BMTURNING Mortising Attachment for Drill Press – Precision Tenon & Groove Kit

Transform your drill press into a dedicated mortising station

The BMTURNING Mortising Attachment is designed for woodworkers who value precise joinery and tidy workflows. This kit adds a focused mortising and grooving capability to an existing drill press, helping you create clean mortises and seamless grooves with repeatable setup. Rather than relying on trials and error, you can approach each project with a practical toolkit that emphasizes accuracy, speed, and portability.

What you get is a thoughtfully organized system that takes you from rough material to well-defined mortises with minimal downtime. The included components work together to establish consistent alignment, stable drilling, and reliable positioning—so you can focus on the cut rather than chasing alignment.

What’s included

• Locator, press block, side positioning rod, fixed seat, and other accessories that create a complete mortising workflow
• Four mortise chisels sized for common joints: 1/4 inch, 3/8 inch, 1/2 inch, and 5/8 inch

Key features and benefits

• High-quality steel drill attachments resist deformation and deliver consistent cutting performance
• Designed to minimize sawdust blockage for smoother mortising and faster chip clearance
• Rugged construction with a focus on hardness and edge retention for repeated use
• Collar compatibility and clearances are specified to fit typical bench drills, with a 65 mm collar and reducer rings
• Clearance guidance: ensure the vertical distance between the drill chuck and workbench is adequate (at least 15.7 inches) before installation
• Converts a drill press into a precise mortising and grooving machine, supporting both mortises and grooves in one setup
• Sturdy plastic storage box keeps the components organized and portable for on-site or shop use

How to use and practical considerations

Before ordering, double-check your bench drill for compatibility with the 65 mm collar and reducer range (60 mm, 55 mm, 52.5 mm, and 40 mm). The system is designed to align the workpiece securely, minimizing drift while you work. With the included chisels, you can tackle common joinery tasks such as hinge mortises, frame notches, and tight-fitting tenons with fewer adjustments between cuts.

Real-world use cases include cabinetry, furniture frames, decorative panels, and other projects where repeatable mortises contribute to cleaner joints and faster assembly. The kit’s modular design supports a logical workflow: set up, center and align with the locator, drill with the press block, and refine with the mortise chisels. When you’re finished, the plastic box makes transporting the setup between shop and job-site convenient.

Usage tips and care

• Maintain consistent feed pressure and allow the tool to do the work to maximize edge quality
• Regularly clear sawdust from the chuck area to prevent clogging and keep tolerances tight

Note: This attachment is designed as a precision accessory for compatible drill presses. Review the collar size and clearance requirements to ensure a proper fit for your setup.
