What is the RCBS 3 Way Cutter?

The **RCBS 3 Way Cutter** is a specialized reloading tool engineered for efficient and comprehensive brass case preparation. At its core, it performs three essential functions in a single, seamless operation: trimming, deburring the inside of the case mouth, and chamfering the outside of the case mouth. This integrated approach significantly reduces the time and effort required for brass preparation compared to using individual tools for each task.

The heart of the **3 Way Cutter RCBS** is the cutting head. This precisely engineered component houses the cutting blades and the guides that ensure accurate and consistent results. The cutting head is designed to work in conjunction with a case-specific pilot, which fits snugly inside the case neck. This pilot centers the case within the cutter, ensuring a square and even trim. The handle, or chuck depending on the specific model you choose, provides the leverage needed to rotate the case against the cutting head, facilitating the trimming and finishing process.

The magic of the **3 Way Cutter RCBS** lies in its unique three-way cutting action. As the brass case rotates against the cutter head, the following occurs:

Trimming: The cutting blades trim the case mouth to the desired length, ensuring uniformity across all cases. This consistent length is critical for proper headspace and consistent chambering.
Deburring: The inner blades remove any burrs or rough edges that may be present on the inside of the case mouth, left over from the trimming process. This prevents the bullet from catching or snagging during seating and ensures a smooth, consistent bullet seating depth.
Chamfering: The outer blades chamfer the outside edge of the case mouth, creating a beveled edge. This angled edge facilitates easier bullet seating, reduces the risk of damaging the bullet, and improves the concentricity of the loaded round.

The **3 Way Cutter RCBS** is designed for ease of use and precision, making it a valuable asset for reloaders of all experience levels. It’s a straightforward tool, but it is also an effective tool for precision reloading.

Step-by-Step Guide: How to Use the RCBS 3 Way Cutter

Using the **RCBS 3 Way Cutter** is a straightforward process, even for beginners. Following these steps will ensure you achieve accurate and consistent results:

Pre-Trim Preparation

Clean and Inspect Brass Cases: Before trimming, clean your brass cases thoroughly. This will remove any dirt, debris, or lubricant that could interfere with the cutting process. Inspect each case carefully for damage, such as cracks, dents, or other defects. Discard any damaged cases.
Size and Prime the Brass: The brass cases should be sized and primed prior to trimming. This ensures that the case necks are properly sized and that the primer pockets are ready to receive new primers. The sizing operation often lengthens the case, so trimming is almost always necessary.
Determine the Correct Case Length for your Load: Consult your reloading manual or other reliable sources to determine the recommended trim-to length for your chosen cartridge and bullet combination. This length is critical for achieving proper headspace and safe operation.

Setting Up the Cutter

Select the Correct Pilot for your Caliber: Choose the correct pilot for your caliber. The pilot fits inside the case neck and centers the case within the cutter. Each pilot is specific to a particular caliber or a range of calibers. Make sure you have the correct pilot for the brass you are working with.
Insert the Pilot into the Case: Insert the pilot into the case neck until it is fully seated. The pilot should fit snugly.
Adjust the Cutter Depth (if applicable): Some models of the **RCBS 3 Way Cutter** may allow you to adjust the cutting depth. If your model allows, adjust the cutter to the desired trim-to length. If not, trimming is achieved with the fixed cutting depth of the cutter.

Trimming, Deburring, and Chamfering

Insert the Case into the Cutter: Insert the case, with the pilot installed, into the **3 Way Cutter RCBS**. The case mouth should sit within the cutting head.
Apply Consistent Pressure and Rotate the Case or Handle: Apply a moderate and consistent amount of pressure to the case while rotating the handle or turning the case itself, depending on your model. This action causes the cutting head to trim the case, deburr the inside of the case mouth, and chamfer the outside of the case mouth.
Ensure the Cutter Cuts the Case Evenly: Rotate the case slowly and steadily, ensuring the cutting head makes contact with the case mouth around its entire circumference. Maintain consistent pressure throughout the process.
Remove the Case and Inspect the Trim: After trimming, remove the case from the **3 Way Cutter RCBS** and inspect the trim. The case should be trimmed to the correct length, and the case mouth should be clean, deburred, and chamfered. Check each case to make certain they are properly trimmed and prepared.

Tips and Tricks

Stubborn Cases: Occasionally, you may encounter cases that are difficult to trim. Ensure the pilot is correctly inserted and that the case neck is clean and free of obstructions. Apply slightly more pressure when rotating the case.
