Colony stocks a wide variety of hammer drills. All these drills have two modes: hammer and drill only, making them quite versatile. They are suitable for drilling in concrete and masonry while using carbide bits, and can be used with steel and wood bits as a regular drill. Hammer drills work particularly well in brick and block, and when using concrete screws. However, if you are drilling solid concrete, we recommend using a “rotary hammer” (See Pages 175-186). Please note that in our product descriptions, “BPM” means “blows per minute.”
