A mortising attachment is designed to help you cut square or rectangular holes, known as mortises, in wood. These attachments fit onto a drill press or similar tool, turning it into a mortising machine. This makes it easier to create precise mortise and tenon joints for woodworking projects like furniture or doors. By using a mortising attachment, you can save time and get cleaner, more consistent results compared to chiseling by hand.

Most mortising attachments are made to fit a range of standard drill presses, but compatibility can vary.

• Check your drill press’s size and spindle type before purchasing.
• Some attachments come with multiple bushings or adapters to fit different models.
• Always review the product details to make sure it matches your equipment.

Setting up a mortising attachment usually involves a few steps:

1. Secure the attachment to your drill press according to the instructions.
2. Install the correct size chisel and bit for your project.
3. Adjust the fence and depth stop for accurate cuts.
4. Test on a scrap piece of wood to fine-tune the alignment.

Safety is key when working with power tools and attachments.

• Wear safety glasses and hearing protection.
• Keep hands clear of moving parts and use clamps to secure your workpiece.
• Double-check that the attachment is firmly mounted before starting.
• Work at a steady pace—don’t force the tool.

Regular cleaning and maintenance can help your mortising attachment last longer.

• After each use, brush off wood chips and dust.
• Wipe metal parts with a dry cloth to prevent rust.
• Lubricate moving parts as recommended in the manual.
• Store the attachment in a dry place when not in use.
