Diablo Jig Saw Blade DJT144DHM 4 Inch T Shank Carbide Teeth (5/7 Variable TPI Perma SHIELD Melt Free Composite Decking Fiber Cement Cutting)

Diablo DJT144DHM 4-Inch 5/7 TPI Carbide T-Shank Composite Decking Jig Saw Blade

The Diablo DJT144DHM is a 4-inch T-shank jig saw blade engineered with progressive 5/7 variable TPI carbide teeth for melt-free cutting in composite decking, fiber cement, and dense synthetic trim. Manufactured in Switzerland with TiCo Hi-Density carbide tips that deliver 50 times longer cutting life than standard bi-metal blades, this high-performance blade features a non-stick Perma-SHIELD coating that dissipates friction heat. Built for professional deck builders and carpenters using corded or cordless T-shank jig saws, its aggressive tooth geometry prevents plastic thermal gumming while cutting precise notches around deck posts and exterior fascia boards.

Best Used For:

• Composite Decking Post Notching & Trimming: Executing clean, melt-free curved and straight cuts in capped composite boards, PVC decking, and synthetic timber without plastic melting or blade gumming.
• Fiber Cement Board & Exterior Trim Siding: Slicing abrasive fiber cement wall panels and composite trim boards with minimal dust buildup and zero tooth dulling.
• Plaster & Dense Synthetic Material Cutting: Making plunge and relief cuts through architectural plaster, PVC sheet goods, and glass-filled polymers without edge chipping.

Key Performance & Safety Features

• 50X Extended Life TiCo Carbide: High-density titanium cobalt carbide teeth withstand intense abrasive wear in composite polymers and fiber cement.
• Perma-SHIELD Non-Stick Thermal Barrier: Proprietary fluoropolymer coating protects against friction heat buildup, material pitch, and blade gumming.
• Melt-Free Variable 5/7 TPI Tooth Geometry: Dual-pitch tooth design clears synthetic plastic shavings rapidly to prevent heat buildup and edge re-welding.
• Universal T-Shank Interface Connection: Industry-standard T-shank design ensures maximum tangential power transfer in all corded and cordless jig saws.
• Extreme Impact-Resistant Tip Bonding: Advanced tri-metal brazing secures carbide tooth tips against harsh lateral deflection and mechanical shock.
• Precise 4-Inch Working Reach Profile: 101-6/10 mm total body height provides optimal clearance for single-pass cuts in standard deck board thicknesses.

Technical Specifications

Pro-Tip: Set your jig saw pendulum orbital action to zero or setting 1 when cutting synthetic composite decking to ensure clean cut edges and prevent surface burring along the cut line.
