Diablo 6" x 40-Tooth Finish Saw Blade for Porter Cable Saw Boss is a thin kerf trim saw blade engineered by Diablo for smooth, splinter-free crosscuts in hardwood, softwood, and plywood. Designed specifically for portable and low-powered trim saws, this finish cutting blade extends battery and motor run time on Porter Cable Saw Boss and similar compact saws - making it an ideal choice for finish carpentry, trim work, and precision panel cutting on the jobsite. Manufactured in Italy with Diablo's TiCo Hi-Density Carbide technology, this 40-tooth ATB blade delivers clean, accurate results in demanding materials including laminate, melamine, OSB, and pressure treated lumber.

Key Features

• TiCo Hi-Density Carbide specifically designed for each application to provide maximum performance and cutting life - meaning the carbide formulation is matched to finish cutting demands, so the blade stays sharper longer and delivers consistent results through hardwoods, plywood, and engineered sheet goods
• Super thin laser cut kerf gives extremely fast, durable, and clean cuts - the.049" kerf removes less material per pass, reducing load on low-powered trim saws and producing smoother finished edges with less tearout
• Laser-cut stabilizer vents trap noise and vibration keeping the blade cool and reducing blade warp - cooler running means longer blade life and a steadier cut, especially during extended trim saw sessions on the jobsite
• Non-stick Perma-Shield Coating reduces gumming, rusting, and corrosion - keeps the blade surface clean when cutting resinous woods, pressure treated lumber, and adhesive-backed laminates so the blade glides freely and lasts longer between cleanings
• Laser cut arbor for accurate blade rotation reducing vibration and premature wear - precise arbor geometry means the blade tracks true on the saw spindle, producing straighter cuts and protecting both the blade and the saw over time
• 18 deg. hook angle optimized for finish crosscutting - this moderate positive hook angle balances feed rate and surface quality, helping produce clean, chip-free edges in hardwood and plywood face veneers
• Maximum 12,000 RPM rating - compatible with the full operating speed range of Porter Cable Saw Boss and similar high-speed trim saws, so you never have to derate or limit your tool's performance

Why This Product

• Purpose-built for trim saws - the thin.049" kerf and 40-tooth ATB geometry are specifically matched to the lower motor power of Porter Cable Saw Boss and similar compact saws, reducing drag and extending runtime compared to standard circular saw blades
• Handles the widest range of finish materials on the jobsite - hardwoods, 2X lumber, laminate, melamine, plywood, OSB, and pressure treated lumber are all listed as approved materials, so one blade covers the full scope of typical finish carpentry and trim installation work
• Diablo's Perma-Shield Coating and TiCo Carbide combine to reduce downtime from blade cleaning and resharpening - the non-stick surface sheds resin and adhesive buildup while the premium carbide holds an edge through demanding cuts, keeping your work moving
• Laser-cut stabilizer vents and precision arbor geometry address the two most common sources of blade failure in portable saws - heat warping and vibration-induced wear - making this blade a dependable, long-lasting choice for finish cutting applications

Frequently Asked Questions

What saws is this blade compatible with?

This Diablo 6" finish saw blade is designed for trim saws, and is proven to extend run time on Porter Cable Saw Boss and similar trim saw models. The 1/2" arbor and 6" diameter are matched to the spindle and blade guard dimensions typical of these compact portable saws.

What does the ATB tooth grind mean for finish cutting results?

ATB stands for Alternate Top Bevel - a grind pattern where teeth alternate between left and right bevel angles. This geometry slices wood fibers cleanly on both sides of the cut, reducing tearout and splintering on the face of hardwoods, plywood veneers, laminate, and melamine for a smooth finished edge.

What is the difference between the kerf and the plate thickness on this blade?

The kerf (.049") is the total width of material removed by the blade as it cuts, while the plate thickness (.039") is the thickness of the steel body of the blade itself. The difference between the two is the carbide tooth overhang on each side, which allows the plate to pass through the cut without binding against the workpiece.

Can this blade cut pressure treated lumber and engineered panels?

Yes. Pressure treated lumber, OSB, plywood, laminate, and melamine are all listed as compatible materials for this blade. The Perma-Shield Coating helps resist corrosion from the chemicals in pressure treated wood, and the TiCo Hi-Density Carbide provides the cutting life needed for abrasive engineered panel materials.
