A 4-piece 90° titanium-coated countersink deburring drill bit set with a hole is a specialized tool kit designed for creating smooth, conical openings and removing sharp edges (deburring) from drilled holes. These "hole" or "cross-hole" style bits are particularly effective because the hole through the bit serves as a flute to clear away chips, preventing clogging and ensuring a cleaner finish compared to standard fluted bits.
