Metabo STB 18 L 90

Metabo STB 18 L 90: Workshop Positioning & Cutting Capabilities

Designed from the ground up for vibration-damped handling, the Metabo STB 18 L 90 is Metabo’s high-precision answer for finish carpenters navigating complex scribe lines. The balanced Barrel Grip chassis operates in lockstep with the 18V Lithium-Ion drivetrain, enabling the Metabo STB 18 L 90 to produce smooth, chip-resistant edge faces across challenging materials.

Metabo STB 18 L 90 is engineered for dependable woodworking precision and clean curve severance. Features 18v lithium-ion, multi-stage orbital action, and tool-free T-shank blade changes for jobsite and home remodeling projects.

Rated by the manufacturer for depths up to 3-1/2 in. (90 mm) in natural wood, 3/8 in. (10 mm) in metal channel, and 13/16 in. (20 mm) in non-ferrous bars, the Metabo STB 18 L 90 is well-equipped for HVAC openings, electrical gang boxes, and custom furniture contours.

Motor Architecture & Vibration Damping Dynamics

Engineered for steady workshop duty, the 18V Lithium-Ion motor in the Metabo STB 18 L 90 produces a responsive 700–3.000 SPM cadence. Balanced rotational counterweights minimize lateral tool wander, helping woodworkers maintain perpendicular cut faces across solid stock.

By eliminating the high overhanging handle, the barrel-style body of the Metabo STB 18 L 90 delivers exceptional feedback through the fingertips. Rubberized touchpoints along the cylindrical housing absorb vibration, ensuring precise tracking when trimming scribe lines along irregular masonry or drywall.

Shoe Base Engineering, Bevel Accuracy & Cut-Line Clarity

Engineered with a die-cast alloy foot, the Metabo STB 18 L 90 glides steadily across sheet goods without marring pre-finished veneers. Left-and-right bevel adjustments up to 45 degrees enable accurate chamfer cuts, complemented by effective forward debris ejection.

Keyless Blade Clamp & Orbital Action Settings

Blade swaps on the Metabo STB 18 L 90 are completely tool-free: an all-metal quick-release clamp lever opens the locking jaws, allowing spent or scalding-hot blades to drop out cleanly without direct fingertip contact. The mechanism accepts all universal T-shank blades.

The Metabo STB 18 L 90 incorporates a multi-stage orbital action selector that tailors the blade’s forward stroke swing to the material at hand:

• Setting 0: Vertical reciprocation without orbital swing. Essential for sheet metals, copper tubing, PVC, and chip-free cuts in double-sided melamine veneers.
• Setting 1: Subtle orbital oscillation. Recommended for dense hardwoods like white oak, hard maple, and birch plywood to balance edge smoothness with cut progress.
• Setting 2: Medium pendulum swing. The workhorse setting for general softwood framing (2x4, 2x6) and construction lumber.
• Setting 3: Maximum aggressive orbital thrust. Delivers blistering feed speed for rough dimensioning, timber framing, and demolition work where speed outweighs edge cosmetics.

Frequently Asked Questions About the Metabo STB 18 L 90

Does the Metabo STB 18 L 90 come packaged with a battery and charger?

In its standard bare-tool configuration, the Metabo STB 18 L 90 ships as tool-only to save money for users already invested in the 18V Lithium-Ion battery ecosystem. Retail combo kits that bundle lithium-ion packs and fast chargers are also widely stocked.

What battery size offers the best balance on the Metabo STB 18 L 90?

For general workshop and cabinetry tasks, a 4.0 Ah or 5.0 Ah 18V Lithium-Ion battery provides the optimal equilibrium between extended continuous runtime and tool maneuverability. Ultra-compact 2.0 Ah slim packs are great for overhead scribing, while larger 6.0 Ah to 8.0 Ah packs suit high-volume jobsite framing.

Can I use universal Bosch-style T-shank blades in the Metabo STB 18 L 90?

Yes. The keyless clamp is fully compatible with all standard T-shank blades from Bosch, Diablo, Milwaukee, DEWALT, and Festool, allowing you to choose any tooth geometry or material rating.
