Complete guide to choosing your concrete drill bits

SDS-Plus or SDS-Max: which system to choose?

SDS-Plus fits compact rotary hammers, for small and medium hole diameters. SDS-Max fits larger models, for large-diameter bits and deep drilling. Check your tool's shank type before buying.

The two systems are not compatible with each other. An SDS-Plus bit does not fit in an SDS-Max chuck. Diablo offers both formats, and Milwaukee offers SDS-Plus bits, for example in 1/2 in x 6 in.

Which length and diameter for the job?

A 6 in bit suits anchors and fasteners in a slab. Bits from 13 in to 21 in go through walls and foundations. Lengths from 31 in to 36 in are for very deep holes.

The diameter depends on the anchor to install. Plan for a hole slightly wider than the screw or plug. The anchor manufacturer specifies the exact diameter, which must be respected for a secure hold.

Drilling reinforced concrete: rebar bits

A rebar stops an ordinary bit. Diablo SDS-Plus rebar bits, in 1-1/4 in and 1-1/2 in, are designed to go through steel embedded in concrete. They fit an SDS-Plus rotary hammer.

Use a suitable rotary hammer with hammer mode on. Clear the dust from the hole while drilling. Wear safety glasses and a mask: concrete dust is irritating to the lungs.

We answer your questions about concrete drill bits

What is the difference between SDS-Plus and SDS-Max?

SDS-Plus is used with compact rotary hammers, for small and medium hole diameters. SDS-Max fits larger models, for big bits and deep drilling. The two systems are not compatible, so check your tool's shank type.

Can I use a concrete drill bit in a regular drill?

For small diameters, a hammer drill with a standard masonry bit may be enough. SDS bits require an SDS rotary hammer. See our drills and screwdrivers.

How do I drill through rebar in concrete?

Use a bit designed for rebar, such as the Diablo SDS-Plus models in 1-1/4 in and 1-1/2 in. Work with a suitable rotary hammer and drill without forcing. A standard concrete bit is damaged on contact with steel.

Which concrete drill bit length should I choose?

For anchors and fasteners, a 6 in bit is often enough. To go through a wall or a foundation, look at 13 in to 21 in. Lengths of 31 in to 36 in are for very deep holes. Choose the diameter based on the anchor.

How do I maintain my concrete drill bits?

Clean the bit after each use and remove dust from the flutes. Lightly grease the SDS shank and store the bit dry. Replace a bit with a worn tip. To drill steel, see our metal drill bits.
