Precision-Ground. Carbide-Tough. Built to Cut More, Replace Less.
The IDEAL TCT Circular Saw Blade is a professional-grade Tungsten Carbide Tipped (TCT) wood cutting blade engineered for precision, durability, and consistent performance. Featuring a 180mm (7") diameter with 12 carbide-tipped teeth and a 25.4mm bore, this blade delivers clean, splinter-free cuts at speeds up to 8,000 RPM. Built on an aluminium alloy body, it combines lightweight handling with the rigidity needed for demanding woodworking tasks, making it the ideal accessory for the IDEAL IGS PRO circular saw system.

- TCT Tooth Technology for Superior Edge Retention: Each of the 12 teeth is tipped with Tungsten Carbide, one of the hardest cutting materials available. This ensures the blade maintains a razor-sharp cutting edge through extended use on hardwoods, softwoods, plywood, and MDF, significantly outlasting standard high-speed steel (HSS) blades and reducing the frequency and cost of blade replacement.
- Optimised 12-Tooth Geometry for Wood Applications: The 12-tooth (12T) configuration is specifically engineered for wood cutting, striking the ideal balance between cutting speed and surface finish quality. Fewer teeth mean larger gullets, which efficiently evacuate sawdust and chips, preventing clogging and overheating during continuous cuts, critical for maintaining blade integrity and motor health on your circular saw.
- 180mm Diameter with 25.4mm Bore — Broad Compatibility: The 7-inch (180mm) blade diameter is a widely used standard in professional circular saws, providing a generous cutting depth suitable for structural timber and sheet goods. The 25.4mm (1") bore size fits the majority of standard circular saw arbors, and the included washer set ensures a secure, wobble-free mount for accurate, safe operation.
- High-Speed Rated at 8,000 RPM / 80 m/s: Rated for a maximum no-load speed of 8,000 RPM (equivalent to a peripheral cutting speed of 80 m/s), this blade is engineered to handle the full power output of professional circular saws without risk of structural failure. The high-speed rating ensures compatibility with variable-speed tools and guarantees safe operation at peak machine performance.
- Aluminium Alloy Plate Body — Lightweight Rigidity: The blade plate is manufactured from precision-stamped aluminium alloy, chosen for its exceptional strength-to-weight ratio. The lightweight body reduces rotational inertia for faster spin-up and spin-down, while the inherent rigidity of the alloy minimises blade flex and lateral deflection during cuts — a key factor in achieving straight, accurate kerfs. The aluminium construction also dissipates heat more effectively than steel, extending both blade and tooth life. The blade ships complete with a washer set to ensure correct fitment and clamping force on your saw's arbor flange.
General Purchase & Comparison Queries
Is this blade compatible with my circular saw?
This blade is designed with a 25.4mm (1") bore and a 180mm (7") diameter, which are standard dimensions compatible with the majority of professional circular saws — including the IDEAL IGS PRO system. Always verify your saw's arbor size and maximum blade diameter rating before fitting. The included washer set assists with correct arbor fitment on compatible machines.
How does a TCT blade compare to a standard HSS blade for wood cutting?
Tungsten Carbide Tipped (TCT) blades significantly outperform standard High-Speed Steel (HSS) blades in both longevity and cut quality. TCT teeth are brazed onto the blade body and are far harder than HSS, meaning they stay sharp through many more cutting cycles — especially in abrasive materials like hardwood, plywood, and MDF. While HSS blades are cheaper upfront, TCT blades offer a lower cost-per-cut over their lifespan, making them the preferred choice for professional and frequent use.
Why choose a 12-tooth blade over a higher tooth-count blade?
Tooth count directly affects the trade-off between cutting speed and surface finish. A 12-tooth (12T) blade is optimised for fast, aggressive cuts through solid timber and structural lumber — the large gullets between teeth efficiently clear sawdust, preventing heat build-up and blade binding. Higher tooth-count blades (e.g., 40T–60T) produce finer finishes but cut more slowly and are better suited for fine joinery or sheet materials where surface quality is the priority. For general construction, framing, and site work, a 12T blade is the practical, high-efficiency choice.
Product-Specific and Usage Queries
What types of wood can this blade cut?
This TCT Wood Blade is suitable for cutting a wide range of wood-based materials, including softwoods (pine, spruce, fir), hardwoods (oak, beech, meranti), plywood, OSB (oriented strand board), chipboard, and engineered timber panels. It is not intended for cutting metal, masonry, or plastics. Always ensure the material is securely clamped and supported before cutting.
What is the maximum safe operating speed for this blade?
The blade is rated for a maximum no-load speed of 8,000 RPM, which corresponds to a peripheral cutting speed of 80 m/s. Never exceed this speed rating. Always check your circular saw's no-load RPM specification and ensure it does not exceed the blade's maximum rated speed. Operating above the rated speed risks blade failure, which is a serious safety hazard.
How do I correctly mount this blade on my circular saw?
Ensure your saw is fully powered off and unplugged before changing blades. Fit the blade onto the arbor with the tooth direction matching the saw's rotation arrow (typically forward-facing at the bottom of the blade). Use the included washer set as directed by your saw's manual to ensure correct clamping. Tighten the arbor nut securely — most saws use a left-hand thread on the arbor nut, so tighten clockwise when viewed from the blade face. Confirm the blade is seated flat and wobble-free before operating.
Problem/Solution-Oriented Queries
My blade is leaving a rough, splintered cut — what should I do?
A rough or splintered cut is typically caused by one of three issues: a dull or damaged blade, incorrect feed rate, or cutting against the grain without adequate support. First, inspect the TCT teeth for chips or excessive wear — a worn blade should be replaced or professionally resharpened. Second, ensure you are feeding the material at a steady, controlled pace — forcing the blade causes deflection and tear-out. For fine finishes on plywood or veneered panels, consider using a higher tooth-count blade better suited to finish cutting.
The blade is overheating during use — what could be causing this?
Blade overheating is most commonly caused by sawdust build-up in the gullets, a blunt cutting edge, or cutting at too slow a feed rate (which causes the blade to rub rather than cut). Ensure the blade is clean and free of resin or pitch build-up — use a dedicated blade cleaner if needed. Check that the blade is sharp; TCT teeth can be professionally resharpened. Also verify that your saw is operating at the correct RPM for the material thickness and that the blade depth is set correctly — exposing only slightly more than the material thickness reduces friction and heat.
The blade does not fit my saw's arbor — what are my options?
This blade has a 25.4mm (1") bore. If your saw has a smaller arbor (e.g., 20mm or 16mm), you can use a reduction ring (arbor reducer bushing) to adapt the bore to your saw's arbor size — these are widely available from tool accessory suppliers. Never attempt to force a blade onto an undersized arbor or modify the bore, as this compromises blade integrity and is a safety risk. If your saw requires a larger bore than 25.4mm, this blade is not compatible and an alternative blade specification should be sourced.
