Milwaukee metal drill bit set Shockwave HSS-G Tin, Hex, 2-10 mm, 19-piece

Impact-resistant drill bit with a ¼″ hex shank suitable for impact drivers.
Titanium nitride coating dissipates heat and makes the drill bit suitable for use even 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. Four cutting edges create smaller chips to prevent heat build-up for a longer time.
Variable drill working part geometry: for faster material ejection. Helps the tip to work cooler and prevents it from burning out faster.
Enhanced tapered web: wider core towards the drill shank. Strengthens the core to increase the overall durability of the flute.
