Built for aluminum profiles that require both straight and angled cuts, the PMI-20 Miter Upcut Saw combines a 20-inch blade platform with adjustable miter positioning and controlled upcut operation. The saw provides ±45° miter capability for framing components, extrusions, and other nonferrous sections where accurate end angles are part of the finished geometry. Full-width clamping helps keep the profile secure as the cutting angle changes, giving fabricators a flexible solution for recurring 90° and miter cutoff work.
PMI-20 Miter Upcut Saw Features:
The PMI-20 gives fabricators angular cutting capability without moving to a fully automated CNC miter platform. This 45 degree aluminum miter saw allows the saw head to be positioned for straight and angled cuts, making it useful for aluminum extrusions, framing components, and other profiles that require repeatable mitered ends.
Material control becomes especially important when the saw head moves away from 90°. The PMI-20 uses a full-width clamping arrangement to secure the workpiece across the cutting range. This full width clamping aluminum saw configuration helps stabilize profiles during straight and miter cuts while reducing the setup required when switching between different angles.
The 20 inch miter upcut saw keeps the blade below the work surface until the cutting stroke begins, providing a controlled cutting path through aluminum and other nonferrous profiles. The combination of upcut motion, adjustable miter positioning, and secure workholding gives manufacturers a flexible platform for producing both square and angled profile cuts.

The Pat Mooney PMI-20 Miter Upcut Saw is a semi-automatic double-miter upcut saw for aluminum and other non-ferrous profiles. Its operating format and working range define where it fits within aluminum and non-ferrous cutoff production.
A 20-inch blade, 7.5-hp motor, 2,800 rpm speed, air-over-oil feed, and adjustable clamping support 45-degree left and right miters. Published maximum capacity is 5.9 inches high by 11 inches wide. Final machine selection depends on the complete material range, profile or plate geometry, finished length, tolerance, production volume, blade requirements, clamping, material support, and part handling.
Common applications include:
The saw head positions through 45 degrees left and right for straight and angled parts.
The clamp covers the working width and secures material on both sides of the blade.
The 5.9 × 11-inch envelope covers broader profiles than the PMI-18.
Manual length and angle setup suits changing jobs without a full automatic program.
The saw makes straight cuts and miters through 45 degrees left and 45 degrees right.
Maximum capacity is 5.9 inches high by 11 inches wide at the reference position. Available clearance changes with angle and profile orientation.
The full-width clamp does not require repositioning between straight and angle cuts and holds material on both sides of the blade.
Pat Mooney lists Go2 PD-50 automatic stops and Go2 PD-100 stop/pusher systems as compatible options for PMI saws.
The CNC version fits repeat batches requiring powered angle positioning, a built-in servo pusher, and touchscreen job control. The semi-automatic model fits more operator-directed work.
