Milwaukee 49-25-1251 OPEN-LOK Titanium Charged Bi-Metal Thin-Metal Multi-Tool Blade, 1-1/8"

The Milwaukee 49-25-1251 OPEN-LOK Titanium Charged Bi-Metal Thin-Metal Multi-Tool Blade is a 1-1/8" oscillating multi-tool blade built for cutting thin metal quickly and cleanly. The blade combines a Bi-Metal body with a Titanium Charged coating to help it resist wear and hold a cutting edge through repeated use on thin-gauge metal materials. Its OPEN-LOK attachment design is engineered to mount directly to OPEN-LOK-compatible oscillating multi-tools, allowing for fast, secure, tool-free blade changes on the jobsite. This blade is sized for detail cutting and tight-radius work where a compact 1-1/8" profile is needed to navigate around obstructions.

Key Features

  • Trade Size: 1-1/8" blade width sized for maneuvering through tight cutting lines and detail work in thin metal.
  • Durable Construction: Bi-Metal body combines a flexible backing with a hardened cutting edge to withstand repeated flexing and impact during cutting.
  • Titanium Charged Coating: reduces friction and heat buildup during cutting, helping the blade stay sharper longer across thin metal cutting applications.
  • OPEN-LOK Attachment System: quick-change interface fits OPEN-LOK-enabled oscillating multi-tools for tool-free blade swaps and consistent, secure alignment.
  • Thin Metal Cutting Design: blade profile is matched to cutting thin-gauge metal cleanly, helping minimize burring and snagging during the cut.
  • Compact Profile: the 1-1/8" blade size is suited to detail cuts, tight corners, and confined work areas where a full-size blade will not fit.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Cutting Thin-Gauge Sheet Metal
  • Trimming Metal Flashing and Trim
  • Modifying Ductwork and Metal Enclosures
  • Remodeling and Renovation Cutting Tasks
  • General Metal Fabrication Touch-Ups

Milwaukee 49-25-1251 – Frequently Asked Questions

1) What materials is the Milwaukee OPEN-LOK 49-25-1251 multi-tool blade meant to cut?
Thin-gauge metal. It is built for sheet metal, metal flashing and trim, ductwork and metal enclosures, and general metal fabrication touch-ups. For wood, nail-embedded wood, or plastics you want a different blade profile.
2) Why choose a 1-1/8 inch multi-tool blade instead of a wider one for metal cutting?
The 1-1/8 inch width is a detail blade. It gets into tight corners, tight-radius cuts, and confined spaces where a full-width blade will not fit, and it tracks a tight cutting line better. A wider blade covers more material per stroke and is the better pick for long straight runs in sheet metal.
3) What is the difference between a bi-metal blade and a Titanium Charged bi-metal blade like the 49-25-1251?
Both have a bi-metal body, a flexible backing welded to a hardened cutting edge, which is what lets the blade flex without snapping. The 49-25-1251 adds a Titanium Charged coating that cuts friction and heat buildup, so the teeth hold an edge longer through repeated cuts in thin metal.
4) Can I use the 49-25-1251 blade for cutting out an electrical box opening in sheet metal duct or an enclosure?
Yes, that is squarely what it is for. Modifying ductwork and metal enclosures is a listed application, and the narrow 1-1/8 inch profile lets you plunge and follow a tight layout line inside a confined cavity. Keep it on thin-gauge material; it is not a blade for structural or thick stock.
5) What is the Milwaukee part number for the OPEN-LOK 1-1/8 inch thin-metal multi-tool blade?
Order it as Milwaukee 49-25-1251. It is the 1-1/8 inch OPEN-LOK Titanium Charged bi-metal thin-metal blade.
