Diablo Jig Saw Blade 5 Pack DJT121AF5 3-5/8 Inch Bi-Metal (21 TPI, 1/16 to 1/8 Inch Metal Capacity, Precision Medium Metal Cutting)

High-Performance Medium Metal Jig Saw Precision

The Diablo DJT121AF5 3-5/8-inch 21 TPI Bi-Metal Jig Saw Blades are engineered for high-precision cutting in medium metal applications ranging from 1/16-inch to 1/8-inch thickness. Featuring an ultra-hardened cutting edge and an optimized bi-metal tooth configuration, these blades deliver five times the operational lifespan of standard cutting blades. The back-tapered body geometry reduces drag and vibration, while the Perma-SHIELD non-stick coating minimizes thermal buildup to ensure clean, consistent cuts in sheet metal, profiles, and pipe materials.

Best Used For:

• Sheet Metal Fabrication: Clean, high-tolerance cuts in thin-gauge ferrous and non-ferrous sheet metal materials.
• Metal Profile Trimming: Precise edge finishing for industrial metal profiles and lightweight tubing applications.
• HVAC Installation: Efficient cutting of pipes and metallic ducting requiring rapid, accurate plunge-cut entry.

Key Performance & Safety Features

• Bi-Metal Construction: High-speed steel teeth bonded to a flexible steel body for maximum impact resistance and durability.
• Perma-SHIELD Coating: Specialized non-stick thermal barrier that resists heat accumulation, gumming, and oxidation.
• Back Taper Geometry: Engineered blade body reduces friction during the stroke, promoting faster cut speeds and cleaner finishes.
• Fast Plunge Tip: Geometry designed to initiate plunge cuts quickly, eliminating the need for pre-drilled pilot holes.
• Universal T-Shank: Standardized shank configuration ensures secure fitment across all major corded and cordless jig saw platforms.

What's Included

• (5) 3-5/8 Inch 21 TPI Bi-Metal Jig Saw Blades for Medium Metal

Technical Specifications

Pro-Tip: Use a low stroke-per-minute (SPM) setting on your jig saw when cutting metal to prevent excessive heat buildup, which can prematurely dull the blade teeth.
