Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang CMT dari 3G Electric.
What shank sizes are available for CMT router bits stocked by 3G Electric?
CMT router bits in the 3G Electric catalog are available with shank diameters of 1/4 in., 1/2 in., and 8 mm, depending on the specific bit model. For example, the flush-trim bit SKU 22ED17 has a 1/4 in. shank, while the round-groove bit SKU 45DK88 uses a 1/2 in. shank. Always verify the shank size against your router collet before ordering.
Are CMT router bits suitable for CNC routers?
Yes, CMT router bits are compatible with CNC routers as long as the shank diameter matches the collet size of the machine. The bits are precision-ground to maintain concentricity, which is critical for CNC operations. For CNC use, select bits with a 1/2 in. shank for better rigidity, though 1/4 in. shank bits can be used with appropriate collet adapters.
What materials can CMT carbide-tipped router bits cut?
CMT carbide-tipped router bits are designed for cutting hardwoods, softwoods, plywood, MDF, particleboard, laminates, and some non-ferrous metals like aluminum. The micro-grain carbide tips maintain sharpness longer than high-speed steel bits when cutting abrasive materials such as MDF or plywood. Avoid using these bits on ferrous metals or materials with high silica content.
How do I select the correct CMT flush-trim bit for template work?
For template work, choose a flush-trim bit with a bearing that matches the template thickness. The bearing diameter should equal the cutter diameter so the bit follows the template edge without offset. CMT flush-trim bits like SKU 806.629.11 (1/2 in. cutter diameter, 2 flutes) are suitable for pattern routing. Ensure the length of cut exceeds the workpiece thickness for a clean pass.
What is the difference between single-flute and two-flute CMT router bits?
Single-flute CMT bits, such as SKU 816.064.11, remove material faster per revolution and are ideal for softwoods or roughing passes. Two-flute bits, like SKU 806.690.11, provide a smoother finish and are better for hardwoods and final passes. Two-flute bits also reduce vibration at higher feed rates, but require more power from the router.
