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.
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.
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.
• 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.
• Can I use these SDS Plus cores on reinforced concrete?
They're intended for masonry and light/medium concrete with minimal steel. For frequent or continuous rebar, select a wet coring rig with 1-1/4" UNC.
• Do I need a pilot drill?
Not required for most brick/block, but a pilot adapter is helpful on smooth or coated surfaces to prevent walking.
• Dry use only?
Yes. They're engineered for dry operation. A strong vacuum setup significantly improves cutting speed and segment life.
• What's the recommended drill setting?
Rotation-only; turn the hammer action off. This preserves the diamonds, maintains edge quality, and reduces substrate micro-cracking.
• What is your MOQ and lead time?
MOQ is 10 pcs per size. Standard sizes ship fast; custom specs are available with short lead times.
