Robert Bosch Tool Group SDTR122C 120 Grit Triangle Sanding Sheets

Product Description

The ROBERT BOSCH TOOL GROUP SDTR122C is a 25-pack of triangular abrasive sanding sheets designed for use with detail sanders. Each triangle measures 3.75 inches and carries a 120-grit abrasive surface, making it suited for medium-fine material removal and surface prep. The hook-and-loop attachment system secures the sheet directly to the sander pad without adhesive or clips. These sheets are intended for finish-oriented sanding work where flat-pad sanders cannot reach. Carpenters, finish contractors, and woodworkers are the primary installers and users of this consumable.

These abrasive triangles are designed for sanding plywood, hardwoods, and softwoods in residential and light commercial finish work. The triangular geometry allows the pointed tip to access tight corners, coves, window trim, door casings, and other confined areas where rectangular or disc pads cannot make full contact. They are a direct consumable replacement for detail sander applications requiring 120-grit material removal without aggressive stock reduction.

Key Features

• 120-grit abrasive surface for medium-fine sanding and surface prep
• Triangular shape reaches corners and tight spaces inaccessible to flat pads
• Hook-and-loop attachment for fast, tool-free sheet changes
• Suitable for plywood, hardwoods, and softwoods
• 25 sheets per pack for extended job-site use

Compatibility

Designed for use with detail sanders equipped with a hook-and-loop triangular pad accepting 3.75-inch abrasive triangles.

Installation Notes

Disconnect the sander from its power source before changing abrasive sheets. Align the triangle with the pad edges and press firmly to seat the hook-and-loop backing fully before operating. Inspect each sheet before use and discard any sheet showing tears, loading, or glazing that would reduce cut rate. Worn or clogged sheets should be replaced promptly to avoid heat buildup and surface damage.
