Circular saw blade AWTools AW48459, 420 g weight

AWTools AW48459 circular saw blade, weighing 420 g, is manufactured from laser-cut carbon steel with tungsten-carbide teeth for extended sharpness and consistent cut quality. The blade includes expansion slots to reduce heat build-up and limit deformation, and features alternating bevel teeth with a 10° positive hook angle and an approximate kerf width of 4.5 mm. It is supplied with a 30 mm bore and two reduction rings (22 mm and 16 mm) for compatibility with a wide range of saw arbors; smaller diameter 115–125 mm variants are supplied with a 22 mm bore. The blade is intended for use on compatible stationary and portable circular saws and is suitable for transverse and angled cutting of hardwood, wood-based materials and hard plastics.

Advantages

The combination of laser-cut carbon steel body and tungsten-carbide teeth provides improved durability and longer service life compared with plain-tooth steel blades. Expansion slots reduce thermal stress during continuous cutting, helping to maintain blade flatness and accuracy. Alternating bevel teeth with a positive hook angle produce clean crosscuts and smooth angled cuts in a variety of materials. Included reduction rings increase mounting flexibility across different saw models and arbor sizes.

Suitable for

• Crosscuts and miter cuts in hardwood
• Cuts in plywood, MDF and other wood-based panels
• Cutting hard plastics and laminates
• Use in stationary table saws and portable circular saws when correctly mounted

How to use

Before mounting the AWTools AW48459 blade, ensure the saw is disconnected from power and that the arbor and bore adapter are clean and free of debris. Fit the appropriate reduction ring if required to match your saw arbor diameter. Secure the blade according to the saw manufacturer's instructions, making sure the rotation direction marked on the blade matches the saw's rotation. Check blade alignment and tighten the arbor flange to the recommended torque. Select feed rate and cutting speed appropriate for the material; use steady, even feed to avoid overloading the blade. After use, allow the blade to cool before handling or storing.

Usage recommendations

Confirm compatibility with your saw model and observe all safety guidelines for guards, push-sticks and eye and hearing protection. For best results when cutting hardwood or plastics, use a steady feed rate and avoid excessive lateral pressure. Regularly inspect the tungsten-carbide teeth for wear and replace the blade when cut quality degrades or if damage is visible.
