Whether you're building furniture, crafting cabinetry, or working on DIY projects, this adapter turns your standard drill press or hand drill into a precision square hole drilling machine.
This clever attachment fits perfectly with benchtop drill presses and hand drills featuring clamps between 38-55mm (1.5-2.2 inches) in diameter. The all-steel casting construction provides the stability and durability needed for consistent, accurate drilling results. You'll notice the difference immediately—no more struggling with makeshift solutions or investing in expensive dedicated mortising equipment.
Installation takes just seconds, making it perfect for both professionals and hobbyists who need to switch between drilling tasks quickly. The adapter's design ensures minimal vibration and maximum precision, giving you clean, square holes every time.

From creating door hinges and furniture joints to crafting custom woodworking projects, this adapter opens up endless possibilities. The sturdy steel construction means it can handle the demands of regular workshop use, though we recommend storing it in a dry environment to prevent surface rust—easily maintained with a wipe of protective oil when needed.
Perfect for woodworkers, furniture makers, and DIY enthusiasts who want professional results without professional equipment. The Square Hole Drill Bit Adapter pays for itself in just a few projects, saving you time, money, and frustration while delivering the precision you need for beautiful, lasting craftsmanship.
