MDMX 7/8" SDS-Max Quad Head Shank Bit

Our carbide-tipped drill bits are premium quality, professional-grade tools manufactured in Germany to the highest industry standards for Simpson Strong-Tie. They are designed to meet precise tolerance requirements and incorporate proprietary features that enhance durability and drilling speed, while improving ease of use. Regular and Quad Head® bit tip configurations are available.

Fits all current and older SDS-max rotohammers from Black & Decker, Bosch, DeWalt, Hitachi, Hilti, Kango, Makita, Metabo and Milwaukee.

Key Features:

Uniformly brazed carbide inserts result in longer bit life

Most bits contain a centering tip that facilitates easy spot drilling

Chromium-nickel-molybdenum steel alloy body ensures hammering quality and extended service life

Heat-treatment procedures and shot-peened finish increase surface hardness, drilling speed, reduces drill bit wear and improves resistance to bending forces

Drill bits conform to ANSI Standard B212.15

Chisel-shaped drill-bit head penetrates the material and directs concrete dust into the multi-flute spiral

Patented, high-volume, multi-flute spiral quickly channels concrete dust from the hole to improve drilling speed

4 x 90° head geometry crushes through rebar and prevents sticking in reinforced concrete

Quad-Head Feature:

All the features of single cutter bits and the quad-head dual-cutter are designed to improve durability and drilling speed. The high-volume, double-helix design of the quad-head bit comes with the patented, high-performance, reinforced core flute to maximize energy transfer.
