INGCO 5-Piece HSS Metal-Cutting Jigsaw Blade Set (12 TPI, 50mm Working Length)
Stop ruining your woodworking blades and stalling your jigsaw on metal plates. The INGCO JSBT118B “Basic for Metal” Jigsaw Blade Set is an essential metal-processing accessory engineered to slice cleanly through structural steel sheets, iron panels, and non-ferrous metal strips. Forged from ultra-hard, wear-resistant High-Speed Steel, these blades dissipate intense friction heat rapidly, ensuring that metal fabricators, window grill installers, and automotive modifiers get smooth, burr-free cuts across every single tracking line.
High-Speed Steel Metallurgy & Tooth Architecture
Premium Hardened High-Speed Steel (HSS): Fully forged from premium, industrial-grade HSS alloy. Unlike standard high-carbon steel blades that dull or melt instantly when friction hits, HSS maintains its rigid cutting edge hardness even under high thermal stress, ensuring a prolonged operational lifespan.
Milled, Wavy-Set Tooth Geometry: The fine teeth are precision-milled and arranged in an alternating wavy-set alignment. This structural arrangement allows the blade to create a clean, slightly wider channel than the blade body, completely eliminating material binding, pinching, and aggressive tool kickbacks.
High-Density 12 TPI Matrix: Features an optimized density of 12 Teeth Per Inch. This spacing ensures the perfect balance between cutting speed and structural control, keeping at least 3 teeth engaged in the material simultaneously to prevent blade snagging or chatter.
Sizing Optimization & Universal Fitment
Calibrated for 2.5mm to 6mm Sheet Metals: Engineered precisely to process medium-to-thick metal stocks. It glides through mild steel channels, galvanized roof frames, iron angles, and thick aluminum panels seamlessly.
50mm Effective Tooth Length: Provides a compact, highly rigid working stroke length. The 50mm profile minimizes vertical blade flexing, allowing you to trace tight curves, geometric cutouts, and straight lines without the blade wandering out of alignment.
Universal T-Shank Base: Features a standard single-lug T-shank profile that locks automatically into all modern quick-release jigsaw clamps across all professional power tool ecosystems.

Best Use Cases
Window Grill & Gate Customization: The absolute go-to accessory for metal fabricators cutting internal design layouts out of medium-gauge mild steel window sheets and iron panel frames.
Automotive Body Customization & Repair: Perfect for car mechanics and detailing technicians cutting custom structural lines into vehicle body sheets, silencer plates, or floorboards.
Electrical Panel Box Modification: Ideal for commercial electricians cutting custom entry pathways, wide conduit channels, or rectangular switch slots directly into thick sheet metal distribution boxes.
HVAC Ducting & Structural Bracket Trimming: Excellent for ventilation technicians cleanly adjusting thick galvanized structural mounting tracks and heavy framing brackets on site.
TK Pro Tip: Cutting metal with a jigsaw generates intense friction heat at the tooth tip line. To dramatically multiply the lifespan of your HSS blades and get an incredibly glassy, burr-free edge, always apply a few drops of cutting oil, machine lubricant, or even multi-purpose spray along your marked cut line before tracing! Additionally, turn off your jigsaw’s orbital action completely (set the orbital selector switch to 0). Orbital action is great for wood but causes jigsaw blades to bounce violently against steel, which can dull or chip the fine 12 TPI teeth early. Keep the base plate pressed rock-solid and flat against the sheet metal, use steady forward pressure, and let the HSS edge melt through the metal naturally!
