Milwaukee 49-25-1231 OPEN-LOK 1-3/8″ Titanium Charged Bi-Metal Universal Fit Multi-Tool Blade

Milwaukee’s 49-25-1231 OPEN-LOK™ 1-3/8″ TITANIUM CHARGED™ Bi-Metal Oscillating Blade is built for fast, controlled plunge cuts across common jobsite materials without frequent blade swaps. The bi-metal construction uses premium high-speed steel teeth bonded to a flexible backing for durability, while Milwaukee’s titanium-charged coating increases wear resistance for a longer cutting life—up to 15x versus standard high-carbon steel blades in like applications. An OPEN-LOK reinforced anchor delivers a solid, universal fit to 100+ non-Starlock oscillating multi-tools and enables quick blade changes. The raised hub supports true flush cutting along floors, jambs, and trim, and the cut-away body helps clear chips for efficient plunge cuts.

Sized at 1-3/8″ cutting width with up to 2″ max plunge depth and 18 TPI, this multi-material blade handles wood, PVC, drywall, and wood-with-nails work. Clear, long-lasting laser etching keeps sizing and part ID readable after multiple cuts. A protective black-oxide finish helps fight corrosion between uses. Whether trimming casing, cutting drywall openings, notching pipe chases, or removing fastener-studded sections, this universal fit oscillating blade provides reliable control and service life in a single, everyday profile.

Why Customers Choose the Milwaukee OPEN-LOK 1-3/8″ Titanium Charged Bi-Metal Universal Fit Multi-Tool Blade

Crews pick this universal fit oscillating multi-tool blade because the titanium-charged bi-metal edge holds up when jobs shift from clean wood to wood with nails or drywall with hidden screws. The OPEN-LOK anchor locks solidly onto most non-Starlock tools, so blade swaps are fast and the interface doesn’t wobble during precise plunge cuts. A 1-3/8″ width gives good visibility and control around trim and flooring, while the 2″ plunge depth reaches through jambs and sheathing without overcutting. With durable laser markings and a corrosion-resistant finish, the blade stays readable and ready in the kit. For technicians who want consistent, repeatable results on mixed-material tasks, this Milwaukee blade provides the right mix of cut speed, accuracy, and service life.
