Flat File
Product Code : LSK-SWES-10708
Flat File (SKU LSK-SWES-10708) is a hand-cut steel file with a flat, rectangular section, used to remove metal, square edges and smooth surfaces by hand. It is a standard bench tool for welding, fitting and fabrication trainees, who use it to dress weld beads, deburr cut plate and finish joints before inspection. Science Lab Supplies supplies it from Ambala, India to ITI and polytechnic workshops, TVET centres, engineering colleges, tender contractors and distributors, as one of the ITI trade tools in its welding range.
Specifications
The file is offered in three grades of cut — rough (bastard), medium (second cut) and smooth — and in six lengths from 4 in to 14 in. The listed features are corrosion resistance and low maintenance, so the file suits workshops where tools are shared between batches of trainees.

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.
- Weld preparation: cleaning plate edges and bevels before tack welding.
- Post-weld finishing: removing spatter and dressing bead edges on practice coupons.
- Diploma and B.Tech workshop practice: bench fitting and deburring jobs.
Trainees usually rough down with the bastard cut, then change to the second cut and finish with the smooth file. A handle should always be fitted on the tang before use.
Standard Scope of Supply
The Flat File is supplied as a single unit as described above, in the length and grade of cut you specify. Mixed lengths and grades can be combined on one order for a workshop set, and any optional accessories are listed on the quotation.

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. Workshops often buy all three.
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.
Related Hand Tools for Welding and Fitting
These four items sit next to the flat file on a welding and fitting bench: two other file sections for curved and angled work, a hacksaw for cutting stock to size, and a powered grinder for heavier weld dressing. Together they cover the cutting and finishing steps of most practice jobs.
- Round File — for enlarging holes and filing curved profiles.
- Triangular File — for corners, internal angles and thread repair.
- Hacksaw Frame — cuts bar and plate before filing.
- Angle Grinder — powered grinding of weld beads and bevels.
