Circular Saw Blades Bosch 2608640506 Multi Material 190mm 30mm

Multi Material Circular Saw Blades Bosch 2608640506 Multi Material 190mm 30mm are designed to provide versatile cutting performance across wood, non-ferrous metals, aluminium, plastics, epoxy and similar materials. The blade has a 190 mm diameter and a 30 mm bore, and combines precision-ground carbide teeth with a dimensionally stable SK5 hardened steel body (> 40 HRC). Expansion slots in the blade reduce vibration and heat build-up, improving cutting accuracy and extending service life. HLTCG (High-Low Triple Chip Ground) tooth geometry increases robustness for abrasive tasks while maintaining clean cut edges.

Advantages

The combination of precision-ground carbide teeth and a hardened SK5 steel base ensures durability and consistent cutting performance. Expansion slots lower vibration and noise while reducing thermal deformation during prolonged use. The HLTCG tooth design balances aggressive material removal with fine finish quality, making the blade suitable for a range of materials. A 30 mm bore fits standard saw arbors and the 190 mm diameter offers a good balance between cutting depth and compatibility with compact circular saws.

Suitable for

• Crosscuts and rip cuts in soft and hardwoods
• Cutting non-ferrous metals and aluminium sheets
• Trimming and shaping plastics and acrylics
• Working with epoxy and composite panels
• General renovation and DIY tasks requiring multi-material capability

How to use

Ensure the saw is unplugged or the battery is removed before fitting the blade. Mount the blade on a compatible 30 mm arbor, making sure it is correctly oriented according to the rotation arrow. Tighten the arbor nut to the manufacturer’s recommended torque. Adjust cutting depth and safety guards before operation. Use steady feed rates appropriate for the material and avoid forcing the blade through thick or highly abrasive materials. Allow the blade to reach full speed before the cut and let it coast to a stop after finishing the cut.

Recommendations

Use appropriate personal protective equipment including eye protection, hearing protection, and gloves. For metal and abrasive materials, reduce feed speed and use coolant or intermittent cuts when applicable. Inspect the blade regularly for wear or damage and replace it when carbide teeth are chipped or the finish quality deteriorates. Follow the circular saw manufacturer’s instructions for maximum RPM and compatible materials.
