Milwaukee Shockwave HSS-G Tin Metal Drill Bit Set, Hex, 3-10 mm, 10-piece

Impact-resistant drill bit with a ¼″ hex shank, suitable for impact drivers.
The titanium nitride coating dissipates heat and makes the drill bit suitable for use at high speeds.
QUAD EDGE™ tip: a unique combination of a 135° split point and four cutting edges: the 135° split point allows for precise and fast drilling without walking. The four cutting edges create smaller chips to prevent heat build-up over time.
Variable drill bit geometry: for faster material ejection. Helps the tip work cooler and prevents it from burning out quickly.
Enhanced taper web: wider core towards the drill shank. Strengthens the core to increase the flute's overall durability.
