Triangular machinists file
The Simonds 73516500 is a 6-inch American-pattern machinists file with a triangular profile. It is designed for metalworkers and tradespeople shaping aluminium, brass, bronze, steel or tin. The rigid body tapers toward the point for access into corners and tight angles.
Wavy tooth design and cut pattern
An exclusive wavy tooth design combines a double-cut face with single-cut edges across three cutting surfaces. Coarseness is rated bastard cut with teeth-per-inch values of 28, 34 and 40 distributed across the faces. The pattern removes material efficiently while leaving a finish suited to further hand finishing.
Natural finish and boxed supply
The file body carries a natural finish without coating, preserving the steel surface for consistent cutting feel. It ships in a protective box that keeps the teeth from damage during storage or transport. The 7/16-inch thickness gives a substantial grip without needing a separate handle.

Questions about this item
How often will the 6 in triangular file need replacement when used on steel?
The file has an exclusive wavy tooth design with 28, 34 and 40 teeth per inch across its three faces; lifespan depends on material hardness and pressure applied.
What limits continuous filing sessions with this 7/16 in thick tool?
The rigid triangular profile tapers toward the point and is made for hand filing; operator fatigue and heat buildup in the workpiece are the practical limits.
Does the natural-finish file generate noticeable heat or noise during all-day use?
Hand filing produces minimal noise; heat stays low because only three cutting edges engage at once, and the single-cut edges reduce friction.
