Core Drilling Machines

Find the right core drilling machine for your next project
By Patricia Flinsch-Rodriguez, Freelance writer Self-Employed Concrete core drilling machines are primarily used in the construction industry for drilling holes in concrete, brick, block, stone as well as floors, walls and ceilings. There are many lightweight models to choose from and some can be used for wet and dry drilling.

Concrete core drilling machines are not inexpensive, and if you buy one you will also need some accessories to make the drilling go smoothly. Below is a list of accessories you may want to consider purchasing with your core drilling machine:

1. Drill stand to help with drilling accuracy and safety.

2. Heavy-duty 4 or 5 gallon metal water tank to reach maximum efficiency when wet drilling.

3. Strap wrench to remove bits from drill spindle without damaging the drill bit.

Decide between hand-held or rig-mounted core drilling machines

Hand-held core drilling machines are less expensive and are handy when you need to get into tight spaces. Rig-mounted machines are needed when you have heavy duty drilling projects that cannot be completed with a hand-held machine. The rig-mounted machines can dig deeper than the hand-held machines.
Try:  You can buy both the hand-held and rig-mounted core drilling machines from CS Unitec, Inc. Heavy-duty concrete drilling equipment and accessories can be purchased from Contractors Direct. They offer free shipping on many items shipped within the Continental United States. Check out KOR-IT, Inc. for trailer-mounted and truck hitched heavy-duty core drilling machines.

Rent your concrete core drilling machines

If you normally do not need to use a concrete coring machine on a regular basis, it may make more fiscal sense to rent your concrete drilling equipment on the occasion that you require it. Don't turn down a job just because you don't have a concrete coring machine. Renting core drill machines is a great way to try before you buy too.
Try:  Maintenance on concrete core drill machines can be expensive, so renting will save you money in the long run. Sunbelt Rentals and Rig Source Inc. have a variety of hand held and big rig concrete drilling machines available for rent. Ram Tool & Supply Inc. rents some of the larger core drill machines.

Consider purchasing a gas powered core drill

Even if you are set on buying an electric core drill machine, you should consider purchasing a gas powered core drill in addition to the electric one. There may be places that you need to drill where electricity is not available, and having a portable gasoline engine driven coring drill for those times will be a very important.
Try:  Buy a portable gas concrete core drilling machine with built-in wheels that makes it easy to move from Durham Geo Slope Indicator. Cessco Inc. sells a lightweight portable core drilling machine.

• Trailer-hitched concrete core drilling machines make set-up and clean-up on job sites very easy. Having a trailer-hitched drilling rig can save you hours of labor.
