How big is a 2x4 stud?
A common 2 x 4 stud actually measures 3 ½ inches by 1 ¾ inches and it is recommended to leave 5/8ths of an inch on both sides of the hole so if your boring the wide side it is safe to bore a centered hole up to 2 ¼ inches in diameter and if your boring the narrow side on center that gives you ¾ of an inch in diameter.
What is the angle of a metal boring bit?
Bits for drilling metal are harder than bits used for wood they are typical made from cobalt or titanium and have a pointed tip that flares out at either a 118 degree angle which is considered a general purpose metal bit or a 135 degree angle which is a more specifically metal boring bit.

How to protect wires from nails?
The National Electrical Code requires holes containing non-metallic cable (often called Romex) or flexible metal-clad cable (the type you buy with the wires already in it) be set back 1-1/4 in. or more from the edge of a stud (Fig. A) to protect the wires from nails and screws. (The 1-1/4-in. screws and nails used to secure 1/2-in. drywall penetrate the studs about 3/4 in.) Most electricians keep their inspector happy by drilling 3/4-in. holes dead center on a 3-1/2 in. wide stud. This gives them a hole large enough to run two electrical cables and leave 1-3/8 in. of protective wood on each side. If they need to run more wires, they’ll drill more holes directly above the others. If a hole comes any closer than 1-1/4 in., your inspector will make you install a 1/16-in. thick protective metal plate (Fig. A). Available in 3-in. and longer lengths, the plates can be found at home centers and hardware stores.
What are the benefits of wood studs?
The studs provide the strength and framework for the structure, and the empty spaces between the studs serve an important function , too: They provide the perfect place—a veritable vertical freeway—to run pipes, vents, drains, wires and ductwork. The drawback? When you have to run pipes, ducts or wires horizontally through the studs, you often have to notch or drill holes—sometimes big ones—to get them to their destination. But you can't just drill and saw away. There are rules you have to follow for drilling and notching studs. Some rules help ensure the structural integrity of a wall. And others are aimed at protecting pipes and wires that could be damaged by screws, nails and other fasteners driven into a wall.
What percentage of the studs should be in a hole in a roof?
The technical yet important rules are: Holes in bearing wall studs (exterior and interior walls that bear the weight of the roof and/or other stories above) may not exceed 40 percent of the width of the stud. Notches in bearing wall studs may not exceed 25 percent of the stud’s width.
Why are angled holes so tough to pull wires through?
Angled holes are tough to pull wires through because the cable catches on the sharp edges.
How far back should a plumbing hole be?
The mechanical codes for plumbing and heating, ventilation and cooling (HVAC) systems also dictate that holes containing pipes be set back 1-1/4 in. from the edge of a stud to protect the pipes from fasteners.

What is the best way to coat electrical cables?
Professional electricians often use a lube product to coat the cable as it's being pulled through wall plates. The cable lube makes the cable slippery and reduces the likelihood of tearing the sheathing as it passes through the drilled hole. It also reduces the effort required to pull the cable.
How to fish a cable in the attic?
From the attic or basement, pull steadily on the fish tape while a helper feeds the cable into the wall opening. It may take some finessing as the tip of the fish tape blade passes through the drilled hole in the wall plate. Be gentle as you fish the cable through the hole since it is important not to tear the sheathing on the cable. It helps to pull in short, 2- to 3-foot intervals, so that the cable is being pulled at the same time your helper is feeding from the other end.
Where do you run cable in a basement?
When adding or replacing wiring in finished walls, most electricians will attempt to make the horizontal portion of the cable run in the unfinished attic, basement, or crawlspace areas, looping the cable down or up through the wall cavity, across the floor or ceiling joists, and then vertically through another stud cavity to the next wall box opening. For the horizontal portion of the cable run, this can involve drilling holes in the joists where the cable will pass.
How to make a fish tape head?
Strip about 6 inches of outer sheathing from one end of the cable, then hook the conducting wires and bare copper grounding wire through the loop at the end of the fish tape blade. Bend the wires over, and wrap several loops of electrical tape around the wires and the end of the fish tape. The goal is to have a smooth head that will easily slide through the hole in the wall plate without getting caught.
Why do you loop wires in a house?
But when you are running wire in existing construction, the looping method prevents the expensive and time-consuming process of opening up walls and patching them after the wires are run.
Where do you run NM cable?
Remember to consult your local code on requirements for running cable. For example, in exposed locations such as open basements or attics, NM cable usually needs to be run through holes or notches cut in joists rather than stapled to the face of the joists. Thus, when looping a length of NM cable between new wall boxes, the process may involve running it through holes drilled in the floor joists in order to reach the stud cavity.
Can you run raceway wire on walls?
There is a third option for wiring. It involves running surface raceway wiring (such as Wiremold products) on the surfaces of the walls, but that can look unprofessional—and it may not be allowed by the electrical code in some areas.
