Core cutting starts from ₹200. Indicative pricing. Final quotation depends on hole diameter, depth, material, reinforcement, quantity, access, location, and equipment requirements.
Ideal for builders, contractors, or homeowners needing 2 to 3+ core holes (for AC copper pipes, water conduits, plumbing drainage) at a nearby Kanpur location with standard access.
Indicative rate for a single standalone hole (such as one split AC hole). Covers equipment mobilization, anchor bolt setup, wet slurry containment, and travel to your locality.
For kitchen chimneys and exhaust fans. Multiple holes or standard brick starts around ₹800. Single holes in heavy RCC beams/slabs, greater wall depth, or longer travel distances typically range from ₹1,000 to ₹1,500 (higher for deep or heavily reinforced concrete).
| Core Diameter | Typical Application | Indicative Starting Range | Pricing Notes |
|---|---|---|---|
| 2 to 3 Inch (50 - 75mm) | Split AC pipes, RO water lines, electrical conduits | Starts from ₹500 (multiple) | ₹700 - ₹800 (single) | Depends on brick vs RCC and total quantity |
| 4 to 5 Inch (100 - 125mm) | Toilet soil pipes, drainage stacks, utility sleeves | Starts from ₹600 (multiple) | ₹800 - ₹900 (single) | Rebar density & slab thickness affect time |
| 6 to 7 Inch (150 - 175mm) | Kitchen chimney duct, commercial exhaust vents | Starts from ₹800 (brick/multiple) | ₹1,000 - ₹1,500 (RCC/single) | Heavy core drill rig required; downward tilt included |
| 8 to 12 Inch+ | HVAC ducting, fire risers, road test cores | Subject to site inspection & scope | Custom quotation based on depth and access |
| RCC Slab / Wall Cutting | Door openings (3x7 ft), stair/lift cutouts | Per running foot / square foot | Calculated by slab depth (4"–12") & rebar reinforcement |
Setting up a diamond core drill rig involves transporting heavy machinery, mounting the column, anchoring to the concrete with high-tensile anchor bolts, connecting the water coolant system, and preparing slurry vacuums. Whether we drill one hole or ten holes, the mobilization and setup effort is virtually the same.
Therefore, when contractors, builders, or homeowners bundle multiple penetrations (such as AC holes + plumbing cores + chimney exhaust) into a single site visit, we can pass significant savings on to you.

Helpful info: Hole size & count | Brick or RCC | Location in Kanpur | Photo/video if available
₹200 is our entry-level baseline rate for specialized shallow cuts, high-volume project batches, or minor utility openings under ideal site conditions. Actual cost depends on hole diameter, depth, material hardness, and total scope.
Because transporting professional stand-mounted rigs, anchors, and slurry management equipment requires dedicated mobilization, a single 2 to 5 inch core hole typically costs around ₹700 to ₹800 depending on your Kanpur locality and concrete type.
A 7-inch core bit has a significantly larger surface area, requiring higher-torque machinery, slower rotational grinding speeds, more diamond segment wear, and greater water flow to manage concrete slurry cleanly.
Standard reinforcement in residential slabs is accounted for in our normal RCC estimates. However, if a structural beam has extremely dense 16mm to 20mm TMT rebars or requires deep structural sectioning, the quote is adjusted based on inspection.
