What Is Core Cutting and Why Does It Matter?
Core cutting — also known as concrete core drilling or diamond core drilling — is the process of making precise circular holes or cuts through concrete, RCC slabs, stone, asphalt, or masonry structures. A rotating diamond-tipped drill bit removes a cylindrical core from the surface, leaving a clean, smooth, circular opening of exactly the diameter required.
This method is widely used in civil engineering and construction because it does not cause structural cracks, vibration damage, or surface chipping. Unlike conventional jackhammers or breakers that can compromise the integrity of the surrounding concrete, core cutting is a minimally invasive, dust-controlled, and highly accurate technique.
When Is Core Cutting Needed?
- Installing new plumbing pipes through concrete floors or ceilings
- Creating openings for electrical conduits, AC ducts, or exhaust pipes
- Fixing drainage outlets in bathrooms and kitchens
- Obtaining concrete core samples for laboratory quality testing
- Making cable routing holes in walls or slabs
- Creating anchor bolt holes in foundation structures
- Road cutting for utility pipe laying or repair
- Adding ventilation or fresh-air ducts in existing buildings
In Sitamarhi, with rapid residential and commercial construction activity, core cutting demand has grown significantly — and our team is ready to serve projects of every scale.
Our Core Cutting Services in Sitamarhi
We offer a complete range of core cutting and core drilling solutions for residential, commercial, industrial, and government construction projects across Sitamarhi.
RCC Slab Core Cutting
RCC (Reinforced Cement Concrete) slabs are among the most common surfaces requiring core cutting. We drill clean holes of diameters ranging from 25 mm to 600 mm through multi-story building slabs for plumbing stacks, drainage lines, fire suppression pipes, and electrical conduit bundles. Our diamond bits handle even heavily reinforced slabs with rebar grids without damaging the structural steel.
Wall Core Cutting & Drilling
Whether it is a brick wall, hollow block wall, or an RCC shear wall, we cut precise openings for AC pipe sleeves, kitchen exhausts, CCTV camera brackets, and fire alarm conduits. Our wall drilling rigs can be set up in confined indoor spaces with minimal dust thanks to water-cooling and vacuum systems.
Floor Core Cutting for Plumbing & Drainage
New bathroom fit-outs and kitchen renovations regularly require floor core cutting for drain traps and P-traps. We drill accurately positioned holes in floor tiles, screeds, and the concrete slab beneath — all without disturbing adjacent tiles.
Road & Pavement Core Cutting
For NHAI, PWD, or municipal infrastructure projects in Sitamarhi district, we provide road core drilling to extract cylindrical samples for bitumen testing, load-bearing assessment, and thickness measurement. We also cut asphalt roads for underground cable or pipe laying work.

Technology We Use – Diamond Core Drilling Equipment
Our Sitamarhi team uses modern, industry-standard diamond core drilling machines that comply with BIS and international construction quality norms.
Equipment in Our Fleet:
- Rotary diamond core drilling rigs (single-speed and variable-speed)
- Wet-cut diamond core bits (25 mm to 600 mm diameter range)
- Dry-cut vacuum-assisted bits for enclosed or sensitive areas
- Walk-behind road core cutting machines
- Wall-mounted drilling rigs with vacuum anchor pads
- Water recycling and slurry collection systems for mess-free operations
Why Diamond Bits? Diamond-tipped core bits cut through the hardest aggregates, steel rebar, and high-grade concrete grades (M25, M30, M40, and above) without generating heat cracks or stress fractures in the parent structure. They maintain perfect circular geometry from the first millimetre to the last.
Step-by-Step Core Cutting Process We Follow
Understanding our work process helps you plan your project better and set realistic timelines.
Step 1 – Site Survey and Marking Our technician visits your site, reviews structural drawings (if available), and identifies the safest cutting zones. Rebar locations may be checked with a rebar scanner/cover meter before drilling.
Step 2 – Machine Setup and Anchoring The drilling rig is anchored securely to the surface using chemical anchors or vacuum pads. Misalignment at this step can ruin the cut, so we take extra time here.
Step 3 – Water Connection and Safety Check For wet-cut operations, water cooling is connected to the core bit. The work area is cordoned off, and workers wear PPE including safety glasses, gloves, and ear protection.
Step 4 – Core Drilling The diamond bit is engaged at low RPM initially, then ramped up once it is seated. Steady, controlled pressure is applied throughout. Our operators are trained to read bit feedback and avoid rebar jamming.
Step 5 – Core Extraction Once drilling is complete, the cylindrical core is carefully extracted. For quality testing purposes, this core is labelled and preserved. Otherwise, it is safely removed and cleared from the site.
Step 6 – Hole Finishing and Cleanup The drilled hole is checked for diameter accuracy and perpendicularity. Slurry and water are collected and cleared. The work area is left clean.
Total time per hole: Depending on slab/wall thickness and diameter, a standard 110 mm hole through a 150 mm slab typically takes 20–40 minutes from setup to cleanup.

Core Cutting FAQs – Sitamarhi
1. What is core cutting in construction?
Core cutting is a method of drilling precise circular holes through concrete, RCC slabs, walls, or roads using a rotating diamond-tipped bit. It is used for plumbing, electrical, drainage, and ventilation installations. The process is clean, accurate, and does not damage surrounding surfaces.
2. How much does core cutting cost in Sitamarhi?
Core cutting prices in Sitamarhi typically range from ₹350 to ₹3,500 per hole depending on the diameter, concrete thickness, and access conditions. For accurate pricing, contact us on 7009679903 for a free site-specific quote.
3. Is core cutting safe for existing buildings?
Yes, diamond core cutting is one of the safest methods for creating openings in existing structures. It generates no impact vibration, minimises dust with water cooling, and does not cause cracking in adjacent concrete when done by a trained operator.
4. How long does it take to cut one hole?
A standard 110 mm hole through a 150 mm thick slab takes approximately 20–40 minutes including setup and cleanup. Larger diameters or thicker surfaces take longer. Multiple holes on the same site are completed progressively and efficiently.
