What is Core Cutting?
Precision Core Cutting & Drilling for Every Need
Core cutting is a specialized concrete drilling technique using diamond-tipped cylindrical drill bits to create precise circular holes through RCC slabs, concrete walls, brick masonry and asphalt. Unlike traditional chipping or jacketing methods, diamond core drilling is vibration-free, accurate and causes minimal structural disturbance.
Devki Projects uses advanced water-cooled diamond core drilling machines to deliver clean, accurate holes of any diameter — from 25mm plumbing sleeves to 300mm+ HVAC ducts — in RCC slabs, beams, columns and walls.
Available in diameters from 25mm to 600mm for any application
Water-cooled diamond bits — dust-controlled, vibration-free drilling
Works on RCC slabs, columns, beams, brick & block walls

Applications
Where We Do Core Cutting
Core cutting is used across MEP, plumbing, HVAC, drainage and structural modification work in all building types.
Plumbing Sleeves
Precise holes through slabs and walls for water supply pipes, drainage lines and sanitation risers without damaging reinforcement.
Electrical Conduits
Clean conduit holes through walls, slabs and beams for electrical wiring, data cables, fire alarm and security system routing.
HVAC & AC Ducts
Large-diameter core holes (150–600mm) through RCC slabs and walls for air conditioning ducts, fresh air intakes and exhaust vents.
Drainage & Sewage
Drainage pipe sleeve openings in podium slabs, basement floors and terrace slabs for rainwater outlets and sewage connections.
Structural Openings
Core holes in columns and beams for post-tensioning anchor pockets, bearing plate holes and structural inspection ports.
Slab Penetrations
Multiple core holes in floor slabs for soil stack pipes, vent pipes, fire sprinkler branches and firefighting riser pipes.
Wall Openings
Wall sleeve cutting for AC pipe and drain routing, gas lines, split AC wall brackets and inter-floor communication cables.
Anchor & Bolt Holes
Precision anchor holes for chemical anchors, hold-down bolts, railing bases, signage supports and machinery mounting.
How We Work
Our Core Cutting Process
A systematic, safety-first approach to every core cutting job — from enquiry to site handover.
1
Enquiry & Scope
Share hole size, depth, quantity and location. We advise the best approach.
2
Site Inspection
Our team visits to assess slab thickness, rebar position and access requirements.
3
Marking & Setup
Precise hole centres marked. Drill rig anchored. Water supply and waste slurry containment set up.
4
Diamond Drilling
Water-cooled diamond core drill creates clean, accurate holes. No vibration, no structural damage.
5
Cleanup & Handover
Slurry removed, site cleaned. Hole edges smoothed. Work completion certificate issued.
Equipment & Drill Types
Machines & Bit Sizes We Use
We operate a full fleet of professional-grade core drilling machines to handle any job size, from small conduit holes to large duct penetrations.
25mm – 75mm Bits
Small-bore drilling for electrical conduits, anchor bolts, railing bases and gas line sleeves through walls and slabs.
80mm – 150mm Bits
Mid-range for plumbing sleeves, soil pipes, drainage lines, sprinkler risers and split AC pipe routing.
150mm – 300mm Bits
Large-bore for HVAC supply ducts, fresh air intakes, exhaust shafts and MEP bundles through thick RCC slabs.
300mm – 600mm Bits
Extra-large industrial cutting for service shafts, sump connections, pump openings and large MEP duct penetrations.
Rig-Mounted Drill
Floor-anchored electric rigs for vertical slab drilling — guarantees perfectly plumb holes with controlled depth.
Wall-Mounted Drill
Side-anchored machines for horizontal wall drilling — ideal for sleeves through beams, shear walls and RCC columns.
Water Cooling System
Continuous water flow cools the diamond bit and suppresses dust — wet-cut method ensures clean, precise holes.
Slurry Vacuum System
Industrial wet vacuum collects drilling slurry immediately — work area stays clean with zero mess on lower floors.

FAQs
Frequently Asked Questions
Common questions about core cutting and drilling services in Mumbai.
What is core cutting and why is it used?
Core cutting is a method of drilling precise circular holes through concrete, RCC slabs and walls using diamond-tipped cylindrical drill bits. It is used to create openings for plumbing pipes, electrical conduits, HVAC ducts, drainage lines and anchor bolts without causing structural cracks or vibration damage to the surrounding concrete.
What diameters can you cut?
Devki Projects can cut holes from 25mm (1 inch) for small anchor bolts up to 600mm (24 inches) for large HVAC ducts and service shafts. We carry a full range of diamond core bits to handle any diameter requirement on-site.
Is core cutting safe for occupied buildings?
Yes. Diamond core cutting is vibration-free and uses water cooling to eliminate dust. The wet-cut method contains slurry locally with vacuum systems. There is no impact to neighbouring units, no structural cracking from vibration, and minimal noise — making it ideal for occupied residential buildings and commercial spaces.
How long does core cutting take per hole?
Time depends on hole diameter, depth and concrete hardness. A standard 100mm hole through a 150mm RCC slab typically takes 15–25 minutes. Larger diameters (300mm+) in thick slabs may take 45–90 minutes per hole. We always give a time estimate before starting work.
Can you cut through reinforced concrete with rebar?
Yes, our diamond core bits are designed to cut through both concrete and embedded steel reinforcement. However, for structural elements like beams and columns, we always recommend a structural engineer's assessment before cutting to ensure the structural integrity of the element is maintained.
Do you serve areas outside Mumbai?
Our core cutting team primarily serves Mumbai, Thane, Navi Mumbai and the extended Mumbai Metropolitan Region (MMR). For large-volume projects, we can mobilize to other Maharashtra locations — please call us to discuss your specific project location and requirements.
