10 Best Mortise Attachments For Drill Presses 2026 in the United States

The Rikon Morticing Attachment is designed to fit a wide range of drill presses, supporting quill diameters from 40 mm up to 75 mm, which covers many common drill press sizes between 13 and 34 inches. This versatility in compatibility is a strong point, making it likely to work with your existing drill press. The kit includes four chisel sizes (1/4", 5/16", 3/8", and 1/2"), offering flexibility for different mortising tasks. The chisels are made from high carbon steel with a bevel edge, which should provide good durability and cutting precision.

Installation is generally straightforward thanks to included collar adapters, a fence, and hold-downs, though some users might find initial setup a bit fiddly if they're new to mortising attachments. The build quality is solid, weighing 18 pounds and featuring sturdy components that should hold up well during use. Adjustability is also decent, allowing you to position and secure your workpiece accurately.

This attachment is a good choice if you want to add mortising capability to your drill press without buying a separate machine, especially if your drill press matches one of the supported sizes and you need a variety of chisel widths. However, if you are a beginner, be prepared to spend some time on setup and adjustments.

This mortising attachment by BMTURNING is designed to convert a standard drill press into a functional mortising machine, allowing you to add mortising capability without purchasing a dedicated mortiser. It includes four chisel sizes (1/4", 3/8", 1/2", and 5/8"), covering a useful range for many woodworking projects. The drill bits are made of high-quality steel and are designed to cut quickly without clogging from sawdust, which helps maintain smooth operation.

Compatibility requires attention: the drill press collar diameter should be around 65mm but can be adjusted with reducer rings to fit smaller sizes, and the vertical space between the chuck and workbench must be at least 15.7 inches. Checking your machine carefully before buying is important. Installation is straightforward but requires proper measurement of your drill press. The set includes a locator, press block, side positioning rod, and fixed seat, which assist with positioning and stability during use.

The build quality is solid with iron parts and spiral flutes, though the tools are uncoated, which may affect long-term durability and rust resistance unless maintained properly. The included sturdy plastic case is convenient for storage and transport. The attachment offers decent adjustability, allowing precise alignment for square or circular mortises, adding versatility to your woodworking tasks. This product provides a cost-effective method to add mortising capabilities to a compatible drill press, with a good range of chisel sizes and useful accessories; just ensure your drill press meets the size requirements and plan for careful installation and maintenance.

The YUCHENGTECH Bench Drill Locator Set is designed specifically for woodworking mortising tasks, offering a specialized attachment for square hole chisels. It works well with drill chucks sized between 3 to 16 mm and requires a drill press setup with a vertical clearance of at least 300mm, so it's important to check your drill press dimensions for compatibility. Made from high-quality 56HRC bearing steel, the set promises durability and sharpness with a wear-resistant cutting edge, which helps maintain performance over time.

The tool is intended for softer wood materials like pine, ash, and density boards, making it well-suited for DIY woodworking or light construction projects rather than heavy-duty or metal work. Installation is straightforward, but since this is an accessory rather than a full machine, it must be paired with a compatible square hole drilling machine, not a regular electric drill. This requirement may limit ease of use for some buyers who do not already own or know how to use such a machine.

The product's design focuses on efficient removal of waste material during the mortising process, which can improve work speed and reduce labor. This attachment is a practical choice if you have a matching drill press and need a reliable, sharp tool for creating square mortises in wood, but it is less suitable for those seeking a universal or heavy-duty mortising solution.
