Metal Bond Diamond Micro Reamers

These tools are precision-engineered tools designed for ultra-fine hole finishing, sizing, and polishing in extremely hard or brittle materials. They combine the abrasive strength of diamond with the durability of a metal bonding matrix, making them ideal for high-accuracy, small-diameter reaming work.

Key Features

• Carbide/cobalt: Metal bond securely holds the diamond particles, ensuring long life and consistent cutting.
• Diameters: Often available in micro sizes 0.020” – 0.040” for tight-tolerance applications.
• Diamond Grit: Fine to ultra-fine mesh sizes (often 400 grit and finer) for a smooth, precision finish.
• Shank Types: Typically mounted on steel, carbide, or stainless shanks for stability and low runout.
• Cooling: Designed for use with coolant or in ultrasonic-assisted machining to minimize heat and prevent workpiece damage.

Applications

• Precision Hole Sizing in hard ceramics, sapphire, quartz, and glass.
• Aerospace & Defense: For tight-tolerance holes in carbides and composites.
• Medical Devices: Machining of surgical instruments, dental tools, and implant components.
• Electronics: Micro-hole finishing in semiconductor wafers, ferrites, and PCB substrates.
• Optics: Drilling and finishing holes in lenses, prisms, and specialty glass.

Advantages

• Extremely long service life compared to resin or vitrified bonds.
• Maintains precise geometry over many cycles.
• Produces highly accurate hole diameters with minimal taper.
• Capable of working with ultra-hard and brittle materials without chipping.
• Can be custom-manufactured to exact dimensions and tolerances.
