The Diablo 14" Diamond Segmented Blade for Asphalt is a premium wet-cutting diamond blade engineered for demanding asphalt cutting applications in roadwork, construction, and demolition environments. Built around a hardened disc body with taller laser welded segments and an expertly balanced premium steel core, this blade delivers up to 3x the cutting life of standard asphalt blades - reducing downtime and increasing jobsite productivity. Compatible with gas saws, masonry chop saws, and walk-behind saws, this Diablo blade is purpose-built for contractors who need consistent, clean cuts through asphalt, concrete, and green concrete under high-speed conditions.

Key Features

• Up to 3x longer cutting life than standard asphalt blades - fewer blade changes mean less downtime and lower cost per cut on large-scale pavement or roadwork projects.
• Taller laser welded segments with superior quality diamonds and an ultra-durable bond to the disc body - delivers faster cuts and extended cutting life even in the most abrasive materials.
• Hardened disc body absorbs vibration and increases impact resistance - produces superior quality cuts in asphalt, concrete, and green concrete without premature fatigue or deflection.
• Optimized laser welded diamond segments and diamond distribution ensure constant diamond exposure - maximizes performance during high-speed cutting applications for consistently clean results.
• Expertly balanced premium steel core reduces vibration and noise - improves operator comfort and blade tracking accuracy throughout extended use.
• Undercut protection prevents premature wear of the steel body and loss of diamond segments - safeguards the blade investment and maintains cutting efficiency over the full service life.
• Includes a 1" arbor with a pre-set 20mm bushing - provides broad arbor compatibility without requiring additional adapters for most saw configurations.
• Designed for wet cutting - water cooling extends segment life and reduces heat buildup, keeping cuts cleaner and the blade running longer in continuous operations.
• Maximum RPM of 5,500 - rated for the high-speed demands of gas saws and walk-behind saws used in heavy-duty pavement cutting.

Why This Product

• Contractors cutting asphalt on roadwork or demolition sites need a blade that holds up under repeated, continuous passes - this blade's up to 3x longer cutting life directly reduces replacement frequency and keeps jobs on schedule.
• The segmented rim design enhances cooling and debris removal during wet cutting operations, making it a reliable choice for long cuts through thick pavement where heat buildup would otherwise shorten blade life.
• Undercut protection is a critical safeguard on abrasive materials like asphalt and green concrete - it prevents the steel core from wearing faster than the segments, preserving diamond retention and overall blade integrity throughout the job.
• With compatibility across gas saws, masonry chop saws, and walk-behind saws - and a 1" arbor with a pre-set 20mm bushing included - this blade fits a wide range of equipment already on the jobsite without additional hardware.

Frequently Asked Questions

Is this blade designed for wet or dry cutting?

This blade is designed for wet cutting. Using water during the cut helps cool the segments, removes debris from the kerf, and extends the service life of the diamond segments - particularly important during extended cuts through dense asphalt or concrete.

What saws are compatible with this blade?

This blade is compatible with gas saws, masonry chop saws, and walk-behind saws. It includes a 1" arbor with a pre-set 20mm bushing to accommodate a range of saw spindle sizes without requiring separate adapters.

What is the maximum operating speed for this blade?

The maximum rated speed is 5,500 RPM. Always verify that the saw being used does not exceed this limit before operating, as running a blade beyond its rated RPM presents a serious safety risk.

What does undercut protection mean, and why does it matter?

Undercut protection refers to a design feature that prevents the steel disc body from wearing down faster than the diamond segments. Without this protection, the body can become undercut by abrasive material, causing segment loss and premature blade failure. On abrasive materials like asphalt and green concrete, this feature is especially important for maintaining safe operation and extending the usable life of the blade.
