Simonds 73228000 Flat File

This Simonds 73228000 flat file is a 4-inch American pattern machinists file with a smooth double-cut face and single-cut edges. It has a rectangular profile that tapers toward the point and a natural finish. The file is designed for material removal on aluminium, brass, bronze, steel and tin.

Suited for precision shaping and finishing

The rigid construction and wavy tooth design suit machinists and metalworkers who need controlled stock removal on non-ferrous and ferrous metals. It is not intended for aggressive hogging on thick sections or for use on hardened tool steels where a coarser bastard or second cut would be required.

Four-inch length with 62 to 70 teeth per inch

The 4-inch cutting length and fine tooth count of 62, 68 and 70 teeth per inch provide smooth finishes on thin-walled workpieces and detail areas. Headroom runs out on wider surfaces where a longer file would maintain flatness, and on heavy material removal tasks where the smooth cut loads quickly.

Questions about this item

Do I need a separate handle for the 4in tang to use this file?

The file tapers toward the point and is designed to accept a standard machinist handle that fits a 4in tang.

Will the double-cut 62-70 TPI teeth work on the brass and aluminum I already shape with single-cut files?

Yes, the smooth double-cut pattern is rated for brass, aluminum, bronze, steel and tin alongside your existing files.

How can I confirm the file is cutting smoothly after I mount the handle?

Run the file across a test piece of steel; the 62-70 teeth-per-inch double cut should leave a uniform, smooth surface without chatter.
