Mini Router Bit Shape: Straight Shank Diameter: Ø3.2mm Tip Diameter: Ø6.4mm This Mini Straight Router Bit is a heavy-duty essential for precision woodworking, offering a wider 6.4mm cutting diameter while maintaining a standard 3.2mm (1/8′) shank. This specific configuration is perfect for hobbyists and craftsmen using high-speed rotary tools who need to remove more material efficiently without sacrificing the agility of a miniature setup. It bridges the gap between delicate micro-detailing and standard cabinetry work, making it a versatile ‘workhorse’ for small-scale projects. The bit is expertly engineered for slotting, grooving, and plunging, producing perfectly vertical sidewalls and a clean, flat bottom. With a 6.4mm width, it is the ideal size for cutting standard-width dadoes and grooves in model furniture, or for hollowing out recessed areas for electronic components, battery compartments, and inlay materials. Because it is a plunge-capable bit, you can begin your cut anywhere on the surface of the workpiece, providing total creative freedom for internal cutouts. Beyond joinery, this 6.4mm straight bit excels at edge-trimming and surface leveling. Its larger cutting surface allows for smoother passes when squaring up the edges of thin boards or cleaning up rough cuts from a scroll saw. The high-quality cutting geometry is designed to eject wood chips rapidly, which significantly reduces friction and heat buildup, ensuring a crisp, professional finish on hardwoods, softwoods, and composite materials alike. Built for stability and durability, the bit’s balanced construction ensures minimal vibration even at high RPMs. Whether you are milling a track for a sliding lid, creating decorative geometric patterns, or performing precise cutout work for architectural models, this mini straight bit provides the robust performance and surgical accuracy required for high-definition craftsmanship.
