Tork Craft MINI Router Bit 7.9MM Keyhole 3.2MM Shank TC08389

Mini Router Bit Shape: Keyhole Shank Diameter: *3.2mm Tip Diameter: *7.9mm This Mini Keyhole Router Bit is a specialized precision tool designed for woodworkers, decorators, and hobbyists who need a professional mounting solution for small-scale projects. Featuring a 7.9mm large cutting diameter and a standard 3.2mm (1/8') shank, this bit is perfectly sized for use with high-speed rotary tools and miniature router attachments.

It is the ideal choice for creating discrete, 'blind' hanging slots on the back of picture frames, small plaques, or decorative wall hangings. The unique geometry of this bit allows it to perform a two-stage cut in a single pass. It plunges into the material to create a localized entry hole and then, as it moves along the workpiece, it carves out a wider T-slotted internal chamber.

This results in a keyhole-shaped recess that securely captures the head of a screw or nail, allowing your project to hang flush against the wall without visible hardware. Because of its T-slot design, this bit is also incredibly useful for technical hobby applications beyond hanging. It can be used to create sliding tracks for adjustable jigs or to mill interlocking 'T' channels in architectural models and wooden puzzles.

The high-quality cutting edges are engineered to clear chips efficiently from the enclosed horizontal slot, which helps prevent heat buildup and ensures a smooth, snag-free finish in both hardwoods and softwoods. Built for stability and precision, the bit's balanced construction minimizes vibration even at the high RPMs required by rotary tools.

Whether you are adding a functional mounting point to a custom jewelry box or milling an internal track for a mechanical model, this mini keyhole bit provides the specialized 'hidden' joinery capabilities required for high-definition craftsmanship and professional-grade finishing.
