HOLESAWS - BI METAL COBALT
Bi-Metal Cobalt Holesaws for Professional Cutting
Shop bi-metal cobalt holesaws at Order Electrical, with professional cutting accessories for electricians, installers, engineers and other tradespeople requiring accurate circular holes in a variety of materials.
Bi-metal holesaws combine a tough, flexible body with a hard cutting edge containing cobalt alloy, providing durability and cutting performance across demanding installation applications.
For electricians, these holesaws are particularly useful for producing openings for cable entries, conduit, glands, trunking and electrical accessories, as well as drilling through suitable metal, timber and other construction materials.
Our range can include bi-metal cobalt holesaws in a selection of diameters, allowing installers to choose the appropriate size for the required opening. Compatible arbors, mandrels and pilot drills may be required depending on the holesaw system being used.
Bi-metal cobalt holesaws are commonly used for cutting steel, non-ferrous metals, wood and plastics, subject to the manufacturer's specification. Suitability for stainless steel and other demanding materials should be checked for the individual holesaw.
Choosing the Right Bi-Metal Cobalt Holesaw
Start by selecting the correct holesaw diameter for the required opening. For electrical installation work, consider the finished size needed for the gland, conduit, fitting or accessory rather than relying solely on its nominal size.
Check the material and thickness being cut, together with the holesaw's stated cutting depth. Different materials require different cutting speeds, and using the correct speed can significantly affect cutting performance and holesaw life.
Also check arbor and pilot drill compatibility. Some holesaw systems use different arbors for smaller and larger diameters, so the holesaw and arbor should be confirmed as compatible before use.
When cutting metal, an appropriate cutting lubricant and controlled drilling speed can help manage heat and extend cutting life where recommended by the manufacturer.
