T118BF bi-metal jigsaw blades for cutting steel, stainless steel and thin sheet metal. The HSS cutting edge bonded to an HCS body gives you a blade that stays sharp longer, flexes without snapping, and cuts cleaner than standard blades.
The T118BF bi-metal metal jigsaw blades are a solid choice for anyone cutting steel, stainless steel, or thin sheet metal on site. The blade combines a high carbon steel body with a high speed steel cutting edge — two different materials doing what each does best. The HCS body absorbs vibration and flex without cracking, while the HSS teeth handle the actual cutting and hold their edge far longer than a single-material blade would manage.
That combination matters more than it might seem. On a standard HCS blade, the teeth dull quickly on harder metals and the blade can shatter under flex stress. On an HSS-only blade, brittleness is the problem — they cut well until they don’t, and then they go suddenly. A bi-metal construction threads that needle. You get flexibility where you need it and hardness where it counts.
Where T118BF Bi-Metal Blades Earn Their Keep
These blades suit a wide range of metal cutting tasks: cutting steel box section, trimming sheet metal, working around pipework, cutting conduit runs to length, or making holes and notches in metal panels. Essentially, if there’s ferrous metal involved and you’ve got a jigsaw in your hand, this is a blade worth reaching for.
The 76mm blade length keeps things manageable for most sheet and section work without being unwieldy. The T-shank fitting is the standard across most modern jigsaws, so compatibility isn’t something you’ll need to think twice about on most machines.
Cost Per Cut
Extended edge retention means you’re not burning through a blade every other job. That’s the practical upside of bi-metal construction — more cuts before the blade goes blunt, which directly reduces your cost per cut over a run of similar jobs. On any kind of production or repetitive metalwork, that adds up quickly. Buying in boxes of five keeps things sensible from a cost and stocking perspective too.
Pro Tip: When cutting stainless steel, drop your jigsaw speed to around two-thirds and let the blade do the work — forcing the pace generates heat that will kill the edge far quicker than steady controlled cutting.
T118BF bi-metal jigsaw blades are used across construction, fabrication, electrical installation and general metalwork. Common jobs include cutting steel sections to length, trimming metal panels and ducting, cutting conduit and trunking, and working around pipework or structural steelwork where an angle grinder would be too aggressive or impractical. Sheet metal work is a natural fit, including stainless steel kitchen fitouts and HVAC panel cutting where a clean, straight edge matters.

Material: Bi-metal HCS body with HSS cutting edge
Suitable for ferrous metals
Shatter resistant construction

Not suitable for: Not suitable for cutting wood, plastics, or non-ferrous metals such as aluminium or copper — different blade profiles and tooth geometries are needed for those materials. Not intended for use in reciprocating saws.
Fit the T118BF blade into your jigsaw's T-shank clamp and make sure it's locked fully before starting. Set your speed according to the material — lower speeds for stainless steel, mid-to-high for mild steel sheet. Let the blade reach speed before contacting the workpiece.
Keep the jigsaw base plate flat against the material throughout the cut to avoid blade wander and reduce vibration. If the blade starts to overheat or cut slower than expected, ease off the feed rate rather than pushing harder. A cutting lubricant or wax applied to the blade will extend its life noticeably on longer cuts through thicker steel.
Secure the metal workpiece firmly before starting — movement during cutting is the main cause of blade breakage and poor cut quality
Insert the T118BF blade into the T-shank clamp and confirm it is fully locked
Select an appropriate speed setting on the jigsaw — lower for stainless steel and thicker section, higher for thinner mild steel sheet
Start the jigsaw and allow the blade to reach full speed before contacting the material
Guide the cut with the base plate flat on the workpiece surface throughout
Apply light cutting lubricant to the blade for longer cuts or tougher materials to reduce heat and preserve the edge
Allow the blade to cool briefly between cuts when working on extended runs through harder metals
Will the T118BF blade fit my jigsaw?
The T118BF uses a T-shank fitting, which is the standard shank type on the vast majority of modern jigsaws including Bosch, Makita, Dewalt, Ryobi and Milwaukee. If your jigsaw takes T-shank blades — and most do — it will fit. U-shank machines, which are older and less common, are not compatible.
Can I use these blades on stainless steel?
Yes. The HSS cutting edge handles stainless steel well. The key is to reduce your jigsaw speed and avoid forcing the blade — stainless work-hardens quickly if the cut slows and generates heat, which will blunt the teeth faster than the material itself would.
How do bi-metal blades last longer than standard jigsaw blades?
Standard blades are made from a single material and tend to compromise somewhere — either the body is brittle or the teeth are too soft. A bi-metal blade bonds a tough, flexible HCS body to a harder HSS cutting edge, so the teeth stay sharp longer and the blade itself resists flex cracking. In practice, you get significantly more cuts before the blade needs replacing.
The T118BF is a T-shank bi-metal jigsaw blade manufactured with a high carbon steel body and a high speed steel cutting edge, electron-beam welded together. This construction gives the blade its characteristic combination of shatter resistance and cutting durability. The HSS teeth retain hardness at elevated temperatures, which is particularly relevant when cutting ferrous metals where friction heat is unavoidable. Blade length is 76mm.
