1/4″ SDS-Plus Penetrator Drill Bits – Multiple Lengths

Use the drop-down menu above to select length.

Take on reinforced concrete, steel decking, and embedded rebar without interruption. The 1/4″ SDS-Plus Penetrator is engineered for fast, precise drilling where smaller holes still need to cut through tough materials. A quad-carbide tipped head with flank side reinforcements and laser-welded micro-grain carbide ensures maximum strength and long tool life.

The optimized high-helix spiral flute design clears dust efficiently, while the sub-trac channel prevents blowback that can stall or bind standard bits. A multi-cutter head geometry reduces vibration, hand-arm stress, and drilling noise—keeping you in control even during extended use.

Whether you’re setting anchors, running seismic fasteners, or cutting through stone and masonry, this bit is built for professionals who demand reliable performance on every hole.

Use with SDS-Plus rotary hammers in hammer-drill mode. When crossing into rebar or steel, apply steady, firm pressure for best results.

Made in Germany – industrial-grade SDS-Plus drilling technology.
