Mini Router Bit Shape: Straight Shank Diameter: Ø3.2mm Tip Diameter: Ø3.2mm This Mini Straight Router Bit is a fundamental precision tool designed for woodworkers, model makers, and hobbyists who require clean, narrow cuts on a small scale. Featuring a 3.2mm cutting diameter and a matching 3.2mm (1/8′) shank, this bit is perfectly balanced for use with high-speed rotary tools and miniature router attachments. Its slim, uniform profile makes it an essential ‘utility’ bit for any micro-woodworking toolkit where standard-sized cutters are too bulky. The bit is specifically engineered for slotting, grooving, and plunging into a wide variety of materials. Because the cutting diameter matches the shank size, it allows for deep, narrow channels with perfectly vertical sidewalls and a flat bottom. This makes it the ideal choice for cutting out custom inlay recesses, milling channels for small sliding lids, or creating precise mortise-and-tenon joints for architectural models and dollhouse furniture. Beyond decorative joinery, this straight bit excels at edge trimming and cutout work. When used with a straight-edge guide or a template, it can easily profile the edges of thin wood sheets or plastic laminates. The high-speed steel or carbide-tipped construction (depending on your specific grade) is optimized to clear chips quickly, reducing the risk of heat buildup and ensuring a smooth, burn-free finish on both hardwoods and softwoods. Designed for maximum control, the bit’s geometry provides a stable cutting experience even at high RPMs. Whether you are freehand engraving, milling a track for a miniature sliding door, or simply cleaning up a rough edge, this mini straight bit offers the surgical accuracy needed for high-definition projects. Its versatility and simple, effective design make it one of the most frequently used bits for detailed craft and repair work.
