The CMT ITK-Plus Finish Saw Blade - 8-1/4 x 40 x 5/8 inch is a professional-grade circular saw blade engineered for fine finish cutting in wood, plywood, OSB, and hardboard. Designed specifically for cordless circular saws and portable table saws, this 40-tooth blade delivers clean, smooth results in demanding finish carpentry and cabinetry applications. The Alternate Top Bevel (ATB) tooth geometry at 15 deg. sharpening, combined with a 10 deg. hook angle, produces precise crosscuts and rip cuts with minimal tear-out - making it the go-to choice for woodworkers who need reliable finish-quality performance from a portable or job-site setup.

Key Features

• ATB 15 deg. Tooth Grind - the Alternate Top Bevel geometry at 15 deg. sharpening slices cleanly through wood fibers, reducing splintering and leaving smooth, finish-ready edges on hardwood, plywood, OSB, and hardboard.
• 40-Tooth Configuration - a higher tooth count compared to ripping blades means finer chip load per tooth, translating to cleaner cut surfaces that require less sanding and finishing work.
• 10 deg. Hook Angle - the positive hook angle keeps feed rate controlled and predictable, helping operators maintain accuracy during both crosscuts and rip cuts on finish materials.
• 0.094 inch Kerf with 0.063 inch Plate - the kerf-to-plate ratio provides blade stability during the cut while keeping material waste to a minimum, which matters when working with premium sheet goods or hardwoods.
• 5/8 inch Bore with Knock-Out Pin Hole - the standard 5/8 inch arbor bore fits the widest range of cordless circular saws and portable table saws, while the knock-out pin hole adds compatibility flexibility across different machine configurations.
• 9,000 RPM Maximum Speed Rating - rated for up to 9,000 RPM, this blade can safely keep pace with high-speed cordless saws, ensuring efficient cutting performance without exceeding safe operating limits.
• Hard Metal (HW) Tooth Material - carbide-grade tooth construction stays sharp through extended use on engineered wood products and hardboards, reducing the frequency of blade changes on the job site.
• Dual Diameter Designation (8 inch / 8-1/4 inch) - compatible with both 8 inch and 8-1/4 inch saw formats, giving this blade broader machine compatibility across job-site circular saws and portable table saws.

Why This Product

• If your cordless circular saw or portable table saw demands a finish-quality blade that keeps up at 9,000 RPM, this ITK-Plus is rated for exactly that speed - avoiding the safety risk of under-rated blades on high-RPM cordless tools.
• The 40-tooth ATB 15 deg. geometry is purpose-built for finish cuts in wood, plywood, OSB, and hardboard - meaning fewer secondary finishing steps and cleaner results straight off the saw.
• The 5/8 inch bore with a knock-out pin hole makes this blade compatible across a wider range of machines, reducing the need to stock multiple blade sizes for different saws on the job site.
• The thin 0.063 inch plate keeps the blade light and maneuverable in portable applications, while the 0.094 inch kerf provides enough tooth support for stable, accurate cutting through sheet goods and dimensional lumber.
