HSS jigsaw blades for cutting thin sheet metals, aluminium, mild steel and plastic. Milled and side set teeth give a quick, fairly rough cut. High Speed Steel body handles the heat generated when cutting metal without losing its edge.
The T127D HSS metal jigsaw blades are designed for one job: cutting metal cleanly and quickly without burning through blades every five minutes. High Speed Steel holds its hardness at elevated temperatures, which matters when you’re pushing through mild steel, aluminium sheet or plastic where friction builds fast. These are a genuine working blade, not a weekend DIY throw-in.
At 100mm in length with a T-shank fitting, they’ll seat straight into the vast majority of modern jigsaws on site. T-shank has been the standard for years now, so compatibility is rarely an issue.
Where T127D HSS Metal Jigsaw Blades Get Used
The milled and side set (MSS) tooth configuration is worth understanding. Milling the teeth produces a consistent, sharp edge, and the side set gives the blade a kerf wide enough to stop it binding in the cut. The trade-off is that the finish is fairly rough rather than fine. That’s entirely appropriate for most metal cutting tasks on site, where you’re trimming sheet steel, knocking out apertures in metal panels, or working through aluminium sections. If you need a mirror finish, you’re probably reaching for a different tool entirely.
HSS is the right steel grade for this application. Bi-metal blades get more attention, but HSS blades at this price point do the job well on thinner stock and are perfectly serviceable for regular use. The body stays stiff enough to track a line without wandering, which is the main frustration with cheaper blades on metal.
Pack Size and Value
These come in packs of five, which is a sensible working quantity. Metal cutting blades wear faster than wood blades given the material hardness, so having spares to hand is just practical. Buying in bulk across multiple packs keeps the cost per blade low, which adds up quickly if you’re running a team or doing regular fabrication work.
For contractors cutting thin sheet metals, aluminium extrusions, steel panels or plastic on site, the T127D HSS metal jigsaw blades are a straightforward, dependable choice that won’t slow the job down.
Pro Tip: Always run your jigsaw at a higher speed setting with no orbital action when cutting metal with HSS blades, slow orbital cuts generate uneven heat and will dull the teeth far sooner than a clean high-speed pass.
These blades are used wherever a jigsaw needs to cut through thin metal on site or in a workshop. Typical jobs include trimming mild steel sheet, cutting aluminium extrusions, shaping plastic panels, and making apertures in metal enclosures or trunking. They're common on roofing, cladding, fabrication and general maintenance work where sheet metal handling is part of the day.

Key Specifications
Blade length: 100mm
Blade material: High Speed Steel (HSS)
Tooth configuration: Milled and side set (MSS)
Shank type: T-shank
Pack quantity: 5 blades
Cut type: Quick, fairly rough cut
Not suitable for: Not suitable for cutting thick steel sections or hardened steel. The rough cut finish makes these blades unsuitable for applications requiring a clean or polished edge on visible metalwork.
Fit the blade into your jigsaw with the tool unplugged or battery removed. T-shank blades click straight in on tool-free chuck systems with no faffing around. Set the jigsaw to a high speed with orbital action turned off before cutting metal. Mark your cut line clearly and use a straight edge or guide where accuracy matters.
Keep steady, even forward pressure through the cut. Let the blade do the work rather than forcing the pace. On thin sheet, clamp the workpiece securely to stop it vibrating, as loose sheet metal rattles badly and produces a ragged edge. Replace the blade as soon as you notice it starting to drag or overheat rather than cutting clean.
Ensure the jigsaw is unplugged or the battery is removed before fitting the blade
Insert the T127D blade into the T-shank chuck until it clicks securely into place
Set the jigsaw to high speed with orbital action switched off
Clamp the metal workpiece firmly to prevent vibration during the cut
Mark your cut line clearly and position the blade just outside it
Begin the cut with steady, even forward pressure and let the blade speed do the work
Keep the jigsaw base plate flat on the material throughout the cut
Replace the blade if it starts to drag, overheat, or produce a noticeably rougher cut than expected
What thickness of metal can the T127D blade cut?
These blades are designed for thin sheet metals. As a general guide they work well up to around 3mm on mild steel and slightly more on softer materials like aluminium. For thicker stock you would need a heavier duty blade with a coarser TPI rating.
Will these blades fit my jigsaw?
Yes, in almost all cases. The T127D uses a T-shank fitting which is the universal standard adopted by Bosch, Makita, DeWalt, Milwaukee, Festool and most other brands. If you have an older jigsaw with a U-shank (bayonet) fitting, you would need to check compatibility before ordering.
Can I use these blades to cut plastic as well as metal?
Yes. HSS blades handle plastic sheet well and the milled side set tooth pattern cuts through it quickly. They are commonly used on PVC, acrylic and general plastic profiles on site. Avoid very thin or brittle plastics at high speed as the blade may chip the edges.
The T127D blade is manufactured from High Speed Steel, a tool steel alloy that retains its hardness at the elevated temperatures generated during metal cutting. Milled and side set teeth produce a wide kerf that resists binding while delivering a fast, aggressive cut. The T-shank profile conforms to the universal jigsaw standard, ensuring reliable fitment across modern machines without adapters.
