3-5/8" T-Shank Straight Cut Jigsaw Blade (100/Pack)

T118AF Jigsaw Blade For Sheet And Thin Metal

T118AF jigsaw blade identifies this Bosch 3-5/8 inch T-shank straight cut jigsaw blade designed for trade use on metal. The blade uses bi-metal construction, so the cutting edge and backing are matched for long life and flexibility during demanding cuts. This Flexible for Metal blade is designed for cutting sheet metal and thin metals, both ferrous and non-ferrous, which keeps one blade type working across common shop metals. Tooth spacing at 24 TPI supports straight cuts and long life in thin stock, helping reduce grabbing and distortion. A wavy set and milled tooth design shapes the kerf for controlled cutting in metal, which supports consistent line tracking. The T-shank design provides maximum grip and stability in compatible saws, so the blade seats securely under load.

Key Jigsaw Blade Details For Metal Work

• The bi-metal construction is engineered for long life and greater flexibility, so the blade withstands tight curves in thin metal without giving up cutting performance.
• The blade is designed for cutting sheet metal in the 10-16 gauge range, giving installers a defined working window for typical metal cabinet and fabrication tasks.
• The blade also handles thin metals from 1/16 inch to 1/8 inch, ferrous and non-ferrous, so one setup covers a mix of material types on the same job.
• The 24 TPI tooth design focuses on straight cuts and long life in thin metal, which supports cleaner edges and less rework on finished parts.
• The wavy set and milled teeth form a controlled kerf in metal, helping the blade track accurately along layout lines and manage chip load during the cut.
• The T-shank design is built for maximum grip and stability in the jigsaw, which helps keep the blade firmly held during longer straight or curved cuts in metal.

Installation And Saw Fit For T-Shank Blades

This bi-metal T-shank jigsaw blade is described as fitting 90% of all current jigsaw makes and models, so it mates with most modern professional and serious DIY saws using this interface. T-shank blades are suitable for jig saws from Bosch, Dewalt, Hitachi, Makita, Milwaukee, and others named in the description, so installers using those brands can match blade and tool by shank style. The T-shank profile supports maximum grip and stability in the saw clamp, helping the blade stay aligned for straight cuts in thin metal. The 3-5/8 inch length gives a compact working reach, which is well suited to controlled cuts in sheet and thin stock where access and maneuverability are important.

Using This Bi-Metal T-Shank Blade In Metal Work

Where This T118AF Jigsaw Blade Performs Best

This 3-5/8 inch bi-metal T-shank jigsaw blade is intended for sheet metal and thin metal work, so it fits jobs such as panels, brackets, and light structural pieces within the stated thickness range. Its design for sheet metal 10-16 gauge focuses the blade on common light-gauge steel and similar materials, keeping cutting performance tuned for those thicknesses. The stated capability for thin metals 1/16 inch to 1/8 inch, ferrous and non-ferrous, means it is suited to work in steel, aluminum, and other metals that fall in that band. A type of cut defined as straight cuts and long life shows that the tooth layout favors accurate line-following and durability rather than rough, fast removal, which benefits visible edges and parts that must fit precisely. Because the blade is also described as ideal for straight or curved cuts, it supports contour work in panels along with straight-line cutting on rails or trim pieces.

How Design Details Support Repeatable Metal Cuts

The bi-metal construction noted for long life and greater flexibility helps the blade resist breaking while flexing through curves or during tight radius work in thin sheet. This flexibility keeps the cutting edge working instead of failing under stress when the jigsaw is steered through curved paths. The wavy set and milled tooth design shapes the cutting profile and kerf, which supports smoother progression through metal and helps manage heat and chip evacuation. With 24 TPI, tooth spacing is optimized for thin materials, so each stroke removes smaller chips and reduces snagging that could distort sheet metal. The T-shank design built for maximum grip and stability means the blade locks firmly into compatible saws, which supports consistent plunge and line tracking over longer cuts. Because the product description specifies that the T-shank blades are suitable for jig saws from Bosch, Dewalt, Hitachi, Makita, Milwaukee, and other named brands, installers can align their blade selection with these tools by shank style for repeatable performance.
