Buddy Tools D-Wing Corner Trowel – 7.5-inch Stainless Steel Inside Corner Tool for Smooth Finishes

Meet the D-Wing Corner Trowel

The Buddy Tools D-Wing Corner Trowel is built to tackle inside drywall corners with precision and ease. Its 7.5-inch blade works in tandem with a 1.5-inch wing to smooth the joint while feathering the adjacent surface, helping reduce gouges, ridges, voids, and the need for heavy sanding. The result is a clean, professional look across the corner bead and the nearby plane.

Smart design you can rely on

This tool uses a one-piece construction: a rigid stainless-steel blade fused to a polymer over-mold. The assembly is rust resistant, and there are no rivets or hardware that can clog with compound. The blend of metal and polymer cleans quickly and maintains its shape through repeated use.

Coverage that speeds finishing

Compared with compact corner knives, the D-Wing is wider, so it covers more of the joint in a single pass. This helps you apply mud more efficiently and reduces the need to reposition the tool mid-work, saving time on each corner.

Bi-directional control for steady results

The comfortable polymer grip rotates in your hand, letting you switch direction quickly without changing your grip. This enables consistent pressure and helps you maintain a clean edge on both sides of the corner.

How to use for best results

Start with mud on the wall using your chosen drywall knife. Move the D-Wing up or down the corner, then wipe clean as you go. After the first coat dries, repeat on the second side for a balanced finish.
