Key Features

  • Coolant channels to drill point to help reduce friction and temperatures, and for longer drill life, less downtime, fewer regrinds, and less cost per hole
  • Black oxide finish, for improving lubricity, resisting corrosion, and resistances to chipping or flaking
  • High-speed steel (HSS), for use on a wide variety of materials
  • 118-degree conventional point angles, for general drilling applications
  • Round shanks, for use on a variety of tool-holding systems

Product Description

The Cleveland 2580 coolant feed, regular length, low helix (15-degree), high-speed steel (HSS) drill bit has a 118-degree geometry and black oxide surface treatment, which is designed for high-performance drilling applications. Best usage in numerical control (NC) or computer numerical control (CNC) applications where high productivity and accurate holes is needed. Speeds can be increased by 10% and feeds can be increased 25%. The shank diameter is the same as the drill size.

With a through-coolant system, there are different ways to get coolant through the drill bit. As the coolant flows through the coolant holes, it flushes chips and debris away from the cutting zone and moves them along the drill flutes until they exit the hole. The key factors are coolant volume and pressure. The benefits of providing coolant internally directly to the cutting edge include higher cutting speeds, higher feed rates, longer tool life, less frequent sharpening, and a superior finish. The coolant assists in clearing the chips from the cutting edge and its pressure forces the chips along the lines of the flutes, which allow for drilling greater depths without repeated withdrawal of the drill to clear chips. Higher than normal speeds and feeds are needed to help ensure chips to curl and break, instead of producing long strings. The low, also called slower helix are stronger but have less chip lifting power than higher helix but are good for harder materials with high feed rates. Good for horizontal drilling applications such as drilling on a lathe.

The 2580 series performs best when drilling into various steels, cast iron, titanium alloys, and stainless steel. Black 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 extraction from the hole and for coolant to enter the hole. Right-hand twist brings chips up and away from the cutting edge. Round shanks allow use with a wide variety of tool holding systems.

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. 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.
