CMT Flush Trim Bit - 3/8 in. Dia. x 1/2 in. H. 1/4 Shk

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

Built for precision, durability, and smooth cutting performance, the CMT Flush Trim Bit is an essential router bit for woodworkers, cabinetmakers, and professionals who need clean, accurate trimming results. Featuring a 3/8 in. diameter and 1/4 in. shank, this carbide-tipped bit is well suited for laminate trimming, template routing, pattern work, and a variety of general woodworking applications.

The flush trim design allows the bit to follow an existing edge or template while removing excess material for a consistent, flush finish. Its carbide cutting edge provides dependable performance and long service life, making it a versatile addition to any router bit collection.

Versatile Flush Trimming Performance

CMT Flush Trim Bits are designed to handle a wide range of precision trimming tasks. Use them to trim laminate flush with a substrate, follow templates for repeatable shapes, or clean up edges after rough cutting. The guided cutting action helps produce consistent results while reducing the need for extensive hand finishing.

Shop Tips

CMT Flush Trim Bits can also be useful when creating through mortises. Begin by using a straight bit to cut the groove for the mortise. Drill a hole through the workpiece at one end of the groove, then turn the workpiece over and continue the cut from the opposite side.

For best results, select a flush trim bit with a cutting length slightly longer than the fillet. Follow the groove created on the opposite side of the workpiece while allowing the ball-bearing guide to maintain a consistent cutting path. This technique can help produce clean, accurately aligned mortises.

Safety Precautions

Always inspect the router bit before use and never operate a damaged, cracked, or excessively worn bit. Secure the workpiece properly and operate the router at the manufacturer's recommended speed and feed rate. Avoid forcing the bit through the material, particularly when working with small-diameter cutters.

When removing a significant amount of material, use multiple passes rather than attempting to make one deep cut. Multiple passes can improve router control, reduce stress on the cutting edges, and help produce a cleaner finished surface.

How CMT Produces High-Quality Router Bits

• Precision Turning, Milling, and Cutting
  CMT invests in advanced manufacturing technology to produce accurately machined router bit bodies and shanks. Fully automated CNC machinery operated by trained technicians helps ensure precise dimensions, proper balance, and consistent performance.
• Heat-Forged Steel Bodies for Large-Diameter Bits
  Large-diameter router bits can require additional manufacturing processes. CMT heat-forges the steel before precision machining when appropriate, creating a radial grain structure designed to improve strength, durability, and resistance to demanding cutting conditions.
• Advanced Brazing Technology
  Computerized brazing equipment creates a consistent bond between the steel body and carbide cutting tips. CMT's silver-copper-silver brazing process provides a strong connection while helping absorb shock and protect carbide edges during demanding applications.
• Specially Formulated Carbide
  DiFaceframeerent woodworking materials and cutting applications require diFaceframeerent carbide characteristics. CMT uses carbide grades formulated for specific applications, providing an appropriate balance of hardness, edge retention, and impact resistance.
• Precision Grinding and Sharpening
  Each cutting edge undergoes precision grinding and sharpening to meet CMT's standards for sharpness and accuracy. Properly finished cutting edges help deliver clean cuts, smooth operation, and dependable performance throughout the useful life of the bit.
