The compatibility with 115/230V power sources makes it versatile for different workshop setups.

The handwheels control smooth linear and cross table motions, and the quick position table-mounted swiveling vise clamp accommodates angled workpieces, offering excellent adjustability for various tasks.

However, at 276 pounds, it is quite heavy, which might make installation and positioning challenging without additional help. The hinged chuck door provides easy access for bit changes, although the maximum chuck size of 0.5 inches may limit the variety of bits you can use. It has a solid warranty of 5 years and is ideal for professional woodworkers or serious hobbyists who require precision and durability in their mortising tasks.

The Powermatic Benchtop Mortiser PM701 is a robust and versatile tool designed for precision woodworking.

It's compatible with a variety of chisels, making it suitable for different mortising tasks.

The DELTA 17-924 Mortising Attachment is a solid choice if you want to add mortising capability to your drill press. It comes with four popular chisel sizes (1/4", 5/16", 3/8", and 1/2"), which covers most common woodworking needs. Compatibility is quite good since it fits drill presses with various quill sizes (38 mm to 66 mm), making it versatile for many users. Its build is sturdy, made of steel, so it feels durable and reliable. The included carrying case is a nice bonus, helping keep all parts organized and easy to store.

Installation is reasonably straightforward, though some users might find the setup a bit fiddly if they’re not used to attachments. The attachment offers a 4-inch capacity under the hold-downs and decent adjustability, letting you work with different sized pieces effectively. However, it’s a bit on the heavier side (over 18 pounds), which means it’s designed for more stable, stationary use rather than portability.

Though not the newest model on the market, this tool maintains good performance and has received positive feedback from users. It is best suited for woodworkers who already own a compatible drill press and want a reliable, no-frills way to cut mortises without investing in a dedicated mortiser. For those seeking something lightweight or very quick to install, there may be more modern options, but this DELTA attachment balances functionality and value nicely.
