We’ve covered cheap mortising attachments here before, but this Orion mortising attachment at Woodcraft looks like it’s a much higher grade tool.
The Orion supposedly fits most drill presses with 2-5/8″, 2″, 1-7/8″, 1-1/2″ (think DP350) diameter quills. It features a micro adjustable fence which can hold work pieces up to 4-1/2″ thick. The mortising attachment also comes with hold down rods, a setup block, and 1/4″, 5/16″, 3/8″, and 1/2″ chisels.
Woodcraft is also selling many other clearance items at 50% off. The sale is one week only — so assuming it they start their calendar week on Monday, you have only 5 – 7 days left to shop.
