Round File
Product Code : LSK-SWES-10710
Round File (SKU LSK-SWES-10710) is a hand file of circular section used to enlarge and true up holes, file concave curves and radius the inside corners of slots. In welding and fabrication training it is the tool for deburring the bore of cut pipe and tube before fit-up. Science Lab Supplies supplies it from Ambala, India, in the sizes and grades listed below, to ITI workshops, polytechnics, colleges, tender contractors and distributors.
Specifications
The file is made in three grades — rough (bastard), medium and smooth — and in lengths of 4 in to 14 in, so small bores and larger pipe ends can both be worked. Its listed features are dimensional accuracy and corrosion resistance.

Applications and Experiments for the Round File
Trainees use the round file for any curved internal surface: opening a drilled hole to size, blending a slot end, filing a concave profile or cleaning burrs from inside a pipe after sawing. It complements the flat file in the filing exercises of fitting, welding and sheet-metal courses.
- ITI Fitter trade: enlarging and finishing drilled holes on fitting jobs.
- ITI Welder and pipe-fitting practice: deburring pipe bores before joint preparation.
- Sheet-metal work: filing internal radii and slot ends.
Standard Scope of Supply
The Round File is supplied as a single unit in the length and grade you choose. Several lengths and grades can be combined on one order so that every bench has a coarse and a fine file; any optional accessories are listed on the quotation.
Packing, MOQ and Lead Time
A quotation can cover a single file or complete sets for a training workshop. It states the packing, delivery time and price for exactly that quantity, and matching flat and triangular files or other bench tools can be priced on the same document, so the whole set is ordered at once.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Enquire via the contact page or enquiry cart; see also the lab tender page.
Frequently Asked Questions
What is a round file used for?
It is used to enlarge holes, file concave curves and remove burrs from the inside of pipe and tube. Its round section reaches surfaces a flat file cannot.
Which grade should a training workshop order?
Most workshops order the rough (bastard) grade for fast stock removal and the smooth grade for finishing, with the medium grade between them for general work.
Who supplies the Round File?
Science Lab Supplies supplies it from Ambala, India as part of its welding and fitting tool range for vocational training centres, colleges and contractors.
Can different lengths be ordered together?
Yes. Any mix of the 4 in to 14 in lengths and the three grades can be quoted together, with each size shown as its own line.
