Sliding Mitre Saw Bosch GCM 254 Professional — 5000 RPM, 25.4 cm Blade, Mitre L47°/R52°

Bosch GCM 254 Professional is a sliding mitre saw with a 254 mm (25.4 cm) blade and a maximum no-load speed of 5,000 RPM. Designed for accuracy and repeated performance in carpentry and joinery, this mitre saw combines a sliding mechanism with mitre adjustment left 47° and right 52° to handle crosscuts, mitres and angled joinery. The tool includes a visible direct laser for line guidance, a detachable box extension to support longer workpieces and a length gauge for consistent cutting lengths. Compact dimensions (W 477 × D 559 × H 567 mm) allow placement in workshops where space is limited while preserving stability during operation.

Advantages

The sliding action increases cutting capacity compared with fixed-head saws, enabling longer workpieces to be processed without repositioning. Precise angle settings and mitre stops at L47°/R52° make repeated mitres simple to set and reproduce. The integrated visible direct laser improves cut-line visibility for accurate alignment. A detachable box extension and length gauge give additional support and repeatability when working with longer sections. The combination of a 254 mm blade and a 30 mm blade bore provides a balance between cutting depth and blade stability for typical woodworking tasks.

Suitable for

• Crosscuts and mitre cuts in softwood and hardwood boards
• Production of mouldings, frames and skirting boards
• Angled joinery and trim work in carpentry workshops
• On-site installation tasks that require a compact, portable saw

How to use

Set the saw on a stable, level surface and secure the workpiece against the fence. Select the required mitre angle using the mitre scale and lock it in place; verify the laser line for precise alignment. For longer workpieces attach the detachable box extension and use the length gauge to set repeat cut lengths. Start the saw, allow the blade to reach full speed, then smoothly lower the cutting head through the material while maintaining a steady feed. After the cut, release the trigger and wait for the blade to stop before removing the workpiece or making adjustments.

Usage recommendations

Use blades matched to the material type and desired finish; a fine-tooth blade delivers cleaner edges on trim and mouldings, while a general-purpose carbide-tipped blade suits rougher cuts. Always wear appropriate eye, hearing and dust protection. Check blade condition and tightness before each use and follow manufacturer maintenance intervals for lubrication and inspection of the sliding mechanism to ensure longevity and consistent accuracy.
