Bosch T118B jigsaw blade is a 3-5/8 inch T-shank straight cut blade designed for cutting sheet metal and thin metals. The blade is part of Bosch Basic for metal blades, which are described as the economical choice for cutting sheet metal and thin metals in both ferrous and non-ferrous materials. This jigsaw blade uses a T-shank design for maximum grip and stability, so it seats securely in compatible tools during straight-line and fast cuts. The blade length supports controlled straight cuts in medium-thin metals between 1/8 inch and 1/4 inch, which suits many shop and jobsite metal tasks. The manufacturer identifies this blade as part number T118B, which helps match it to tool charts or existing setups where that reference is already used.
This HSS T-shank jigsaw blade is described as fitting 90 percent of all current jigsaw makes and models, so it is intended to drop into a wide range of modern tools that accept T-shank blades. The T-shank format is suitable for jig saws from Bosch, Dewalt, Hitachi, Makita, Milwaukee, and others, giving flexibility when standardizing blades across a mixed-brand tool fleet. The T-shank design supports quick blade insertion into compatible chucks, and the focus on maximum grip and stability helps the blade stay aligned in the guide during fast straight cuts in thin metal. By matching this T118B blade to a jigsaw that accepts T-shank blades, users can keep a consistent interface for metal cutting tasks.
This 3-5/8 inch T-shank straight cut jigsaw blade is specified for medium-thin metals between 1/8 inch and 1/4 inch, so it suits work on sheet metal and similar thicknesses in both ferrous and non-ferrous stock. The Basic for metal designation ties the blade directly to these materials, guiding it toward tasks like cutting sections out of thin metal panels or trimming metal pieces to length within that thickness window. The blade teeth use a wavy set and milled pattern, which shapes the cutting edge for working in thin metal where control along the cut line is important. With a tooth layout of 11-14 progressive teeth per inch, the blade changes tooth spacing along its length, which affects how it engages the metal for both speed and smoothness in straight runs.
The Bosch T118B jigsaw blade is identified as a straight cut blade, which ties its design to straight-line cutting in thin metal rather than curved work. The T-shank design is specified for maximum grip and stability in the jigsaw, which supports repeatable cutting performance by helping keep the blade firmly seated during operation. The 11-14 progressive teeth per inch arrangement provides a varying tooth pitch that can help manage chip load as the blade moves through 1/8 inch to 1/4 inch metals, supporting a balance between cutting speed and control. The combination of wavy set and milled teeth with the T-shank mounting allows this blade to work as part of a controlled cutting setup in many jigsaws that accept T-shank blades.
