Cutting tool materials based on silicon nitride include fully dense Si3N4 and SiAlON materials, which are solid solutions of alumina in Si3N4. Fully dense Si3N4 can have fracture toughness nearly as high as cemented carbides, high strength and a low coefficient of thermal expansion, which result in very good thermal shock resistance. The silicon-based ceramics are excellent in maintaining hot hardness at temperatures higher than those suitable for cemented carbides, and are tougher than aluminium-based ceramics. Tools made with this material are excellent for turning grey cast iron at cutting speeds over 400 m/min, and are also used for milling and other interrupted operations on grey iron. Coolant can be used for tuning applications. SiAlONs are typically more chemically stable than Si3N4 but are not quite as tough or resistant to thermal shock. They are mainly used in rough turning of nickel-based superalloys.

In general, ceramic cutting tools have found applications principally in hard turning and milling cast irons and superalloys and in finishing hardened materials. For cutting tools, two kinds of ceramic composite materials are used, which can be differentiated according to the matrix materials. There are ceramics based on aluminium oxide (Al2O3) and silicon nitride (Si3N4). The key to successful application of ceramic cutting tools is to remember that they can take far more heat than do carbides, because they soften in the range of 2200°C versus about 870°C for carbide tools. Aluminium oxide-based ceramics are divided into pure, mixed and reinforced ceramics.

Alumina reinforced with SiC whiskers is the toughest and most resistant to thermal shock of the Al2O3-based ceramics. SiC whiskers used for reinforcement are discontinuous, rod- or needle-shaped fibres in the size range of 0.1–1 µm in diameter and 5–100 µm in length (about 100 times longer than they are wide). The incorporation of SiC whiskers into the ceramic matrix results in the increase of strength, fracture toughness, thermal conductivity, thermal shock resistance and high temperature creep resistance. Because they are nearly single crystals, the whiskers typically have very high tensile strength on the order of 7 GPa and elastic Young’s modulus values up to 550 GPa. Unlike other such materials, it can be run with coolant. High-speed finishing of nickel/cobalt-based superalloys is a typical application for whisker-reinforced ceramic cutting tools.

The Picatinny rail, also known as a MIL-STD-1913 rail, is a military standard rail system that provides a mounting platform for firearm accessories.

It’s not really a good habit to gang up dovetails. In many cases ganging them up together can result in both dovetails being out of square or misaligned or both and thereby the two dovetails end up being different sizes. Also, the very practice we need when we begin dovetailing is denied by introducing something we never really do in practice.

If you are a beginner, we recommend our sister site, Common Woodworking, which takes you through how to make a dovetail step by step:

We tend not to use the coping saw method for the majority of fine woodwork and furniture making, as it is not as precise and it takes quite a bit of practice to get as accurate as Paul is at it. There is also risk of tear-out. So for fine work we would use the method as seen in our making a dovetail video above. Paul might use a coping saw for rougher carpentry, but the cuts are consistently finer when done with the chisel.
