Professional types of concrete sawing and drilling are prevalent in countries like USA, Japan, Australia and Europe. In India, it really is still a young but growing industry. Because of a heightened spending on infrastructure projects and residential & commercial construction, India holds tremendous potential in terms of diamond tools and concrete sawing and drilling.

Another critical factor inducing the adoption of such sophisticated methods may be the constantly rising labour costs. Within the last decade, concrete and construction industry has experienced sharp increases in labor rates and overhead expenses. Due to the high labor and overhead costs associated with most sawing and cut to length machine, the rate in which the job is completed has grown to be vital. Using outdated cutting &drilling techniques and drilling equipment that heavily relies upon guessing and operator testing only bring about waste of time and money. Today, in order to remain competitive, the contractors are under pressure to embrace more sophisticated types of concrete sawing & drilling.

“The industry for floor saws, wall saws and powered drilling machines happen to be in a nascent stage today but growing at about 40% per annum as the fee for labor rises, using machines to quicken work and increase productivity and excellence of work boosts phenomenally. Presently about 600 machines Floor Saws, Wall Saws and Powered Drilling Machines are in operation. Low Powered Hand Held Drilling and sawing are in many thousands and it is very difficult to give even an approximate number.” - M.Venkatesh, Executive Director, Diabu Diamond Tools

Professional diamond concrete cutting systems can offer significant advantages over conventional concrete removal methods. Such as reduced downtime, precision cutting, upkeep of structural integrity, reduced noise, dust and debris, limited-access cutting, and the ability to cut heavily-reinforced concrete.

There are very few organized players within the core cutting arena. Most of them are extensions of worldwide manufacturers for example Hilti, TYROLIT, Husqvarna and Diabu. Like in some other industry, the current market is flooded with Chinese equipment and fly by night traders who sell inexpensive, poor machines from China with the objective of making quick money. These machines, however, do not have post sales support nor would be the machines suited and made to operate in the Indian environment. Mr. Akhil Jain, authorized and exclusive distributor of Husqvarna’s power tools in India says, “Users with low budget prefer to consider low quality Chinese makes but only find yourself spending more on repairs.”

With respect to manufacturing facilities in India, approximately 25% are manufactured indigenously, the rest imported and the bulk originating from China. Hilti which acquired Bhukhanvala Diamond Systems during 2010 is applying it as a its manufacturing facility to increase develop and expand the development facility for diamond tools and disks as well as to strengthen its position in the Indian diamond consumables market.

“HILTI was the pioneer in introducing diamond coring technology in India. Over the past 5-10 years, the technologies have matured to some stage where even on residential sites, coring is the preferred technology for fast, vibration-free penetrations. Right now we see the market for coring at greater than 50 crores.” Shyam Raghunandan, Head Marketing, Hilti India

Manval Goel, Business Head - Construction at TYROLIT India Superabrasives Tools believes the industry measurements of controlled concrete dismantling in India is in close proximity to INR 120 crores. This consists of branded and unbranded market too. TYROLIT has a variety of core cutting electric, hydraulic and petrol driven machines. TYROLIT’s machines are capable of doing drilling as much as 1000 mm diameters. Its Ultimate Drilling Machine (UDM) is a self-propelled gasoline driven EI core cutting machine highly appropriate for drilling at runways. TYROLIT has 27 Global Production Units as well as its core cutting machines and drills are manufactured in Switzerland, Austria, United statesA. and also other parts of the world. These machines have a manufacturing warranty of one year. Also these are generally quite sturdy machines and require suprisingly low mainte-nance. TYROLIT’s Unique Service Concept provides a few of the service requirement at site to care for emergency Breakdowns.

Diabu Machines has entered the Indian market. Designed remembering the Indian working conditions and the Indian operator, Diabu’s floor saws, wall saws and drilling machines are made on the platform of robust, rigid and high productivity. Diabu uses top quality and right configuration steel, longevity and maintenance free bearings, dust and water protected motors, bearings and sliding and rotating parts. Most if not all fasteners are manufactured from either stainless-steel or rust proof and tensile steel. Aside from being simple to use, maintenance is also very easy with simple to access grease and oil points.

“There can be a significant necessity for education about controlled dismantling as a technology inside the construction industry. Other challenges connect with acceptability and adaptability of the technology in a few of the major projects, drilling and sawing vis-à-vis the traditional chisel and hammer, economics related to the technology since this is expensive, application with illiterate labor and localized accessibility of the technology.”

Selecting the right blade (for that saw, the content as well as the job) is the most important consider getting maximum performance. All kinds of other variables also affect blade performance. Changing any variable will have an effect on cutting speed and blade life.

Concrete cutting as an application oriented process, blades are supplied as per end application requirement and job site requirements. The key concrete cutting tools that happen to be utilized are the wall (or track) saw, the flat (or slab) saw, the core drill, as well as the wire saw. Wall sawing is typically specified to reduce precise dimensional door, vent and window openings. Straight along with bevel cuts are possible with all the wall saw. The wall saw is likewise a great choice for creating precise openings in virtually any concrete structure. Flat sawing is typically accustomed to cut horizontal flat surfaces for example floors, bridge decks, and pavement. Flat saws are usually used to provide expansion joints, remove damaged pavement sections, neat and repair random cracks dexqpky76 repair, and remove concrete sections for demolition purposes. Core drilling techniques are being used when precise, circular cuts are important for example openings for plumbing, electrical and HVAC installations, creating holes for routing cables or placing anchoring bolts, installing load carrying devices or dowel bars, or concrete sample analysis. Wire sawing can be used for removing of thick sections of concrete. It is perfect for removing large sections of heavily reinforced concrete, including piers, towers and bridge sections, and cutting concrete in areas where work space is restricted.

Most of the decision of cutting wet or dry is dependent upon ones preferences and job requirements. While many sawing or drilling is wet, conditions such as water scarcity in sites, requirement to hold the site clean water/slurry as a result of proximity with existing office/ factory /commercial/residential space, proximity to electrical or some other such dangerous areas may warrant dry cutting. However, cautions Mr.Venkatesh of Diabu, “If the cutting is dry it is always preferable to use saws which can be laser welded or atleast have special reinforced brazing. Using such blades be sure that the extremely high heat generated during dry cutting does not damage the blade which may also cause injury and cause accidents.”

Apart from the kind of cutting and dry or wet cutting, forms of concrete also influence your choice in choosing a blade. The length of curing time after concrete is poured greatly affects the way a diamond blade will connect with it during cutting. Curing could be impacted by weather (temperature, moisture and time of year) and also the composition (admixtures, aggregate and sand). Cured concrete is usually set a minimum of 2 days. The sand is utterly bonded with the mortar along with the concrete reaches full hardness. Concrete is generally in its green state for 6 to 2 days after it really is poured. With this early state, the sand is not really completely bonded together with the mortar as well as the concrete doesn’t reach full hardness. When cutting green concrete, the sand loosens more readily, and flows more freely inside the slurry, and produces a lot more abrasion on the diamond blade. Undercut protection is essential when cutting green concrete to avoid excessive wear about the steel core in the segment weld. Green concrete sawing is typical when working on new construction projects for example; motorways, runways, driveways & industrial flooring.

The size and type of aggregate possess a great impact on the general hardness of concrete and also the blade to decide on. The aggregate can certainly make up up to 75% from the total volume. On the whole, larger aggregate will create the concrete act harder, slowing drilling process. Smaller aggregates make a blade cut faster. Sand is part of the aggregate mix, and determines the abrasiveness of concrete. “Small aggregate” is often sand. Sand can either be sharp (abrasive) or round (non-abrasive). To look for the sharpness of sand, you must know where the sand comes from. Crushed sand and bank sand are usually sharp; river sand is normally round.

Choice for core drilling operation will likely requires learning the diameter in the final hole required, surface finish of the drilled hole, surface and accessibility from the drilling area.

“Tool horsepower, tool reliability and simplicity may also be necessary for selecting the right tool”, adds Mr. Shyam Raghunandan of Hilti, India.

Manav Goel, of TYROLIT summarizes, “Overall, factors like diameter of your core, entire core, power and speed of motor, percentage reinforcement, grade of concrete, horizontal or vertical drilling, Silicon steel core cutting machine, anchor or vacuum fixation assistance in deciding which concrete core cutter for the project.”

Conventional concrete cutting and drilling methods generated considerable amounts of dust. While wet cutting or drilling operation is not going to generate dust as it uses water, the instance of dust is nearly totally avoided. However, the slurry generated should be cleaned regularly. For dry cutting, most manufacturers have dust extraction systems as accessories.

Besides saw speed, the ease of transport and installation is important in jobsites which have single doors or window openings to become remove or where the saw must be constantly moved in one floor to the next. Some machines work in a modular system thus bringing in certain advantages, as the single component might be easier transported and installed.

With respect to costs, these machines are not so expensive machines of course, if regularly maintained, the price of maintenance can be kept only any machine a yearly spend of about 6% - 10% of the cost of the equipment.

The popularity is clearly lighter, lesser, faster plus more profitable. But what includes this development is a stronger demand that operators be trained effectively. Also, contractors ought to be made aware or there must be experts who can suggest the very best techniques and equipment for the most efficient and expense-effective cutting at any stage of the project.
