35mm Carbide Tipped Hinge Boring Bit — 57mm Length

The BHB0035 is a carbide tipped hinge boring bit — 35mm diameter, 57mm overall length — for boring the European-style cup hinge mortise in cabinet door faces. European cup hinges (Blum Clip-Top, Grass Tiomos, Salice, and compatible brands) require a precise 35mm diameter flat-bottom hole bored into the back face of the door at a specified distance from the door edge. The BHB0035 bores this mortise on a CNC boring machine, bench-top hinge boring press, or single-spindle hinge boring drill. Carbide tipping provides long service life across the volume of hinge holes required in production cabinet manufacturing — each door typically requires two to three cup hinge mortises. The 57mm overall length fits standard hinge boring machines with appropriate depth stop capability to produce the correct mortise depth for the specific hinge brand being installed.
