Forte Rotary Broaches

January 01,2015

Somma Tool Co., a manufacturer of rotary broaching tools and holders, announces a new line of broaches called Forte.

Forte broaches are made of a tough broaching material. It is the company's new standard stock material replacing M2.

Forte has a high wear resistance, resulting in better tool life plus no chipping, according to the company.

The Forte broaches take a deep depth of cut and can be used in non-Somma broach holders as well.

ANSI hex and square broaches are stocked for same day shipping. Special "to print" sizes are available in 1-2 days.

Related Glossary Terms

  • broach


    Tapered tool, with a series of teeth of increasing length, that is pushed or pulled into a workpiece, successively removing small amounts of metal to enlarge a hole, slot or other opening to final size.

  • broaching


    Operation in which a cutter progressively enlarges a slot or hole or shapes a workpiece exterior. Low teeth start the cut, intermediate teeth remove the majority of the material and high teeth finish the task. Broaching can be a one-step operation, as opposed to milling and slotting, which require repeated passes. Typically, however, broaching also involves multiple passes.

  • depth of cut

    depth of cut

    Distance between the bottom of the cut and the uncut surface of the workpiece, measured in a direction at right angles to the machined surface of the workpiece.

  • wear resistance

    wear resistance

    Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
