Thirty years ago we introduced inserted mandrel and wiper tooling to the tube-bending industry. Our continuous improvement of inserted tooling design and manufacture (via Datafacturing®) has set the standard.

Our mandrel tooling line features the following:

• Standard tooling available for round, square, and rectangular tubing.
• Standard tooling available for tube diameters from .875″ to 5.563″ (22mm to 140mm).
• Plugs available for smaller diameters; custom ball-mandrels for larger diameters.
• 1-“D” bending capacity.
• Large nose radius for most jobs and sharp nose radius for stainless steel, titanium, tight-radius, and high-pressure tube-bending.
• Regular-pitch, close-pitch, and extra close-pitch balls.
• Heavy-duty, single-piece, snap-together poppet-style links in all sizes.
• Vented mandrel body for “through the mandrel” automated lubrication.
• Wide wrench flats for easier attachment to the machine.
• Dozens of mandrel thread specifications (both inch and metric) are standard at no extra cost.
• Nickel-aluminum-bronze* or hard-chromed alloy steel mandrel balls and nose inserts.
• Sold as complete assemblies, sub-assemblies, and individual replacement components.
  • Insert (or mandrel) link screws.
  • Assembly kits for links (detent ball, detent spring, and retaining ring).
  • Assembly tools for our poppet-style links.

* For mandrels smaller than 4″ (101.6mm) in diameter. For larger mandrels, non-nickel aluminum-bronze is available.
