WIPERS

Inserted, Solid-Body, and High Pressure Wiper Dies and Components for Rotary-Draw Tube Bending

Bend Tooling’s industry-leading inserted wiper die is our most popular product. Over the past thirty years we have perfected the design and manufacture of our inserted wiper line, and no one else comes close to our quality, price, and speed of delivery.

We also manufacture traditional “aircraft-quality” square-back solid-body wiper dies plus we have a resharpening service for these tools (including those made by our competitors). Square-back solid-body wiper dies are excellent for high-pressure tube-bending jobs that require the wiper to be set at zero-rake. However, they are relatively costly to purchase and then recondition as they wear.

Whether inserted or solid, all of our wipers have a fully machined feathered edge. Unlike our competitors, there is no manual honing or sanding of the feathered edge. Bend Tooling precision machines this essential attribute of the wiper die. Do not settle for less.

Our wiper tooling line features the following:

  • Standard inserted and solid wipers available for round tubing; custom solid-body “flat” wipers for square and rectangular tubing.
  • Standard tooling available for tube diameters from .875″ to 5″ (22mm to 125mm).
  • Precision machined feathered edge.
  • Simple-sweep feathered edge geometry for most jobs and off-set geometry for stainless, titanium, and other high-pressure tube-bending.
  • Bore and radius faces micro-finished to 32 or better.
  • Dozens of standard mounting patterns (both inch and metric) are available at no extra cost.
  • Half-round alloy steel holders standard for inserted wipers.
  • Wiper inserts available in aluminum-bronze, hard-chromed, and leaded steel.
  • Inserts attach to the holders through the bore for easier replacement on the machine.
  • Square-back aluminum-bronze bodies standard for solid wipers.
  • Sold as complete assemblies and individual replacement wiper inserts.
  • Wiper insert mounting screws available separately.

Understanding Wiper Set-up with Standard-Style Inserts

Standard-Cut Wiper Proper Positioning

Wiper tip raked slightly to ensure tip will not become pinched between tube and bend die. Full contact with bend die for maximum support.

Standard-Cut Wiper Zero Rake Angle

Wiper tip may become pinched between tube and bend die. This may damage the tip or lead to imprint on tube.

Standard-Cut Wiper Zero Rake Angle Pulled back from Tangent

No support to the heal of the wiper insert will allow the wiper tip to flex during bending. Wrinkles may form.

Understanding Wiper Set-up with “Aerospace” (Aero) Inserts

Aero-Cut Wiper Proper Positioning

Very little or no rake angle. Full contact with bend die for maximum support.

Aero-Cut Wiper Negative Rake to bring tip closer to tangent

Back of wiper insert may drag against tube causing marking. This may also lead to clamp slippage and wrinkles.

Aero-Cut Wiper Too much Rake Angle Too close to tangent

No support to feathered edge of wiper insert will lead to wiper tip failure.
