CMT Super-Duty Flush Trim Bit - 3/4" Diameter x 2" Cutting Height, 1/2" Shank, Xtreme Series is a professional-grade flush trimming router bit engineered for woodworkers and CNC operators who demand razor-clean edges and extended tool life. Designed to cut material perfectly flush with a template or adjacent surface, this two-bearing flush trim bit delivers consistent, repeatable results on solid hardwood, laminates, veneers, MDF, and more. The Xtreme Series spiral technology sets this bit apart from standard flush trim bits, producing a superior surface finish while dramatically reducing wear - making it a go-to choice for high-volume template routing, pattern copying, and edge trimming applications.

Key Features

• Xtreme Series Spiral Technology - one-of-a-kind spiral cutting geometry guarantees the best possible finish along with extra-long cutting life, reducing the frequency and cost of bit replacement in demanding production environments.
• 2 + 2 Tooth Configuration (Z2+2) - the four-edge cutting arrangement provides balanced chip evacuation and smooth shearing action, resulting in cleaner cuts and reduced tearout on veneer, laminate, and solid wood surfaces.
• Solid Carbide (HW) Cutting Material - hardmetal construction delivers significantly greater hardness and heat resistance compared to standard high-speed steel bits, maintaining a sharp cutting edge through extended routing sessions on abrasive materials like MDF and chipboard.
• Dual Bearing Guide System (2 Bearings) - two precision ball bearings follow the template or workpiece edge for accurate, consistent flush trimming with minimal operator effort, reducing the risk of over-cut or edge deviation.
• 1/2" Shank Diameter - the heavy-duty 1/2" shank provides maximum rigidity and reduced vibration compared to 1/4" shank alternatives, resulting in a smoother cut and less chatter even at full 2" cutting depth.
• Right-Hand Rotation (RH) - compatible with the standard rotation direction of handheld routers, router tables, and CNC routing machines, ensuring broad machine compatibility without setup adjustments.
• 3/4" Cutting Diameter x 2" Cutting Height - the generous 2" cutting height allows flush trimming of thick stock, stacked material, or deep template profiles in a single pass, increasing efficiency on demanding workpieces.
• 4-29/64" Total Length - the extended overall length provides clearance for deep template setups and allows the bit to reach into recessed or tall fixture arrangements without interference.

Why This Product

• The Xtreme Series spiral technology is purpose-built for woodworkers and cabinet shops that need both a flawless surface finish and a bit that holds its edge through long production runs - addressing the common tradeoff between cut quality and tool longevity.
• With a full 2" cutting height and a robust 1/2" shank, this bit handles thick solid hardwood, plywood, and MDF in a single flush trim pass - eliminating the need for multiple passes or bit changes when working with heavier material profiles.
• The dual bearing design makes this bit equally effective on handheld routers, router tables, and CNC routing machines, giving shops the flexibility to use one bit across multiple setups for template routing and pattern copying work.
• The hardmetal (HW) carbide construction stands up to abrasive engineered materials like chipboard, melamine, and plastic - materials that quickly dull standard bits - making this a cost-effective long-term investment for mixed-material shops.

Frequently Asked Questions

What makes the Xtreme Series flush trim bit different from a standard flush trim bit?

The Xtreme Series uses a one-of-a-kind spiral technology that guarantees the best possible finish along with extra-long cutting life. Standard flush trim bits typically use straight flutes, while the Xtreme Series spiral geometry shears material more cleanly and maintains a sharp edge through significantly more cutting cycles - which is especially valuable in high-volume or production routing environments.

Why does this bit have two bearings instead of one?

The dual bearing guide design provides enhanced stability and more consistent contact with the template or workpiece edge throughout the cut. With two bearings, the bit tracks the reference surface more reliably, reducing the chance of the guide wandering or lifting during routing, which is particularly important when trimming tall or thick stock at the full 2" cutting height.

Is this bit compatible with a handheld router, a router table, and a CNC machine?

Yes. This flush trim bit is compatible with handheld routers, router tables, and CNC routing machines. The 1/2" shank fits the standard collet sizes found on full-size routers and CNC spindles, and the right-hand (RH) rotation matches the standard direction of these machines.

What materials can this CMT flush trim bit cut?

The hardmetal (HW) carbide construction makes this bit suitable for a wide range of materials including solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic. The Xtreme Series spiral geometry is particularly effective on abrasive engineered sheet goods that wear down standard carbide bits more quickly.
