CLEVELAND

Cleveland is a long-established brand in the metal-cutting tool industry, with a product history that traces back to the early 20th century. The line is known for taps, end mills, drill bits, countersinks, and related holemaking and threading tools used in general machining, maintenance, and assembly operations. 3G Electric supplies the Cleveland range as part of its industrial-equipment catalog, with current stock including NAS-spec cobalt aircraft-extension drill bits, general-purpose carbide square end mills, and fast-cutting single-flute countersinks in high-speed steel and carbide. The product families cover several core categories: holemaking tools such as aircraft-extension drills and countersinks; threading tools including taps; and milling tools such as square end mills. These are used across metalworking, aerospace component fabrication, automotive repair, and general plant maintenance where accurate hole size, thread form, and surface finish matter. Technical buyers will find specifications that support repeatable performance: aircraft-extension drills in NAS 907 Type J geometry with 135° split points and straw/bronze cobalt finish for heat resistance; carbide end mills with AlTiN coating for wear resistance in higher-temperature cutting; and countersinks in 60°, 82°, and 120° included angles with single-flute designs for chatter reduction. Sizes range from small-diameter tooling, such as a 2 mm mill diameter or 1/8 in countersink body, up to larger body diameters like 1-1/2 in. Shank sizes and overall lengths are specified per tool to match machine and application requirements. Materials include high-speed steel with black oxide finish for general use and cobalt or carbide for more demanding conditions. 3G Electric supports the Cleveland line by stocking a broad SKU count, providing spec-level product data, and sourcing items for global delivery. The catalog includes both inch and metric dimensions, reflecting the mixed requirements of international maintenance and production environments. For procurement and plant engineering teams, the emphasis is on matching the tool geometry, material, and coating to the workpiece and machine setup. Cleveland tooling is commonly specified where standard holemaking and threading operations need consistent dimensions and predictable tool life. 3G Electric’s role is to make that specification process straightforward: identify the required angle, diameter, flute count, and material, then confirm availability from the Cleveland range. The brand’s product data is presented with manufacturer part numbers and key dimensions so buyers can cross-reference against existing tool lists or machine requirements. This approach suits maintenance departments, job shops, and OEM production lines that need to replace or standardize cutting tools without extended downtime. The Cleveland portfolio is not limited to the sample items above; it spans a wider set of taps, drills, end mills, and countersinks. 3G Electric continues to add SKUs and can quote against specific part numbers or dimensional requirements. For technical selection, the relevant variables are workpiece material, hole depth, required tolerance, machine spindle type, and whether a through-hole or blind-hole operation is involved. Cleveland tools are manufactured to published dimensional standards, and the NAS-spec aircraft-extension drills follow a recognized aerospace geometry. The countersinks are available in the common included angles used for flat-head screw seating, and the end mills cover square-profile milling in general-purpose carbide grades. This makes the line suitable for both one-off maintenance jobs and repeat production where tool-to-tool consistency is expected.

Frequently asked questions

Common questions about CLEVELAND from 3G Electric.

What is the Cleveland NAS 907 Type J aircraft-extension drill bit used for?

The Cleveland NAS 907 Type J aircraft-extension drill bit is designed for drilling in confined spaces where a standard jobber-length drill cannot reach. It has an extended overall length, such as 6 inches on the #25 size, with a 135° split point for reduced thrust and improved centering. The straw/bronze cobalt construction provides heat resistance for drilling harder materials. Typical uses include aircraft assembly, airframe maintenance, and any application requiring a long-reach drill with NAS-spec geometry. The bit is available in specific diameters, including 0.1495 inch for the #25 size, and is identified by manufacturer part numbers such as C08146.

What angles are available in Cleveland single-flute countersinks?

Cleveland single-flute countersinks are available in 60°, 82°, and 120° included angles. The 82° angle is commonly used for flat-head screws in inch-based fastening, while 60° and 120° cover other standard countersink requirements. Body diameters range from 1/8 inch up to 1-1/2 inches in the current 3G Electric catalog. Materials include black oxide high-speed steel for general use and carbide for higher-speed cutting. The single-flute design is intended for fast, chatter-free cutting and produces conical recesses for flat-head screws or deburring. Manufacturer part numbers include C46113, C46114, C46129, C46131, C46141, and C46328.

What coating is used on Cleveland general-purpose carbide square end mills?

Cleveland general-purpose carbide square end mills in the 3G Electric catalog use an AlTiN coating. AlTiN is an aluminum titanium nitride coating that provides heat and wear resistance, making it suitable for milling a range of materials including steels and stainless steels. The end mills have a square profile, 4 flutes, and are available in metric sizes such as 2 mm mill diameter with 5.18 mm length of cut and 40 mm overall length. The 4-flute geometry is generally used for finishing and general milling where chip evacuation and surface finish are priorities. Manufacturer part numbers include C98242.

What materials are Cleveland cutting tools made from?

Cleveland cutting tools are made from several materials depending on the tool type and application. High-speed steel with a black oxide finish is used for many countersinks and general-purpose drills, providing wear resistance and reduced friction. Cobalt steel is used in aircraft-extension drills, such as the NAS 907 Type J, for heat resistance in demanding drilling. Carbide is used in end mills and some countersinks for higher cutting speeds and extended tool life. The specific material is listed per SKU, and selection depends on workpiece material, machine speed, and required tool life. 3G Electric lists the material and coating for each Cleveland item in the catalog.

How do I select the right Cleveland countersink for flat-head screws?

To select a Cleveland countersink for flat-head screws, match the included angle to the screw head angle. Common inch flat-head screws use an 82° angle, while metric flat-head screws often use a 90° angle; Cleveland offers 82° and other angles such as 60° and 120° for different standards. Choose a body diameter that produces the required countersink diameter without exceeding the screw head size. Single-flute countersinks are intended for fast, chatter-free cutting and are available in high-speed steel and carbide. Shank diameter must match the machine or hand tool. For specific part numbers, refer to the Cleveland catalog data or contact 3G Electric with the screw size and material.

Does 3G Electric supply Cleveland taps and other threading tools?

Yes, 3G Electric supplies Cleveland taps and other threading tools as part of its Cleveland cutting tool range. The catalog includes taps in various styles and sizes, along with the drills, end mills, and countersinks shown in the current sample. Threading tools are used for creating internal threads in holes, and selection depends on thread standard, material, and whether the hole is through or blind. 3G Electric provides manufacturer part numbers and dimensional data to help match existing specifications. For specific tap sizes or thread forms not listed, 3G Electric can source against part numbers or dimensional requirements. Availability is confirmed at the time of quote.
