Best Hex Long Drill Bits in 2026

Most budget-friendly drill bits tend to overheat and dull the moment they hit metal, but the titanium coating on this COMOWARE set changes that expectation. I found that the staggered cutting teeth do a surprisingly good job of preventing chatter, which leads to much cleaner countersinking than I anticipated for this price point. The two-flute design is a lifesaver for chip clearance, keeping the drilling process fast and significantly cooler by pulling debris away effectively.

The two-flute spiral design handles chip removal efficiently, keeping the hole clear and the heat down. Because these feature a 1/4-inch hex shank, they are specifically optimized for use with an impact driver rather than a standard drill. I also really appreciated the laser-engraved numbers.
