T-shank bi-metal jigsaw blades in a 3-pack, ground specifically for cutting thin metal under 1\/8 in. (mild steel sheet, aluminum sheet, copper, thin tubing). 24 TPI milled-tooth wavy-set profile gives a clean finish on sheet metal without snagging or tearing. Bi-metal construction with 8% cobalt high-speed-steel teeth flash-welded to a flexible spring-steel body — teeth stay sharp under heat, body bends instead of snapping when the cut binds.\u003c\/p\u003e\n\u003ch3\u003ePack Contents\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 blades per pack\u003c\/strong\u003e — bulk-pack for production use; each blade individually replaceable in the jigsaw without unpacking the rest\u003c\/li\u003e\n\u003cli\u003eEach blade: 3 in. total length, 24 TPI, T-shank, .035 in. body thickness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat These Are For\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThin sheet metal cutting (under 1\/8 in. \/ ~3 mm)\u003c\/strong\u003e — mild steel sheet, aluminum sheet, copper, brass, thin-walled tubing. 24 TPI is fine enough that at least 3 teeth are engaged with the work at any time, which is the cutoff for chatter-free cuts in sheet metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHVAC ductwork:\u003c\/strong\u003e trimming galvanized duct, sheet metal supply collars, plenum tabs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal trim cutting:\u003c\/strong\u003e drip edge, J-channel, flashing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto and equipment repair:\u003c\/strong\u003e trimming body panels, patch metal, small-tube cutting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight fabrication:\u003c\/strong\u003e trim cuts on punched plate, slot extension, hole-extension cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat These Are NOT For\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThick metal (1\/8 in. and up):\u003c\/strong\u003e use a coarser blade (10-14 TPI). 24 TPI in thick metal will glaze and burn out fast.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWood:\u003c\/strong\u003e way too fine.

Full speed throws sparks and burns the temper out of the blade.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLubricate the cut.\u003c\/strong\u003e A drop of cutting oil or even WD-40 on the blade extends life dramatically when cutting metal. Wax-based cutting compounds (Tap Magic, Trim-Tap) work even better for non-ferrous metals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLet the blade do the work.\u003c\/strong\u003e Don't push hard — the blade cuts on the upstroke (T-shanks point downward in the saw). Pressing into the cut bends the blade and breaks teeth.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eClamp the work piece.\u003c\/strong\u003e Sheet metal vibrates more than wood; an unclamped sheet will chatter, ruin the cut, and dull the blade in seconds. Use a backing board (scrap wood) under thin sheets to dampen vibration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWatch for the “3 teeth in the work” rule.\u003c\/strong\u003e 24 TPI = teeth ~0.04 in. apart — perfect for metal down to about 16-gauge. On thinner stock (24-gauge and below), the teeth can hook the edge instead of cutting. If you're cutting metal that thin, drop to a 32 TPI blade or use shears.\u003c\/p\u003e\n\u003ch3\u003eWhat’s in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e3 Ivy Classic 28589 bi-metal T-shank jigsaw blades, 3 in. \/ 24 TPI, in retail card pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatible Accessories — Sold Separately\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCutting oil or wax-based lubricant for blade life on metal cuts\u003c\/li\u003e\n\u003cli\u003eCoarser TPI Ivy Classic jigsaw blades (6, 10, 14 TPI) for wood and thicker metal\u003c\/li\u003e\n\u003cli\u003eCarbide-grit jigsaw blades for hardened or stainless plate\u003c\/li\u003e\n\u003cli\u003eSheet-metal hand snips for cuts too small or thin for the jigsaw\u003c\/li\u003e\n\u003cli\u003eReplacement T-shank wood blades for the wood cutting on the same project\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eStop by Garoppo’s to pick one up, or schedule local delivery within our service area.\u003c\/p\u003e","brand":"Ivy Classic","offers":[{"title":"3\" \/ 24","offer_id":54327516791076,"sku":"41478","price":6.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/5322\/9860\/files\/ivy-classic-jigsaw-blades-3-inch-24-tpi-bi-metal-t-shank-3-pack_eb4c02e5-7147-4cb2-9cfb-3b3eef620517.png?v=1780596534","url":"https:\/\/garoppos.com\/products\/ivy-classic-jigsaw-blades-3-in-24-tpi-bi-metal-t-shank","provider":"Garoppo's Stone \u0026 Garden Center and Feed \u0026 Pet Supply","version":"1.0","type":"link"}
