Swiss-Pattern Round File for Precision Work

The Simonds 84163000 is an eight-inch Swiss-pattern round file designed for enlarging and rounding out holes. Its double-cut faces and edges remove material cleanly on aluminium, brass, bronze, steel and tin. The smooth cut coarseness suits finishing tasks where a controlled surface is required. The rigid, tapered body guides easily into existing bores without wandering.

Smooth Cut Coarseness and 5/16-Inch Diameter

The file’s 5/16-inch diameter and double-cut profile handle light stock removal and final sizing in small-diameter holes. The smooth cut leaves a finer finish than bastard or second cuts, reducing the need for subsequent polishing. It runs out when aggressive material removal is needed or when the workpiece exceeds the file’s diameter and taper reach. The eight-inch length without tang provides adequate stroke length for bench use.

Natural Finish Body Supplied in a Box

The natural-finish steel body resists corrosion during storage and requires only a light wipe before use. Supplied in a protective box, the file stays clean and segregated from other tools in a drawer or chest. The rigid construction prevents flexing during push strokes, maintaining consistent geometry. Buyers needing files for flat surfaces, larger diameters or coarse rapid stock removal should select a different profile.

Questions about this item

Will the 8 in Swiss pattern round file work on the steel and aluminium parts I already have in the workshop?

The file is rated for steel, aluminium, brass, bronze and tin, so it will cut the metals you are already using.

How can I check the smooth double-cut finish is performing correctly once I start using the file?

A clean, consistent surface inside a drilled hole with no torn edges shows the smooth double-cut profile is working as intended.

Does the box contain only the 84163000 file or are handles and protective sleeves included?

The container is a simple box holding the 8 in round file; handles and sleeves are not included and must be purchased separately.
