Best Hole Saw For Door Knob Review (2024 Update): Cut Clean, Drill Fast

Hole Saw for Door Knob Review: Cutting the Perfect Entry

Installing a new door knob requires a clean, precise cut for the latch and knob mechanisms. Enter the hole saw, a drill attachment that creates perfectly circular holes in wood and other materials. But with a variety of hole saws available, choosing the right one for door knobs can be tricky. This review explores key features to consider and offers insights on popular options.

Factors to Consider:

Size: Standard door knobs have a diameter of 2-1/8 inches (54mm). Select a hole saw slightly larger, typically 2-3/8 inches (60mm), to accommodate the latch and knob housing.

Arbor: The arbor is the central shaft that connects the hole saw to the drill. Ensure your drill has the appropriate size arbor, commonly ½ inch or ¾ inch.

Teeth: Bi-metal teeth offer a good balance between durability and cutting speed. For tougher materials, consider carbide-tipped hole saws.

Popular Hole Saw Options:

Several reputable brands offer quality hole saws for door knobs. Here are a few examples:

Bosch Daredevil Spade Bit: A good all-around option with bi-metal teeth for clean cuts in wood and soft metals.

Milwaukee Hole-Saw with Pilot Bit: Features a pilot bit that centers the hole saw for increased accuracy.

Freud Accu-Cut Bi-Metal Hole Saw: Offers a variety of sizes, including the perfect fit for door knobs, and a lifetime warranty.

Additional Tips:

For a clean finish, drill a pilot hole using a bit slightly smaller than the saw teeth. Clamp the door securely to prevent it from moving while drilling. Apply light pressure and maintain a straight drilling position. Utilize a drill press for maximum control and accuracy, especially for thicker doors.

Conclusion:

Choosing the right hole saw for door knobs ensures a frustration-free installation process and a professional-looking end result. By considering factors like size, arbor compatibility, and tooth material, you can select a hole saw that delivers clean, precise cuts for your door knob project.
