All the features of our MAST-R-LIFT™ and more. The MAST-R-LIFT EXCEL offers two great features, a micro-adjust dial allows you to zero-out the MICRODIAL and then accurately crank the router up at a ratio of 1/64 inch per 1/4 turn of the crank. Extremely precise adjustments to the router bit cutting height can now be performed faster and with more precision than ever before.Another feature is an integrated dust port that is machined into the lifts housing underneath the tabletop. This design virtually removes chips just as they are cut by the router bit. This design feature will literally extend the working life of the router motor. This design removes the chips before they can reach the router, ultimately prolonging the life of the motor through more efficient chip extraction. The black phenolic MAST-R-TOP includes our MAST-R-TRAC with a Miter Track in between two T-tracks. This heavy gauge 6061 aluminum extrusion is anodized in red and ready to attach jigs, hold-downs or a miter gauge. The lift mechanism is raised and lowered by an offset right-angle gearbox positioned on the right side, under the tabletop. The new MAST-R-LIFT EXCEL¿ will accept the Porter Cable model 7518 out of the box, and accepts additional routers with cylindrical motor housings with the use of a reducer collar (sold separately). The centerhole in the tabletop is machined with a 3-5/8 diameter TAB-LOC¿ centerhole to accept up to a 3-1/2 diameter raised panel bit. An insert ring with a 1-1/2 diameter centerhole for most smaller bit diameters, an insert ring wrench, starting pin and hex key wrench are also included. Additional insert ring sets are available separately.
