The professional IRWIN SPEEDHAMMER PLUS concrete drill bit with a 4 mm diameter and SDS-plus shank offers fast and precise drilling in concrete, masonry, and granite. Thanks to a 25% stronger carbide tip and an aggressive cutting angle, it achieves higher speed and long service life. The asymmetric flute ensures efficient dust removal and the centering tip prevents skidding at the start of the hole.
IRWIN SPEEDHAMMER PLUS is a reliable drill bit for demanding use in concrete, masonry, bricks, panels, and granite.

The body made of fully heat-treated chrome-vanadium steel (STEEL BODY) ensures maximum bending strength and longer tool life.
With its SDS-plus shank, the drill bit is compatible with all hammer drills using this system. The PGM certification confirms accuracy and quality for use with anchors. An ideal choice for professionals and DIYers who demand speed, precision, and durability.
