EAGLE TOOL US
Frequently asked questions
Common questions about EAGLE TOOL US from 3G Electric.
What is the Switch Bit system on Eagle Tool US cable drill bits?
The Switch Bit system is an interchangeable head and shank design. The shank remains in the drill chuck while the cutting head can be removed and replaced with a different size or material type. This allows one shank to serve multiple drilling tasks, reducing the need to swap entire bits. Eagle Tool US offers shanks in 3/16 in and 1/4 in hex diameters, and heads in carbon steel or carbide-tipped configurations. The system is used in electrical and low-voltage cabling work where holes of varying diameters are required in wood, metal studs, drywall, or masonry.
What shank diameters are available for Eagle Tool US cable drill bits?
Eagle Tool US cable drill bits are available with 3/16 in and 1/4 in hex shanks. The 3/16 in shank is used for smaller-diameter holes and fits standard drill chucks. The 1/4 in shank provides a larger interface for heavier drilling. Both shank sizes are part of the interchangeable head and shank system, so the same shank can accept different heads. When selecting, match the shank diameter to the drill chuck and the expected load. Overall lengths range from 5 in to 69 in, depending on the model.
What materials can Eagle Tool US cable drill bits drill through?
Eagle Tool US cable drill bits are designed for wood, metal studs, drywall, and masonry. Carbon steel heads are typically used for wood and drywall. Carbide-tipped heads, such as the ETM500 model, are intended for masonry and other abrasive materials. The specific material capability depends on the head type and drill bit size. For example, the ETH375 carbon steel head is used for wood or metal studs, while the ETM500 carbide-tipped head is used for wood, drywall, and masonry. Always match the head material to the workpiece.
What is the longest Eagle Tool US cable drill bit available?
The longest Eagle Tool US cable drill bits in the catalog have an overall length of 69 in. Models include the ET18769 with a 3/16 in hex shank and the ET25069 with a 1/4 in hex shank. These extended-length bits are used when the drill cannot be positioned close to the work surface, such as drilling through top plates or in confined ceiling spaces. They are part of the interchangeable head and shank system, so the head can be changed without removing the shank from the drill.
Are replacement heads available for Eagle Tool US cable drill bits?
Yes. The interchangeable head and shank design allows replacement heads to be purchased separately from shanks. This is useful for maintenance and procurement because only the worn head needs to be replaced, not the entire bit. Eagle Tool US lists head models such as ETH375, ETH500, and ETM500, which correspond to different drill bit sizes and materials. When ordering, specify the head model and the shank diameter to ensure compatibility. 3G Electric lists manufacturer part numbers for each SKU to simplify reordering.
What drill bit sizes are available in the Eagle Tool US cable drill bit line?
Eagle Tool US cable drill bits are available in drill bit sizes including 3/8 in and 1/2 in. The ETH375 model is a 3/8 in carbon steel head, while the ETH500 and ETM500 models are 1/2 in heads in carbon steel and carbide-tipped respectively. Additional sizes may be available across the full catalog of over 110 SKUs. The drill bit size determines the hole diameter for cable routing. Select the size based on the cable bundle or conduit outside diameter and the clearance required for installation.
