Frequently asked questions
Common questions about CMT from 3G Electric.
What types of CMT router bits does 3G Electric supply?
3G Electric supplies CMT router bits across several profile categories, including roundover, hinge-mortise, flush-trim, beading, and Roman ogee. The catalog includes carbide-tipped bits in fractional-inch sizes, with cutter diameters ranging from 3/8 in to 2-1/2 in. Both individual bits and sets are available, such as the 3-piece flush trim set (MPN 806.001.11). These bits are intended for woodworking applications on materials like solid wood, MDF, plywood, and composites. Each product listing includes manufacturer part numbers and specifications to aid selection.
What is the difference between CMT roundover bits and hinge-mortise bits?
CMT roundover bits are designed to create rounded edges on workpieces, with cutter diameters such as 1-1/8 in (MPN 838.285.11) and 2-1/2 in (MPN 838.992.11). They are used for decorative edge profiling in cabinetmaking and furniture production. Hinge-mortise bits, such as MPN 801.317.11 with a 1-1/4 in cutter diameter, are intended for cutting precise recesses for hinge installation in doors and frames. Both types are carbide-tipped and available in fractional-inch sizes. The choice depends on whether the application requires edge treatment or joinery recessing.
Are CMT router bits suitable for CNC router use?
CMT router bits are commonly used in CNC routers, as well as portable routers and shapers, provided the tooling specifications match the machine's collet size and speed requirements. The bits feature carbide tips for wear resistance and are available with bearing guides for template work. For CNC applications, users should verify the shank diameter, cutter diameter, and recommended feed rates. 3G Electric provides part numbers and specifications for each CMT bit to assist in matching tooling to machine capabilities. It is advisable to consult the machine manufacturer's guidelines for tooling compatibility.
What materials can CMT hinge-mortise bits cut?
CMT hinge-mortise bits are designed for cutting hinge mortises in wood and wood-based materials, including solid wood, MDF, plywood, and some composites. They are not intended for metals or non-ferrous materials unless specifically rated. The carbide tips allow for clean cuts in abrasive materials, but users should adjust feed rates and speeds according to the material density. For example, MPN 801.128.11B with a 1/2 in cutter diameter is suitable for cabinet door hinge recesses. Always follow the manufacturer's recommendations for material-specific applications.
Does 3G Electric provide technical specifications for CMT router bits?
Yes, 3G Electric lists technical specifications for each CMT router bit, including manufacturer part number, cutter diameter, type (e.g., carbide-tipped), and profile. For instance, the roundover bit MPN 838.992.11 has a 2-1/2 in cutter diameter and is carbide-tipped. These details help procurement specialists and engineers verify compatibility with their existing tooling and applications. 3G Electric sources genuine CMT products and can assist with part number identification. Specifications are based on manufacturer data and are provided to support accurate selection.
