Simonds 73321500 Half Round File 10in Second Cut

SKU CH-85E8-RCR99

Half-round machinist file, 10 in long, second-cut double-cut teeth for aluminium, brass, bronze, steel and tin

  • Second-cut teeth leave a smooth finish on steel and brass
  • Half-round profile reaches flat surfaces and inside curves alike
  • Safe edges protect adjacent faces while you file
  • Double-cut faces on both sides remove material quickly
  • 10-inch length gives leverage without sacrificing control

Half-Round File for Machinists

The Simonds 73321500 is a 10 in American pattern machinists file with a half-round profile. Its double-cut faces and safe edges suit shaping aluminium, brass, bronze, steel and tin in workshop and garage tasks.

Rigid Steel Construction

The rigid file body has a natural finish and measures 15/16 in wide by 9/32 in thick. Second-cut coarseness delivers 25 to 31 teeth per inch across two cutting edges for controlled material removal without clogging.

Boxed for Storage

The file ships in a protective box that keeps the cutting surfaces clean and prevents damage during transport. No additional handles, cards or lubricants are included with the single-unit package.

Questions about this item

How do I install the 10 in half-round file in my tool storage and what step is often missed?

Place the file in a slotted tray or rack with the tang facing outward; the step often missed is leaving enough clearance so the 15/16 in wide body does not bind against adjacent tools.

What maintenance or replacement will the 73321500 file need later?

Clean the double-cut teeth with a file card after each use and apply a light oil film to the natural-finish body; replace the file once the 25–31 teeth per inch no longer remove material cleanly.

What limit appears first during sustained filing with the second-cut half-round file?

The safe edge stops cutting into shoulders first, so the 9/32 in thick profile loses its corner-holding ability before the rigid body shows any wear.
