Diamond saw blades used with joint cleanout and crack chasing saws vary in diameter, width and matrix depending on their specific uses
No one diamond saw blade fits all scenarios. There are many types of dry cut diamond blades in the marketplace varying widely in composition and quality. Blades that are well suited for standard joint cleanout may not be the ideal choice for removing existing fillers. Here are a few important considerations when selecting a diamond blade for your joint cleanout saw or crack chasing saw:
- Blade width – blade should be wide enough to encapsulate both joint walls when cleaning or repairing joints or if blade is narrower saw must be run up both sides of joint to provide proper edge cleaning/restoration.
- Blade diameter – blade diameter should be large enough to reach the bottom of the sawn joint when cleaning joints to allow for proper installation of semi-rigid joint fillers. In the case of construction or “cold” joints blade will need to reach a depth of 2”
- Blade quality – when looking at diamond blades it’s important to look at the quality and the expected life of the blade rather than simply looking at cost. A $100 blade which is expected to last 5,000 lineal feet is better than a $20 blade that lasts 500 feet.
- Metzger/McGuire and our distribution partners carry a wide variety of blades to address the multiple needs on any given project – from standard joint cleanout blades to Stellite blades designed for existing filler removal and “u” shaped crack chasing blades.
Below is a list of blades which we have tested and which our customers have reported good success with on past projects. We invite to contact our technical service team to discuss your equipment and saw blades needs.
