Sleeveless Expendable Tooling

Mandrels

The mandrel, fitted with a sleeve, is used to coldwork the hole. West Coast Industries mandrels are made from highest quality vacuum-melted tool steel which has been double tempered and precision ground. Their useful life is related to the type and yield strength of the material to be coldworked, the amount of interference between the mandrel and the hole, wear due to a coldworking of the mandrel itself, and a slight abrasiveness of the lubricant on the inside of the sleeve.

  • Available in a number of lengths, based upon the stackup to be pulled. Unlike split sleeve mandrels, the working length is the same regardless if a flush nosecap or a nosecap extension is used.

  • Special sizes are available

WCI-CMX-10-0-1-20 5/16" nominal, 300 Puller, 2" stackup
WCI-CMX-12-0-2-30 3/8" nominal, 400 Puller, 3" stackup

Pilots

The pilot is used to support the split mandrel once the major diameter has passed through the hole to be coldworked. Pilots are ordered to match the length and size of the mandrel.

WCI-400P-20 Pilot used with 400 puller for all mandrel sizes. Two-inch length

Nosecaps

 

Nosecaps are used to transfer coldwork pull force from the workpiece to the puller gun. The nosecap is equipped with a lubricant system to transfer a thin-film lubricant to the surface of the mandrel. This protects the hole, while reducing pull force.

Flush Nose

Flush nosecaps are used where there is no restricted access.

WCI-300-NX-10-0

Nosecap for the 300 puller, to coldwork a 5/16" hole

WCI-300-NX-14-0

Nosecap for the 400 puller, to coldwork a 7/16" hole


Extension Nose

A nose extension is used in areas of limited access with both 300 series and 400 puller guns. A mandrel extension and pilot extension is included with the nosecap, so only the thickness of the material to be coldworked needs to be considered when determining mandrel length

WCI-300-ENX-8-0

Extension Nose for the 300 puller, to coldwork a 1/4" hole

WCI-400-ENX-16-0

Extension Nose for the 400 puller, to coldwork a 1/2" hole


Starting Drills

Starting drills create a hole ready for reaming to the pre-coldwork size.

  • Manufactured from high speed steel or cobalt
  • Used to create holes in new production work
  • All drills under 1/2" have straight shank, larger sizes have a stepped-down shank to accept standard chucks.

WCI-SDX-18-3 Start Drill for 39/64" nominal hole size

Reamers

Start Hole Size

Start hole reamers bring the hole to its pre-coldwork size. The non-cutting pilot helps guide the reamer into the pre-drilled pilot hole.

WCI-SRX-18-1-N Start reamer for 37/64" hole size
WCI-SRX-6-0 Start reamer for 3/16" nominal hole size

Final Size Reamers

The final size reamer cleans up the ridges left by the mandrel and leaves a smooth, round hole ready for countersinking or fastener installation. The non-cutting pilot is used both as a guide and to verify the hole has been coldworked.

WCI-FRX-14-3-4950 31/64" nominal hole size, reamed to .4950"

Go-No Go Gages

Go-No-Go gages can be purchased from West Coast Industries for on-line inspection of start hole, reamed holes, codlworked holes, mandrels and pilots.


Combination Gage

The combination gage is used to check the reamed, pre-coldworked start hole, with a go-no go end, while the other end verifies the hole has been coldworked.

Mandrel Wear Gages

Mandrel wear gages are available for every mandrel size. If the mandrel major diameter passes through the No Go gage, the mandrel is worn beyond its limit.

WCI-300-PDW-60-63 Check pilot for a 300 series puller, used with 6-0 through 6-3 mandrels
WCI-400-PDW Checks all 400 series mandrels

Inspection Pin

The inspection pin is used to check the mandrel major diameter. The gague diameter is precision ground to match the diameter of the pilot. Once inserted into the forward end of the split mandrel, it expands the mandrel to operational size. This allows the Go/No-Go gague to be used to check the diameter of the mandrel for wear.
