In the competitive world of equipment leasing, rental companies that provide cost-effective solutions for a broad range of applications, answer frequently asked equipment questions, and provide one-stop convenience will enjoy a sharper competitive edge. Since certain projects can be completed using a variety of methods, rental centers that offer a wide selection of cutting, grinding, drilling and coring equipment as well as diamond blades, cup wheels, core bits and abrasives will earn rave reviews from customers and are in a better position to obtain impressive returns on their equipment investment.
On any typical day, rental centers receive requests for dozens of different applications that require the right combination of equipment and accessories. Whether it's a contractor looking for a flat saw or a core drill to remove existing concrete or a residential contractor who wants to drill into an existing stucco structure for a remodeling project, every customer is looking for solutions that address the specific application of their particular project.
With any project, the best method to match jobsite demands with appropriate diamond blade and abrasive solutions begins with answers to a few relevant questions:
- Does the application require cutting, coring or grinding?
- What type of equipment will be used?
- Are wet or dry consumables (blades, bits or cup wheels) needed for the application?
- What is the base material?
- What size blade, bit or cup wheel is required?
The first step in the selection process is determining whether the application requires drilling a hole, grinding concrete, or cutting through base material. Once this has been decided, it is necessary to review the type of equipment to be used. If the application requires cutting, there are several types of saws that can be used such as circular, hand-held, masonry or walk behind; for coring there are different styles of core rigs available that produce anchor as well as through holes; and for grinding there are many styles and sizes of grinders from which to choose.
In order to choose the equipment, it is necessary to establish whether the application calls for wet or dry cutting, coring or grinding.
Because exposure to concrete dust can be discomforting, many contractors prefer wet applications to help reduce the amount of airborne particles. When the project requires heavy-duty wet cutting, it is recommended to use a blade specially designed for this purpose in order to increase the speed and life of the blade, which also helps increase productivity.
Equipment with built-in exhaust ventilation systems to remove dust during coring, cutting, grinding and drilling can be used for dry application use. These dust removal systems not only help provide a better work environment, they allow for cleaner cutting and coring in areas such as hospitals, food establishments or computer rooms. If the rental customer has a small project or wants to have a quick set-up time, dry may be the way to go. If water is absent, dry may be the only way to go. In most cases, the equipment being used ranges from a hand-held gas saw or circular saw to an angle grinder or dry core rigs.
Many manufacturers have blades that can be used either wet or dry for contractors working in areas that may require both wet and dry applications. These blades are manufactured for a variety of equipment including hand-held gas saws and masonry saws.
Whether cutting, coring, or grinding base materials such as reinforced concrete, brick, block, masonry, granite and tile need to be taken into consideration.
Although it may seem time consuming and intrusive, the answers to these questions will help select the most appropriate blade, core or abrasive products for cutting, grinding or coring.
Safety and security
After the basics of the job are addressed, two additional factors must be considered when selecting diamond blades and abrasive products: safety and security. For the operator and anyone near the worksite, matching the appropriate diamond blades and abrasive products with the equipment being used will help ensure safe operation. Proper maintenance and anchoring the rig securely in place is necessary to core a hole properly.
Once again, a few quick questions help navigate the process:
Does the equipment RPM match the RPM rating of the blade? To help ensure safe operation, the RPM of the equipment should not exceed the maximum RPM rating of the blade. This will help prevent blades from possibly breaking and segments flying into the surrounding area.
Do the blades arbor size and drive pinhole match the equipment design and specifications? Different blades feature distinct arbor sizes and drive pinhole configurations. Optimum performance requires an exact match for these two specifications to obtain proper fit and safe operation.
Are the blades appropriate for the style and size of safety guard attachment? The blade diameter must fit within the guard area, and the guard must be specifically designed for the type of blade, to deliver safe, proper performance.
Is the equipment properly serviced between rentals? There is no margin for error with this part of the process. Manufacturers provide detailed maintenance procedures that must be performed as recommended to keep saws, grinders, drills and other equipment working at peak levels. In turn, proper maintenance also helps the tools deliver safe and trouble-free results on every jobsite.
To accommodate the ever-changing demands of the competitive equipment marketplace, manufacturers are constantly introducing or reengineering their product offerings. Everyone wants to be the first to offer better, faster, stronger tools and accessories that help save time and money without sacrificing jobsite productivity or performance.
For rental companies, this means staying updated on the most recent developments, trends and topics related to diamond blades and abrasives. Keeping current with the latest information is essential, and there are numerous opportunities to incorporate manufacturers' news into your regular schedule of responsibilities. Read leading rental industry publications for announcements, articles and product reviews. Visit manufacturers' Web sites on a regular basis for updates on new blades and abrasive products as well as equipment, tools and related accessories. When customer requests are challenging to fulfill or unexpected questions arise, take advantage of the toll-free information services offered by most leading manufacturers.
In fact, manufacturers and rental centers are ideal partners to assist contractors and renovation professionals in finding safe, convenient and productive solutions for their equipment and accessory needs. When it comes to a temporary addition to their toolbox or workbench, most people will turn to a rental center. Because most contractors look for cost-effectiveness and convenience, rental centers that provide a wide array of equipment, diamond blades and abrasive products, along with problem-solving assistance and one-stop convenience, will continue to enjoy a sharper competitive edge.
