Kreg Concealed Hinge Jig — 35mm Cup Drilling Jig, Adjustable 3–6mm Offset for Clean Hinge Holes

If you fit European-style concealed hinges on cabinet doors, this jig is built to simplify layout and drilling while improving consistency. It combines a four-cutter carbide-tipped 35mm boring bit with an adjustable guide that supports common hinge offsets, so you can produce clean cup holes with controlled depth without a drill press. The Kreg tool is designed for cabinetmakers, remodelers, and DIYers who need precise hinge placement across single doors or full sets.

How does the jig ensure accurate 35mm cup drilling?

The Kreg jig pairs a four-flute, carbide-tipped boring bit with a stop collar and a rigid guide so each hole is the correct diameter and depth. The cutter geometry and collar prevent blowout and tear-out for smooth, properly sized hinge cups.

• Includes a four-cutter carbide-tipped 35mm bit for clean edges
• Stop collar limits depth for consistent hinge seating
• Sturdy guide holds bit perpendicular to the door face
• Designed for use with common hand drills—no press required

What hinge positions and door layouts can I set with this tool?

The jig lets you set common hinge overlay offsets (3mm–6mm) and place cups as close as 2 in (50 mm) from the door edge or anywhere farther for custom spacing. Adjustable placement supports standard cabinet proportions and one-off designs.

• Selectable offsets: 3mm, 4mm, 5mm, and 6mm
• Minimum edge distance of 2 in (50 mm) for safe cup placement
• Unlimited spacing between hinges for varied door heights
• Repeatable layout marks reduce measuring time across multiple doors

How will this jig speed up my cabinet door installation workflow?

By removing the need to mark and measure each hinge location individually, the Kreg jig cuts setup time and reduces layout errors. Use the guide and stop-collared bit to bore every cup hole to the same depth and position, so hinge mounting and door alignment become quicker.

• Repeatable drilling saves time on multi-door projects
• Simplifies hinge alignment during assembly and installation
• Eliminates guesswork—holes come out clean and consistent
• Compatible with portable drills keeps work on-site efficient

What materials and skill level does this tool work best with?

The Kreg Concealed Hinge Jig is suitable for common cabinet door materials including hardwoods, plywood, and MDF. It’s straightforward enough for motivated DIYers yet precise enough for professional shops where consistent hinge fit matters.

• Works with hardwood, plywood, MDF, and veneered panels
• Useful for both one-off repairs and production runs
• No advanced setup skills required—basic tool familiarity advised
• Hand-drill compatibility for on-site and in-shop use
