Machinists File for Metalworking

The Simonds 73518000 is an American pattern machinists file designed for shaping aluminium, brass, bronze, steel and tin. Its triangular profile and rigid construction suit bench work where material removal and edge refinement are required.

Double-Cut Faces with Single-Cut Edges

Each of the three faces carries a double-cut pattern while the edges are single-cut, giving aggressive stock removal on flats and smoother finishing on arrises. The exclusive wavy tooth design reduces clogging, and the file tapers toward the point for access into corners and slots.

22, 26 and 32 Teeth per Inch Bastard Cut

The bastard cut coarseness is graded at 22, 26 and 32 teeth per inch, which defines the aggressiveness and finish quality. Buyers who need a finer smooth cut or a heavier roughing file should select a different coarseness grade.
