Cleveland 2001G Style High Speed Steel Jobbers' Drill Bit, Black Oxide, Round Shank, 118 Degree Point, 37/64" Size (Pack of 1)

The Cleveland 2001G, also called CLE-MAX 2001G, is a jobber length, vanadium steel drill bit has a 38-degree helix angle, with a 118-degree conventional point and black oxide surface treatment, is suitable for general-purpose drilling applications. Jobber length provides a longer reach and more rigidity than shorter lengths. The shank diameter is the same as the drill size. While the 2001G series of drill bits can be used for drilling into most material, it is most suitable for drilling into low carbon steel, cast iron, aluminum, and copper alloys. Black oxide, also called steam oxide improves lubricity, resists corrosion, and resists flaking. It also helps prevent buildup and welding of material on the tool’s cutting edge when machining iron and steel. Spiral flutes act as a passageway for chip removal and for coolant to enter the hole. The twist of the flutes brings chips up and away from the cutting edge. The 118-degree drill point is the most common angle for general purpose drilling across a wide range of materials. The faster helix angle provides greater lifting power for chip removal than a lesser helix angle. Round shanks allow use with a variety of tool holders.Vanadium steel is high-speed steel (HSS) with a high percentage of vanadium, for greater heat resistance and an increased ability to hold an edge over high-speed steel (HSS).They adhere to Deutsches Institut für Normung (DIN) 338 standards.The tolerances for various aspects of the Cleveland drill bits are: drill diameter range through 1/8” +0.0000”/-0.0005”, over 1/8” to 1/4” +0.0000”/-0.0007”, over 1/4” to 1/2” +0.0000”/-0.0010”, over 1/2” to 1” +0.0000”/-0.0012”, over 1” to 2” +0.0000”/-0.0015”, over 2” to 3-1/2” +0.0000”/-0.0020”; drill overall length and flute length #80 through 1/8” +0.1250”/-0.0626”, over 1/8” to 1/2” +0.1250”/-0.1250”, over 1/2” to 1” +0.2500”/-0.1250”, over 1” to 2” +0.2500”/-0.2500”, over 2” to 3-1/2” +0.3750”/-0.3750”; drill point angle diameter range 1/16” to 1/2” included angle 118 or 135 degrees +/-5 degrees, over 1/2” to 1 1/2” included angle 118 degrees +/-3 degrees, over 1-1/2” to 3-1/2” includes angle 118 degrees +/- 2 degrees; drill lip height diameter range 1/16” to 1/8” total indicator variation 0.0020”, over 1/8” to 1/4” total indicator variation 0.0030”, over 1/4” to 1/2” total indicator variation 0.0040”, over 1/2” to 1” total indicator variation 0.0050”, over 1” to 3 1/2” total indicator variation 0.0060”.Drill bits are cutting tools used to make holes in a range of materials. They are used in machines such as handheld portable drills, drill presses, machining centers, and lathes. Drill bits come in a variety of types and lengths. Twist drill bits are the most common type of drill bit. They are a round, twisted shaft, end-cutting tool with two or more cutting edges and two or more flutes. Jobber drill bits are the most common length of twist bit. They offer a good comprise of length and reach to work with the widest range of materials and applications.Greenfield Industries manufactures tools under the brand names Cleveland, Chicago-Latrobe, Cle-Line, Vermont Tap & Die, Bassett, Putnam Tools, Geometric, Vers-O-Tool, H & G, and Acme-Fette. The company, owned by Top-Eastern Group and headquartered in Seneca, SC, makes tools that meet American National Standards Institute (ANSI), National Aerospace Standard (NAS), and Deutsches Institut für Normung (DIN) standards.
