Calling all contractors, DIY warriors, and demolition fans! This is a serious bulk pack of IRWIN reciprocating saw blades. You get a whole box of 50 blades, so you'll be set for a long, long time. These are 6 inches long with a 14-teeth-per-inch (TPI) configuration. That 14 TPI makes them super versatile – great for cutting through wood, plastics, and even some thinner metals. They fit any standard reciprocating saw (Sawzall, etc.). They're made right here in the USA by IRWIN, a trusted name in professional tools. The model number is 372614BB. Having a big box like this means you can just grab a fresh blade whenever one gets dull, no more running to the store mid-project. Perfect for big renovation jobs, construction sites, or just having a ready supply in your workshop. Blades are consumables, they wear out, so buying in bulk like this saves you money in the long run. The pack is brand new and sealed. If you use your recip saw a lot, this is a no-brainer purchase to keep your tool cutting strong and smooth.
