When drilling holes greater than 1 ½" in diameter, Forstner bits and paddle/spade bits are particularly effective. Forstner bits excel in creating clean, flat-bottomed holes with precise diameters, making them ideal for woodworking and cabinetry projects. They produce less tear-out on the surface of the material, which is important for aesthetic finishes.

Paddle/spade bits, on the other hand, are designed for quickly removing large amounts of material and can drill holes significantly bigger than 1 ½". Their simple flat blade design allows for aggressive drilling, which is useful for tasks such as running electrical wires or plumbing where large holes are required in wood.

Both types of bits provide advantages in terms of speed and hole quality for larger diameters, which makes them suitable for the specified drilling task. In contrast, other options like twist bits, hole saws, and auger bits may not perform as efficiently for such large diameter holes in terms of removal speed, precision, or overall finish quality.
