SDS Drill Bit Applications: Matching Bits to Concrete, Brick, Block and Stone

The material being drilled has more effect on bit choice than almost anything else. If you supply contractors across several trades, matching your range to their materials keeps returns low and repeat orders high.

Poured and precast concrete

Concrete is hard and often reinforced. Choose 4-cutter heads for rebar contact and tough carbide grades for long life. For anchoring, a tight tip tolerance matters most. Common users are electricians, steel erectors, HVAC and fire-protection installers.

CMU block

Concrete masonry units are softer and hollow. Fast 2-cutter heads work well, and holes need to stay clean to avoid blowing out the web of the block. A centering point helps on the rough face.

Clay brick

Brick is abrasive and can spall around the hole. A sharp 2-cutter head and steady feed give a clean entry. Restoration contractors often ask for smaller diameters and longer lengths for tie and anchor work.

Natural stone and granite

Hard, dense stone wears carbide quickly. Use larger carbide inserts and good dust clearance, and run the bit at a controlled feed so the head does not overheat.

Tile and porcelain

Tile and porcelain are hard and brittle. Cross-tip or dedicated tile bits drill with less chipping. Some tile bits are used without hammer action to protect the glaze, so check how the bit will be used.

Through-walls and slabs

Long bits of 12–36 in need straight bodies and efficient flutes. Four-flute designs and tight straightness tolerances reduce binding on deep holes.

Turning this into a product range

Group your SKUs by application, such as Anchoring, Masonry, Through-Wall and Tile, rather than by size alone. Contractors find the right bit faster, and your packaging and catalog become easier to use. We can build application-specific packaging and labeling to your artwork.
