With this 90-degree countersink, you can easily countersink holes in various components. Especially with the advent of 1.2mm thin steel chassis in the 1:10 on-road category, it has sometimes become necessary to countersink holes in other aluminum parts (e.g., bulkheads, motor mounts, etc.) so that the screws fit better from below and can be tightened securely.

Of course, you can also use the MR33 countersink on carbon fiber parts and other materials. The countersink is comfortable to hold, robust, and durable, but naturally, it can become dull after excessive use.
