Abstract: A drill for thick plate material of over 10 mm depth. Drills for cutting thin plate material by way of hand held electric drills are known, but for drilling thick plate material, there has hitherto been used hollow drills that necessitate the use of central ejectors to remove a slug of metal cut from a plate, with added costs and complexity. This is avoided by providing a construction which includes a solid body formed with a central cutting tip at one end, behind which and extending towards the rear end of the drill is a first land of a required diameter and of a length of at least 11 mm, followed by at least one other land of required greater diameter and of a length of at least 11 mm, with a cutting shoulder connecting one land and a succeeding land, the body at the opposite end to the cutting tip, being provided with a connector whereby the drill can be secured to the chuck of a bench mounted drill or a portable drilling machine.
