The CMT ITK-Plus Fast Framing Blade is a 5-3/8 in. circular saw blade engineered for rapid, efficient cutting in wood framing, decking, and general construction applications. Built with an Alternate Top Bevel plus Shear (ATB+S) grind at 10 deg. and a 20 deg. cutting angle, this 18-tooth blade is optimized for clean, fast material removal through lumber, plywood, OSB, and hardboard. Designed to fit cordless circular saws and portable table saws with a 10mm bore, it delivers the performance framing professionals and job-site crews depend on when speed and versatility matter most.

Key Features

• 18-tooth ATB+S grind configuration - the Alternate Top Bevel plus Shear geometry at 10 deg. combines aggressive cutting with cleaner edge quality, reducing tear-out on wood, plywood, and OSB compared to a standard flat-top grind
• 20 deg. cutting angle - an aggressive hook angle drives the blade through framing lumber and sheet goods quickly, reducing feed resistance and speeding up repetitive cuts on the job site
• 5-3/8 in. diameter with 10mm bore - sized to fit compact cordless circular saws and portable table saws, making this blade a practical choice for on-site framing work where a full-size saw is impractical
• 0.059 in. kerf thickness - a relatively thin kerf removes less material per pass, conserving battery power on cordless tools and reducing waste in engineered wood panels and sheet goods
• 0.036 in. plate thickness - a slim plate reduces blade flex and drag, contributing to straighter cuts and longer blade life during fast framing applications
• Hard metal (HW) tipped teeth - carbide-tipped tooth construction maintains edge sharpness through the repeated cuts that framing, sheathing, and decking demand, extending time between blade changes
• ITK-Plus classification - CMT's ITK-Plus line is purpose-built for fast framing saw performance, pairing tooth geometry and material with the demands of cordless and portable circular saw platforms

Why This Product

• Framing crews who run cordless circular saws need a blade that cuts fast without draining the battery - the thin 0.059 in. kerf and aggressive 20 deg. cutting angle work together to reduce resistance, preserving charge and cutting time per battery cycle
• The 18-tooth ATB+S grind makes this blade versatile across common job-site sheet goods including plywood, OSB, and hardboard, meaning crews can move from dimensional lumber to sheathing without swapping blades
• At 5-3/8 in. diameter with a 10mm bore, this blade is matched specifically to the compact cordless circular saw and portable table saw format - it is not a compromise fit but a purpose-designed pairing for these machine types
• Hard metal (HW) tipped teeth are designed to hold their edge through the high-volume repetitive cuts that framing and decking generate, reducing downtime spent on blade changes during critical phases of a project

Frequently Asked Questions

What type of grind does this blade use and why does it matter?

This blade uses a 10 ATB+S grind - Alternate Top Bevel plus Shear at 10 deg. This geometry alternates the bevel angle on successive teeth while adding a shear component, which improves cut quality on wood, plywood, OSB, and hardboard by reducing tear-out compared to a basic flat-top grind, without sacrificing the cutting speed needed for fast framing work.

What machines is this blade compatible with?

This blade is designed for cordless circular saws and portable table saws. It has a 5-3/8 in. diameter and a 10mm bore. Blade diameter compatibility is contingent on machine type, so confirm your saw accepts a 5-3/8 in. blade with a 10mm arbor before installing.

What is the maximum RPM rating for this blade?

The CMT ITK-Plus Fast Framing Blade is rated for a maximum of 11,300 RPM. Always verify that your saw's no-load RPM does not exceed this rating before use to ensure safe operation.

Why does the kerf thickness matter on a cordless circular saw?

The kerf thickness on this blade is 0.059 in. A thinner kerf removes less material with each pass, which directly reduces the load placed on the motor and battery of a cordless circular saw. Less resistance per cut means the battery can sustain more cuts per charge, which is a practical advantage during extended framing sessions on the job site.
