Abstract

The drill 1 for producing holes in composite materials such as carbon fibre reinforced plastics includes an elongate drill body 2 having a shank portion 3 at one end and a tip portion 4 at another end. The tip portion has a maximum outside diameter D. End cutting edges (306, 307, 317, 318, Figure 3) each extend between a main central axis of the drill body and a circumferential periphery of the body. Circumferential cutting edges 11, 12 each extend along a length of the drill. Each end cutting edge forms a continuous cutting edge with a corresponding respective circumferential cutting edge. Each end cutting edge has a minimum radius of curvature R wherein R=D/12 to R=D/2. R may be in the range of 9 to 46 percent of D or 0.75mm to 3.2 mm. The tip may be of solid diamond or have a coating of polycrystalline diamond. The drill also includes flutes 5, 6 and end facets (300 to 304, 310, 311, Figure 3).
