Bosch Professional 5-Piece Forstner Drill Bit Set (for Wood, Ø 15/20/25/30/35 mm, Length 90 mm, Drill Accessories)

Product Information

The price is almost unbelievably low, but there are reasons for that. Although this set is advertised as “tungsten steel” we believe the bits are HSS. There is no box, which is disappointing but can be easily remedied. Some of the shafts are not perfectly straight, which results in holes that aren’t exactly the right size. However, this will be of little concern to those who buy these Forstner bits for high productivity in hard-working environments. Product Specs 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 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. BASYNOL also produces a variety of imperial size Forstner drill bits, but not in a set. Product Specs While available singly, Forstner bits are usually sold as boxed collections of eight or more. The best Forstner bit sets offer tremendous flexibility, great versatility, and excellent value.

Bosch Professional includes a wide range of high-quality accessories for wood such as machine wood drill bits, carbide hinge cutting bits and tungsten carbide tipped bits. All our drill bits for wood are specially designed to rapidly drill through wood with little force. The bits are made of high-quality steel and feature a precision ground point and cutting edge for clean, fast drilling. Forstner bits create clean, accurate holes—particularly those with a flat bottom, rather than one that goes all the way through the material. One common use is when fitting the type of hinge used for kitchen cabinet doors. They can also drill overlapping holes without deflecting, which allows for fast material removal when cutting mortises. Woodturners use them for boring out vases, making candle holders, etc. Q: Is a Forstner bit better than a spade bit? 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 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 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.

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. 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. 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 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.

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.

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. 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 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. 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
