Key Features

Big Hole Capacity Built to drill large holes up to 5 inches in diameter, which makes it a practical choice when standard masonry bits are too small for the job. Carbide For Concrete Carbide teeth are built to handle impact and heat in concrete, helping the bit hold up longer than standard core bits in demanding drilling work. SDS-Max Ready The Diablo DMAMXCC5060 core bit is made for SDS-Max rotary hammers, giving you the right shank style and impact stability for heavy-duty concrete drilling.

Overview

The Diablo DMAMXCC5060 5-in. x 7-in. x 12-in. SDS-Max Carbide Tipped Core Bit is a large-diameter concrete coring accessory for pros who need to open up clean holes in tough material with an SDS-Max rotary hammer. This is a coring bit designed for drilling large-diameter holes in concrete. Model Number: DMAMXCC5060. If your work calls for bigger penetrations than a standard masonry bit can handle, this is the kind of accessory that earns its spot in the truck.

The big selling point here is capacity. Diablo rates this core bit for drilling holes up to 5 inches in diameter, which makes it a strong fit for larger pass-throughs and penetrations in concrete. The 3.25-inch drilling depth gives you useful reach for common wall and slab work, while the 12-inch overall bit length gives the setup enough body for stable control in the tool.

Diablo uses carbide teeth here for a reason. In concrete drilling, heat and repeated impact are what shorten accessory life. Carbide stands up better under that abuse, which helps this SDS-Max core bit keep cutting when a lesser bit would start slowing down or wearing unevenly. Diablo also calls out off-set carbide teeth for fast, clean holes, which matters when you want the bit to start cutting decisively instead of chattering its way into the material.

This bit is also built to clear waste efficiently. The spiral flute design is there to move dust out of the hole faster, which helps keep the cutting end cooler and working more consistently. That is not a throwaway feature on a concrete coring bit. Better dust extraction means less heat buildup around the carbide teeth, smoother drilling, and less time fighting a loaded-up bit.

For starting accuracy, Diablo adds a peak point tip design to help the bit bite quickly and begin the hole aggressively. That gives you a cleaner start and helps reduce wandering at the beginning of the cut. On large-diameter holes, that first contact matters. A bit that starts clean usually drills cleaner the rest of the way through.

The one-piece, no-connector design is another practical advantage. Fewer connection points can mean better stability under impact, and Diablo specifically positions this construction for strength and extreme impact resistance. On a heavy-duty concrete accessory, that matters because it helps the bit stay solid when the rotary hammer is working hard.

Compatibility is straightforward. This is an SDS-Max shank core bit with an 18 mm shank diameter, and Diablo states it is built for maximum performance in SDS-Max rotary hammers. That makes it a purpose-built choice for users already working on the SDS-Max platform and looking for a concrete coring bit rather than a general-purpose drill bit.

Who should buy it? This bit makes the most sense for contractors and tradespeople doing regular concrete drilling where larger holes are part of the job. If you are opening holes in concrete for mechanical, electrical, plumbing, or general construction work and need an SDS-Max coring bit with carbide durability, this is the right kind of accessory. If you only drill occasional small anchor holes, it is more bit than you need. If you need repeatable large-diameter concrete holes, it is right on target.

Built to Hold Up in Concrete

This concrete coring bit is set up for the kind of work that punishes ordinary accessories. Between the carbide cutting teeth, the one-piece body, and the SDS-Max interface, it is built for impact-heavy drilling where stability and life matter.

• Carbide teeth are designed to handle heat and repeated impact in concrete.
• Spiral flute design helps move dust out faster to keep the bit cutting cleaner.
• Peak point tip supports aggressive starts for faster hole formation.

Pro Tip

When you are drilling deeper concrete holes with a large core bit like this, back the bit off periodically to let the spiral flute clear dust. It helps the carbide stay cooler and keeps the hole cutting cleaner instead of packing up.

Tool Nut's Take

Tool Nut's Take

Diablo DMAMXCC5060 5-in. x 7-in. x 12-in. SDS-Max Carbide Tipped Core Bit for serious concrete work

This is a purpose-built concrete coring bit for users who need large holes, solid SDS-Max fitment, and carbide durability instead of a lighter-duty accessory that will get chewed up halfway through the job.

• Who it's for: Contractors and tradespeople drilling larger penetrations in concrete with an SDS-Max rotary hammer.
• Why it stands out: You get 5-inch hole capacity, carbide teeth, spiral flute dust removal, and a one-piece design built for impact resistance.
• Worth knowing: This is a specialized coring bit, not a general masonry bit. It is the right call when hole size and concrete performance matter, but it is overkill for small routine drilling.

Common Questions

• What material is this core bit designed to drill? It is designed for concrete applications.
• What tool interface does it use? It uses an SDS-Max shank and is intended for SDS-Max rotary hammers.
• How large of a hole can it drill? Diablo states it is optimized to drill holes up to 5 inches in diameter.
• What is the drilling depth? The listed drilling depth is 3.25 inches.
