Introducing the Bosch 3-3/4 in. L X 3.75 in. W 120 Grit Aluminum Oxide Detail Sanding Triangle in a 25-pack—crafted for precise, controlled detail work on wood projects. This compact triangle is built to reach tight corners, inside curves, and molded profiles where flat sheets can’t touch, giving you cleaner edges and finer results with less effort.
Why this detail sanding triangle excels for wood
With a thoughtful triangle design and a comfortable footprint, you can swap between narrow points for acute inside corners and a broad edge for flat surfaces. The 3-3/4" length and 3.75" width strike a balance between maneuverability and material removal, so you can shape trim, cabinetry, and furniture components with confidence.
Medium 120 grit for refined prep and finishing
The 120 grit aluminum oxide abrasive strikes the right middle ground: it removes tool marks efficiently while leaving a smooth, ready-to-finish surface. It’s ideal for prepping wood before stain, sealants, or topcoats, as well as for light refinishing touches on existing pieces.
Durable abrasive for reliable performance
Aluminum oxide offers solid edge retention and resistance to loading, so these detail triangles maintain consistent cut over multiple passes without clogging, even on light-ended jobs or softwoods. They’re designed for dry sanding, delivering predictable results in a variety of shop conditions.
Value-packed packaging for busy workshops
Each box contains 25 detail sanding triangles, ensuring you have ample material on hand for ongoing projects, repairs, or shared shop usage. Perfect for kitchen renovations, furniture upgrades, or trim work where precise sanding makes a visible difference.
Designed to complement Bosch sanding systems
As part of Bosch’s power sanding accessories lineup, these detail triangles are optimized to work seamlessly with Bosch sanders and compatible handheld systems, helping you achieve professional-grade finishes with steady control and less fatigue.
Practical tips for best results
- Apply light, even pressure and let the abrasive do the work to avoid gouges.
- Dust between passes to clearly monitor progress and ensure a uniform finish.
- Use the triangle’s narrow points for interior corners and switch to the flat edge for larger flat surfaces.
- Store in the boxed packaging to keep edges organized and ready for your next project.
Whether you’re detailing cabinet doors, smoothing curved rails, or preparing trim for a flawless stain, the Bosch 120 Grit Aluminum Oxide Detail Sanding Triangle delivers consistent, controllable results that help you finish projects with professional precision.
