Maximum Durability for Precision Metal Cutting

The Diablo DJT121AF5 3-5/8" 21 TPI Bi-Metal Jig Saw Blades are engineered to redefine performance in medium metal cutting applications. Designed specifically for materials ranging from 1/16-inch to 1/8-inch in thickness, these blades feature an ultra-hardened cutting edge that delivers up to five times the life of standard blades. Whether you are cutting sheet metal, pipes, or profiles, the optimized bi-metal tooth design ensures long-lasting sharpness and durability, making this 5-pack an essential addition to any professional toolbox or DIY workshop. 

Innovation meets efficiency with Diablo's advanced blade geometry. A unique back taper body design promotes fast, clean cuts by reducing drag, while the Perma-SHIELD® non-stick coating minimizes heat build-up and protects against pitch and corrosion. The blades also feature a fast plunge tip design, allowing for quicker and easier plunging without the need for a pilot hole. Equipped with a universal T-shank, these blades offer maximum performance and a secure fit for all combo and most U-shank cordless and corded jig saws on the market.

Key Features

  • Extended Lifespan: Ultra-hardened cutting edge delivers up to 5X longer life than standard bi-metal blades.
  • Optimized for Metal: Specifically designed for cutting medium metals ranging from 1/16 in. to 1/8 in. thickness.
  • Friction Reduction: Perma-SHIELD® non-stick coating resists heat build-up and protects against gumming and corrosion.
  • Precision Design: Back taper body allows for faster, cleaner cuts with less vibration.
  • Fast Plunging: Specialized tip design enables quicker and easier plunge cuts.
  • Universal Compatibility: T-shank design fits all combo and most U-shank cordless and corded jig saws.

Pro-Tip: When cutting metal with a jig saw, turn off the orbital action (set it to 0). Orbital action is great for wood but can cause metal-cutting blades to bounce, chatter, and break teeth prematurely. For the longest blade life and smoothest cut, use a slow to medium speed and apply a small amount of cutting lubricant to the cut line.

Good Quality, Easy to Install
Size: 1 Count (Pack of 1)
Good product, easy to install, but make sure to locate the direction arrow for proper installation. This one didn't have a very clear arrow but figured it out quickly and the install was done in seconds. I recommend this product.

DIY - Save $$
Size: 1 Count (Pack of 1)
Comparable item dealers provide, but if you can DIY, you’ll save $40-50 bucks installation. Helpful hint, before installing, take a market and put the date and mileage of the end of the filter. Unless you drive a lot, the filters generally last a year.
