Dewalt Dewalt's 12- and 14-inch dry/wet diamond blades are designed for general purpose, cured concrete, asphalt, green concrete, and fast cutting applications


Dewalt's 12- and 14-inch dry/wet diamond blades are designed for general purpose, cured concrete, asphalt, green concrete, and fast cutting applications using cut-off saws, block saws and walk-behind saws. The diamond-cutting surface is used to maximize speed of cut and longevity. The diamond segments are laser-welded for durability while the blade core reduces vibration and distortion at high operating temperatures.

The arbor diameter is adaptable for use on tools that have 1-inch arbors, while a pin hole on the 12- and 14-inch blades is used to hold the blade on walk-behind saws. Graphics on the blade indicate wet or dry capability, recommended applications and tools, and safety information.

Wacker's Advantage and Advantage Plus diamond blades are good alternatives for a contractor cutting specific material all day with a hand saw. Because the contractor is cutting the same material, the blade will last longer than a high-speed general-purpose blade. The diamond blades range from 12 to 20 inches in diameter for five applications. This line of blades can also be categorized into four qualities of standard, heavy-duty, ultra, and extreme, and have wet and dry applications.

Makita's Mforce 7 1/4 inch X 24 tooth carbide-tipped blade comes equipped with six cutting surfaces and a two-pointed tip. The face of the tooth is beveled and has 10-degree angles that create sharp cutting edges that shear the wood instead of chipping away for a faster cut. The blade also features a thin kerf design to pull less power from the tool giving operators a much more efficient cut.

Metabo Corp.

The SXE400 3 1/8-inch orbital disc sander from Metabo provides increased flexibility for use in sanding applications. The Variospeed full-wave electronic speed control allows the sander to work in several applications, including woodworking, automotive bodywork, fine metalworking and polishing. Weighing 3.3 pounds, the SXE400 is easily maneuverable and its low 4 1/8 inch profile makes the sander compact enough to get into confined spaces difficult to reach with larger sanders. The small 3 1/8 inch sanding disc diameter enables even pressure to be exerted over the entire sanding surface, resulting in clean sanding on narrow surfaces.
