The Diablo 8-1/4" x 40-Teeth Finishing Saw Blade for Wood is engineered for smooth, professional-quality finish crosscuts in hardwood, softwood, and plywood. Designed by Diablo for use with circular saws, cordless circular saws, and both stationary and portable table saws, this 40-tooth ATB blade delivers the cleaner, smoother edges that finish carpentry demands - without sacrificing the cutting speed and long service life you need on the jobsite. Whether you are working with decking, fencing, fascia, 1X boards, or sheet goods like plywood and OSB, this blade provides an excellent combination of performance and durability that sets it apart from standard framing blades.

Key Features

• TiCo Hi-Density carbide - specifically formulated for finish wood cutting applications, delivering enhanced performance and longer-lasting sharpness compared to standard carbide tips
• Perma-SHIELD Non-stick Coating - protects the blade body from heat, gumming, and corrosion, which extends blade life and helps maintain clean, consistent cuts over time
• Super thin laser cut kerf at.094" - removes less material per pass for faster cuts, reduced waste, and cleaner finished edges in hardwood, softwood, and sheet goods
• Tri-metal shock resistant brazing - bonds carbide tips with exceptional strength so they withstand extreme impact, reducing the risk of tip loss and extending overall blade durability
• Hardened steel body - provides a longer service life and supports a sharper, more consistent cutting edge across a wide range of wood materials
• 40 ATB (Alternate Top Bevel) tooth geometry - the configuration preferred for finish cuts, producing smooth edges that require less sanding or cleanup on hardwoods, laminated beams, and pressure-treated lumber
• 15 deg. hook angle - optimized for finish crosscutting, helping to reduce splintering and deliver clean results on plywood and solid wood alike

Why This Product

• Ideal upgrade from a framing blade - the 40-tooth ATB design and thin.094" kerf deliver a noticeably smoother cut on decking, fascia, and fencing where surface appearance matters
• Compatible with a wide range of tools - fits circular saws, cordless circular saws, stationary table saws, and portable table saws with a standard 5/8" arbor, making it a versatile choice for contractors and finish carpenters
• Built for jobsite durability - the Perma-SHIELD Non-stick Coating and Tri-metal shock resistant brazing protect the blade from heat buildup and impact, reducing downtime and replacement costs on demanding job sites
• Cuts a broad range of materials - rated for plywood, 2X lumber, pressure-treated wood, OSB, hardwoods, and laminated beams, covering the full range of materials common in finish carpentry and exterior trim work

Frequently Asked Questions

What types of wood can this Diablo blade cut?

This blade is designed for use with plywood, 2X lumber, pressure-treated wood, OSB, hardwoods, and laminated beams. It is specifically suited for smooth finish crosscuts in hardwood, softwood, or plywood, including jobsite applications like decking, fencing, fascia, and 1X boards.

What tools is this 8-1/4" blade compatible with?

This blade is compatible with circular saws, cordless circular saws, stationary table saws, and portable table saws. It uses a standard 5/8" arbor and has a maximum rated speed of 8000 RPM.

How does this finishing blade differ from a standard framing blade?

This Diablo finishing blade features 40 ATB (Alternate Top Bevel) teeth and a 15 deg. hook angle, which together produce a smoother cut edge than typical framing blades. The result is cleaner, finish-quality cuts on wood surfaces where appearance matters, while still offering excellent cutting speed and long blade life.

What is the kerf width of this blade, and why does it matter?

The kerf is.094", which is a super thin laser cut kerf. A thinner kerf removes less material per pass, resulting in faster cuts, less waste, and cleaner finished edges - especially important when working with hardwoods, plywood, and other finish materials where precision is critical.
