These conical cutters offer a significant advantage over traditional drills by providing a positive stop at a specific hole size, allowing you to cut perfectly round holes in various materials such as sheet metal, steel, copper, aluminum, and plastic without the need for multiple drill bit changes. The self-starting, non-working design eliminates the need for a pilot drill. Manufactured from HSS for maximum strength and durability, the drills feature 12mm flat shanks compatible with most drilling machines (electric, battery, or air-powered). Double flutes ensure a perfectly round hole and automatically deburr as you drill. For optimal performance, especially when drilling aluminum, ensure the drills are well-lubricated. These drills have an HRC 62 rating. The set includes five drills with the following step sizes: Drill 1: 3/16”, 1/4", 5/16”, 3/8”, 7/16” and 1/2"; Drill 2: 1/8”, 5/32”, 3/16”, 7/32”, 1/4", 9/32”, 5/16”, 11/32”, 3/8”, 13/32”, 7/16”, 15/32” and 1/2"; Drill 3: 1/4", 5/16”, 3/8”, 7/16”, 1/2", 9/16”, 5/8”, 11/16” and 3/4"; Drill 4: 1/4”, 3/8”, 1/2", 5/8”, 3/4", 7/8”, 1”, 1-1/8”, 1-1/4” and 1-3/8”; Drill 5: 1/4", 5/16”, 3/8”, 7/16”, 1/2", 9/16”, 5/8”, 11/16”, 3/4", 13/16” and 7/8”.
