Key Features

  • Short length offers the greatest rigidity of the various drill bit lengths
  • High-speed steel (HSS) containing cobalt is a good combination of toughness and hardness, for use on drilling into hard materials
  • Titanium carbon nitride (TiCN) coating lubricates drill bits for high-temperature stability and offers better abrasion resistance than TiN coating
  • 135-degree split-point angles for centering and to reduce pressure on cutting edges
  • Round shanks, for use on a variety of tool-holding systems

Product Description

The Cleveland 2133 short length high-speed steel (HSS) containing cobalt drill bit has a 30-degree helix angle, with a 135-degree split-point drill point and titanium carbon nitride (TiCN) surface treatment, which helps optimize performance in general-purpose drilling applications. The shank diameter is the same as the drill size.

While the 2133 series can be used on most materials, it is most suitable for drilling into stainless steel, tool steel, carbon steel, and cast iron. TiCN coating lubricates the drill bit for high-temperature stability, and offers increased hardness and greater abrasion resistance than uncoated or TiN-coated tools. Spiral flutes act as a passageway for chip extraction from the hole and for coolant to enter the hole. The twist of the flutes brings chips up and away from the cutting edge. 135-degree split-point reduces walking when starting a hole and penetrates more easily than a convention point. Round shanks allow use with a wide variety of tool holding systems.

The 2133 series is most suitable for drilling into stainless steel, various steels, and cast iron. TiCN is harder than TiN and has lower friction. It combines toughness with good wear resistance. Spiral flutes act as a passageway for chip removal and for coolant to enter the hole. The right-hand twist brings chips up and away from the cutting edge. Round shanks allow use with a wide variety of tool holding systems. 135-degree split-point reduces walking when starting a hole and penetrates more easily than a convention point.

HSS containing cobalt which can be run at faster speeds and stays sharp longer than HSS tools, while offering resistance to heat and abrasion. It provides heat and wear resistance to help extend tool life and it adheres to Deutsches Institut für Normung (DIN) 1897 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” through 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. Short length drill bits (also called stub or screw-machine length) are the shortest and stiffest twist bits, helping to reduce the chance of deflection or breakage when drilling.

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.
