CMT 3-Flute Slot Cutter Without Arbor and Bearing - 1/8 in. Slot

CMT 3-Flute Slot Cutter without Arbor and Bearing – 1-7/8 in. Dia. – 1/8 in. Slot

The CMT 3-Flute Slot Cutter is designed to produce clean, accurate slots for woodworking applications. This cutter is supplied without an arbor or bearing, allowing you to select the appropriate CMT arbor and bearing configuration for your specific routing setup.

A high-quality, perfectly concentric arbor is essential for achieving smooth and precise routing results. CMT arbors are carefully machined from special high-strength steel and precision ground in all critical areas for dependable performance and accurate cutter rotation.

Product Features

• 3-wing carbide-tipped design provides efficient cutting and smooth slotting performance.
• 1-7/8 in. cutter diameter is suitable for creating consistent slots in a variety of woodworking applications.
• 1/8 in. slot width is ideal for applications requiring a narrow, accurately sized slot.
• 8mm bore fits CMT 1/4 in. and 1/2 in. arbors.
• Anti-kickback design helps provide controlled and safer cutting performance.
• Carbide-tipped construction provides a durable cutting edge and extended service life.
• Orange P.T.F.E. industrial coating helps reduce friction and resin buildup while allowing the cutter to move smoothly through the material.
• Arbor and bearing sold separately, giving you flexibility when configuring your routing setup.

Precision CMT Construction

CMT router bits are manufactured using carefully controlled production processes designed to deliver accuracy, balance, durability, and dependable cutting performance. Automated CNC machinery operated by specially trained technicians helps ensure that router bit shanks and bodies are manufactured to precise specifications.

Heat-Forged Steel Bodies

Large-diameter router bits require additional strength and durability. CMT heat-forges the steel used for certain larger cutter bodies before precision machining. This process creates a radial grain orientation that helps provide increased strength and durability where it is needed most.

Precision Carbide Brazing

CMT uses specialized computerized brazing equipment to provide consistent bonds between the carbide and steel body. A silver-copper-silver brazing process creates a strong connection while helping absorb shock during cutting, protecting the carbide tips when working with demanding materials and harder woods.

Application-Specific Carbide

Different woodworking materials place different demands on a cutting tool. CMT formulates carbide grades for specific applications, balancing hardness and impact resistance according to the intended use. This helps provide the appropriate combination of edge durability, cutting performance, and resistance to impact.

Precision Grinding and Sharpening

The final grinding and sharpening process is performed with multi-axis CNC machinery for exceptional precision. Cutting angles and bevels are carefully ground to produce sharp, consistent cutting edges that help deliver clean and accurate results.

Safety Tips

• Always wear appropriate eye protection when operating a router.
• Wear a suitable dust mask or respirator when routing wood or other materials that generate airborne dust.
• Never use a router cutter that is damaged, cracked, excessively worn, or otherwise compromised.
• Always operate the router at the manufacturer's recommended speed and use the proper feed rate.
• Do not force the cutter through the workpiece. Allow the cutting edges to remove material at a controlled rate.
• When making an initial cut, pay particular attention to maintaining control of the router and workpiece.
• For applications requiring deeper cuts, consider making multiple passes rather than removing excessive material in a single pass.

Recommended Use

The CMT 3-Flute Slot Cutter is a practical choice for woodworkers who need to create clean, consistent 1/8 in. slots. Its carbide-tipped, anti-kickback design and durable industrial coating make it well suited for professional woodworking shops, cabinetmaking, furniture construction, and general routing applications where precise slotting is required.
