The Bosch top-handle jig saw provides plenty of power coupled with outstanding handling and accuracy. Finish carpenters and kitchen and bath installers will appreciate the powerful 6.5 amp motor and variable-speed control, making this saw an excellent choice for curve-cutting. A dial on the back of the tool controls the maximum speed. the accelerator trigger regulates the operating speed. This jig saw is engineered with a precision-machined plunging mechanism and low-vibration design, delivering enhanced accuracy and extremely smooth operation. Also, it was designed with soft grip areas for solid handling. The sturdy die-cast aluminum footplate includes a steel insert and on-board storage of bevel hex key. The multidirectional blade clamp delivers superior grip of T-shank blades (but it does not accept u-shank blades). The toolless T-shank blade-change system affords fast blade insertion and removal.
