ABSTRACT ANNULAR HOLE CUTTER A tipped annular hole cutter is made by brazing all the cutting tips (30) simultaneously to the cylindrical wall (12) of the cutter body. The tips (30) have outer and inner lands (32, 34) which locate against the outer and inner surfaces (52, 54) of the cylindrical wall (12). This accurately locates the tips radially during.brazing. The radially inner face (46) of the tip (30) is inclined so as to define an inner clearance face which has the necessary circumferential and radial clearances without there being any need to grind the inner face (46) after brazing. The tips (30) are received in skewed slots (18) whose angle of skew (alpha) is less than the angle of spiral (beta) of the flutes (70). The front rake face (43) is ground to provide an optimum cutting action whereas the flutes are designed independently to achieve optimum chip removal.
