CLEVELAND

CLEVELAND is a brand of cutting tools, primarily known for its extensive line of drills, reamers, counterbores, and countersinks. The brand's product focus is on precision tooling for metalworking, with a strong emphasis on aerospace-grade tooling such as NAS-spec aircraft extension drills. These tools are manufactured to meet specific standards like NAS 907 Type B and Type J, indicating compliance with National Aerospace Standards. The product range includes high-speed steel (HSS) and cobalt variants, with finishes such as black oxide and straw/bronze, which enhance wear resistance and reduce friction. CLEVELAND tools are designed for industrial applications requiring tight tolerances, such as drilling, reaming, and countersinking in materials like aluminum, steel, and alloys. Key specifications include diameters from 0.0700 inches to 3/4 inch, overall lengths up to 12 inches, and shank types like Morse Taper (MT3) for bridge reamers. The brand also offers interchangeable-pilot counterbores and multi-flute countersinks with angles like 82°, available in carbide or HSS. 3G Electric supplies a broad inventory of CLEVELAND cutting tools, including over 5,000 SKUs, covering taps, end mills, drill bits, and reamers. The catalog includes both standard and specialty items, such as aircraft extension drills with 135° split points for reduced thrust and improved chip evacuation. For procurement specialists and plant engineers, CLEVELAND tools provide reliable performance in production environments, with options for impact-rated or non-impact-rated tools depending on the application. 3G Electric supports the line by offering detailed specifications, including diameter, length, shank type, and material, enabling buyers to select the correct tool for their machining operations. The brand's history is rooted in industrial tool manufacturing, with a focus on durability and precision, though specific founding details are not widely publicized. CLEVELAND tools are commonly used in aerospace, automotive, and general manufacturing sectors where consistent quality and adherence to standards are critical. 3G Electric's global distribution ensures availability of these tools for maintenance, repair, and production needs, with no geographic restrictions on supply.

Frequently asked questions

Common questions about CLEVELAND from 3G Electric.

What types of materials are CLEVELAND aircraft extension drills made from?

CLEVELAND aircraft extension drills are available in high-speed steel (HSS) and cobalt steel. HSS variants, such as those meeting NAS 907 Type B, offer good wear resistance for general-purpose drilling in materials like aluminum and mild steel. Cobalt variants, like those with straw/bronze finish, provide higher heat resistance and hardness, making them suitable for tougher alloys and stainless steel. The choice depends on the material being drilled and the required tool life.

What is the significance of the NAS 907 specification in CLEVELAND drills?

The NAS 907 specification is a National Aerospace Standard that defines dimensional and performance requirements for aircraft extension drills. CLEVELAND drills meeting NAS 907 Type B or Type J are designed for precision drilling in aerospace applications, ensuring consistent shank diameter, flute geometry, and point angle (typically 135° split point). This standard ensures interchangeability and reliability in critical assemblies, such as airframe components.

Are CLEVELAND bridge reamers impact rated?

CLEVELAND bridge reamers, such as the model with a 3/4 inch size and MT3 shank, are typically not impact rated. These reamers are designed for manual or machine use in reaming operations to enlarge or finish holes to precise diameters. They are made from black oxide high-speed steel for durability but should not be used with impact drivers, as the shank and cutting edges may fracture under sudden torque loads.

What is the difference between CLEVELAND single-flute and six-flute countersinks?

CLEVELAND single-flute countersinks, like the 82° 1-flute model in black oxide HSS, are designed for fast cutting and chip clearance, making them suitable for softer materials or quick deburring. Six-flute countersinks, such as the 82° carbide variant, provide a smoother finish and reduced chatter, ideal for harder materials or applications requiring a polished surface. The choice depends on the desired surface finish and material hardness.

Can CLEVELAND interchangeable-pilot counterbores be used with different pilot diameters?

Yes, CLEVELAND interchangeable-pilot counterbores, such as the model with a 9/16 inch bore diameter, are designed to work with pilot diameters ranging from 1/4 inch to 1/2 inch. The interchangeable pilot system allows the same counterbore body to be used with various pilot sizes, enabling flexibility in counterboring operations for different screw head sizes. Pilots are typically sold separately.
