Adjustable Height and Rotating Head Provide Versatility
Setting up the 14-651 is a breeze thanks to features such as the easy-access 3/8-inch-capacity drill chuck and adjustable rack-and-pinion fence. A height attachment increases the mortiser’s capacity by 1-3/4 inch, and if you still need more height, you can simply turn the 14-651’s head 180 degrees to mortise off-table.

Engaging and releasing via an efficient rack-and-pinion system, the 14-651’s head features an adjustable dovetail option for intricate jobs. The lever locks down and is long enough to provide that extra torque you need to mortise especially hard woods.

Additionally, the adjustable depth stop locks down, so you don’t have to worry about cutting too deep, and a chuck key/hex wrench simplifies bit and chisel changing.
