Oftentimes, two sets will come with the same minimum of maximum sizes—one may contain eight bits, while the other has 10 or 12. The latter of the two sets will have a greater variety of sizes, thus increasing versatility. However, it’s important to consider quality. While a large number of bits at a low cost might suit the DIY user, this set is unlikely to meet the standards of a professional. The 16-piece set comes in sizes from ¼-inch to 2 ⅛-inch bits and the quality is such that they will most likely appeal to fine furniture makers and other woodworking professionals. Product Specs At first glance, it’s difficult to differentiate these tools from competitors, but Freud Precision Shear Forstner bits are forged (hammered into shape under high pressure with still molten metal). This makes them very hard, leading to superior edge retention and longer life.

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 At first glance, all Forstner bits appear very similar. However, there are differences in the materials used, and the design of the cutting edges. While these dissimilarities may be seemingly minor, they can make a big difference to efficiency. When selecting the best Forstner bit set, pay attention to its size to ensure it’ll cover the range of tasks you need it for. Tooth Type My own experience with Forstner bits is extensive. I was the owner of a woodshop for 11 years; I’ve also renovated two homes. I use Forstner bits for precision furniture-making as well as for punching holes through support beams in preparation for cabling. Some of the best Forstner bits cut like fine chisels, but sometimes speed is more desirable than great accuracy. Durability, edge retention, and price also play a part. In my opinion, the wide range of Forstner bit sets listed above provides a solution for (almost) every demand. FAQs While large collections of budget Forstner bits can sometimes be tempting, many users will never need the majority of those drills. Quality might also be a concern. The Basynol set is ideal for those who want well-made tools that might only be used occasionally, for the woodworker just starting out, or for those who need a particular metric size for cutting hinge holes, for example.

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. While ordinary drill bits are quite efficient, their cutting action can create ragged holes, particularly when working with larger sizes. You could use a spade bit, but they often vibrate or “chatter” and can be difficult to control.

While Forstner bits are primarily intended for use in drill presses, they’re frequently used in hand drills as well. When drilling holes for trunking or cabling, for example, Forstner bits cut cleanly and easily. By contrast, a spade bit often judders, making it difficult to control. Forstner bits produce less tear-out, too. One 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 Some techniques can overcome the problem, but the simple solution for making neat, precise holes is a Forstner drill bit. It has a central point called a spur that is designed for accurate positioning, sharp cutting teeth, and wings to clear waste. As a result, there is seldom the need to cut deep holes in several stages, as you do with standard twist drill bits. Drill bit diameters range from ¼-inch to 2 ⅛-inch. The bits come in a wooden box equipped with a clever tilt-out mechanism which presents them ready for use. Product Specs When you need a wood cutting or boring drill bit, Bosch Forstner bits are an excellent choice. Designed with a tooth-edge that reduces friction and heat, the innovative cutting edge ensures a smooth and splinter free hole. This also guarantees an improved durability and lifespan of the bit. Alternatively, an auger bit can be used to drill smaller diameter holes while still offering high precision drilling. Equipped with a heavy-duty self-feeding tip, Bosch auger wood bits offer high chip removal rate and low friction.
