The Bosch 4100 Table saw offers radical new features and enhancements that make the 4100-series a precise, durable and high-performing table saw. The 4100 features the industry's first-ever modular smart guard system. Other innovations include a super-durable sub-base with carry handles, Bosch-exclusive SquareLock Rip Fence with auxiliary fence slots, and a t-slot miter gauge. With all these features, the new 4100-Series 10-inch portable table saw will keep Bosch at the top of the category. The Bosch modular smart guard system is a ground-breaking new design for portable table saws that includes a blade guard, riving knife, and anti-kickback pawls. The riving knife prevents material from pinching the blade and offers positions for: full upright, "splitting," and "non-thru" cutting. For professional tools, durability is an essential component of jobsite value. The 4100 also offers Constant Response Circuitry with Soft Start for smooth ramp up speed and to maintain speed under load. At 29 by 21-1/2-inches square, the table saw provides the most usable tabletop space available with a 25-inch rip capacity that can easily handle sheet goods or larger stock. The arbor lock system makes blade changes quick and easy. On-board storage for accessories and the Smart Guard System makes it easier to move between jobs.
