The 5007MG 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 5007MG 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. The 5007MG includes a Makita 7-1/4 In. 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.
