates shaping and deburring tasks in workshop and maintenance environments. The tool is intended to be used with a compatible handle and offers a balance between aggressive cutting and controllable finish.

Advantages

The square rasp shape provides stable contact for filing flats and internal angles, reducing chatter and improving control. Its 200 mm blade length gives reach and leverage for trimming and shaping larger parts. The coarse 10/100 cut removes material quickly, shortening job time when rough stock removal is required. Manufactured to GEKO brand standards, the file combines straightforward geometry with a durable tooth pattern suitable for everyday metalworking tasks.

Suitable for

• Shaping and trimming ferrous metals such as steel and iron
• Removing material from non-ferrous metals like aluminium and brass
• Deburring edges after cutting or stamping
• Filing internal corners and square recesses
• Workshop maintenance and general metal fabrication

Key specifications

• Profile: square
• Blade length: 200 mm
• Cut: coarse (10/100)
• Primary material application: ferrous and non-ferrous metals
• Tooth pattern: rasp-style coarse teeth for fast stock removal

How to use

Secure the workpiece in a vise or suitable clamp to prevent movement. Fit the file into a compatible handle for comfortable two-handed control. Apply steady forward strokes along the length of the blade while keeping the file flat against the surface for even material removal; lift on the return stroke if using single-direction filing technique. For internal corners, orient the square profile so the appropriate edges engage the recess and work progressively to avoid gouging. Periodically clear accumulated filings from the tooth gullets with a file card or wire brush to maintain cutting efficiency.

Usage recommendations

Use the coarse 10/100 rasp for rapid shaping and heavy stock removal; switch to a medium or fine-file for finishing and achieving tighter surface tolerances. Wear appropriate personal protective equipment such as safety glasses and gloves, and keep the file clean and dry to prevent corrosion and preserve tooth sharpness.
