2-Schneiden SDS-PLUS Hartmetall-Hammerbohrer-Set (5-teilig)

I was a bit skeptical about the carbide tip holding up, but after drilling into old concrete with rebar, these bits are still sharp and haven't chipped. The two-cutter design really makes a difference in speed.

These 2-cutter bits cut through my concrete foundation way faster than my old standard masonry bits. The carbide tip hasn’t chipped at all after drilling a dozen holes.

Drilled about 20 holes into reinforced concrete for shelf anchors and the multi-faceted carbide insert still looks brand new. The 2-cutter design really clears dust fast, so I'm not fighting to pull the bit out between holes.

The carbide tips held up great when I accidentally hit a nail in the wall—no chipping at all. Really glad I grabbed these on clearance, as they’ve handled everything from brick to concrete so far.

These cut through rebar like butter compared to the standard bits I've been using. The multi-faceted carbide tip seems to hold up well even after drilling into old concrete.

First time using 2-cutter bits and the difference in speed through reinforced concrete is noticeable. The multi-faceted carbide tip held up well against rebar on my second hole, no chipping at all.

These bits cut through concrete block like butter, and the carbide tip hasn't chipped after a dozen holes. The 2-cutter design really does reduce binding, making the work go faster than I expected.

Switched from a standard masonry bit to this set and the difference is night and day — the multi-faceted carbide inserts really do grip the rebar instead of skipping. Drives effortlessly through a cinder block wall without chipping.

Punched through three concrete slabs without losing its edge — the multi-faceted carbide insert really holds up. Each bit fits snugly in my rotary hammer.

Bought these bits to drill into some old concrete and they went through like butter. The multi-faceted carbide tip felt solid and didn't chip at all.
