Concrete Core Drill Bit With SDS Plus Shank And Center Guide
Built for rotary hammers with an SDS Plus chuck, these dry diamond core bits deliver fast penetration and clean edges in clay brick, calcium silicate brick, lightweight block (AAC), and light/medium-hard concrete with minimal steel. The direct SDS Plus shank ensures stable torque transfer without adapters, while laser-welded segments and open U-slots keep cutting speed high and temperatures under control. Trusted by contractors who value consistent results and predictable cost per hole.
Features:
Efficient & Smooth Cutting: comprising premium aluminum alloy components, and high-quality diamond grits ensure a longer coring life.
Engineered For Exact Fitting: compatible with most concrete core drill devices.
Humanized Structure: featuring chip removal holes, highly regular saw teeth, and concentric axes design.
Versatile Applications: widely used in installing air conditioners, pipes, stair railings, highways, airports, and other conditions

SDS Plus rigs excel at small-to-medium penetrations where mobility matters. Typical use cases include HVAC sleeves through brick/block, plumbing and cabling passes in interior partitions, and retrofit openings in lightweight concrete. For jobs with frequent, continuous rebar engagement or large diameters on structural concrete, step up to a coring rig with 1-1/4″ UNC and wet cooling. For everything else in the masonry category, these SDS Plus cores keep your crew fast and tidy.
Selection & Bond Guide
Choosing the right bond ensures the bit stays sharp and productive through the full run: in abrasive block or AAC, a hard bond slows wear; in medium-hard brick and mixed masonry, a medium bond balances speed and life; in denser masonry or occasional aggregate pockets, a soft bond refreshes diamond exposure to maintain cutting rate. Whenever possible, size your diameter with 3–5 mm clearance over the sleeve/pipe OD to reduce cutting load on handheld hammers.
Compatibility & Accessories
Use with any rotary hammer featuring an SDS Plus chuck, set to rotation-only. A removable pilot adapter helps start holes on glossy tile-faced brick or paint; quick extensions support deeper passes in thicker walls. Pair with a HEPA vacuum (or hollow-shank adapter where applicable) to control silica dust, improve visibility, and extend segment life.
Safety & Use Notes
• Always disable hammering; percussion can glaze segments and damage the bond.
• Keep the bit perpendicular, apply steady feed—don’t pry or side-load.
• Use dust extraction and wear a P3/N100 respirator, eye/ear protection, and gloves.
• If rebar is encountered, reduce feed and allow cooling; sustained rebar drilling will reduce service life.
• Between holes, free-spin the bit briefly to clear dust and help cooling.
FAQs
• Can I use these SDS Plus dry core bits on reinforced concrete?
They are primarily designed for masonry and light-to-medium concrete with minimal reinforcement. For frequent or continuous rebar drilling, a wet coring rig with 1-1/4″ UNC and water cooling is the better choice.
• Do I always need a pilot drill?
Not for standard brick and block work. However, a pilot adapter is very helpful on very smooth, glazed, or coated surfaces (like tile-faced brick) to prevent the bit from walking when starting the hole.
• Are these bits strictly for dry use?
Yes, they are engineered for dry operation. Using a strong vacuum dust extraction system significantly improves cutting speed, keeps the work area clean, and helps prolong segment life.
• What drill settings should I use?
Use rotation-only mode. Turn off hammer action to protect the diamonds, maintain cleaner hole edges, and reduce micro-cracking in the material.
• What is your MOQ and lead time?
The minimum order quantity is 10 pcs per size. Standard sizes are available with short lead times, and custom dimensions can be produced according to your project schedule.
