Circular HSS metal saw blade KWB 187220, 300 mm diameter, flexible

The KWB 187220 circular saw blade is a 300 mm diameter HSS metal cutting blade designed for clean, controlled cuts in thin to medium metal sections. Constructed from high-speed steel and specified as flexible, this blade is intended for compatibility with portable and stationary metal-cutting saws that accept 300 mm blades. The flexible HSS construction reduces chipping and tolerates slight deflection during operation, helping to maintain cut quality on a variety of ferrous and non-ferrous materials.

Advantages

The HSS construction provides high hardness and wear resistance for extended cutting performance in metalworking applications. Flexibility in the blade design helps absorb small deflections and reduces the risk of tooth breakage, supporting more consistent kerf quality. The 300 mm diameter offers a balance between cutting depth and machine compatibility for many saw types used in workshops and on-site jobs. Overall, the blade delivers precise, repeatable cuts when used with suitable equipment and cutting parameters.

Suitable for

• Cutting thin to medium-thickness steel and other ferrous metals
• Cutting non-ferrous metals such as aluminum and brass
• Use with portable metal-cutting saws that accept 300 mm blades
• Use with stationary metal-cutting saws that accept 300 mm blades

Key specifications

• Blade diameter: 300 mm
• Material: high-speed steel (HSS)
• Design characteristic: flexible blade construction to reduce chipping and tolerate slight deflection
• Intended application: metal cutting (ferrous and non-ferrous)
• Compatibility: for saws that accept 300 mm circular blades

How to use

Install the 300 mm HSS blade on a compatible metal-cutting saw following the tool manufacturer's instructions, ensuring correct mounting direction and secure fastening. Set appropriate cutting speed and feed for the material being cut — lower speeds and steady feed rates are generally recommended for thicker or harder metals. Use cutting fluid or coolant when cutting tougher alloys to reduce heat buildup and extend blade life. Observe all safety precautions for metal cutting, including eye protection, hearing protection, and secure clamping of workpieces.

Usage recommendations

For best results, match blade speed and feed to the workpiece material and thickness, keep the blade and work area cool with suitable lubricant or coolant when necessary, and inspect the blade before each use for signs of damage. Replace the blade if excessive wear or tooth damage is detected to maintain cutting quality and operator safety.
