Built for serious core drilling, Esch Muscle Bits™ are high-performance diamond core drill bits designed for wet drilling through concrete, asphalt, and other tough materials. These bits are engineered with precision-cut, diamond-infused segments that power through reinforced surfaces with speed, accuracy, and long life.

Why Muscle Bits™?

Fast, Clean Core Drilling

Our diamond segments are made with performance-enhancing diamonds that cut faster and cleaner in concrete, even with rebar. Whether you're coring slabs, walls, or asphalt surfaces, Muscle Bits™ give you consistent, efficient results.

Wet Drilling Advantages

Designed for wet core drilling, these bits stay cooler and last longer. Water helps reduce friction and controls dust, which is a major benefit for indoor jobs or work sites with dust regulations.

Available in diameters from 3/8 to 28", with standard threaded connections to fit most core rigs.

Applications:

• Coring concrete walls, floors, and slabs
• Utility and plumbing pipe access
