Circular saw blade AWTools AW48477, 850 g weight, for wood and general-purpose cutting

AWTools AW48477 circular saw blade, 850 g, is a replaceable blade designed for general-purpose cutting of wood and related materials. Made of laser-cut high-carbon steel with tungsten-carbide teeth, the blade combines basic structural strength with wear-resistant cutting edges. Expansion slots reduce heat buildup to help maintain blade shape during prolonged use. The blade features alternating bevel teeth, a 10° positive hook angle and an approximate kerf width of 4.5 mm. It is supplied with a 30 mm bore and includes 22 mm and 16 mm reduction rings; smaller 115–125 mm versions have a 22 mm bore. The blade is intended for use on stationary and portable circular saws where the blade dimensions and arbor match.

Advantages

The AWTools AW48477 offers a balance of durability and cutting quality through tungsten-carbide teeth bonded to a carbon-steel body and laser-cut manufacturing for consistent flatness. Expansion slots help control thermal expansion and reduce the risk of distortion when cutting demanding materials. The supplied reduction rings increase compatibility with different arbor sizes, and the 10° positive hook angle assists efficient feed and clean cutting of wood and wood-based panels.

Suitable for

• Crosscuts and angled cuts in hardwood and softwood
• Cutting wood-based panels such as plywood and MDF
• Trimming and ripping tasks on construction sites and workshops
• Cutting hard plastics where a clean edge is required
• Use on compatible stationary and portable circular saws

How to use

Ensure the saw is disconnected from power before replacing the blade. Match the blade diameter and bore to the saw spindle and, if required, fit the appropriate reduction ring. Secure the blade according to the saw manufacturer's instructions, checking correct rotation direction and clamping torque. When cutting, use steady feed pressure and the appropriate speed for the material. Allow the blade to decelerate fully before handling after use, and inspect the blade regularly for wear, chipped teeth or heat damage.

Usage recommendations

Use appropriate personal protective equipment (eye, ear and hand protection) and a dust extraction system where possible. For best results on fine-finish cuts, check blade sharpness and replace the blade when signs of burning, excessive chipping or loss of cut quality appear. Avoid prolonged cutting under heavy load to reduce heat buildup despite the expansion slots.
