Porter-Cable Comprehensive Guide to the Porter Cable Laminate Trimmer and Underscribe Base
Page 10

FUNCTIONAL DESCRIPTION

FOREWORD

Porter-Cable Laminate Trimmers are designed for flush and bevel trimming laminated plastics, phenolics, and other similar materials having a bonding agent too hard to be trimmed with ordinary tools.

The Tilt-Base model allows trimming into corners inaccessible to standard trimmers and to trim laminated surfaces joining at angles of 45° to 90°. This feature eliminates the need for hand-trimming in many applications.

The Off-Set Base Trimmer is designed for trimming into the corner of a back splash and trimming narrow ledges which are already mounted against a wall or another surface.

The Underscribe Base is designed for making accurate “butt” joints in laminated plastics, phenolics and other similar materials. The Underscribe Base is used with the Model 7301 Trimmer Motor and the 43109 Trim Bit.

SELECTING THE BIT

These trimmers are equipped with a 1/4" diameter collet to accept laminate trimming bits having 1/4" diameter shanks. Bits are available as an accessory.
