Circular saw blade NORTON 330 mm x 30 mm, 40 teeth, for wood and composites, ATB (3.2/2.2)

NORTON circular saw blade 330 mm x 30 mm with 40 ATB teeth is designed for cutting wood and composite materials. The blade has a 330 mm diameter and a 30 mm bore, with alternating top bevel (ATB) tooth geometry that provides clean edges on crosscuts and satisfactory performance on rip cuts. The blade thicknesses are 3.2 mm at the outside and 2.2 mm at the inside, offering a balance between rigidity and reduced kerf for efficient material removal. It is intended for use on table saws and mitre saws configured for a 330 mm blade with a 30 mm arbor.

Advantages

The ATB tooth geometry creates fine, clean cuts in wood and laminate surfaces, reducing splintering on edges. The 40-tooth count offers a compromise between cutting speed and finish quality, suitable for both crosscutting and general-purpose woodworking. The combination of outer and inner thicknesses improves blade stability while keeping the kerf moderate, which helps maintain material yield and reduces waste. Compatibility with common 30 mm arbors ensures straightforward mounting on compatible machines.

Suitable for

• Crosscutting solid wood and laminated boards
• Ripping and general-purpose cuts on soft and hardwoods
• Cutting composite panels, laminates and MDF
• Use on table saws and mitre saws with 330 mm / 30 mm blade requirements

How to use

Install the blade on a table saw or mitre saw that accepts a 330 mm diameter blade with a 30 mm arbor. Ensure the saw is disconnected from power before mounting. Fit the blade so that the ATB teeth face the correct cutting direction as indicated by the saw manufacturer. Tighten the arbor nut to the recommended torque and check blade runout and alignment before use. When cutting, adjust feed rate and blade height according to material thickness and desired finish; use push sticks and guards for safety. Regularly inspect the blade for wear, chipping or buildup and clean or replace it when cutting quality declines.

Usage recommendations

For best results on laminated panels and veneered boards, use a slower feed rate and support the workpiece to minimize tear-out. Keep the blade clean from resin and adhesive buildup and perform professional sharpening when teeth become dull to restore cutting quality and prolong blade life.
