The Porter-Cable 97310 is a 1/4-inch Laminate Trim Kit. One motor and three bases make the laminate trim kit perfect for installers. A powerful 5.6 Amps AC/DC motor turns 30000 RPM to make quick work of trimming tasks. The motor has 100% ball bearing construction for durability and smooth operation and a metal lower motor housing for heat dissipation. A built-in spindle lock and flat-top design allow for quick and easy one-wrench bit changes. The 1/4 inches collet accepts laminate trimming bits as well as router bits. The three bases each have their own specialty. The tilting base tilts 30° to the right and 45° to the left to allow use where the motor prevents other laminate trimmers from cutting close to vertical obstructions.
