Milwaukee Red Hex drill bit set HSSG-TIN, 19 pcs., 1/4 in. bit shank

Impact-rated drill bits with a 1/4" hex shank for impact drivers. The titanium nitride coating dissipates heat and makes the drill bit suitable for high-speed use as well. QUAD EDGE™ tip: a 135° cutting tip and 4 cutting edges improve centering, speed up drilling starts without bit walking, and produce less drilling debris, helping prevent heat buildup. The variable flute geometry removes material from the bit faster, helping the tip stay cooler. Improved tapered web: a wider core toward the shank increases drill bit durability. Ø 2 / 2.5 / 2 x 3 / 3.5 / 2 x 4 / 4.5 / 5 / 5.5 / 6 / 6.5 / 7 / 7.5 / 8 / 8.5 / 9 / 9.5 / 10 mm.
