About

Secure and Stable Fixation – Designed specifically for square hole drill bits, this heavy-duty steel bracket firmly secures your tool during operation. The stable structure helps reduce movement and vibration, supporting smoother and more controlled mortising work.

This adapter allows your compatible drill to support square hole mortising applications. Note: Drill, square hole drill bit, and mortiser are not included.
Adjustable for Precision Work – Features adjustable height and angle settings to accommodate different project requirements. Ideal for woodworking tasks such as furniture making, cabinetry, and general mortise and tenon joinery.
Durable All-Steel Construction – Made from solid steel casting for strength and long-term use. The sturdy build helps maintain alignment during drilling. For storage in humid environments, applying protective oil is recommended to help minimize surface rust.
Easy Installation and Removal – Designed for convenient setup and disassembly, allowing quick attachment or removal when switching between drill functions. Package includes 1 square hole drill bit adapter, 3 wrenches, and 1 screwdriver for installation support.
