Plunge-Cut Track Saw. Model number KSBACS40TK. This is a battery-tool-specific blade — it's engineered around the reality that a cordless saw has finite runtime per charge, and every bit of unnecessary motor load cuts into that runtime.\u003c\/p\u003e\n      \u003cp\u003eThe 1.6 mm thin-kerf design is the core idea behind this blade. Removing less material per cut means the motor works less hard for every pass, which directly extends how many cuts you get from a single battery charge — a meaningful difference on a jobsite where swapping and recharging batteries costs real time. Forty carbide-tipped teeth on the 6-1\/2 in. plate keep the cut quality high despite the thinner kerf, so you're not trading battery efficiency for a rougher edge.\u003c\/p\u003e\n      \u003cp\u003eThe laser-cut steel body with anti-vibration slots addresses a problem specific to smaller, faster-spinning blades: at up to 7,000 RPM on a compact 6-1\/2 in. plate, vibration and chatter show up more readily than on a larger, slower blade. The relief slots cut into the body keep the plate quiet and stable through long rip cuts on plywood and sheet goods, which is exactly the kind of cutting the Adaptive Cutting System track saw setup is designed for.\u003c\/p\u003e\n      \u003cp\u003eThis blade is purpose-built for one saw: the Kreg 20V Ionic Drive 6-1\/2 in. Plunge-Cut Track Saw (KPTPS100A) and its battery-kit counterpart (KPTBPS100A). It is not compatible with Kreg's corded Adaptive Cutting System Plunge-Cut Track Saw — that saw uses a different blade in this same family. If you're not certain which track saw you own, check the model number before ordering a replacement blade.\u003c\/p\u003e\n      \u003cp\u003eWho should buy this: anyone running Kreg's cordless 6-1\/2 in. plunge-cut track saw who needs a replacement or spare blade. Ripping down plywood and sheet goods on a job where recharging isn't convenient is exactly the scenario this blade is engineered for.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eMatched to the Cordless Track Saw System\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"row\"\u003e\n        \u003cdiv class=\"img\"\u003e\n          \u003cimg src=\"https:\/\/www.kregtool.com\/dw\/image\/v2\/BDZM_PRD\/on\/demandware.static\/-\/Sites-master-kreg\/default\/dw7b9ec307\/images\/hi-res\/KSBACS40TK-Feature-02.jpg\" alt=\"Carbide teeth detail on the Kreg Adaptive Cutting System thin kerf blade\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis blade is built around the way Kreg's cordless track saw actually gets used — ripping sheet goods where battery runtime is a real constraint, not an afterthought.\u003c\/p\u003e\n          \u003cul\u003e\n          \u003cli\u003e40-tooth carbide grind for clean rips and crosscuts\u003c\/li\u003e\n          \u003cli\u003ePurpose-built for the Kreg 20V Ionic Drive 6-1\/2 in.
