Simonds

Simonds 73431000 8 in Square File Smooth Double Cut tool storage

SKU CH-G45N-FXCDY

Square machinist's file with smooth double-cut teeth for aluminium, brass, bronze, steel and tin

  • Smooth double-cut finish removes material cleanly on aluminum, brass, bronze, steel and tin
  • 8 inch square profile reaches tight corners and keyways with four cutting edges
  • Wavy tooth pattern reduces clogging and improves chip clearance during use
  • Safe edges protect adjacent surfaces while filing slots and grooves
  • Rigid construction with natural finish resists corrosion and maintains shape over time

Square machinists file for metalwork

This 8 in square file is designed for machinists and metalworkers who need to deburr, shape or finish flat and internal surfaces on aluminium, brass, bronze, steel and tin. The double-cut pattern with wavy teeth removes material quickly while leaving a smooth surface. Its rigid, tapered profile reaches into corners and keyways where broader tools cannot fit.

Low-effort cutting with controlled pressure

The safe edges prevent unwanted scoring on adjacent faces during side filing. A rigid body transfers hand pressure directly to the workpiece without flex, reducing fatigue during extended bench work. Natural finish on the steel body resists corrosion in workshop environments. No power or lubrication is required for normal use.

Double-cut, 37 to 41 teeth per inch

This tooth density defines the smooth cut rating and determines stock removal rate versus finish quality. Finer work demands a higher count; heavier stock removal needs a coarser file. Choose this specification when the job calls for a smooth finish on the listed metals with an American-pattern square profile.

Questions about this item

How do I mount the Simonds 73431000 8 in square file in a handle, and what step is often missed?

Insert the tapered tang fully into a matching handle ferrule until it seats firmly; the step often missed is checking that the tang is straight and the handle is tight so the file cannot rotate under pressure.

What maintenance will this 8 in smooth double-cut square file need over time?

Clean the 37 to 41 teeth per inch with a file card after each use to prevent metal buildup; the natural finish body requires no oil, but store it dry in its box to avoid surface rust on the 5/16 in faces.

What limit appears first when using this rigid square file continuously on steel?

The smooth double-cut edges dull before the rigid body flexes; once the wavy teeth lose their bite on aluminum, brass, bronze, steel or tin, the file must be replaced because the 8 in cutting length cannot be resharpened.
