Product Description
Milwaukee 1-3/8 in. Forstner Bit
Model Number: 48-14-1374
The Milwaukee 48-14-1374 is a 1-3/8 in. Forstner Bit — the European hinge cup specification bit for drilling 35mm (1-3/8 in.) flat-bottom mortises in cabinet doors and face frames for the European cup hinge standard that is the dominant hinge type in production cabinetry and residential kitchen and bath cabinet installation. The 35mm European hinge cup dimension is the worldwide standard for cup hinges from Blum, Grass, Salice, Häfele, and all other European and domestic hinge manufacturers who use this standard — the 1-3/8 in. Forstner bit is the correct and most frequently used Forstner bit size in cabinetmaking because virtually every European cup hinge installation requires one or more 35mm mortises in the door and another in the face frame for the corresponding mounting plate. Milwaukee precision-machines this bit to the accurate 1-3/8 in. diameter needed for correct hinge cup seating — even small diameter errors in Forstner bit diameter translate to hinge depth errors that affect door overlay and reveal settings throughout the cabinet installation.
The Forstner bit's three-element cutting geometry produces the flat-bottom, cylindrical-sidewall hole that European cup hinges require for correct depth seating — a hole with a conical or pointed bottom from a twist bit leaves the hinge cup unseated at the bottom of the mortise, preventing proper depth adjustment and door positioning. The outer rim cutter scores the perimeter ahead of the flat cutting face to prevent tear-out on the visible door face where the mortise is located, and the sharp center brad point establishes the hole position precisely at the marked center without walking. Milwaukee manufactures the 1-3/8 in. Forstner bit to professional cabinetmaking quality standards for the dimensional accuracy and sustained sharpness that production cabinet manufacturing requires across thousands of mortises.
Milwaukee Forstner bits are available across the range of standard woodworking diameters — see Milwaukee's complete Forstner bit lineup for all available individual sizes and sets.
