Husqvarna 594101504 4 Inch Diamond Core Drill Bit 24 Inch Tube Length B10 Vari-Drill Reinforced Concrete Masonry Extended Reach Wet Cutting

Drill Deep 4-Inch Holes in Hard Concrete with the Husqvarna Extended Reach Core Bit

Achieve professional results in deep structural applications with the Husqvarna 594101504 4-Inch Diamond Core Drill Bit. As part of the B10 Vari-Drill series (Silver performance level), this bit is engineered to solve the common problem of limited drilling depth. With an impressive 24-inch tube length, it allows you to penetrate thick foundations, bridge decks, and heavy masonry walls in a continuous run, eliminating the instability and time loss associated with adding barrel extensions. It is the ideal tool for creating 4-inch openings for plumbing waste lines, dryer vents, and bollard installations.

The 594101504 is built to withstand the rigors of cutting hard reinforced concrete containing abrasive aggregates like granite, flint, and limestone. It features nine heavy-duty diamond segments, laser-welded to the tube for maximum safety and durability. Designed for wet cutting applications with drill motors ranging from 2 to 5 horsepower, this bit offers a "soft start" segment shape that promotes fast drilling speeds from the moment it touches the material. Whether you are a general contractor or a concrete cutting specialist, this extended reach bit provides the reliability needed for your toughest jobs.
