Hinge Boring Bits

Precision Hinge Boring Bits for Cabinet & Furniture Manufacturing

Hinge boring bits are specialized drilling tools designed to produce accurately positioned, flat-bottomed recesses for cabinet hinges, concealed hinges, and furniture hardware.

GDP Tooling supplies carbide-tipped hinge boring bits for industrial woodworking machines, including CNC drilling centers, point-to-point boring machines, and multi-spindle drilling units.

Our selection includes Series 6017 hinge boring bits in 57 mm and 70 mm overall lengths, along with specialized cutting tools for preparing recesses for TECTUS concealed door hinges.

Series 6017 Carbide-Tipped Hinge Boring Bits

GDP Tooling’s Series 6017 hinge boring bits are designed for precision machining of hinge pockets and hardware recesses in cabinet and furniture components.

These tools feature carbide cutting edges, peripheral scoring spurs, and a center point to help maintain accurate hole positioning and produce clean edges.

The cutting geometry is particularly suitable for machining flat-bottomed recesses in solid wood, MDF, particleboard, and laminated materials.

Each Series 6017 bit features a 10 mm shank with a clamping flat and height-adjustment screw for secure mounting and accurate positioning in compatible drilling units.

57 mm Hinge Boring Bits

The 57 mm Series 6017 hinge boring bits are available in a range of cutting diameters for standard cabinet hinge and furniture hardware applications.

Available options include commonly used sizes such as 15 mm, 20 mm, 25 mm, 32 mm, 35 mm, and 40 mm.

The 35 mm diameter is particularly common for European-style concealed cabinet hinge cups.

Both right-hand and left-hand rotation configurations are available in the product range.

70 mm Hinge Boring Bits

The 70 mm Series 6017 hinge boring bits provide an alternative overall length for compatible CNC drilling machines and boring units.

Like the 57 mm versions, these carbide-tipped bits are designed for accurate hinge pocket machining and feature a 10 mm shank with a clamping flat and height-adjustment screw.

The longer configuration may be required by particular drilling unit setups or tool projection requirements.

When selecting between 57 mm and 70 mm overall lengths, verify the machine’s mounting requirements and available drilling depth.

Specialized Boring Tools for TECTUS Concealed Hinges

TECTUS concealed hinges are used in architectural doors and millwork where the hinge mechanism is designed to remain hidden when the door is closed.

Preparing the required hinge recesses demands accurate machining and tooling matched to the specified hinge geometry.

GDP Tooling supplies specialized boring tools for machining TECTUS hinge cutouts, including 12 mm, 16 mm, and 24 mm diameter configurations.

These tools feature M12 threaded connections and are available with a compatible threaded extension for applications requiring additional reach.

Because TECTUS hinge models have different installation requirements, the cutting tool diameter, recess depth, and machining arrangement must be matched to the hinge manufacturer’s specifications.

Applications for CNC Hinge Boring Bits

Precision hinge boring tools are used in a variety of woodworking applications, including:

• European-style concealed cabinet hinge cups
• Cabinet and furniture hardware recesses
• Closet and storage system manufacturing
• Architectural doors and millwork
• Concealed door hinge installations
• Repetitive CNC drilling and boring operations

The correct cutting diameter and boring depth are determined by the hardware being installed.

Right-Hand & Left-Hand Rotation

Industrial drilling and boring machines may require either right-hand or left-hand rotation cutting tools.

GDP Tooling offers Series 6017 hinge boring bits in both rotation configurations, depending on the selected diameter and overall length.

Always verify the required spindle rotation before ordering replacement tooling. Incorrect rotation can damage the cutting edges and workpiece.

Proper Mounting of Hinge Boring Bits

Series 6017 hinge boring bits feature a 10 mm shank with a flat for set-screw retention and a height-adjustment screw.

This configuration is intended for compatible industrial drilling units and boring chucks.

When mounting these tools in conventional precision collet systems, an appropriate cylindrical-shank adapter may be necessary to avoid clamping directly over the flat.

Correct mounting helps maintain concentricity, reduce vibration, and produce consistent hole quality.

Selecting the Correct Hinge Boring Bit

When choosing a hinge boring bit, consider:

• Required cutting diameter and recess depth
• Hinge or hardware manufacturer’s specifications
• 57 mm or 70 mm overall tool length
• Right-hand or left-hand rotation
• Shank dimensions and mounting method
• Workpiece material and surface finish requirements
• Compatibility with the CNC machine or boring unit

GDP Tooling provides technical assistance in selecting precision hinge boring bits and specialized concealed-hinge tooling for cabinet manufacturing, furniture production, and architectural millwork.
