Saw-tooth Forstner bits have a series of teeth that resemble a coarse saw blade. These are designed for more aggressive cutting and are particularly good for end grain. The Precision Shear design, which was introduced by Freud has a serrated edge with a steep interior angle that produces a very sharp edge, and rapid, chisel-like cutting action. Material A major advantage of a Forstner bit is that it’s made to drill flat bottom holes. Rather than drilling all the way through, a flat bottom hole has smooth sides, a small pilot point in the center, (and the name suggests) a flat bottom. These are great for dowel joints, or fitting catches in cabinet doors. Unlike a spade or twist drill bit, Forstner bits have no problem cutting at an angle and can drill partial or overlapping holes. The latter makes for fast material removal when cutting mortises, particularly when used in a drill press. Forstner bits are also popular with woodturners, allowing large, deep holes to be cut on a lathe. Many DIY users will be fine to use HSS bits on their own. However, professionals or individuals who use these tools frequently may want to invest in a carbide Forstner drill bit set. Contractors and tradespeople who are regularly employed on new builds or remodeling projects need tools that combine high performance with great value. This Porter-Cable Forstner bit set meets those demands and more. Like the brad-point bit, this basic bit has a sharp cutting tip and fluted edges to remove waste when the hole is drilled. The twist bit is a multi-purpose bit that may be used on wood, thin metal, and plastic in the home. Countersink drill bit

BASYNOL also produces a variety of imperial size Forstner drill bits, but not in a set. Product SpecsOne or two manufacturers use High Carbon Steel (HCS). HCS is slightly softer than HSS, though the term “softer” has to be taken into context. These bits are still hard enough to drill into wood and wood-based materials. HCS bits won’t cut aluminum and other soft metals, or tile and masonry. Bit Size & Number of Bits A standard twist drill is fine for drilling holes of small diameters, so Forstner bits are not usually found below ¼-inch. Sometimes, the smallest bit in a set will be ½-inch. The largest is usually 2 to 2 ⅛-inch. Although larger Forstner bits are available, they’re usually sold individually as they’re bigger than most people need. Metric Forstner bit sets are also available. These can be very useful when fitting cabinet hinges, for example, as the hardware is often metric. Imperial bits can be close to the same size, but not close enough for a good fit. While larger bits might be required for some tasks, the sizes offered in this kit will be adequate for most DIY purposes. The larger bits may also cause a problem for some hand drills or drill drivers, which may not have the torque to drive larger diameter bits. Product Specs The eight-piece Kowood Fostner bit set ranges from ¼-inch to 1 ⅜-inch and has tungsten carbide tips for durability. The three smallest diameter drills use an interesting combination of a Forstner-style tip with a twist drill body, which helps clear waste and prevents them from overheating in deep holes.

Although HSS for overall construction is common, Diablo Forstner bits are machined with greater accuracy than many competitors. The central spur has a fine point to ensure precise initial positioning and honed cutting edges provide rapid material removal. Consumers should exercise extreme caution when operating a power drill, as these bits are sharp and could potentially cut one’s finger. The 14-piece bit set has diameters from ¼-inch to 2 inches, providing the versatility required to undertake multiple tasks. For example, the bit range covers all standard cabinet hinge sizes. While not cheap, these are a worthwhile investment for both serious DIY enthusiasts and professionals. Product Specs Credit subject to status and affordability. Terms and conditions apply.

When it comes to Forstner bits, there isn’t much to talk about in terms of accessories, unlike with power tools. However, you’ll probably want to choose a set of pieces that comes with a handy storage container. This will allow you to maintain the pieces in good condition for a long time while also keeping them organized. What Are the Benefits of Forstner Bits?

The unusual open tooth blade pattern focuses on fast material removal (because time really is money for a professional) and maintains a good quality finished cut. The reduced shank means they’re designed to fit all pro-grade power drills. An important factor to consider is the units in which your Forstner bits will be measured. Imperial and metric sets are the two alternatives here; the former will feature inch-sized bits, while the latter will have millimeter- and centimeter-sized bits. If you’re based in the United States and generally work with local materials, choose inch-sized bits. Otherwise, a metric-sized set may be preferable. Number of bits The countersink drill bit is a special bit that is used to generate a pilot hole with a wider opening at the top for countersinking screw heads. The countersink drill bit, which is primarily used on wood, allows you to insert the fastener deep enough that the head does not protrude above the surface of the material. Forstner drill bits
