CLE-LINE
Frequently asked questions
Common questions about CLE-LINE from 3G Electric.
What is the difference between CLE-LINE Black & Gold HSS and straw/bronze cobalt drill bits?
CLE-LINE Black & Gold HSS drill bits are made from high-speed steel with a surface treatment that provides wear resistance and lubricity. They are suitable for general-purpose drilling in materials such as steel, aluminum, and plastics. Straw/bronze cobalt drill bits, such as the CLE-LINE C23323, are made from cobalt high-speed steel, which offers higher heat resistance and wear resistance than standard HSS. The straw/bronze finish is a result of the heat treatment process and is not a coating. Cobalt bits are typically used for drilling harder materials like stainless steel, titanium, and high-strength alloys. Both types may feature 135° split points and 3-flats shanks depending on the specific model. Selection depends on the workpiece material and drilling conditions.
What are CLE-LINE Silver & Deming drill bits used for?
CLE-LINE Silver & Deming drill bits, such as the 1-1/32" model C27602, are designed for drilling large-diameter holes in portable drills or drill presses with a 1/2-inch chuck. They feature a reduced shank (typically 1/2 inch) to fit standard chucks, and a 118° split point to reduce walking. The bits are made from high-speed steel with a Black & Gold finish for wear resistance. Common applications include drilling holes in structural steel, pipe, and plate for maintenance, construction, and fabrication. The 3-flats shank provides a secure grip in the chuck. These bits are often used when a hole larger than 1/2 inch is needed but a larger drill chuck is not available.
What is the maximum cutting depth of CLE-LINE cobalt annular cutters?
CLE-LINE cobalt annular cutters, such as the C34147 model, have a maximum cutting depth of 2 inches. These cutters are designed for use in portable magnetic drills and are made from high-speed steel with cobalt for drilling hard materials. They include a pilot pin to help center the cutter and eject the slug. The 1/2-inch diameter cutter is part of a range of sizes available. Annular cutters are used for drilling large holes in steel plate and structural steel, often in maintenance and fabrication applications. The cutting depth is determined by the cutter's flute length and the material being drilled. For deeper holes, multiple cutters or a different tool may be required.
Are CLE-LINE jobber-length drill bits available in metric sizes?
Yes, CLE-LINE jobber-length drill bits are available in metric sizes. For example, the CLE-LINE C74002 is a 1.5 mm drill bit, and the C74017 is a 9 mm drill bit. These bits feature a 135° split point and a Black & Gold HSS finish, with a 3-flats shank. Metric sizes are commonly used in equipment and machinery that use metric fasteners and components. 3G Electric stocks a range of CLE-LINE metric jobber drills, along with inch, letter, and number sizes. The availability of metric sizes allows users to match drill bits to metric hole requirements without conversion. Specifications such as diameter, point angle, and shank type are provided for each part number.
What is the purpose of the 3-flats shank on CLE-LINE drill bits?
The 3-flats shank on CLE-LINE drill bits, such as those in the C18092 and C74042 models, is designed to prevent the bit from slipping in a drill chuck. The three flat surfaces provide a positive engagement with the chuck jaws, reducing the risk of the bit spinning during drilling. This is particularly useful in portable drilling operations where vibration and torque can cause standard round shanks to slip. The 3-flats shank is commonly found on jobber-length and Silver & Deming drill bits. It allows for higher torque transmission without the need for a keyless chuck or specialized tooling. The shank design does not affect the cutting geometry of the bit.
How does 3G Electric support CLE-LINE product selection?
3G Electric provides access to CLE-LINE product specifications, including part numbers, dimensions, point angles, finishes, and shank types. The distributor stocks over 1,500 CLE-LINE SKUs and offers global logistics support. Technical buyers can request quotations and receive product data to aid in selection. 3G Electric does not provide application engineering or custom manufacturing for CLE-LINE products, but can assist with identifying available items from the catalog. The company serves industrial customers worldwide, with shipping from multiple locations. For specific performance or certification requirements, customers should refer to the manufacturer's documentation. 3G Electric's role is to supply CLE-LINE products as part of its broader industrial equipment offering.
