A drill-press mortising attachment can be just as effective and it costs a lot less. <br> Although they vary in appearance, they all have three basic components: a fence, a chisel holder and a hold-down. Upgrading these parts to stabilize the workpiece and operating the drill press at the optimal speed are the keys to success.I get first-class results with my tuned-up mortising attachment. That means I don’t have to store a large, heavy mortiser that I would only use occasionally. On the drill press, I can slow the speed way down, too, so the bits don’t screetch and smoke. Drill press mortising is slower, but it’s much more pleasant, a lot quieter and much less nerve-racking than using a mortiser.<br>
