Which type of drill bit is effective for drilling through case hardened receivers?

The most effective type of drill bit for drilling through case hardened receivers is the carbide drill bit. Carbide is known for its exceptional hardness and durability, allowing it to withstand the intense wear and heat generated when drilling through tough materials, including those that have been case hardened. Case hardening enhances the surface hardness of metal components, making them much harder than the core material. This increased surface hardness requires a drill bit that can maintain its cutting edge under challenging conditions, which carbide can do effectively.

Carbide drill bits also tend to have better resistance to heat, reducing the likelihood of drill bit failure during extended drilling tasks. This hardness ensures that carbide bits can penetrate through casings without dulling as quickly as other materials might. Hence, when working with case hardened receivers, carbide is the preferred choice thanks to its ability to tackle tough materials efficiently.
