The CMT ITK Contractor Saw Blade for Framing and Decking is an 8-1/4 in. circular saw blade engineered for professionals who demand fast, reliable cuts in wood framing, deck construction, and structural panel work. Featuring a 24-tooth Alternate Top Bevel (ATB) grind at 10 deg. and a 20 deg. hook angle, this hardwood-carbide-tipped blade is purpose-built for ripping hardwood, softwood, plywood, and OSB on cordless circular saws and portable table saws. Its laser-cut steel plate and polymer-filled sound-dampening slots combine precision and control on the job site, making it a go-to choice for contractors handling demanding framing and decking applications.

Key Features

• 24-Tooth ATB 10 deg. Grind - the Alternate Top Bevel geometry at 10 deg. sharpening delivers fast, aggressive cuts through framing lumber and structural panels, reducing blade drag and improving cut efficiency.
• 20 deg. Hook Angle - an assertive hook angle promotes quick material feed and smooth stock removal, ideal for the fast-paced demands of framing and deck board installation.
• Hardwood Carbide Tips (HW Material Grade) - carbide-tipped teeth maintain a sharp cutting edge longer than standard steel teeth, extending blade life through repeated cuts in hardwood, softwood, plywood, and OSB.
• 0.071 in. Kerf Thickness - a full-kerf design provides a stable, vibration-resistant cut path that keeps the blade tracking straight through dense lumber and engineered panels.
• 0.047 in. Plate Thickness - a thinner plate reduces the material removed per pass, requiring less motor effort from cordless circular saws and helping preserve battery runtime on the job.
• Laser-Cut Steel Plate - precision laser cutting holds tight tolerances on the blade body, producing consistent, accurate cuts and minimizing blade wobble during use.
• Polymer-Filled Sound-Dampening Slots - laser-cut slots filled with polymer compound absorb vibration and reduce operational noise, lowering user fatigue during extended cutting sessions.
• Orange Chrome Coating - a chromium layer electrolytically deposited on the blade body increases wear resistance, protects against corrosion, and extends overall blade service life.
• Tri-Metal Silver Brazing (Silver-Copper-Silver) - this three-layer brazing method bonds carbide tips to the plate with exceptional strength, preventing carbide from breaking or separating under high-stress cutting loads.
• 5/8 in. Bore Diameter - a standard 5/8 in. arbor bore fits a wide range of cordless circular saws and portable table saws, making installation quick and straightforward without adapters.

Why This Product

• Designed specifically for cordless circular saws and portable table saws, this blade's 0.047 in. plate thickness reduces motor load - a direct advantage when running battery-powered tools where power efficiency matters on every cut.
• With 24 ATB teeth at a 20 deg. hook angle, the blade is optimized for the fast ripping passes required in framing and decking work - cutting hardwood, softwood, plywood, and OSB without requiring repeated passes or excessive downward pressure.
• The combination of orange chrome coating and tri-metal silver brazing addresses two common blade failure points - corrosion on the plate and carbide tip separation - helping the blade hold up through rough job-site conditions and heavy use cycles.
• At 8-1/4 in. diameter with a 5/8 in. bore, this blade fits standard cordless circular saw platforms, giving contractors a direct-fit framing and decking solution without the need for special adapters or machine modifications.

Frequently Asked Questions

What saws is this blade compatible with?

This blade is designed for use with cordless circular saws and portable table saws that accept an 8-1/4 in. blade with a 5/8 in. arbor bore. No adapter is needed for saws with a standard 5/8 in. arbor.

What materials can this blade cut?

The CMT ITK Contractor Framing and Decking blade is suitable for ripping hardwood, softwood, plywood, and OSB. Its 24-tooth ATB grind and 20 deg. hook angle are configured for fast stock removal in these structural and engineered wood materials.

What is the maximum RPM rating for this blade?

This blade is rated for a maximum of 9,000 RPM. Always confirm your saw's no-load RPM does not exceed this rating before use to ensure safe operation.

Why does the blade have polymer-filled slots?

The laser-cut slots in the blade plate are filled with a polymer compound that absorbs vibration during cutting. This reduces operational noise and minimizes hand and arm fatigue during extended framing or decking work sessions.
