Circular saw blade AWTools AW48455, 130 g weight

AWTools AW48455 is a circular saw blade manufactured from laser-cut carbon steel and fitted with tungsten-carbide teeth. The blade is designed as a replaceable cutting accessory for compatible stationary and portable saws. It includes expansion slots to reduce heat buildup and prevent deformation, and is supplied with a 30 mm bore plus 22 mm and 16 mm reduction rings to fit a range of arbors; smaller 115–125 mm variants use a 22 mm bore. The tooth geometry features alternating bevels and a 10° positive hook angle, with an approximate kerf width of 4.5 mm, making it suitable for general woodworking and cutting of hard plastics.

Advantages

The combination of a carbon steel body and tungsten-carbide teeth provides extended tooth life and consistent cut quality. Laser cutting ensures dimensional accuracy of the blade blanks while expansion slots help control thermal expansion and reduce the risk of blade warping under load. Multiple reduction rings and a common bore size increase compatibility with different saw arbors, and the alternating bevel tooth pattern with a positive hook angle offers efficient, controlled cutting performance across a variety of materials.

Suitable for

• Crosscutting hardwood and softwood
• Angular cuts in wood-based panels
• Cutting hard plastics and composite materials
• Replacement or spare blade for stationary and portable circular saws

How to use

Select the appropriate arbor reducer for your saw so the blade mounts concentrically on the spindle. Secure the blade according to the saw manufacturer’s instructions, ensuring the teeth point in the correct rotational direction. Verify blade tightness and that the saw guard and safety devices are correctly positioned before switching the saw on. Allow the blade to reach full speed before beginning the cut, feed the workpiece steadily, and avoid excessive lateral forces that could deflect the blade or damage the teeth.

Usage recommendations

Use appropriate personal protective equipment, including eye and hearing protection and a dust mask when cutting. Match blade RPM ratings to your saw’s operating speed and avoid prolonged continuous cutting that can cause overheating; allow the blade to cool if signs of heat build-up or burning appear. For best results on fine crosscuts and reduced tear-out, use a suitable zero-clearance insert and support the workpiece to minimize splintering.
