Take on metalwork with confidence using the Bosch 3 in. Bi-Metal T-Shank Jig Saw Blade, engineered for durability, precision, and smooth cuts in tight spaces. This 5-pack is built to handle medium-thin metals with ease, so you can move from rough outlines to precise finished edges without swapping blades mid-project.
Why this blade stands out:
-
Bi-Metal construction: Combines a tough tooth material with a flexible backing for long blade life and reduced breakage when cutting metal.
-
3 in. length: Shorter blade design allows tighter curves, intricate cutouts, and cleaner flush cuts in confined areas.
-
14 TPI: Optimized for fast, accurate cuts in medium-thin metals, delivering smoother edges with fewer chipping or burrs.
-
T-Shank compatibility: Universal fit for most modern jig saws, ensuring quick tool changes and secure blade retention.
-
Dimensions you can rely on: 0.04 in thick and 0.3 in wide, engineered to glide through ferrous and non-ferrous metals up to 1/8–1/4 in thick.
-
Value-packed: Sold in a 5-blade package so you can complete multiple cuts or stock up for future projects without constant reorders.
What you can cut and where this blade shines
Designed for metalworking tasks, this blade is ideal for cutting medium-thin ferrous and non-ferrous metals such as steel, aluminum, brass, copper, and light-duty sheet metal. Use cases include:
- Sharp interior cutouts for electrical panels, brackets, and housing enclosures
- Precision curves on thin metal brackets, straps, and flashing
- Duct work components, metal trim, and lightweight hardware where a tight radius is required
How this blade improves your project outcomes
Compared to standard single-material blades, the Bosch bi-metal design delivers greater durability under repeated metal cutting, reduces blade drift, and provides a cleaner finish on edges. The 3 in. length and 14 TPI configuration are tailored for controlled, repeatable cuts in tight spaces, helping you achieve professional results without traceable tear-out or burrs.
Practical tips for best results
- Secure the workpiece firmly and use slow, steady feed rates to minimize heat buildup and blade wear.
- Mark your cut line clearly; for tight curves, practice on scrap metal to dial in your radius before the final pass.
- Lubrication isn’t always necessary, but a light spray of cutting lubricant on tougher metals can improve edge quality and blade life.
- Match the jig saw’s speed to the material—lower speeds for metals help prevent tooth dulling and overheating.
Choose the Bosch 3 in. Bi-Metal T-Shank Jig Saw Blade in 14 TPI when you need reliable, repeatable cuts in metal with a blade that resists dulling and breakage. Perfect for professional shop workflows and serious DIYers tackling metal projects where precision matters.
