Bosch OSM114K 1-1/4 Inch StarlockMax Oscillating Knife Blade High Carbon Steel for Sealant Removal

Unrivaled Torque and Precision: Bosch StarlockMax® 1-1/4" Oscillating Knife Blade

Tackle the most demanding professional sealant removal tasks with the Bosch OSM114K StarlockMax® Oscillating Multi-Tool Knife Blade. Specifically engineered for extreme-duty applications, this 1-1/4 inch high-carbon steel blade features a precision-ground rectangular cutting edge designed to slice through tough sealants, silicone, and soft materials with surgical accuracy. The Swiss-made construction ensures long-lasting sharp edges, making it the premier choice for automotive glass repair, expansion joint maintenance, and heavy-duty window restoration where standard blades fail to perform.

The revolutionary StarlockMax® interface offers a three-dimensional connection between the tool and the accessory, providing a completely integrated system that handles higher torque than traditional flat interfaces. By utilizing this 3D shape, the OSM114K reduces vibration and maximizes power transfer, allowing you to work more efficiently while maintaining total control over the cutting path. Part of the Bosch heritage of innovation—alongside SDS-plus® and SDS-max®—the Starlock® system is the new professional standard for those who require the highest level of performance from their oscillating multi-tools.

Pro-Tip: To maximize the life of your knife blade when removing expansive sealants, apply a light lubricant (like soapy water) to the blade surface. This reduces friction and prevents "gumming" from the heated sealant, allowing the oscillating motion to slice through the material like butter.
