Product Information

Continue pressing in carefully with the trigger engaged until you reach the desired bore depth. Then, you can release the trigger and carefully slide the Forstner bit’s head out of the hole as it slows down to a stop. At this point, your hole is effectively finished. In terms of their actual form, forstner bits are typified by their outer cylindrical rim, called the guide rime. These rims come in several different styles, but always allow a hole made by that bit to come out smooth and even. This rim even guides the bit at the beginning of a cut, which can be crucial when making a series of identical bores. Keep it sharp: Forstner bits work best when they are sharp. You’ll know your bit is getting dull if it “walks” around a board’s surface excessively when you are attempting to drill with it. These bits should be replaced or sharpened to prevent excessively tearing up the exterior of your workpiece.

As a result, they are often compared to spade bits and even hole saws. Forstner bits are considered to be more versatile than spade bits, though, because they can effectively bore holes at an angle or on the edge of a work piece. In particular, any crafter worth their salt should know about Forstner bits. Not only that, but those same crafters should know how to use a Forstner bit in both a hand drill and a drill press. To begin with, a Forstner bit is a unique type of boring drill bit that allows a woodworker to create clean, flat-bottomed holes in a workpiece.Once your Forstner bit is inserted and secured, mark your workpiece to indicate the precise center of the desired hole. This can be done with a pencil or chalk. If you intend to press all the way through and create a full hole, you can continue from this point. Before doing so, be sure to clean out any excessive sawdust to prevent extra heat build-up over your Forstner bit’s blade. How to Use a Forstner Bit with a Hand Drill

Start slowly by making an initial indent that allows your bit’s guide to steady itself. You’ll also need to apply some pressure to your hand drill at this point, but not so much that your bit begins to “walk” around the wood’s surface. As you’ve seen, this type of drill bit is exceptionally useful in a variety of hole-making situations including those that occur at angles and on the edge of a workpiece. You also now know the basics of using this kind of a bit, regardless of whether you are using a hand drill or a drill press. Ideally, you should reach your unit’s slowest speed after reaching your target depth. Keep your Forstner bit spinning at that speed as you carefully withdraw the bit. This will create a cleaner vertical edge within the hole.Hold it steady: Using a Forstner bit to drill a hole on a vertical surface can be challenging due to a hand drill’s weight distribution. To counteract this, you may want to add an auxiliary handle to your drill. This will give you a second support point that can keep your hole perfectly straight as it is being made.

This will prevent blowouts, especially if you intend to bore all the way to the other end of your workpiece. Step 2: Attach Your Bit and Mark the Center Once that is done, you’ll want to mark (with chalk or a pencil) the center of the circle you wish to bore in your target surface. This will allow you to align your hole more reliably once you begin to cut into that structure’s surface.
