Rotary Broaching Tools
Precision rotary broaching tools for Swiss-type lathes and CNC lathes, designed for producing hexagonal, Torx, square and custom internal profiles.
How Rotary Broaching Works
How does rotary broaching work?
Rotary broaching uses a broach held at a slight angle to the workpiece centerline. This creates a controlled wobbling action, allowing the cutting edges to progressively form the internal profile as the tool feeds into the workpiece.

Special & Custom Rotary Broaches
Custom Profiles
Made to order according to customer drawings or specifications. Custom internal profiles can be manufactured according to the required geometry, dimensions and machining application.
Material & Technical Information
PRONIXT rotary broaching tools for Swiss-type lathes and CNC lathes are designed for precision machining of hexagonal, Torx, square and custom internal profiles. Standard broaches are manufactured from ASP23 powder metallurgy high-speed steel for a balanced combination of wear resistance, toughness and stable cutting performance.
ASP23 Powder Metallurgy High-Speed Steel
ASP23 PM-HSS is selected for PRONIXT rotary broaches because the powder metallurgy structure provides a fine and uniform microstructure with a strong balance of wear resistance and toughness. This makes the material well suited to precision rotary broaching applications where the cutting edges are subjected to repeated cutting loads during the rotary broaching process.
Applicable Work Materials
Typical applications include D2, H13 and SKD11 tool steels, 304 / 316 / 420 / 440 stainless steels, and Ti-6Al-4V Grade 5 titanium alloy. Hardened steel applications up to approximately HRC 60–62 are subject to profile size, broaching depth and actual machining conditions.
Tolerance & Precision
Coating Options
TiCN — Standard Stock Coating
Blackish PVD finish selected for standard PRONIXT
rotary broaches, providing additional wear protection
for precision cutting applications.
TiN — Custom Coating Option
Gold PVD finish available upon request for applications
requiring an alternative surface coating.
Coating selection can also be evaluated according to the workpiece material, profile geometry and machining conditions.
