The Cleveland 2565 parabolic flute design, long-length high-... See more product details
The Cleveland 2565 parabolic flute design, long-length high-speed steel (HSS) drill bit has a 38-degree helix angle, with a 118-degree notched-point drill point and uncoated (bright) surface treatment, which is designed for high-performance drilling applications. It can drill up to 14 times the diameter of the drill deep. The round shank diameter is the same as the drill size with a tang, provides a means to securely hold the drill bit in the tool holder.
The 2565 series performs best when drilling into low-carbon steel, soft alloy steel, non-ferrous materials, aluminum, copper alloys, and free-machining stainless steel. The uncoated finish helps increase chip flow in soft materials. 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. The parabolic design combined with the 38-degree helix angle increases the chip removal capacity over a non-parabolic design. The 118-degree notched-point drill point works well for hard and tough materials. The notched point can withstand higher thrust loads and has same benefits as a split-point design. Round shanks allow use with a wide variety of tool holding systems. The long, also known as taper length has more reach than Jobber-length bits and allows for deeper holes. Made of HSS which is a common, general-purpose steel for cutting tools, offers toughness and shock resistance, and is compatible with a variety of materials.
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. Long length bits (also called taper length) are twist bits that are a little longer than jobber length, allowing for deeper holes and longer reach.
