Slater Tools' has expanded its hexalobular-shaped rotary broaches. The contour of the broach's lobed recesses makes it a desirable form for fasteners, the company says. The six-lobe hexalobular insert is available for all rotary broaching toolholders. Rotary broaching cutters can be used on a lathe, horizontal or vertical mill or screw machine to create hexagon, square and other polygon forms in precision metal products. Common products include multiple aircraft and medical applications, such as bone screws. Broach tools (also known as wobble broach tools) for the hexalobular form can now be ordered from stock, improving production and prototype delivery times.
Rotary broaches can be produced from hardened high speed M2 steel, PM4 or T15 cobalt. Tool life on tough applications may be improved using coatings such as TiN, TiCN and TiAlN, available for all rotary broaches.
