The BLUEROCK® 4Z1 is a high-performance handheld core drill designed for contractors who need reliable power without the bulk of a full core rig. Built for cutting 1"–4" diameter holes through concrete, masonry, asphalt, and reinforced materials, this drill delivers the torque, control, and durability required for real-world jobsite conditions.

Whether you're installing plumbing lines, electrical conduit, or HVAC systems, the 4Z1 allows you to drill clean, accurate holes quickly—without hauling a stand-mounted system.

⚡ Why Contractors Choose the 4Z1

True Portable Core Drilling
No stand required for most applications. Ideal for tight spaces, walls, and retrofit work. Faster setup than traditional rigs.
Powerful 1500W Motor
Delivers strong torque for drilling through concrete and rebar. Maintains consistent cutting performance under load.
2-Speed Gearbox for Control & Efficiency
High speed (2100 RPM) for smaller holes. Low speed (950 RPM) for high-torque drilling up to 4". Reduces stalling and extends bit life.
