50-Degree Pie Cut Corner Hinge for Overlay Corner Cabinets

The Hettich Intermat pie cut corner hinge is a concealed self-close hinge engineered for the tight geometry of pie cut corner cabinets, where a standard 110-degree hinge cannot swing freely. Its 50-degree opening keeps each door panel inside the corner envelope so the two doors clear each other and the adjacent cabinet fronts as they swing.

Key Features

• 50-degree opening angle is the geometry pie cut corner cabinets require to avoid door-to-door collision.
• Self-close spring pulls each door panel shut over the last few degrees of travel.
• Overlay arm positions the door panel to cover the cabinet side or frame edge in a standard overlay configuration.
• Screw-on mounting fastens the hinge directly to the cabinet, no separate base plate required.
• Works on both face-frame and frameless cabinets, giving it a place in traditional and modern kitchen builds.
• 35mm cup bores into a standard hole with a 45mm bore pattern, compatible with existing CNC setups.

Built for the Corner Cabinet That Standard Hinges Cannot Serve

A pie cut corner cabinet splits its interior with angled door panels that radiate outward from the corner. When open, each panel swings through an arc bounded by the adjacent cabinet. A 110-degree hinge would drive the door panel straight into the neighboring face frame or door. The 50-degree opening on this hinge is the engineered answer: each panel travels only as far as the geometry allows before the spring draws it closed again. This is not a restricted angle to work around; it is the correct angle for this specific application.

The 35mm cup bores into the back of each door panel at the standard depth. Because this is a screw-on hinge, it fastens directly to the cabinet side or stile without a separate base plate, which simplifies the install and reduces parts count on a corner build that already demands careful fitting.

Steel Construction in a Nickel Finish

The hinge is steel with a nickel finish. In a corner cabinet, hinges are largely out of sight behind the door panels, so the finish serves continuity with other visible hardware in the kitchen rather than decorative prominence. The steel construction handles the repeated self-close cycle across both door panels without fatigue, which matters on a corner cabinet that sees constant daily use as a rotating base.

The Right Fit for Corner Builds

This hinge is the practical choice for cabinetmakers and contractors building or retrofitting pie cut corner base or wall cabinets on face-frame or frameless boxes. It suits shops that already run a 35mm boring setup and want a corner hinge that drops into the same workflow. Door thickness should fall between 14mm and 21mm. For doors outside that range, a different hinge is needed. If the project calls for a cushioned, damped close on the corner doors rather than a spring pull, confirm whether a soft-close version of this series is available for the application.

Common Questions

Corner Doors That Close on Their Own, Every Time

When the project calls for pie cut corner doors that close reliably without slamming into the neighboring cabinet, this Intermat hinge handles the geometry and the self-close spring handles the rest.
