Circular saw blade AWTools AW48478 — weight 850 g

AWTools AW48478 is a circular saw blade made of high-quality carbon steel with laser cutting for a true running surface. The blade is equipped with tungsten-carbide teeth designed to retain sharpness longer and deliver precise, clean cuts. Expansion slots reduce heat build-up and help prevent deformation during sustained cutting. The blade has 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; 115–125 mm diameter variants use a 22 mm bore. The net weight of the product is 850 g.

Advantages

The combination of carbon steel body and tungsten-carbide teeth provides a balance of durability and cutting performance, while laser cutting improves flatness and concentricity. Expansion slots dissipate heat to maintain blade geometry under load, reducing the risk of warping. Alternating bevel teeth and a 10° positive hook angle produce efficient feed into material and consistent cut quality across hardwoods, wood-based panels and hard plastics. Included reduction rings increase compatibility with both stationary and portable saws.

Suitable for

• Crosscuts and angled cuts in hardwoods
• Cutting plywood, MDF and other wood-based panels
• Trimming and sizing hard plastics
• Use in stationary table saws and portable circular saws with matching arbor sizes

How to use

Install the AWTools AW48478 blade on a compatible saw following the saw manufacturer's instructions and ensuring the blade rotation direction matches the arrow on the blade. Fit the appropriate reduction ring if the arbor diameter of your saw differs from the blade bore, then secure the blade with the saw's flange and nut to the recommended torque. Verify blade runout before use and adjust if necessary. Choose feed speed and cutting depth suitable for the material: slower feed for dense hardwoods and a steady feed for panels and plastics. Allow the blade to cool between long cutting runs to avoid overheating despite the blade's expansion slots.

Usage recommendations

For best results use appropriate personal protective equipment, clamp the workpiece, and make test cuts on scrap material to confirm cut quality and adjust feed rate. Replace the blade if you observe excessive chipping, burning, or a significant change in feed resistance.
