How to Drill and Tap a Shotgun

Drilling and tapping a shotgun is a relatively simple process, but it is important to do it correctly in order to avoid damaging your firearm. In this article, we will walk you through the steps involved in drilling and tapping a shotgun, from choosing the right tools and materials to completing the job safely and effectively.

We will also provide some tips on how to avoid common mistakes, and we will discuss the different types of taps and dies that are available. By following these instructions, you can easily drill and tap your shotgun so that you can add a scope or other accessories.

What You Will Need

Before you begin drilling and tapping your shotgun, you will need to gather the following materials:

  • A drill press
  • A tap and die set
  • A center punch
  • A hammer
  • A vise
  • A file
  • A lubricant
  • Safety glasses

Steps

1. Choose the right spot to drill. The first step is to choose the right spot to drill the hole for your tap. The best place is usually on the side of the receiver, just in front of the trigger guard.
2. Mark the spot. Once you have chosen the spot, use a center punch to mark the center of the hole.
3. Drill the hole. Use a drill bit that is slightly smaller than the tap you will be using. Drill the hole slowly and carefully, making sure not to go all the way through the receiver.
4. Tap the hole. Once the hole is drilled, use a tap to thread the hole. Start by using a tap that is slightly smaller than the final size of the thread. Work your way up to the final size, using a different tap for each size.
5. Clean the hole. Once you have finished tapping the hole, use a file to clean up any burrs or rough edges.
6. Lubricate the threads. Before you install your scope mount or other accessory, apply a small amount of lubricant to the threads. This will help to prevent the threads from binding.
7. Install the accessory. Now you are ready to install your scope mount or other accessory. Follow the manufacturer’s instructions for installation.

Tips

  • Be careful not to drill the hole too deep. If you drill the hole too deep, you could damage the receiver.
  • Use a lubricant to help prevent the tap from binding.
  • Work slowly and carefully when drilling and tapping the hole.
  • Make sure to clean up any burrs or rough edges after you have finished tapping the hole.
  • Follow the manufacturer’s instructions for installing your scope mount or other accessory.

    Step Tools Instructions
    1. Drill press
    1. Clamp the barrel into the drill press vise.
    2. Drill a pilot hole through the barrel at the desired location.
    3. Drill the tap hole to the desired depth.
    2. Tap wrench
    1. Thread the tap into the tap hole.
    2. Turn the tap clockwise until it is fully threaded into the barrel.
    3. Back the tap out of the barrel and clean it with a tap brush.
    3. Blue Loctite
    1. Apply a small amount of Blue Loctite to the threads of the tap.
    2. Thread the tap back into the tap hole.
    3. Turn the tap clockwise until it is snug against the barrel.

    Drilling and tapping a shotgun is a relatively simple process, but it is important to take the necessary precautions to ensure that you do it safely. This guide will walk you through the steps of drilling and tapping a shotgun, so that you can do it yourself with confidence.

    Tools and Materials

    The following tools and materials are required for drilling and tapping a shotgun:

    • Drill
    • Tap
    • Drill bits
    • Tap wrench
    • Cutting oil
    • Safety glasses
    • Protective gloves

    Preparation

    Before you begin drilling and tapping your shotgun, it is important to take the following steps to prepare the area:

    1. Clean the area where you will be drilling and tapping. This will help to prevent debris from getting into the threads of the tap.
    2. Mark the location of the hole with a center punch. This will help you to drill the hole in the correct location.
    3. Apply cutting oil to the drill bit. This will help to lubricate the bit and prevent it from overheating.

    Drilling the Hole

    1. Using a drill bit that is slightly smaller than the tap, drill a hole in the shotgun.
    2. Be sure to drill the hole at a right angle to the surface of the shotgun.
    3. Drill the hole until it is deep enough to accommodate the tap.

    Tapping the Hole

    1. Once the hole is drilled, it is time to tap it.
    2. Insert the tap into the hole and start turning it clockwise.
    3. Apply pressure to the tap as you turn it.
    4. Continue turning the tap until it is fully threaded into the hole.

    Cleaning the Threads

    Once the tap is fully threaded into the hole, it is important to clean the threads.

    1. Use a tap cleaner to remove any debris from the threads.
    2. Be sure to clean the threads thoroughly to prevent them from becoming clogged.

    Drilling and tapping a shotgun is a relatively simple process, but it is important to take the necessary precautions to ensure that you do it safely. By following the steps in this guide, you can drill and tap your shotgun with confidence.

    Here are some additional tips for drilling and tapping a shotgun:

    • Use a drill press if possible. This will help to ensure that the hole is drilled straight and at a right angle to the surface of the shotgun.
    • Use a tap wrench to turn the tap. This will help to prevent the tap from slipping and damaging the threads.
    • Apply pressure to the tap as you turn it. This will help to ensure that the tap is properly threaded into the hole.
    • Clean the threads thoroughly after you are finished. This will help to prevent them from becoming clogged.

    By following these tips, you can drill and tap your shotgun safely and successfully.

    3. Drilling the Hole

    Drilling the hole for the barrel threads is a critical step in the shotgun assembly process. If the hole is not drilled correctly, the barrel will not be properly aligned with the receiver and the shotgun will not function properly.

    To drill the hole, you will need the following tools:

    • A drill press
    • A drill bit that is the same size as the threads on the barrel
    • A center punch
    • A machinist’s square
    • A tap handle
    • A tap

    Instructions:

    1. Clamp the receiver in the drill press vise.
    2. Use the center punch to mark the center of the hole.
    3. Drill a pilot hole using a drill bit that is slightly smaller than the tap.
    4. Use a tap wrench to turn the tap clockwise into the hole.
    5. Apply light pressure to the tap and turn it slowly.
    6. Back the tap out frequently to clear the chips.
    7. Continue tapping until the tap is fully engaged in the hole.

    Tips:

    • Use a slow speed and light pressure when drilling the hole.
    • Stop frequently to clear the chips from the hole.
    • Do not force the drill bit if it starts to bind.
    • Make sure that the tap is properly aligned with the hole.
    • Back the tap out frequently to clear the chips.
    • Continue tapping until the tap is fully engaged in the hole.

    Troubleshooting:

    • If the hole is not drilled straight, the barrel will not be properly aligned with the receiver and the shotgun will not function properly.
    • If the tap is not properly aligned with the hole, the threads will not be cut correctly and the barrel will not be able to be screwed into the receiver.
    • If the tap is forced into the hole, it will break and the hole will have to be redrilled.

    Drilling the hole for the barrel threads is a critical step in the shotgun assembly process. By following these instructions, you can ensure that the hole is drilled correctly and the shotgun will function properly.
