Annealing brass with a drill is a technique that some reloaders use as a cost-effective alternative to specialized annealing machines. While it may not provide the same level of precision and control as dedicated equipment, it can still be effective if done correctly. Here are some steps and considerations for annealing brass with a drill:

Safety Precautions:

Always wear appropriate safety gear, including heat-resistant gloves and eye protection.
Work in a well-ventilated area to avoid inhaling fumes or gases produced during the annealing process.
Equipment and Materials:

Brass cases: Ensure that the cases are clean and free from any debris or contaminants.
Drill: Use a variable speed drill with a chuck that can securely hold the brass case.
Propane torch: A handheld propane torch can be used to heat the brass case.
Annealing Process:

Secure the brass case in the drill chuck, ensuring it is held firmly but not overly tight.
Start the drill at a low speed to prevent excessive spinning or wobbling.
Apply heat to the neck of the brass case using the propane torch.
Move the torch in a circular motion around the neck of the case to distribute the heat evenly.
Heat the neck until it reaches the desired temperature, which is typically indicated by a dull red color.
Once the desired temperature is reached, stop heating and allow the case to cool naturally.
Testing for Proper Annealing:

After annealing, it is important to check the effectiveness of the process.
One method is to use a pair of small Vise-Grips to squeeze the neck of the annealed case.
Note the pressure required to deform the neck and observe if it springs back to its original shape.
Properly annealed brass should require less pressure to deform and should not spring back completely.
It is worth noting that annealing brass with a drill may not provide the same level of consistency and control as specialized annealing machines. However, with proper technique and attention to detail, it can still be a viable option for some reloaders.
