Milwaukee 4932479858 Shockwave TX25 Torx25 Pack of 25 with holder

Shock Zone Geometry - designed for optimal flexibility.
Because the tip is extra hard forged it forms a perfect combination with the screw head, also reduces wear due to slipping for an unusually long life.
Made-to-measure steel - thanks to Milwaukee's special steel formula, Shockwave screw bits are optimally resistant to high impact forces
