The Diablo 5-3/8" x 50-Teeth Saw Blade for Aluminum is a precision-engineered non-ferrous metal cutting blade built to deliver fast, accurate cuts in aluminum, copper, brass, plastic, and fiberglass without bogging down a cordless saw's battery. Designed for trim saw applications requiring clean, burr-free finishes, this blade is a reliable solution for contractors and tradespeople cutting medium aluminum stock, sheet metal components, and non-ferrous materials on the job site.

Key Features

• TiCo Hi-Density carbide construction - engineered exclusively for aluminum applications to deliver extreme cutting life and clog-free performance in non-ferrous materials
• Triple Chip Grind (TCG) tooth geometry - produces clean, burr-free finishes that virtually eliminate rework, saving time on finish-critical aluminum cutting jobs
• Tri-Metal Shock Resistant Brazing - allows carbide tips to withstand extreme impact forces during metal cutting, maximizing overall blade durability and service life
• Advanced laser-cut thin kerf body (.061" kerf /.039" plate) - minimizes material removal and reduces cutting power demand, enabling effortless, fast cuts with cordless saws
• Laser-cut stabilizer vents - trap noise and vibration to keep the blade cool, reduce blade warp, and improve cut accuracy over extended use
• Non-stick Perma-Shield Coating - reduces gumming, rusting, and corrosion, protecting blade life when cutting aluminum and other materials prone to buildup
• 20mm arbor with three included bushings (1/2", 5/8", and 10mm) - fits a wide range of cordless saw brands including Milwaukee, Bosch, Panasonic, Makita, Skil, and DeWalt for broad tool compatibility
• -5 deg. hook angle - optimized for controlled, chip-free cutting in non-ferrous metals, reducing the risk of blade grab during aluminum cuts
• 14500 maximum RPM rating - supports safe, high-speed operation on compatible trim saws for efficient production cutting

Why This Product

• Purpose-built for cordless efficiency - the thin kerf design and TiCo Hi-Density carbide formula work together to reduce battery drain, making this blade a practical choice for cordless trim saw users cutting aluminum in the field
• Virtually eliminates rework - the TCG tooth design produces burr-free cuts in medium aluminum (3/32"-1/4" thickness), copper, brass, plastic, and fiberglass, reducing secondary finishing steps on precision applications
• Broad arbor compatibility in a single blade - the 20mm arbor plus three additional bushings (1/2", 5/8", and 10mm) allow one blade to fit Milwaukee, Bosch, Panasonic, Makita, Skil, and DeWalt saws without purchasing separate adapters
• Built for durability in demanding metal cutting environments - Tri-Metal Shock Resistant Brazing and Perma-Shield Coating protect the blade against impact, corrosion, and material gumming for a longer service life in aluminum cutting applications

Frequently Asked Questions

What saw brands and arbor sizes is this blade compatible with?

This blade fits saws with 20mm, 1/2", 5/8", and 10mm arbors. Specific compatible brands include Milwaukee (20mm and 10mm arbors), Bosch (20mm arbor), Panasonic (20mm arbor), Makita (5/8" arbor), Skil (5/8" and 1/2" arbors), and DeWalt (10mm arbor). Three additional bushings are included in the package to accommodate all four arbor sizes.

What materials can this blade cut?

This blade is designed for cutting medium aluminum (3/32"-1/4" thickness), copper, brass, plastic, and fiberglass. It is optimized for non-ferrous metal cutting applications and is not intended for ferrous metals or wood.

What is the maximum safe operating speed for this blade?

This blade is rated to a maximum of 14500 RPM. Always verify that your saw's operating speed does not exceed this rating before use to ensure safe operation.

What makes the Triple Chip Grind (TCG) tooth design beneficial for aluminum cutting?

The Triple Chip Grind (TCG) tooth geometry is specifically designed to produce clean, burr-free finishes in aluminum and other non-ferrous materials. This virtually eliminates the need for secondary rework or deburring after cuts, improving efficiency and finish quality on aluminum cutting jobs.
