CMT Flush Trim Bit - 3/8 in. Dia. x 1 in. H. 1/4 Shk

CMT Flush Trim Bit – 3/8 in. Dia. – 1/4 in. Shank

Fast-cutting, durable, and versatile, CMT Flush Trim Bits are designed for a wide range of trimming applications. Available in multiple sizes to meet your woodworking needs, these carbide-tipped bits deliver precise results on laminates, veneers, and template routing projects with an exceptionally smooth finish.

CMT Flush Trim Bits are essential tools for both professional woodworkers and hobbyists. Their precision-ground carbide cutting edges provide clean, accurate cuts for pattern work, laminate trimming, and other detailed routing tasks.

Safety Tips: Dust and chips from laminate materials can be hazardous to your health. Always wear a dust mask and proper eye protection when routing.

Shop Tips: These bits are excellent for creating through mortises. Start by using a straight bit to cut the mortise groove. Drill a hole through the workpiece at one end of the groove, then turn the workpiece over to complete the mortise. Select a flush trim bit with a cutting length slightly longer than the material thickness and use the ball-bearing guide to follow the groove created on the opposite side.

Safety Precautions: Never use damaged or worn router bits. Always maintain the recommended feed rate and avoid forcing the bit through the material. Take extra care when making initial cuts with small-diameter bits. For the best results, make multiple passes when working with smaller bits.

How CMT Produces High-Quality Router Bits

• Turning, Milling, and Cutting: CMT continues to invest in advanced manufacturing technology. Automated CNC machinery, operated by specially trained technicians, ensures that every router bit shank and body is manufactured with exceptional accuracy and balance.
• Heat-Forged Steel Bodies for Large-Diameter Bits: Some router bits require additional manufacturing steps to achieve maximum strength. Larger-diameter bits are heat forged before precision machining, creating a radial grain structure that improves durability and resistance to stress.
• Advanced Brazing Technology: CMT has pioneered precision brazing techniques to create a strong, consistent bond between the steel body and carbide tips. The custom silver-copper-silver brazing process provides a shock-absorbing layer that helps protect carbide edges during demanding cuts.
• Specially Formulated Carbide for Specific Applications: Different woodworking materials require different cutting characteristics. CMT engineers carbide compositions for specific applications, ranging from ultra-hard formulations for demanding laminate cutting to tougher, impact-resistant grades for large-profile bits.
• Grinding and Sharpening: The final production stage uses precision grinding and sharpening processes to create sharp, consistent cutting edges. This attention to detail ensures smooth performance, accurate results, and long tool life.
