 MAKITA A-85721 B-Type No.B-21 Jigsaw Blade 100 mm 12 TPI (Pack of 5) for Aluminum and Plastic Cutting
The MAKITA A-85721 Model B-21 jigsaw blade is a standard T-shank blade designed for cutting materials that require precision and minimized burr formation in metal, or reduced melting/warping in plastic. Made of high-speed steel (HSS) for durability against friction and heat generated when cutting metals and plastics. Featuring a relatively fine tooth count of 12 TPI with precision ground teeth, it produces clean and accurate cuts in low to medium-thickness materials. This blade is especially suitable for installers who need to cut aluminum sheets or PVC pipes/sheets where neat joints are required.

Specifications
- Clean Plastic Cuts: 12  TPI helps reduce heat buildup and melting of plastics (such as PVC)
- Smooth Cut Edge: Ground teeth design provides a smoother cut edge than milled tooth blades
- HSS Material: Durable and provides excellent sharpness retention for cutting non-ferrous metals
- Versatile for Installers: Ideal for tasks requiring cuts in non-wood composite materials such as aluminum frames, acrylic sheets, and plastic pipes
