End Finishing Tooling Definitions

End finishing tooling prepares or forms the end of a tube after cutting or bending. Common operations include squaring, deburring, flaring, double flaring, beading and flanging.

Squaring and Deburring Blades

[LINK: Blades category] Squaring and deburring blades face the end of a round tube or pipe square and remove burrs from the ID and OD in a single operation. New blades in stock — call for pricing.

Blade types:

  • CS-1, VS-1, TS-1, K-1, TK-1, CK-1, K-2, TK-2
  • CS-1-1/8, VS-1-1/8, TS-1-1/8
  • CS-2, VS-2, TS-2
  • CS-5, VS-5, TS-5

Squaring and Deburring Heads

[LINK: Squaring/Deburring category] Squaring and deburring heads hold the blades on the end finishing machine.

Head types:

  • SB-1
  • SB-2
  • SB-3
  • SB-6
  • SB-8

Beading Dies

[LINK: Beading category] Beading forms a raised ring, or bead, near the end of a tube. Standard beads are made to MS33660. Beaded tube ends are used for hose-to-tube connections, low pressure fuel lines, exhaust tubing and similar applications where a hose is clamped over the tube. Beading tooling consists of a two-piece split die, a beading head, and beading tips, beading arbors or beading rollers.

Flaring Dies

[LINK: Flaring category] Flaring expands the tube end into a cone to seat against a flare fitting. Standard single flares are made to MS33584 and double flares to MS33583. Flaring dies can be made for 37° and 45° flares. Flared tubes are used for hydraulic lines, automotive and aircraft fuel lines, and heating and cooling lines. Standard flaring centers are used on mild steel, copper, brass and aluminum; tungsten carbide flaring centers are used on harder materials such as stainless steel and titanium.

Double Flaring Dies

[LINK: Double Flare category] A double flare folds the tube end back on itself before forming the cone, creating a two-wall flare. Double flares are stronger and more resistant to cracking than single flares and are commonly used on softer or thin-wall tubing. Standard double flares are made to MS33583.

37° vs. 45° Flares

37° flares are the standard for hydraulic and aerospace fittings (AN, JIC and MS standards). 45° flares are common in automotive brake lines and refrigeration and HVAC lines. Flaring dies and fittings must use the same angle.

Flanging Dies

[LINK: Flanging category] Pipe flanging forms a flange directly on the end of the pipe, removing the need for a welded-on flange. Flanged pipe ends are used in power plants, chemical plants, refineries and other process piping.
