The Makita 5007MGA 7-1/4 in. Magnesium Circular Saw with Electric Brake features highly durable magnesium components and a powerful 15 AMP Makita-built industrial motor. The 5007MGA seamlessly balances weight, power, durability, and ease of use, making it the most refined circular saw on the market. A built-in dust blower clears the line of cut for more accurate and precise cuts. The 5007MGA is built for framing walls, floors and roofs using a range of dimensional lumber and dense engineered lumber, including LVL, PSL and I-Joists, headers, and microlams; as well as ripping panels such as plywood, OSB, particle board, and dense structural panels. Other applications include plunge and bevel cutting, as well as masonry and metal cutting. The 5007MGA includes a Makita 7-1/4” Premium Ultra-Coated Framing Blade with Advance Tooth Design. The "M" shaped tooth design features a two-pointed tip and two 10 degree bevel face to maximize cutting performance for a faster, cleaner and longer lasting cut. The carbide tips are specifically set to withstand the harshest conditions such as plowing through nail-embedded wood. The blade is also ultra-coated to reduce heat and pitch build-up for faster, smoother cutting, with special Makita heat vents strategically set to dissipate heat and increase performance.
