The Diablo 6-1/2" x 40-Tooth Finish Trim Saw Blade is a premium wood cutting blade engineered for smooth, clean crosscuts in hardwood, softwood, and plywood. Crafted in Italy and built around Diablo's TiCo Hi-Density Carbide technology, this 6-1/2" circular saw blade delivers the refined edge quality that finish carpenters and trim installers demand - without sacrificing cutting speed or blade longevity. Whether you're making precision cuts in laminate, melamine, pressure treated lumber, or OSB, this 40-tooth ATB blade brings professional-grade finish cutting performance to both corded and cordless circular saws.

Key Features

• TiCo Hi-Density Carbide teeth (40 ATB) - carbide is specifically formulated for finish cutting applications, delivering maximum sharpness retention and longer cutting life across hardwoods, softwoods, laminate, and plywood
• Super thin.059" laser-cut kerf - removes less material per pass, resulting in faster, cleaner cuts with less strain on cordless circular saws and trim saws
• Laser-cut stabilizer vents - trap noise and vibration during cutting, keeping the blade cooler and reducing the risk of blade warp during extended use
• Non-stick Perma-Shield Coating - protects the blade plate from gumming, rusting, and corrosion, extending overall service life and keeping cuts smooth even in resinous or treated lumber
• 15 deg. hook angle - optimized geometry for smooth, controlled finish crosscuts that minimize tearout in hardwoods, plywood, and melamine
• Ultra-thin.039" plate with laser-cut precision - ensures true, accurate cuts with minimal deviation, critical for trim and finish carpentry work
• 5/8" arbor with diamond knockout - compatible with a wide range of 6-1/2" trim saws, corded circular saws, and cordless circular saws for maximum tool versatility
• 10,000 Maximum RPM rating - engineered to perform safely at the speeds typical of compact trim and circular saws used on the jobsite

Why This Product

• Designed specifically for finish cutting - the 40-tooth ATB configuration and 15 deg. hook angle work together to produce smoother edges than standard framing blades, making this blade the right choice when cut quality matters on visible trim, fascia, decking, and plywood panels
• Built for versatility across tough materials - rated for hardwoods, 2X lumber, laminate, melamine, plywood, OSB, and pressure treated wood, this blade handles the full range of materials encountered in finish carpentry and renovation work
• Thin kerf design reduces battery and motor demand - the.059" kerf means less resistance per cut, which translates directly into more cuts per battery charge when used with cordless circular saws on the jobsite
• Laser-cut stabilizer vents and Perma-Shield Coating address two of the most common blade failure points - heat-related warp and corrosion - helping maintain cut quality and extend the usable life of the blade in real-world jobsite conditions

Frequently Asked Questions

What types of saws is this 6-1/2" blade compatible with?

This blade is compatible with trim saws, corded circular saws, and cordless circular saws equipped with a 5/8" arbor. The blade is rated to a maximum of 10,000 RPM, which aligns with the operating speeds of most compact 6-1/2" saws in these categories.

What materials can this blade cut?

This blade is designed to cut hardwoods, 2X lumber, laminate, melamine, plywood, OSB, and pressure treated wood. It is specifically optimized for smooth finish crosscuts in hardwood, softwood, and plywood where cut quality is a priority.

Why does the thin kerf matter for cordless circular saw users?

The.059" laser-cut kerf removes less material per pass compared to thicker standard kerfs. This reduces the cutting resistance the motor must overcome, which means less battery drain per cut - an important advantage when working with cordless circular saws on jobsites where runtime matters.

How does the 40-tooth ATB configuration differ from a framing blade?

The 40-tooth Alternate Top Bevel (ATB) tooth geometry is designed to shear wood fibers cleanly, producing smoother edges suitable for finish carpentry applications such as trim, fascia, decking, fencing, and plywood panels. Framing blades typically use fewer teeth optimized for speed rather than surface finish quality.
