Lame circolari Bosch Optiline Wood 2608640440 250 mm 30 mm

The Bosch Optiline Wood Circular Saw Blade 2608640440 with a 250 mm diameter and 30 mm bore is designed for precise cutting of various wood materials. The blade combines a precision-ground carbide tooth set with a dimensionally stable SK5 hardened steel body (> 40 HRC). Expansion slots reduce vibration and heat build-up for smoother operation. Compatible with handheld circular saws, mitre saws, sliding mitre saws and table saws, this blade is intended for straight and cross cuts in solid wood, laminated panels and other wooden workpieces. The blade uses ATB (Alternate Top Bevel) tooth geometry; a higher tooth count yields cleaner finishes, while fewer teeth prioritise faster, more aggressive material removal.

Advantages

The precision-ground carbide teeth provide consistent cutting performance and extended wear resistance compared with non-tipped blades. The SK5 hardened steel core maintains flatness and dimensional stability during use, supporting accurate cuts. Expansion slots integrated into the body reduce vibration and noise while limiting heat generation, which helps preserve tooth hardness and cutting accuracy. ATB tooth geometry offers versatile cutting characteristics across wood types and panel materials.

Suitable for

• Crosscuts and rip cuts in solid wood
• Cutting laminated and veneered panels
• Trimming doors, skirting boards and window frames
• General woodworking tasks with handheld, mitre or table saws

How to use

Ensure the saw is unplugged or the battery is removed before fitting the blade. Mount the blade with the teeth oriented in the direction of rotation indicated on the saw and secure the arbor flange and nut according to the tool manufacturer’s torque specifications. Select the appropriate blade speed and feed rate for the material and tooth count: use slower feed and higher tooth count for fine finishes, and faster feed with fewer teeth for rough or rapid cuts. Inspect the blade for damage or build-up before each use and clean or replace as required.

Recommendations

Use appropriate personal protective equipment (eye and hearing protection, dust mask) and a suitable dust extraction system when cutting wood. Match the blade tooth count and feed speed to the material for optimal finish and blade life. Avoid cutting metals or masonry with wood blades to prevent rapid wear or damage.
