Applications and Experiments for the Flat File
A flat file is used for filing practice on flat and square surfaces, for deburring sheared or sawn edges and for preparing and dressing welded joints. It belongs in the basic fitting exercises that open welding, fitter and sheet-metal courses, as well as in general engineering workshop practice.
- ITI Fitter and Welder trades: filing a test piece flat and square to a try square, then checking size with a Vernier Caliper.
- Weld preparation: cleaning plate edges and bevels before tack welding on the Shielded Metal ARC Welding Machine.
- Post-weld finishing: removing spatter and dressing bead edges, wearing Grinding Goggles.
- Diploma and B.Tech workshop practice: bench fitting and deburring jobs.
The normal filing sequence is to rough down with the bastard cut, change to the second cut and finish with the smooth file. A handle should always be fitted on the tang before use.

Frequently Asked Questions
What is the difference between bastard, second cut and smooth files?
The bastard cut has the coarsest teeth and removes metal fastest; the second cut is medium; the smooth cut has the finest teeth and gives the final finish. All three grades can be quoted together.
Which lengths are available?
The file comes in 4, 6, 8, 10, 12 and 14 in lengths. Longer files suit heavier stock removal on plate, while short files are easier for trainees working on small parts.
Who supplies the Flat File?
Science Lab Supplies supplies it from Ambala, India, together with the rest of its welding and fitting hand tools, to training institutes, colleges, contractors and distributors.
Can the files be quoted for a tender or a full workshop?
Yes. Send the lengths, grades and number of sets with your delivery location, and the quotation will list each size as a separate line, so it can be checked against your tender schedule.
