CUSTOM HEX BROACHES

Rayco manufactures standard and custom hex broaches for rotary (wobble) and push broaching applications. Full-form, 2-point and 3-point hex broaches are available for standard and custom sizes. Rayco #7 broaches are engineered for demanding materials including Inconel 718, titanium, Cobalt Chrome, 17-4 H900, Custom 455 and other hard alloys.

FULL FORM HEX

Full-form hex broaches cut the complete hex shape in a single broaching cycle and are available for rotary/wobble or push broaching. They provide the fastest method of producing an internal hex when machine thrust and application conditions allow.

2 POINT HEX BROACH

A 2-point hex broach reduces cutting load by forming two corners at a time. The part is indexed between passes until the complete hex is produced. This design can be useful where lower broaching force is required, although deeper forms may be more sensitive to deflection.

CUSTOM HEX BROACH CONFIGURATIONS

Rayco can recommend full-form, 2-point, 3-point and other custom broach geometries based on form size, depth, workpiece material, hardness, machine capability and production requirements. Application support and onsite setup assistance are available when needed.

RAYCO #7 — Rayco’s special-purpose heat-treated HSS for difficult alloys and high-hardness applications. Rayco #7 has been successfully used in applications up to 55 HRC, including Cobalt Chrome, Custom 455, BioDur 108, 17-4 H900, strain-hardened 316, titanium, Inconel 718, Monel and hardened aerospace alloys. It is intended for applications where conventional broach tool life is inadequate.
