IDEAL TCT BLADE [WOOD] [7" X 40T] [25MM BORE] [7" X 40T X 25.4MM] [IGS PRO] CIRCULAR SAW ACCESSORY - 26244

The IDEAL TCT Blade [Wood] features a 25.4mm (1") bore diameter, which is the most common arbor size used across the majority of professional and consumer-grade circular saws. As long as your saw accepts a 180mm (7") blade with a 25.4mm bore, this blade will fit directly. Always verify your saw's maximum blade diameter and arbor size in the tool's manual before purchasing.

Tungsten Carbide Tipped (TCT) blades outperform standard High-Speed Steel (HSS) blades in virtually every wood-cutting metric. TCT teeth are significantly harder, meaning they stay sharper for far longer, generate less heat during cutting, and maintain dimensional accuracy across extended use. While HSS blades may be adequate for occasional light-duty cutting, a TCT blade like this one is the professional standard for anyone cutting regularly or working with hardwoods, engineered boards, or laminated materials.

The IDEAL TCT Blade [Wood] comes complete with the 180mm 40-tooth TCT circular saw blade and a washer set, providing everything needed for immediate, secure installation on your saw. No additional hardware is required for standard mounting.

The 40-tooth TCT configuration is optimized for a wide range of wood-based materials, including softwoods (pine, cedar, spruce), hardwoods (oak, meranti, beech), plywood, MDF, chipboard, and laminated boards. The higher tooth count produces a finer finish cut, making it particularly well-suited for applications where surface quality matters, such as cabinetry, furniture, and interior fit-out work. It is not designed for cutting metal, masonry, or plastic.

This blade is rated for a maximum no-load speed of 8,000 RPM, corresponding to a maximum tip speed of 80 m/s. Never exceed this rated speed. Always ensure your circular saw's maximum RPM does not exceed the blade's rating. Operating a blade beyond its rated speed is a serious safety hazard and can result in blade failure.

Yes. TCT blades can be professionally resharpened by a qualified blade sharpening service, which is one of the key advantages of carbide-tipped blades over disposable steel blades. The number of times a blade can be resharpened depends on the amount of carbide remaining on each tooth. For best results, have the blade resharpened before the teeth become excessively dull, as severely worn carbide tips are more difficult and costly to restore.

Splintering and tear-out are typically caused by one of the following: a dull blade that is no longer cutting cleanly, feeding the material too quickly through the saw, or cutting against the grain without adequate support. With the IDEAL TCT Blade's 40-tooth design, you should achieve a fine finish cut under normal conditions. If splintering persists, check that the blade is sharp, reduce your feed rate, and ensure the workpiece is fully supported to prevent vibration. For laminated surfaces, apply masking tape along the cut line to further minimize tear-out.

Binding and burn marks are usually signs of a dull blade, an incorrect blade for the material, or insufficient saw power for the depth of cut. First, inspect the blade — if the TCT teeth appear worn or chipped, the blade needs resharpening or replacement. Ensure you are not forcing the saw through the material; let the blade do the work at a steady, controlled feed rate. Also verify that the blade is correctly tensioned and that the saw's blade guard and riving knife (if fitted) are properly aligned to prevent the kerf from closing on the blade.

Key indicators that your IDEAL TCT Blade needs resharpening or replacement include: increased cutting resistance requiring more force to push through material, burn marks or scorch lines on the cut surface, visible chipping or rounding of the carbide teeth, excessive vibration during cutting, or a noticeable decline in cut quality and finish. Addressing blade wear early — through professional resharpening — extends the blade's usable life and maintains job-site safety.
