Kalkaji is a mix of densely packed DDA flats, group housing societies, small commercial units, and an active industrial belt nearby — and that combination means core cutting jobs here range from a single AC pipe hole in a third-floor flat to multiple slab cuts in a small manufacturing unit. If you're looking for a core cutting service in Kalkaji that actually understands this variety, you've landed on the right page.
We regularly work across Kalkaji's residential blocks, the shops near Kalkaji Mandir market, and several units inside Kalkaji Industrial Area where machine foundation drilling, ducting cuts, and structural sampling come up far more often than in a purely residential locality. A flat in a DDA society needs careful, low-noise cutting to avoid disturbing neighbours sharing the same building, while a factory unit might need a larger diameter cut for ventilation or pipeline access — both need the right machine, the right bit, and an operator who knows the difference.
This page walks you through our complete process, equipment, pricing, safety standards, and the questions Kalkaji residents and business owners ask us most before booking a core cutting job.
What Is Core Cutting and How Is It Different From Breaking a Wall?
Core cutting is a precision drilling method that uses a diamond-tipped rotary bit to cut smooth, accurately-sized holes through concrete, brick, or stone. Compared to traditional hammer-and-chisel breaking, it doesn't create random cracks, doesn't generate as much rubble, and gives you an exact hole size every single time — whether that's a 1-inch cable hole or an 8-inch ducting opening.
This matters in a place like Kalkaji where buildings are close together, walls are often shared between flats in the same block, and any uncontrolled vibration can travel into a neighbour's unit.
Why Kalkaji Properties Often Need Specialised Core Cutting
- DDA flats and group housing societies have shared walls and slabs between units, requiring low-vibration cutting
- Kalkaji Industrial Area units often need larger diameter cuts for machinery, exhaust ducting, or pipeline routing
- Shops near Kalkaji Mandir market need quick turnaround to avoid losing business hours
- Older buildings may have brick masonry that behaves differently from modern RCC under a drill
Typical Reasons People Book Core Cutting in Kalkaji
- Split AC and window AC pipe installation in flats
- Bathroom and kitchen plumbing line installation or repair
- Sewer and drainage pipe connections on ground floor or basement units
- Electrical wiring and conduit routing between floors
- Exhaust fan, chimney, or ventilation duct openings in shops and small factories
- Water tank inlet/outlet pipe connections on terraces
- Machine foundation anchor holes in industrial units
- CCTV, internet, and DTH cable routing through external walls
Core Cutting Services We Provide in Kalkaji

Slab and Floor Core Cutting
Used for plumbing risers and electrical shafts running between floors in multi-storey group housing buildings across Kalkaji.
Industrial Core Cutting for Ducting and Machinery
Larger diameter cuts for exhaust ventilation, pipeline access, and machine foundation work, commonly needed in Kalkaji Industrial Area units.
RCC Beam and Column Drilling
For anchor bolting and structural fixture mounting, always carried out only after a basic load-bearing assessment.
Basement and Ground Floor Cutting
For drainage and plumbing access in basement storage or ground-floor commercial spaces near the market area.
Core Sampling for Structural Testing
Used by structural engineers to extract concrete cores for strength testing before renovation or floor-addition work on older buildings.
Our Core Cutting Process, Step by Step
- Site Visit and Inspection – We check the wall or slab thickness, construction material, and overall layout of your Kalkaji property or unit.
- Utility and Rebar Scanning – Before marking any cut, we scan for hidden electrical wiring, water pipes, and steel reinforcement.
- Precise Marking – Cutting points are marked accurately, with extra care taken on shared walls between adjoining flats.
- Machine Setup and Stabilising – The core cutting rig is mounted securely to keep the cut straight and avoid drift.
- Wet Diamond Cutting – Water-cooled diamond bits keep dust under control and give a smoother, more accurate cut edge.
- Immediate Cleanup – Concrete cores, slurry water, and debris are cleared right after cutting so the space is usable again quickly.
- Quality Check – We verify hole diameter, alignment, and edge finish before considering the job complete.
- Final Handover – The site is left clean, with no leftover dust, water marks, or debris.

Frequently Asked Questions
1. What is the cost of core cutting services in Kalkaji?
Core cutting in Kalkaji typically costs between ₹250 and ₹500 for small 1-2 inch holes, while larger 6-8 inch holes can range from ₹900 to ₹1,800 or more. Slab or wall cutting for bigger openings is usually charged per square foot, between ₹150 and ₹350, depending on thickness and access.
2. Do you provide core cutting for industrial units in Kalkaji Industrial Area?
Yes, we regularly handle larger diameter core cutting for exhaust ducting, pipeline access, and machine foundation work in industrial units, using heavy-duty cutting equipment suited for thicker concrete and higher precision needs.
3. Is core cutting noisy enough to disturb neighbours in a DDA flat?
Core cutting is generally quieter than hammer breaking, but some noise and vibration is unavoidable with concrete and RCC cutting. We use stabilised, low-vibration techniques on shared walls to minimise disturbance to adjoining flats.
4. How long does a core cutting job usually take?
A single hole between 2 to 6 inches typically takes 20 to 45 minutes. Larger industrial jobs, multiple holes, or slab cutting can take 2 to 4 hours or more depending on material thickness and access.
5. Will core cutting weaken the structure of my building?
No, when done correctly. Core cutting is far less damaging than hammer breaking because it creates a clean, controlled hole. We also avoid cutting load-bearing walls, columns, or beams without checking the structural impact first.
6. Can core cutting be done in an occupied shop without closing for the full day?
Yes, most single or double-hole jobs near Kalkaji Mandir market can usually be completed within a couple of hours, and we can schedule work during early morning or low-footfall hours if preferred.
7. What size hole is needed for a split AC pipe?
Split AC pipe holes are generally cut between 2 to 3 inches in diameter, though the exact size depends on the specific AC unit's pipe and drainage requirements.
