Can you drill into reinforced concrete?
Drilling into Reinforced Concrete
‘ It is best to keep the drilling depth 1-2 cm shallower than the wall’s thickness to prevent spalling (splintering or chipping) on the inner wall. Due to the density of ferro-concrete, a hammer drill is usually needed – for which we provide high quality drill bits.
How do you drill through concrete rebar?
Quote from the video:

How powerful a drill do I need?
Typically ranging from 450 watts for basic models to around 1500 watts for the more powerful hammer drills. A higher wattage is better for drilling masonry. While if drilling into plasterboard, a lower wattage will suffice. For most basic home DIY jobs, a 550 watt drill is adequate.
Do I really need a hammer drill for concrete?
The most common type of drill bit that you use when drilling into concrete is masonry drill bits. This is true whether you are using a regular drill or a hammer drill. It would be best if you used a masonry drill bit made of tungsten carbide. That way, it is strong enough for concrete drilling.
What size hole do you drill for 5/8 rebar?
3/4-inch
1. For installations with 5/8-inch threaded rod and #5 rebar size, the preferred ANsI drill bit diameter is 3/4-inch.
Can you drill rebar into the ground?
Assuming you are talking about small-diamter bar, which seems likely as you are concerned about bending it, I would suggest a long (12-18″ or so) drill bit and drilling a hole in the ground to get the rebar started straight, before finishing with a hammer.

What is a SDS drill?
SDS drills, also known as chisel or hammer drills, are a powerful type of hammer tool best suited to heavy-duty drilling applications. These specialist power tools can be used to drill through materials such as steel, brick, masonry, and concrete, making them handy tools for a range of tasks.
What is SDS drill bit?
SDS drill bits are specifically designed to drill into tough surfaces such as brick and concrete. SDS stands for slotted drive system and refers to the unique design of the drill bit shaft. The shaft features grooves that snap into the chuck and allow it to move up and down in a hammer action.
What is the difference between SDS and SDS Plus drill bits?
Physically there are size differences in the masonry bits. SDS Plus have a 10mm shank, while the SDS Max has an 18mm. This means that SDS Max bits have an increased capability for tougher masonry work, withstanding more torque and force.
What is the difference between a SDS drill and a hammer drill?
SDS Rotary Hammers are similar to Hammer Drills in that they also pound the drill bit in and out while it’s spinning. They use a piston mechanism instead of a special clutch enabling them to deliver a much more powerful hammer blow than traditional Hammer Drills – they are able to drill larger holes much faster.
Why are SDS drills better?
An SDS drill is a powerful, versatile, and capable drill. They are more efficient than standard rotary drills and hammer drills. SDS drills can drill through concrete, brickwork, steel and other tough materials. They combine the rotary motion of a standard drill with a hammering action.
Is it worth getting an SDS drill?
As for do you need an SDS, I would say they are very handy things to have. For putting curtain rails up (drilling into lintels), removing tiles and plaster with the hammer action, drilling deep holes right through walls and for drilling into solid concrete (to fit ground anchors) mine has been a great investment.
Can I use SDS-Plus in normal drill?
If you use them in a normal drill and they work loose, and the shank that’s gripped in the chuck, gets chewed up a bit, they may not fit in a SDS chuck. I wouldn’t use them until you have an SDS drill.
