## Long description

Irwin 100 mm semi-circular HSS saw blade for oscillating multi-tools and multifunctional sanders is designed for precise trimming, plunge cuts and work in confined radii. The half-round profile allows access to curved and recessed areas while the high-speed steel (HSS) construction provides wear resistance and consistent cutting performance. This accessory is intended for use with compatible oscillating tools and multifunctional sanders to cut a variety of materials where a semi-circular geometry is required.
Advantages
The semi-circular 100 mm shape enables controlled plunge cuts and radius work in limited spaces. High-speed steel construction offers improved edge life and maintains cutting sharpness under moderate load. The blade’s geometry reduces vibration during operation and supports accurate guidance for straight and curved cuts. Compatibility with standard oscillating tool mounting systems simplifies installation and replacement.
Suitable for
 Trimming and shaping wood and composite materials in confined areas
 Plunge cutting and notching in metal sheets and profiles
 Working on corners, curves and recessed details
 Renovation tasks where controlled semi-circular cuts are required
Key specifications
 Blade shape: semi-circular (half-round)
 Blade diameter/width: 100 mm
 Material: high-speed steel (HSS)
 Intended tool type: oscillating multi-tool / multifunctional sander
 Typical applications: plunge cutting, trimming, radius cuts
How to use
Select an oscillating multi-tool or multifunctional sander that accepts semi-circular blades and ensure the tool is unplugged or its battery removed before fitting the blade. Mount the HSS semi-circular blade onto the tool’s adapter according to the tool manufacturer’s instructions and secure it firmly. Start cutting at low speed to position the blade, then increase speed as appropriate for the material. Use steady, controlled feed pressure and avoid forcing the blade to minimize wear. For metal cutting, apply cutting oil if recommended for the material and maintain a consistent cutting motion to prevent overheating.
Usage recommendations
Use appropriate personal protective equipment (safety glasses, gloves and hearing protection), choose the correct speed for the material, and replace the blade when cutting performance or edge integrity diminishes to maintain safety and quality of cuts.
