1/8″ Carbide Ball Cutter – Plunger Tube Countersink Tool

1/8″ Carbide Ball Cutter – Plunger Tube Tool

This 1/8 inch carbide ball cutter is the ideal tool for preparing the proper countersink before staking a 1911 plunger tube. It allows you to create a clean, controlled recess so the plunger tube legs seat correctly and stake securely into the frame.

First, the cutter is made from 100% solid carbide, which provides exceptional hardness and wear resistance. Because of this, it maintains a sharp cutting edge even when used on tough carbon steel or stainless steel frames. As a result, you get consistent results without rapid tool wear.

Next, the single‑pattern cutting flute gives you excellent control during the cut. This design reduces chatter and helps prevent over‑cutting, which is critical when working on thin frame walls. In addition, the ball profile produces a smooth, properly shaped countersink that supports strong, even staking.

Furthermore, the 1/8″ size is ideal for 1911 plunger tube work. It allows precise material removal exactly where needed, helping ensure proper tube alignment and long‑term retention. Because the cut is clean and uniform, the plunger tube seats flush and stakes securely.

Whether you are performing professional gunsmithing work or refining a custom 1911 build, this carbide ball cutter belongs in your toolbox. Proper plunger tube preparation is critical for reliability—and this tool helps you do it right the first time.
