CMT circular saw blade set 250 x 30 mm, 24/40 teeth, HM, two blades

Set of two CMT circular saw blades, each 250 x 30 mm, designed for woodworking machines with a 30 mm bore. The pair includes a 24-tooth blade for faster, coarser ripping and a 40-tooth blade for finer crosscuts and smoother finish cuts. Both blades feature carbide (HM) tipped teeth for improved edge life and consistent cutting performance on a variety of wood materials.

Advantages

The blades combine carbide-tipped teeth with a 250 mm diameter to deliver durable cutting edges and reliable performance. Having two tooth-count options in one set allows rapid adjustment between faster material removal and cleaner finish cuts without changing the machine or investing in separate full-size blades. The 30 mm bore fits standard woodworking saw arbors designed for this diameter, enabling stable mounting and reduced vibration during operation.

Suitable for

• Rip cutting of solid wood and panel materials where faster feed is required
• Crosscutting and finish cuts that require a smoother edge and reduced tear-out
• Workshops and hobbyist setups using machines with a 30 mm arbor
• General-purpose woodworking tasks where both coarse and fine tooth options are useful

Key specifications

• Diameter: 250 mm
• Bore (arbor) diameter: 30 mm
• Teeth: set contains 24T and 40T configurations
• Tooth material: carbide (HM) tipped
• Quantity: 2 blades per set

How to use

Select the blade with the appropriate tooth count for your intended cut: the 24-tooth blade for faster rip cuts and the 40-tooth blade for smoother crosscuts or finishing operations. Ensure the saw is unplugged or the power is off, then mount the blade securely on a compatible 30 mm arbor, following the machine manufacturer's instructions for correct flange orientation and torque. Verify blade concentricity and clearance, set the correct cutting speed and feed rate for the material, and use appropriate guards and push devices. After use, inspect the teeth for wear or damage and replace the blade if chips or significant dulling are present.

Usage recommendations

Use the 24T blade for dimensioning and fast ripping of solid timber and laminated panels; switch to the 40T blade when making crosscuts or when a cleaner edge is required. Maintain proper feed rates, avoid excessive side pressure, and keep blades clean from pitch and resin to extend carbide life. For consistent results, match blade selection to material type and thickness and follow machine safety guidelines.
