Jigsaw blade for thin sheet metal, about 0.5–1.5 mm
Updated: 22 October 2026
Trunking, a tray or the skin of a small cabinet is often under 1.5 mm, and a general metal blade grabs it. A jigsaw blade for thin sheet metal in that band is a fine, wavy-set tooth, with the sheet clamped so it cannot flap. This page stays on about 0.5–1.5 mm mild sheet. Thicker brackets, aluminium and stainless are named only so you can leave them. The nine packs and their prices are in the [jigsaw blades metal comparison](/hub/saw-accessories/jigsaw-blades-metal).

What counts as thin sheet for a jigsaw
Here, thin mild sheet means about 0.5–1.5 mm: trunking, a tray, a cabinet side. Bosch Professional’s UK page for the T118G puts non-perforated sheet in that band, with a wavy-set milled tooth at 0.7 mm pitch. More teeth in the cut means less snatch, in the region of 24–32 TPI. Use the thickness band printed for the pack you buy.
The T118G-class packs in this comparison
Bosch’s T118G, B0009U7B2Q, is £5.25 and 4.5 from 216: 0.5–1.5 mm, wavy-set and milled, part 2608631012. Bosch Professional lists HSS, 92 mm and a T-shank. The Amazon row does not print HSS. UK reviews describe clean thin cuts and teeth that go quickly on thicker sheet. Eclipse’s EPT118G is £4.95, 4.6 from 67, 32 TPI HSS up to 1.5 mm. Shank and length are not on that row. Spear & Jackson’s T-shank and 75 mm belong to the maker table. Seat the tang before you rely on either pack.
Blades that are one step too coarse
T118A, about 1–3 mm, is coarser than a 32 TPI T118G. JMD’s 30-piece is 21 TPI. On floppy 1 mm trunking that tooth snatches. T118B, about 2.5–6 mm, will hook trunking. The TopsTools 25-pack states about 3–6 mm at £11.99. The 15-piece at £7.99 includes a T118G among coarser codes, which is a mixed-thickness drawer, not a finer blade than the two five-packs. Other jobs are on best jigsaw blades for metal.
Keep the sheet still
Set the pendulum to 0, clamp the sheet, and if it can flap put scrap wood behind it and cut both together. A light feed and a film of oil keep the small tooth from turning blue. For a hole, drill a starter and enter with the shoe flat. Do not plunge into 1 mm steel. The full sequence is on how to cut metal with a jigsaw.
Thin stainless and thicker sheet are different blades
These HSS packs are not stainless blades. Thin stainless wants a bi-metal the maker rates for it, such as a T118GFS, outside these nine ASINs. That choice is on HSS vs bi-metal jigsaw blades. Starrett’s BU224, £3.89, is 24 TPI bi-metal, 50 mm, stated 1.6–3.2 mm. It suits a shallow cut-out, and it is the wrong first pick for 0.5–1 mm trunking.
Common questions
What jigsaw blade do I need for thin sheet metal?
For about 0.5–1.5 mm mild sheet, use a fine wavy-set blade in the T118G class and clamp the sheet. In this comparison that is Bosch’s five-pack at £5.25 or Eclipse’s EPT118G at £4.95. Check the shank. A coarse “metal” blade will snatch trunking even if the label is honest about cutting steel.
Is a T118G the right blade for 1 mm steel?
Yes for mild steel around 1 mm, which sits inside Bosch’s 0.5–1.5 mm band and inside Eclipse’s “up to 1.5 mm” line. Bosch’s UK page also states a 0.7 mm tooth spacing and 92 mm overall. UK reviews still describe rapid wear if the sheet is thicker than the band, so measure before you assume every offcut is 1 mm.
Can I use a T118A or T118B on trunking?
A T118A is the overlap at the thick end, about 1–3 mm, and it is coarser than a 32 TPI T118G. It is a poor default for 1 mm trunking. A T118B, about 2.5–6 mm, is the wrong tooth and will hook thin sheet. Keep the T118B pack for the thicker job it was sold for.
How many teeth do I want in thin metal?
A high count, in the region of 24–32 TPI, so several teeth stay in the cut and the sheet vibrates less. Eclipse states 32 TPI. Machine Mart groups that very fine range with thin sheet. A 14-tooth medium blade is for thicker plate, not for a tray.
Will a jigsaw tear 0.5 mm sheet?
It will if the tooth is coarse or the sheet can flap. A T118G-class blade, orbital action off, and a wood backing under a drumming panel are what keep 0.5 mm sheet from tearing. Oil on the line and a light feed matter as well. The full steps are on the how-to page, including a drilled hole rather than a plunge.
Do I need a bi-metal blade for ordinary mild sheet this thin?
No. Stiff HSS in the T118G class is the ordinary buy for straight mild sheet at 0.5–1.5 mm. Bi-metal matters when the blade must flex or the metal is stainless. Starrett’s bi-metal pack starts at a stated 1.6 mm and is 50 mm long, so it is not the trunking blade.
What about thin stainless steel?
Do not use these HSS packs as the stainless blade. Thin stainless still wants a bi-metal rated for it, such as a T118GFS for about 0.5–1.5 mm, and that code is not in this nine-pack table. The same thickness in mild steel and in stainless is not the same tooth.
