BoneHead Corner Finishers are one of the two most commonly used automatic tools (along with flat finishers). They accomplish the goal of applying both the bed coat and the finishing coat over both sides of an inside corner.

The Only One-Piece Angle Head Frames in the Industry
Drywall Master Corner Finishers (aka Angle Heads) are the only corner finishers in the industry that are a one-piece design, machined from a solid block of stainless steel. This ensures a tighter tolerance, and ensures that we are able to hold the smallest gaps between the frames and the body in the industry. This ensures a no-leak design.

The main body is machined from solid billet aluminum, extra thick center clips, and military- grade stainless steel to ensure longevity. Our 3” and 3.5” corner finishers come with a center spring that adds even pressure to the frames, reducing twisting of the frames and thus ensuring longevity and a better overall finish.
