This BOSCH miter saw combines professional cutting capacity with outstanding portability to deliver a truly mobile, cordless solution to the jobsite. The GCM18V-08N Surgeon bare tool kit features an 8-1/2 In. single-bevel, sliding compound miter saw delivering a 3-5/8 In. nested crown cutting capacity, cutting from 47° left to 47° right against the fence, which is an exceptional range for a cordless 8-1/2 In. miter saw. At a manageable 31. 5 Lbs. (tool only, not including battery), this saw features easy portability while still providing a 10-5/8 In. crosscut capacity. It features BOSCH's MEGAWATT Technology, a BOSCH-exclusive brushless high-performance motor and drive-train system engineered to take full advantage of the additional power generated by 8. 0 Ah and 12. 0 Ah CORE18V batteries (sold separately). In testing, the saw delivers 377 cuts per charge with a CORE18V 8. 0 Ah Performance Battery. With an accurate laser guide system to precisely align the cut line to the blade, the saw is engineered with precisely centered sliding bars, leading to a very smooth and easy saw sliding. It provides a dust chute and dust bag, providing efficient dust collection.
