The MILWAUKEE TOOL 48-22-9109 is a 10-pack of snap knife replacement blades designed for precision cutting tasks. Manufactured from carbon steel with a sharp point, these blades deliver clean, consistent cuts across a wide range of materials. Each blade measures 4.875 inches in overall length and is finished in black. The pack weighs 0.08 pounds, making it easy to stock in a service vehicle or job-site toolbox. These blades are intended for use with compatible Milwaukee snap knives and are suited to tradespeople who depend on a sharp edge throughout the workday.
Snap knife blades see regular use across HVAC, electrical, plumbing, and general construction trades. Common applications include cutting insulation, sheathing, tape, gasket material, and vapor barriers. When a blade segment dulls, the leading section snaps off at the scored break line to expose a fresh edge, extending the usable life of the blade set. This 10-pack format suits contractors and service technicians who cycle through blades frequently on active job sites or during scheduled maintenance work.
Designed as OEM-style replacement snap knife blades compatible with Milwaukee Tool snap knife handles that accept this blade profile. Confirm handle model compatibility before ordering.
Snap knife blade replacement is typically performed by any trade professional as part of routine tool maintenance. Before removing or installing a blade, retract the blade carrier fully and keep fingers clear of the exposed edge. Dispose of used snap-off segments in a puncture-resistant sharps container to comply with job-site safety requirements. No special tools are required for blade changes.
