Saw Blades

The Best Blade for the Job

By Jennifer Morrell

Saw blade technology continues to provide end-users with the utmost in cost-effective use, efficiency and a long life of the blade. Not only are the blades boasting best-in-class design, but also companies are becoming more consumer oriented than ever – particularly regarding packaging. No more confusion when selecting the appropriate blade for the material at hand. Labeling is clear and concise, with some packaging concepts using an image of the material (bricks, concrete, etc.) right on the packaging and on the blade itself. Masonry has gathered a sampling of some of the latest and greatest saw blades available for the choosing. No matter your need, there’s a blade for your job.

Sandwich Tuckpointing Diamond BladeBosch Mount Prospect, Ill. Sandwich Tuckpointing Diamond Blade Every brick or stone building in North America will meet the tuckpointer at some point to cut, clean and repair old mortar. Deteriorating mortar leads to water seepage, which can ruin the structural integrity of a building. This critical application demands high-quality, long-lasting diamond tuckpointing blades that can withstand a harsh environment. By combining tall segments and a superior diamond/metal mix with an efficient and fast sandwich blade design, Bosch has created long-lasting tuckpointing blades that are designed to grind more surface area than competitive blades. The addition of 4.5-inch and 5-inch diameter sandwich blades gives the company a broad offering for use in hand-held grinders. The eight-segment blades are made exclusively for dry tuckpointing applications. Blade widths are 6.35 mm (?? inch) with cutting depths ranging from .75 inch for 4.5-inch blades to 1.25 inch for 5-inch blades. Typical applications for tuckpointing blades include mortar removal in brick buildings and grout removal in commercial tile applications. Bosch combines copper, iron, nickel and cobalt hard-bond metal powders with high-grade diamonds to create hardened 10-mm segments. These blades have high-diamond content to cut mortar efficiently and ample keyhole gullets to remove discarded cement and other debris. www.boschtools.com Precision Framing BladeDEWALT Baltimore, Md.

Torrence, Calif. MK-742D Dry Cutting Diamond Blade MK Diamond Products’ MK-742D dry cutting diamond blade is a high-speed blade that has been engineered using an arrayed pattern of diamonds. The diamonds are effectively aligned so that each diamond is working in unison for maximum abrasion and material removal. The arrayed pattern allows all the diamonds to work in unison, increasing cutting efficiency by 65 percent over conventional blades. The MK-742DSL Silent Core also uses the arrayed diamond pattern, but with the benefit of a Sandwich Core. The Sandwich Core is manufactured with two steel cores laminated with a copper center that provides the greatest sound reduction. This is beneficial on jobsites, where controlling the cutting noise level is an issue near schools, hospitals or residential areas. In addition, a quieter blade reduces the chance of hearing loss for an operator. The silent core also reduces vibration, which is beneficial to the operator’s safety and adds longevity to the blade life. Both blades contain only the highest quality synthetic diamonds and have a 10-mm segment height. The wide gullet design provides exceptional cooling. The blades are available in 14-inch diameters. www.mkdiamond.com 4X4 Diamond BladeNorton Worchester, Mass. 4X4 Diamond Blade Labor is the largest cost for any contractor.
