Hinge Boring Bits

Hinge boring bits (Euro hinges) drill the large, shallow cup holes used for concealed cabinet hinges.  Precision ground cutting edges produce clean pockets in solid wood and composite boards.

What are hinge boring bits used for?
Hinge boring bits are designed to drill clean, flat-bottomed holes specifically for concealed (Euro-style) cabinet hinges, such as 35 mm cup hinges. They're ideal for:

• Kitchen, bathroom, and wardrobe cabinet installations

• Furniture making and carpentry

• Hinge mounting in MDF, chipboard, plywood, and hardwood
  These bits provide accurate depth and diameter needed for a perfect hinge fit.

How are hinge boring bits different from Forstner bits?
While they look similar, hinge boring bits are:

• Optimized for 26–40 mm hole diameters (most commonly 35 mm)

• Often used with boring jigs or CNC setups for exact hinge cup alignment

• Designed for fast, clean cuts in laminated boards, chipboard, and MDF
  They usually feature tungsten carbide tips for longevity and precision, especially when drilling coated or abrasive materials.

What should I consider when choosing a hinge boring bit?
Consider the following:

• Bit diameter – the most common is 35 mm (standard for Euro hinges)

• Shank size – ensure compatibility with your drill press, boring machine, or jig

• Material –

  • Tungsten carbide-tipped (TCT) for durability in laminates

  • HSS for general woodworking

• Depth control – use a stop collar or jig to avoid over-drilling
  These bits are best used with drill presses or jigs to ensure repeatable, clean hinge recesses.
