Diamond Core Drill Bits - Esch Muscle Bits™ Diamond Wet Bits - 3/8" - 28"

Esch Muscle Bits™ – Diamond Wet Core Drill Bits for Concrete & Asphalt

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™?

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.

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.

Muscle Bits™ are made for heavy-duty use and built to handle a wide range of core drilling jobs—from structural concrete to pavement coring. If you need to drill clean, precise holes, these bits won’t slow you down.

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
• Asphalt and pavement testing
• Electrical conduit installation

Esch Muscle Bits™ deliver the cutting speed and durability pros count on every day. If you need help choosing the right size or setup for your job, contact our team—we’ve got your back.
