Do you need to drill a keyhole slot but don’t have a router? No need to worry – you can do it with just a drill and some simple tools. In this step-by-step guide, we’ll show you how to drill a keyhole slot without a router. With just a few easy steps, you’ll be able to create a perfect keyhole slot without the need for a router.

Materials and Tools

Materials And Tools

Drill: A drill is the most important tool for the job. It should have the right size and power to make the keyhole slot. It should also have a depth stop to prevent the drill bit from over-drilling.

Countersink Bit: A countersink bit is used to create the countersink for the keyhole slot.

Masking Tape: Masking tape is used to protect the work surface and help prevent slipping of the drill bit.

Marker: A marker is used to mark the center of the keyhole slot.

Wood: The wood to be drilled should be thick enough to accommodate the keyhole slot.

Screws: The screws are used to attach the wood to the work surface.

Preparing Keyhole Slot Layout

Preparing Keyhole Slot Layout

Before drilling the keyhole slot, it is important to prepare the layout. This involves marking the exact locations of the slot with a pencil or marker. To do this, first measure the width and length of the material where the slot will be drilled. Then, using a ruler, draw a rectangle with the measured dimensions. The rectangle should be slightly larger than the material if the slot is to be used for mounting.

Next, use a compass to draw two circles inside the rectangle. The circles should be the same diameter as the keyhole slot bit. The distance between the centers of the circles should be equal to the distance of the slot.

Finally, mark the center of the rectangle for easy reference. This will help you align the drill bit when drilling the slot. It is also important to mark the center of each circle, as this is where the drill bit will make contact. Once the layout is complete, it is time to move on to the next step of drilling the keyhole slot.

Tip: To ensure accuracy, use a center punch to mark the center points of the circles and the rectangle.

  • Mark the position of the keyhole slot – Make a mark at the desired position for the keyhole slot on the material’s surface.
  • Drill a holeUse a drill bit that is slightly smaller than the width of the keyhole slot to drill a hole at the marked position.
  • Create an elongated slot – With the same drill bit, increase the size of the hole by drilling at an angle to create an elongated slot.
  • Clean up the slot – Use a chisel to clean up the edges of the slot and make it look neat.

Finishing the Keyhole Slot

Finishing The Keyhole Slot

The last step of the process is to finish the keyhole slot. To do this, you will need a jigsaw or coping saw. Start by placing the saw blade into the drilled slot and cut along the edges of the keyhole slot. Make sure to cut slowly and smoothly.

Note: Do not force the saw blade into the slot as this can cause the blade to become stuck in the material.

Once the slot is cut out, use sandpaper to smooth out any rough edges. Use a piece of wood as a backer to sand the inside surfaces of the slot. This will ensure a smooth finish.

Tool Purpose
Jigsaw or Coping Saw To cut out the keyhole slot
Sandpaper To smooth out any rough edges

After the slot has been cut out and sanded, wipe down the area with a damp cloth to remove any dust and debris. Your keyhole slot is now finished and you can proceed with installing your hardware.

Ensuring the Keyhole Slot is Centred and Even

Ensuring The Keyhole Slot Is Centred And Even

To ensure the keyhole slot is centred and even it is recommended to use a template. For this, use a piece of scrap wood, or cardboard, to draw an outline of the keyhole slot onto the piece of wood you are drilling.

Using a ruler and square, draw a vertical line and a horizontal line to indicate the centre of the slot. Then draw two ‘V’ shapes at the end of the lines to mark the two ends of the slot.

Tool Purpose
Ruler To draw vertical and horizontal lines
Square To draw the centre of the slot
Scrap wood/cardboard To draw the outline of the keyhole slot

Once the template is drawn, stick it to the piece of wood you are drilling. Check the placement of the template is central, and that it is straight. Once you are happy with the template, you can start drilling.

Using a drill bit, carefully drill two holes at the two ends of the slot. Make sure these holes are the correct size and evenly spaced. Then, use a jigsaw or a circular saw to connect the two holes, creating the keyhole slot.

Keep in mind:

  • Check the template is correctly placed and straight before drilling
  • Drill two holes that are the correct size and evenly spaced
  • Connect the two holes using a jigsaw or circular saw

This is the easiest way to ensure the keyhole slot is centred and even.

Saber Saw: A saber saw can be used to cut keyhole slots as well. Use a thin saw blade and make multiple passes at the desired depth.

Drill Bit: A drill bit can be used to create a keyhole slot. Use a drill bit to make a hole at the desired depth. Then use a saw blade to cut the slot.

Chisel: A chisel can be used to create a keyhole slot. Make sure to use a sharp chisel to create a clean cut. Make multiple passes at the desired depth.

Safety Considerations

  • Use Safety Goggles: Wear safety goggles to protect your eyes from flying debris caused while drilling.
  • Use Hearing Protection: Wear hearing protection to protect your ears from the loud noise produced by the drill.
  • Use Respiratory Protection: When drilling, particles of wood, metal, and other debris can be released into the air. Wear a respirator to protect your lungs from these particles.
  • Use Gloves: Wear gloves to protect your hands from sharp edges and splinters, and to keep your hands from getting hot from direct contact with the drill.
  • Secure the Workpiece: Make sure the workpiece is firmly secured to the work surface or in a vise. This will ensure that it does not move while drilling.
  • Clamp the Drill Bit: Make sure the drill bit is firmly clamped in the drill chuck. This will prevent it from slipping and causing injury.
  • Use the Right Drill Speed: Make sure that the drill is set to the correct speed for the material being drilled. The wrong speed can cause the drill to overheat and cause injury.
