The correct drill bit size for a 3/8″ wedge anchor is 3/8″.
How much deeper than the anchor being installed should the hole be drilled?
How to drill hole: When drilling a hole into concrete, brick or block base material, the hole must be drilled 1/2″ deeper than the concrete anchor will penetrate. Why: The extra depth of the hole will ensure that the anchor does not bottom out and will allow space for dust from the drilling process.
How deep should anchor bolts be in concrete?
Steps to Installing Concrete Fasteners The hole should be drilled 1/4″ to 1/2″ deeper into the base material than the anchor will penetrate. This allows for any material to fall when the anchor is inserted into the hole. After the hole is drilled, it must be cleaned of all debris, material or dust.

What size drill bit do I need for a 1/4 concrete anchor?
The 1/4” diameter requires the use of a 3/16” carbide tipped bit.
What size drill bit do I need for a 5’8 drop in anchor?
Installing a 5/8″ Drop-In Anchor Zinc Plated Drill a 7/8″ hole into the concrete using a carbide-tipped bit that meets ANSI Standards B212. 15. The depth of the hole can be deeper or equal to the minimum embedment depth of 2-1/2″ which is equal to the length of the anchor .
What size drill bit do I need for anchors?
“You want a drill bit that’s big enough to drill a hole in the wall, and easy to push the anchor in with your thumb,” Donahue explains. “You don’t want to have to force it in there. The drill bit should be the same size as the body of the anchor you’re using.”Mar 18, 2021.
What can I use instead of a 3/8 drill bit?
If it’s UNF 3/8 24TPI, you need 1/24″ smaller drill, which means a 0.3333″. 21/64″ would be slightly under, 11/32″ slightly over. A letter R drill would probably be “perfect”, a letter Q drill is about a thou under.
What size drill bit do you use for a 3/8 drop in anchor?
Installing a 3/8″ Drop-In Anchor Zinc Plated Drill a 1/2″ hole into the concrete using a carbide-tipped bit that meets ANSI Standards B212. 15. The depth of the hole can be deeper or equal to the minimum embedment depth of 1-9/16″ which is equal to the length of the anchor .
Why can’t I drill through concrete?
Drilling into concrete is difficult because concrete is dense, is hard, and has embedded aggregate stones that can be obstacles to the drill bit. Drilling can quickly dull drill bits. When the bit encounters aggregate, the bit drags even more.
What kind of drill bit do I use for concrete?
Drill bits that can drill through concrete are called masonry bits. They are also good for drilling through brick and stone. Drill bits with a tungsten carbide tip are the strongest; when it comes to solid concrete, the sharper the better. Masonry bits cut holes through concrete in two steps.
What is the strongest concrete anchor?
Wedge Anchors are extremely popular and are one of the strongest anchors for hold strength. Wedge anchors look and function like a sleeve anchor but have a much smaller sleeve near the bottom of the anchor.
What is masonry screw?
Concrete screws or masonry screws as they’re also commonly known as, are specially designed to fix materials to masonry surfaces such as concrete or brick. They feature a full thread from head to tip, which is deeper than a normal screw thread to ensure a high pull out resistance.
