When renovating a home, fitting a split air conditioner in a high-rise apartment in Whitefield, Bengaluru, or laying heavy HVAC plumbing through reinforced concrete beams in a Gurgaon commercial park, you encounter a structural challenge: drilling precise circular openings through solid RCC (Reinforced Cement Concrete).
Using traditional hammer drills or manual chisels causes structural micro-fractures, jagged wall openings, and cosmetic ruin. This makes professional diamond core drilling essential.
Homeowners and project site managers across India face a choice between two primary options: Urban Company (the popular aggregate home service app) or a specialized national contractor like Core Cutting India ([email protected]).
This detailed guide compares both options across equipment depth, technical capability, pricing structures, and project scale to help you make the right choice.

What Is Core Cutting and Why Does the Right Vendor Matter?
Core cutting uses diamond-tipped cylindrical drill bits to cut smooth, circular holes through tough construction materials—including heavy RCC, brickwork, granite, and steel-reinforced slabs. Unlike percussion drilling, diamond core drilling relies on rotary action combined with high-grade industrial diamond dust, creating clean, exact cuts without damaging surrounding structures.

URBAN COMPANY CORE CUTTING INDIA
1. Scope of Work & Capabilities
Urban Company: Convenience for Quick Standard Residential Needs
Urban Company operates on an aggregator model. Their professionals excel at standard handyman, plumbing, electrical, and appliance installations.
-
Primary Use Case: Standard 3-inch or 4-inch core cuts through soft brick walls or thin partition masonry for split AC copper piping and small kitchen exhaust pipes.
-
Limitations: Most platform partners carry portable handheld electric core drills. They are typically unsuited for heavy-duty 8-inch to 24-inch core cuts, deep slab penetrations (>12 inches deep), or thick structural RCC beams packed with heavy steel rebar.
Core Cutting India: Specialized Structural Precision
Core Cutting India operates as a dedicated heavy-duty structural modification firm.
-
Primary Use Case: Any project requiring specialized precision—from a 2-inch utility line to a massive 20-inch industrial opening through heavily reinforced concrete slabs, columns, shear walls, or bridge piers.
-
Strengths: Using rig-mounted, heavy-duty Hilti and Bosch diamond core drills, Core Cutting India handles deep horizontal, vertical, and angled drilling through high-grade concrete (M30, M40, and above) without structural vibration.
2. Equipment & Technical Execution
| Technical Feature | Urban Company Partner | Core Cutting India |
| Machinery Used | Handheld core drills / heavy hammer drills | Rig-mounted industrial diamond core drills (Hilti, Husqvarna) |
| Diameter Range | 2 inches to 4 inches (Occasionally 6 inches) | 1 inch up to 24+ inches |
| Depth Capacity | Standard wall thickness (3 to 6 inches) | Up to 1,000 mm (1 meter+) deep slabs & beams |
| Water Suppression | Basic manual spraying or dry cut | Integrated water-feed systems & slurry vacuum containment |
| Reinforced Steel Cutting | Struggles with thick TMT rebar | Cuts through high-tensile TMT steel bars cleanly |
Real-World Example: Mumbai High-Rise Apartment
A homeowner on the 18th floor of a high-rise in Worli, Mumbai needed a 6-inch exhaust hole drilled through a 9-inch load-bearing RCC shear wall for an imported kitchen hood.
An app-based technician's handheld unit seized when hitting 16mm TMT rebar inside the wall. Core Cutting India was called to complete the job. Using a vacuum-mounted anchor rig and wet diamond bit, they completed the clean 6-inch cut in 35 minutes without generating dust or cracking the exterior façade plaster.
3. Cost Comparison & Pricing Models
Understanding vendor pricing prevents unexpected costs during home or commercial projects.
Core Cutting Pricing Models in India:
Urban Company:
Fixed Service Unit Base Rate (e.g., ₹999 - ₹2,499 per hole)
+ Add-on fees if wall thickness or material exceeds defaults.
Core Cutting India:
Linear Inch / Diameter Measurement (e.g., ₹100 - ₹350 per inch depth)
OR Custom Project Estimate for multi-hole bulk execution.
Urban Company Pricing
Urban Company usually charges per item or per hole slot.
-
AC Core Cut (3-inch): Approximately ₹999 to ₹1,499.
-
Chimney Cut (4 to 6-inch): Approximately ₹1,499 to ₹2,499.
While clear for a single hole, costs accumulate quickly if you require multiple utility cuts, deep slab penetrations, or custom angled holes.
Core Cutting India Pricing
Core Cutting India typically charges based on depth, diameter, and concrete grade (e.g., ₹100 to ₹350 per inch of depth), or offers a bulk site quote. For multiple penetrations across a bungalow, villa, or commercial site, a dedicated contractor provides lower per-hole costs and transparent, scalable pricing.
4. Safety, Cleanliness & Slurry Control
Water is required during diamond drilling to lubricate the core bit and keep concrete dust out of the air. Managing this water-concrete mix (slurry) is critical when working in finished living rooms or furnished offices.
-
Urban Company: While partners attempt clean work, handheld drilling can allow dirty slurry to run down painted walls if containment bags leak.
-
Core Cutting India: Professional crews use slurry-collection rings connected to wet industrial vacuums. This collects runoff directly at the cutter head, protecting interior wall paint, marble flooring, and nearby furnishings.

Frequently Asked Questions (People Also Ask)
What is the difference between specialized core cutting and standard drill services?
Standard drills use impact hammering, which can crack plaster, weaken concrete, and fail when encountering steel rebar inside RCC. Specialized diamond core cutting uses a rotating industrial diamond bit that grinds smoothly through concrete and steel rebar without structural vibration, leaving a precise circular hole.
Can Urban Company perform RCC core cutting for 6-inch or 12-inch diameters?
Urban Company primarily handles standard residential installations (3 to 6 inches) using handheld tools. For larger diameters like 8, 10, or 12 inches through thick RCC, specialized rig-mounted equipment from dedicated contractors like Core Cutting India is required.
How much does core cutting cost per inch in India?
Core cutting in India generally ranges from ₹100 to ₹350 per inch of depth, depending on hole diameter, material hardness (brick vs. M40 grade RCC), site accessibility, and total hole quantity.
Why is diamond core cutting essential for AC and chimney installation?
Diamond core cutting creates precise, smooth openings that allow copper pipes, drain tubes, and exhaust flues to pass without sharp bends or wall damage. This reduces air leakage, prevents water seepage, and protects the structural strength of your walls.
Final Verdict & Contact Details
For simple residential jobs in soft masonry, Urban Company offers quick app booking. However, when working with reinforced concrete, large pipe diameters, or projects where structural safety and neat execution matter, hiring a dedicated contractor is the safer investment.
