    25mm x 57mm Hinge Boring Bit, Right Hand, 10mm Shank

    Description

    25mm Hinge Boring Bit For Clean Hinge Cups

    25mm hinge boring bit is a dedicated cutting tool for creating 25mm holes for hinge cups, so hinge mortises stay consistent across doors and panels. This Amana Tool bit is a router-bit-class boring cutter, giving cabinet shops and serious DIY users a focused solution for hinge work. The bit has a 57mm length, which supports deeper boring in typical furniture or cabinet components where a 25mm hole is required. The right hand cutting design aligns with right hand spindle rotation on standard boring machines, helping the bit track true through the cut. As a 25mm x 57mm hinge boring bit, it is sized for repeated use on hinge layouts that call for a 25mm diameter, keeping layout and drilling setups predictable from cabinet to cabinet.

    Key Hinge Boring Details That Support Workflow

    • The 25mm diameter directly matches common 25mm hinge cup bores, so once the layout is set on your workpiece, this bit maintains that diameter for uniform hinge seating from door to door.
    • The 57mm long design provides working length for boring into standard cabinet or furniture stock, giving room for the bit to clear chips while reaching the full depth of a typical hinge cup hole.
    • The right hand configuration matches right hand spindle rotation on typical boring equipment, helping the cutting edges engage the material correctly for a smoother hole and more stable hinge alignment.
    • The 10mm shank for boring machines offers a defined mounting interface, so shops using 10mm chucks can secure the bit in the spindle without adapters designed for other shank sizes.
    • The drill presses application with 3/8 inch shank means this hinge boring bit can also be used on drill presses, tying into common 3/8 inch chucks found in many woodworking setups.

    Mounting And Machine Use For This Boring Bit

    This 25mm x 57mm hinge boring bit is described for use with boring machines, so it fits into workflows that rely on dedicated boring lines for cabinet production. The 10mm shank gives a defined interface for those boring machines that accept 10mm shank tools, promoting a secure grip during repetitive hinge hole drilling. The application statement also references drill presses with a 3/8 inch shank, indicating that this bit can be adapted to drill press use where 3/8 inch chucks are standard. That flexibility allows shops to apply the same 25mm hinge boring geometry across different machines, keeping hinge hole sizing and appearance consistent whether the work is handled on a boring machine or a drill press station.

    Using This Amana Tool Bit In Real Projects

    Where This 25mm Hinge Boring Bit Performs Best

    This Amana Tool 25mm x 57mm hinge boring bit fits into cabinet, furniture, and casework operations that rely on 25mm diameter hinge cups. In a boring machine with a 10mm shank interface, the bit works along line-boring or dedicated hinge boring heads where repetitive 25mm bores are required. The right hand cutting orientation pairs with right hand rotation on these machines, providing a predictable cutting path into cabinet doors, end panels, and face-frame components. When used with a drill press equipped for a 3/8 inch shank, the bit brings the same 25mm hinge cup capability to a single-spindle setup, so small shops or job-site workflows can still produce 25mm hinge bores matching shop standards.

    Details That Help Achieve Repeatable Hinge Alignment

    The defined 25mm diameter on this hinge boring bit gives installers and fabricators a fixed reference for hinge cup sizing, which supports repeatable alignment between doors and frames over multiple pieces. Its 57mm length provides the reach to bore into common door thicknesses while allowing the cutting section to clear waste as the hole is formed, which helps maintain the geometry of the 25mm bore. The 10mm shank interface on boring machines keeps the tool seated firmly in the spindle, supporting consistent centerlines and hole depths when drilling a run of doors. With the drill press application at 3/8 inch shank, the same bit geometry supports hinge boring on different equipment, so hole placement and size remain stable even when production is split between shop machines and drill press operations.

    Common Questions About This Hinge Boring Bit

    What size hinge cup hole does this bit drill?

    The 25mm x 57mm hinge boring bit drills a 25mm diameter hole, which matches hinge cup applications that call for a 25mm bore in cabinet or furniture components.

    Which machines can use this 25mm hinge boring bit?

    The hinge boring bit is designated for boring machines with a 10mm shank and drill presses with a 3/8 inch shank, so it serves both dedicated boring equipment and drill press setups.

    How does the 57mm length help in hinge boring?

    The 57mm length provides working reach to form a full 25mm hinge cup hole in typical cabinet or door stock while allowing chip evacuation during the boring cycle.

    What does right hand mean on this hinge boring bit?

    Right hand on this hinge boring bit indicates it is designed for right hand spindle rotation, matching common boring machines for accurate and stable hinge cup drilling.

    What is the role of the 10mm shank on this bit?

    The 10mm shank provides a standardized mounting interface for boring machines that accept 10mm tooling, supporting secure clamping and repeatable hinge hole positioning.

    Who manufactures this 25mm hinge boring bit?

    This 25mm x 57mm hinge boring bit is manufactured by Amana Tool, aligning it with Amana Tool router bits and boring tools used in woodworking applications.

    Select This Bit For 25mm Hinge Cup Work

    The 25mm hinge boring bit, with its 25mm diameter and 57mm length, serves hinge cup drilling tasks where a consistent 25mm bore is required. Its right hand design works with right hand rotating boring machines, while the 10mm shank specification ties into machines built around 10mm tooling. The drill presses application with 3/8 inch shank extends that same hinge boring geometry to drill press stations. For cabinet and furniture projects that rely on 25mm hinge cups, this Amana Tool bit provides a focused boring solution available through Wurth Baer Supply.
