PRECISE BROACHING TOOLS

Internal broaching tools are used to bring pre-drilled holes to precise tolerances (H7, H8) or to cut profiles such as spline, square, and hexagon inside the hole. They provide high surface quality and dimensional accuracy in a single pass.

Technical Types:

• Spline Broach: Straight-sided splines (DIN ISO 14, DIN 5462, DIN 5463).
• Involute Spline Broach: Gear-shaped internal profiles (DIN 5480, DIN 5482, ANSI B92.1).
• Serration Broach: Fine tooth connection profiles (DIN 5481).
• Trapezoidal Broach: For power transmission shafts (DIN 103, ISO 2903).
• Polygon Forms: Square, Hexagon, and Octagon hole broaches.
• Material: HSS (M2) or PM-HSS (ASP2023/2030).

Designed for removing material on external surfaces or cutting single-sided keyways inside holes. Surface broaching is much faster and more economical than milling in mass production.

Applications:

• Keyway Broach: Standard keyway cutting (DIN 6885, JS9, P9 Tolerance).
• Flat Surface Machining: Engine blocks, connecting rods, and reference surfaces.
• Dovetail Broach: Turbine blades and slide systems.
• Fir Tree Broach: Aerospace and energy turbine disks.

Designed and manufactured from scratch according to customer technical drawings or 3D models for non-standard, complex geometry parts.

Sample Projects:

• Firearms Industry: Receiver internal channels (Lower/Upper), mechanism housings.
• Lock Systems: Cylinder lock slots and key channels.
• Automotive: Steering systems and transmission parts.
• Rotor/Stator: Electric motor slot broaches.

Checking the accuracy of broached parts is vital. We manufacture certified gauges for the inspection of the profiles we machine with our broaching tools.

Our Products:

• Spline Gauges: Go / No-Go ring and plug gauges.
• Keyway Gauges: Slot width and depth control.
• Special Profile Gauges: Verification of complex forms.
• All gauges are delivered with an accredited calibration report.
