Drill Bits (Concrete)

Concrete drill bits use a hardened carbide tip to bore into concrete, brick, block, and stone. Designed for hammer drills and rotary hammers, their tip survives the pounding and abrasion of masonry. Matching the bit to your drill's chuck and using the correct diameter for anchors is essential. We stock carbide masonry bits in round-shank and SDS styles.

Shank Types — Match Your Drill

Round/hex shank: for standard drills and hammer drills with a three-jaw chuck. SDS-plus: a splined shank for rotary hammers up to ~1" — the common professional standard. SDS-max: larger splined shank for big rotary hammers and heavy drilling. Using the right shank for your tool is the first selection step — they're not interchangeable.

How They Cut

The carbide tip chips and pulverizes masonry as the hammer action pounds and the flutes clear dust. Hammer or rotary-hammer mode is essential — drilling concrete in rotation-only mode (like a standard bit) barely cuts and burns the tip. The bit's diameter must match the anchor it's drilling for.

Anchor Hole Accuracy

For wedge, sleeve, and concrete-screw anchors, the exact bit diameter matters — anchors are rated to a specific hole size. Carbide bits are sized to ANSI standards so the hole matches the anchor. Using a worn or wrong-size bit undersizes or oversizes the hole and reduces anchor holding power.

Selecting the Right Concrete Bit

Match the shank to your drill (round for hammer drills, SDS-plus/max for rotary hammers), and the diameter to the anchor or hole you need. Use hammer mode, clear dust from deep holes, and replace dull bits — a worn carbide tip drills slow and oversizes holes. For rebar, use a multi-material or rebar-cutting bit.
