Milwaukee 49-25-1521 Open-lok Carbide Multi-tool Blade 4 Pack

Product Description

The Milwaukee Electric Tool Corp 49-25-1521 is an Open-Lok carbide-teeth oscillating multi-tool blade designed for cutting across a wide range of materials in demanding trade applications. At 1-3/8 inches wide, it mounts to Open-Lok compatible oscillating tools and delivers durable cutting performance through wood, metal, plastic, and drywall. The carbide teeth construction is suited for extended use where standard bi-metal blades wear down quickly. This pack includes four blades, making it a practical choice for contractors and tradespeople who cycle through blades on busy job sites.

This blade is well suited for residential and light commercial work where multiple material types are encountered in a single job. Typical applications include flush cuts during rough-in work, trim removal, outlet cutouts in drywall, and cutting through mixed materials in remodel or demo scenarios. Electricians, plumbers, HVAC technicians, and general contractors all rely on oscillating blades of this type for access and trim work that other tools cannot reach.

Key Features

• Open-Lok mounting system for tool-free blade changes on compatible oscillating tools
• Carbide teeth construction for extended blade life versus standard bi-metal alternatives
• 1-3/8 inch blade width suited for flush and plunge cuts in tight spaces
• Cuts wood, metal, plastic, and drywall without blade swaps
• Sold as a 4-pack for job-site efficiency and reduced downtime

Compatibility

Designed for use with Open-Lok compatible oscillating multi-tool platforms. Verify Open-Lok interface compatibility with your specific oscillating tool model before installation.

Installation Notes

Blade changes should be performed with the oscillating tool powered off and unplugged or with the battery removed. Use the Open-Lok quick-change mechanism according to the tool manufacturer's instructions — no additional tools are typically required. Inspect the blade for damage before each use and replace immediately if carbide teeth are chipped or missing. Wear appropriate PPE including eye protection when operating oscillating tools.
