Bosch Professional Forstner Drill Bit (for wood, Ø 15 mm, length 90 mm, drill accessories)

Product Information

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. Forstner bits have a number of advantages over other bit types. Here they are, and as a woodworker, they can all give you greater control and alternatives. More smoothness and precision Sizes range from ¼-inch to 2 ⅛-inch bits, offering versatility. The ⅜-inch shank means they’ll fit a wide choice of consumer and professional power and bench drills. The most interesting feature is the design of the teeth. Rather than following the same pattern, they become more aggressive as the sizes increase—providing faster cutting when needed. 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.

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 Not everyone needs an extensive collection of Forstner bits. For some people, a Forstner drill bit will be a little-used part of their tool kit. Nevertheless, when the occasion arises, the INTOO Forstner bit set offers an affordable solution when compared to the cost of hiring a tradesperson. 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. 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.

N.B These Forstner bits are designed for use in side grain, for end grain boring Sawtooth cutters are recommended. 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. 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. 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

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 Metric sizes 10 to 12.7mm have 6mm shanks 14 to 30mm have 8mm shanks, above 32mm they have 10mm shanks. Bits are 90mm overall length. Forstner bits allow for larger holes and bores. Twist drills are only available in a limited number of sizes. Forstner bits are introduced and overlap some of the sizes before progressing to very large diameters of several inches. Affordable optionSome 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. A short centring tip with two main and one periphery (toothed-edge) cutting edges enable smooth splinter-free drilling Although most tools and accessories in the United States are still manufactured in inches, there’s a definite increase in imported products that use the metric measurement system. This is particularly true of things like cabinet hinges and other woodworking fixtures and fittings. When using standard American bits, the fit may be poor. 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.

While not cheap, these are a worthwhile investment for both serious DIY enthusiasts and professionals. Product SpecsThe plastic case has limited durability and the manufacturing quality is occasionally inconsistent, but this bit set is a good alternative for the DIY woodworker who wants something more than a budget Forstner bit set. Product Specs 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.

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. MaterialWhile 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. 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. The majority of Forstner drill bits are made of High Speed Steel (HSS). HSS drill bits are typically titanium-made drill bits and have a titanium oxide coating. They’re durable, resistant to corrosion, and can drill through wood and steel. It depends on the kind of hole you want. Spade bits work faster, but the hole is often ragged. They’re often for construction, where pipework needs to go through softwood lumber for example. A Forstner bit is slower but leaves a clean finish. It can make flat-bottomed holes, which a spade bit cannot. Q: Can Forstner bits be used with a hand drill, hammer drill, or impact driver? 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
