What Is Core Cutting?
Core cutting is a precision drilling method used to create clean, round holes in concrete, RCC (Reinforced Cement Concrete), brick walls, and other masonry surfaces. A diamond-tipped drill bit, mounted on an electric or hydraulic machine, rotates at high speed — usually with water cooling — to cut through hard material without cracking the surrounding structure.
Unlike old-school hammer-and-chisel methods, core cutting is dust-minimal, low-vibration, and far more accurate. That makes it the standard choice for both residential and commercial construction in a dense, vertically-built city like Delhi, where neighbouring walls and shared structures can't afford rough handling.
If you want a side-by-side comparison of round-hole drilling versus square or rectangular openings, our detailed breakdown of Core Cutting Service versus Wall Cutting Service explains exactly when each is used.
Why Core Cutting Matters for Delhi Homes & Buildings
Delhi's building stock is a mix of old-style brick construction in areas like Old Delhi and Karol Bagh, and modern RCC-framed high-rises in Dwarka, Vasant Kunj, and Rohini. Each surface type behaves differently under drilling pressure, which is exactly why hiring an experienced, verified core cutting contractor in Delhi matters so much.
Common reasons Delhi residents and businesses need core cutting include:
- AC pipe and unit installation — round holes for split AC copper piping and drainage
- Plumbing and drainage lines — passing pipes through slabs and walls between floors
- Electrical conduits and CCTV cabling — clean openings for wiring without damaging load-bearing walls
- Exhaust fans and chimney venting — kitchen and bathroom ventilation openings
- Structural modifications — door, window, and duct openings in beams or slabs during renovation
For commercial properties — offices, malls, hospitals, and factories — core cutting is also essential for fire-safety duct work, server room cabling, and HVAC retrofits, where precision and minimal disruption to ongoing operations are critical.
Core Cutting for Residential Properties in Delhi
Homeowners across Delhi NCR most commonly request core cutting for:
- Split AC installation — a 50mm–75mm hole for refrigerant pipes and drainage
- Kitchen chimney exhaust — round openings for ducting to the outside wall
- Bathroom and water line repairs — slab cutting to access or replace pipes
- New door or window openings — wall cutting during home renovation
Because most Delhi flats share walls with neighbouring units, residential core cutting needs a contractor who understands load-bearing structures and uses wet-cutting methods to control dust and noise — particularly important in housing societies with strict renovation timing rules.
See our Slab Cutting Service page for details on floor and roof slab work specific to residential drainage and plumbing projects.
Core Cutting for Commercial Buildings in Delhi
Commercial projects in Delhi — from co-working spaces in Connaught Place to industrial units in Okhla — usually involve larger-scale or more technically demanding core cutting work:
- Beam cutting for structural modifications during office fit-outs (see our Beam Cutting Service)
- Multiple-floor riser openings for plumbing, electrical, or data cabling in multi-storey buildings
- HVAC duct openings for centralized air-conditioning systems
- Door cutting for new entry points or fire exits (see our Door Cutting Service)
Commercial jobs often need to be scheduled outside business hours to avoid disrupting operations — something a verified, professional contractor will plan for in advance.
How Much Does Core Cutting Cost in Delhi?
Core cutting prices in Delhi generally range from ₹150 to ₹800 per hole, depending on a few factors:
| Factor | Impact on Price |
|---|---|
| Hole diameter (50mm–300mm+) | Larger holes cost more |
| Material (brick, RCC, marble, stone) | RCC and reinforced concrete cost more than brick |
| Wall/slab thickness | Thicker structures take longer to cut |
| Number of holes | Bulk jobs often get discounted rates |
| Location/accessibility | Higher floors or tight access may add cost |
