With best-in-class dust extraction, intuitive adjustments, and quality German engineering, this saw sets the standard for what a miter saw can be.

Key Features & Benefits

Unmatched Precision

• Rail forward design with robust 30mm-diameter rails spaced wide apart, eliminating head play for smooth, accurate cuts every time.
• Fully-adjustable dual-line lasers clearly define the material to be removed, enabling precise cut placement from the left or right side.
• Stainless steel, etched miter scale positioned far from the axis of rotation for extreme accuracy down to fractions of a degree.
• Micro-adjustable bevel angle with up-front rotary knob and large, easy-to-read gauges on both sides of the saw.

Compact & Portable Design

• Rail forward design allows the saw to be placed directly against a wall for all cutting tasks, maximizing workspace.
• Lightweight at approximately 50.9 lbs (24.3 kg) with ergonomically designed carrying positions that keep the center of gravity close to your body.
• Compact dimensions of 28" x 19-3/4" x 18-1/2" (713 x 500 x 470 mm) with a locking head for secure transport and storage.
• Deck height matches Festool Systainer storage containers for convenient material support on the jobsite.

Superior Dust Extraction

• Achieves up to 91% dust extraction efficiency when paired with a 36mm dust extractor hose.
• Flexible, removable rubber dust hood behind the blade deflects waste into a directional dust port.
• Dual dust extraction connection diameters of 1-1/16" and 1-7/16" (27/36 mm) for compatibility with Festool extractors.

Powerful Motor & Smart Electronics

• 1,600-Watt direct drive motor for efficient energy transfer to the blade, resulting in cleaner, more accurate cuts.
• MMC variable speed electronics (1,400–3,600 RPM) allow you to match blade speed to the material, preventing burning or melting.
• Magnetic brake reduces blade spin-down time for safer, faster workflow.
• Two-stage trigger helps prevent accidental activation.

Exceptional Cutting Capacity

• 10-1/4" (260 mm) saw blade with a thin kerf design reduces motor load and improves cut quality.
• Special cutting position provides vertical capacity up to 4-3/4" x 3/4", rivaling many 12" miter saws.
• Cuts crown moulding up to 6-5/8" in the nested position at both 45° and 90°.
• Miter range of 50° left to 60° right; bevel range of 47° left and right.
• Built-in trenching capability for creating lap joints and dadoes with a simple knob adjustment.

Ease of Use & Convenience

• Counter spring balanced bevel holds any angle without locking, making adjustments less tedious and more accurate.
• FastFix blade change system locks the arbor and trigger with a single knob, allowing one-handed blade swaps.
• Included MiterFast angle transfer device for quick, calculation-free transfer of inside and outside angles to the saw.
• Keyed, non-slip material clamp with lever-actuated cam-lock and rubber pad to protect workpieces.
• Center-positioned handle allows cutting with either hand for improved visibility.
• Onboard storage for the power cord and arbor tool protects accessories during transport.

Warranty & Support

• Backed by Festool's 3-year wear-and-tear warranty, 2-day standard repair time, and 1-month satisfaction guarantee.
