The PMI-20 24 expands manual miter capability to a 24-inch blade and a 14.6-inch-wide cutting envelope. It’s a practical fit for larger architectural, transportation and fabricated aluminum profiles that need angles up to 60° left or right but do not require an automatic pusher or CNC production cycle.
PMI-20 24 Miter Upcut Saw Features:
The PMI-20 24 expands angular cutting beyond a conventional 45° miter range. This 60 degree aluminum miter saw positions the saw head from 60° left to 60° right, giving fabricators greater flexibility when producing extrusions and components with more aggressive end angles. The wide miter range also allows straight and angled parts to be processed on the same cutting platform.
A larger blade and cutting envelope give the 24 inch profile miter saw room to process aluminum sections up to 7.87 inches high. The upcut configuration keeps the blade below the work surface before the cutting stroke, while controlled blade feed and secure workholding support repeatable cutting across changing profile sizes and miter angles.
With capacity for material up to 14.6 inches wide, the PMI-20 24 can accommodate broad sections that exceed the envelope of smaller miter saws. This 14.6 inch wide extrusion saw gives manufacturers additional room for larger aluminum profiles while retaining the angular flexibility needed for mitered components, framing sections, and other nonferrous production work.

The Pat Mooney PMI-20 24 Miter Upcut Saw is a semi-automatic double-miter upcut saw for aluminum profiles and other non-ferrous sections. Its operating format, head arrangement, and working range define where it fits within aluminum and non-ferrous production.
A 7.5-hp motor drives a 24-inch blade at 2,000 rpm. The head rotates through 60 degrees left and right, while air-over-oil feed and adjustable vertical and horizontal clamps support a published 7.8-inch-high by 14.6-inch-wide capacity. Final machine selection depends on the complete material range, profile geometry, required angles or features, finished length, tolerance, production volume, blade requirements, clamping, material support, and part handling.
Common applications include:
The rotating head covers straight cuts and acute left- or right-hand miters without repositioning the stock.
The 7.8 × 14.6-inch envelope accommodates profiles beyond the reach of the standard PMI-20.
Air-over-oil feed regulates the upcut stroke through hollow, thin-wall, and heavier sections.
Vertical and horizontal clamp pressure can be set around profile shape and surface requirements.
The 24-inch model increases blade diameter and published capacity to 7.8 × 14.6 inches and extends the miter range to 60 degrees left and right.
The saw head rotates through 60 degrees in either direction, allowing 90-degree crosscuts and left- or right-hand miters.
No. This is a semi-automatic saw: the powered cutting stroke is controlled, while length and angle setup remain operator directed.
The listed maximum is 7.8 inches high by 14.6 inches wide. Usable clearance changes with miter angle and profile orientation.
Blade selection, profile support, clamp pressure, head angle, feed rate, alloy, wall thickness, and lubrication all affect squareness, burr, and finish.
