Often, we buy doors prehung in their jambs with the hinges in place. It saves time. Moreover, factory-installed hinges are highly precise and fit better with other factory-sourced fittings.

However, you can also cut your hinges and install the jambs if you wish. It’s a fairly detailed process. However, it’s cost-saving, and the acquired skills can prove invaluable down the line.

Below we discuss how to DIY-cut door hinges and review what router bit to Use for door Hinges

What Router Bit Should You Use for Door Hinges?

Ideally, you should use 1/2-inch flush trim router bits for door hinges, though you can also use straight bits with good results. It depends on many factors, including the door type and material. Generally, we recommend a 1/2-inch to 3/4-inch diameter and a 1/4-inch cutting depth.

Why are Door Hinges Recessed?

Door hinges are recessed to eliminate gaps between the frame and the door when you close the door.

Eliminating gaps is important for your security, health, hygiene, and the home’s energy efficiency. For example, it makes it more difficult for burglars to break through the door.

Additionally, it keeps out bugs and insects and prevents the loss of conditioned indoor air.

Factors to Consider When Choosing the Correct Router Bit to Mortise Door Hinges

  • Bit type: There are many types of bits, from straight bits to flush trim bits, rabbeting bits, and multi-profile bits. We recommend flush trim bits for cutting door hinges. However, straight bits are just as effective.
  • Measurements (Diameter and Depth): We recommend 1/2-inch diameter bits, though some people are happy with 3/4-inch and 1/4 models. The best cutting depth is 1/4 inches.
  • Door type: Many bits work equally well for small and large doors, regardless of the wood type. However, it helps to find something more suited to the door type.
  • Versatility and longevity: Many people want router bits with multiple applications. In that case, straight bits are more versatile than flush trim bits. Meanwhile, longevity depends on the construction material.
  • Single bit or a whole kit? Door hinge router bit kits are ideal for beginners who need to test a few options before settling on the best solution. Meanwhile, industry professionals who already know what they need can purchase a single bit; it’s more cost-effective.

How to Cut a Door Hinger Mortise with a Router Bit: Step-by-Step Guide

  1. Score around the hinge: Set the hinge on the door spot where you wish to install it. Then, holding it firmly with one hand, trace around the edges with a utility knife.
  2. Chisel the scored cut line: You need a one-inch or one-and-a-quarter-inch chisel for this step. Hold it vertically with the beveled side facing the mortise and tap gently with a hammer. Ideally, you want to cut the wood 1/8-inch deep. Repeat for the whole hinge outline.
  3. Set the router depth: The router only cuts depending on your settings. So, find out the thickness of your hinge leaves and set the router to approximately the same depth. Alternatively, loosen the depth setter, place your hinge under the setter, and tighten the screws to mark the depth. Then remove the hinge.
  4. Make the cut: Position the router on the hinge outline (created in step #1) and plunge it until you’ve cut the required depth. Repeat for all four sides of the outline, then clean up the wood shavings.

FAQs

Can you use a router to cut/mortise door hinges?

Yes, you can cut a hinge mortise using a router and hinge mortising jig. It does so with precision and uniformity of depth, resulting in perfectly seated, flush hinges. To begin cutting, clamp the jig to the door and use it to guide the router through the cut.

How do you route door hinges?

Routing door hinges is easy. You need an electric router, tape measure, and a carpenter’s pencil. Use the tape measure and pencil to measure and mark out the hinge outline. Then set the router’s depth using the depth setter, place the electric router on the outline, and begin cutting. These actions require your doors to be made of the best wood for doors.

Which is the best router bit for door cabinet door hinges?

We (and many other experts) recommend 1/2-inch router bits for cutting cabinet doors. It offers the highest stability and guarantees better performance than smaller bit sizes. To be precise, consider a half-inch flush-trim router bit. However, some people find 3/4-inch and 1/4-inch bits more suitable. It depends on the project.

How do you cut a door hinge with a Dremel?

First off, it’s true that you can use a Dremel to cut out the hinge’s housing. But, more importantly, it’s a straightforward process. First, measure and mark the outline, then adjust the Dremel’s cutting depth and wear your PPEs. After that, align the Dremel router bit with the cut marks and begin cutting.

Can you use a trim router for a hinge mortise?

Yes. A trim router with a plunge base is a good choice for cutting hinge mortises. It obviates the need to tip the router into the wood. Moreover, the guide provides smooth and evenly lined mortise sides. We especially recommend it for inlay pieces.
