Lime Bahco 1-143-08-1-2

The BAHCO flat bastard cut file is a hand tool designed for controlled material removal and surface shaping. Weighing approximately 140 g, this flat file features a bastard-cut tooth pattern that balances aggressive stock removal with a reasonably smooth finish. Its robust construction supports repetitive use in both metalworking and woodworking environments, offering consistent performance when deburring, fitting, or refining edges and profiles.

Advantages

The file’s flat profile and bastard cut provide an efficient cutting action across a range of materials, reducing work time while maintaining control. The weight and balance deliver steady hand feel for precise strokes. Durable manufacture helps resist premature wear, ensuring the file retains its cutting geometry through extended use. The tool is suitable for use with a handle or in a pin vise for detailed work, enabling versatility across tasks.

Suitable for

• Deburring and smoothing metal edges
• Shaping and fitting wooden joints and profiles
• Refining machined parts and removing burrs
• General workshop maintenance and tool sharpening prep

Key specifications

• Type: flat file
• Cut: bastard (coarse-to-medium tooth)
• Approximate weight: 140 g
• Application: metalworking and woodworking
• Profile: rectangular/flat cross-section for face and edge work

How to use

Secure the workpiece and use the file with steady, even strokes in the direction of the cut; lift on the return stroke if using a single-cut motion to avoid dulling the teeth. Apply consistent pressure, increasing slightly when removing more material and easing when approaching final dimensions. Use a suitable handle for safer, more controlled operation and keep the file clean of debris by brushing the teeth regularly with a file card.

Recommendations

Store the file dry and protected to prevent damage to the teeth. Match the bastard cut to the material and task: use for general shaping and moderate stock removal, then switch to finer-cut files for finishing. Avoid excessive lateral force that can bend the file or damage the workpiece.
