Wittmann Werkzeuge broaching tools and precision tooling

Supplying high-precision broaches, replaceable tooling inserts and rotary broaching equipment from Wittmann Werkzeuge GmbH for CNC machining centers and fastener manufacturing plants worldwide.

Hexagon socket broaches

Wittmann hexagon socket broaches are precision ground from high-speed steel grade HSS 1.3343 hardened to 64 ± 2 HRC in standard dimensions 12x55, 8x28, 5x20 and 5x17 mm. Calibrated cutting edges ensure clean internal profile broaching. Replaceable inserts are available uncoated or with TiN coating.

Engineering design and material specifications

Wittmann Werkzeuge GmbH manufactures high-precision broaching tools engineered for rapid internal profile generation on CNC turning and machining centers.

The choice of premium HSS 1.3343 high-speed tool steel hardened to 64 ± 2 HRC ensures exceptional edge stability during mass production of alloy components.

Standard shank dimensions including 12x55 and 8x28 mm guarantee rigid tool location within rotary broaching holders and industrial tool adaptors.

Rotary broaching kinematics on CNC machine tools

Rotary wobble broaching technology enables the machining of internal hexagons and Torx profiles in a single pass without dedicated broaching equipment. The broaching holder inclines the tool axis by one degree relative to the workpiece axis.

This creates a rotating point contact that shears metal incrementally while drastically minimizing axial feed thrust compared to conventional push broaching.

Pre-drilled pilot hole preparation parameters

Clean profile generation without tool deflection requires accurate pilot hole preparation in the blank workpiece. The pre-drill diameter should exceed the nominal inscribed circle diameter by 0.1 to 0.15 mm, combined with an entry lead-in chamfer of 45 degrees.

Hole depth must incorporate adequate chip clearance space at the bottom to prevent axial compression and tool fracture.

Tool life extension via advanced PVD coatings

Application of titanium nitride TiN and titanium aluminum nitride TiAlN coatings through physical vapor deposition substantially enhances cutting edge surface hardness and wear resistance.

The thin protective ceramic layer lowers friction coefficients, minimizes chip adhesion on tool cutting edges, and substantially prolongs tool life when cutting high-tensile steels and titanium alloys.

Toolholder interface and system compatibility

Wittmann broach tools are precision manufactured to match rotary broaching holders from systems PCM, Zürn, and Arno.

Tight h6 ground tolerance on the mounting shank ensures optimal radial concentricity with the drive spindle, minimizing runout errors and ensuring high repeatability during automated tool changes on multi-axis turning machines.

Profile inspection and quality verification standards

Internal sockets and splines formed by Wittmann broaches meet strict dimensional standards including DIN ISO 10664, DIN 912, and automotive specification VW-Norm 01043.

Precision profile grinding eliminates taper and burrs, providing dependable component fit in precision machinery and automotive drive assemblies.
