Drill Deep 4.25 Inch Holes in Hard Concrete with the Husqvarna Extended Reach Core Bit

Tackle deep structural drilling applications with confidence using the Husqvarna 595934205 4.25-Inch Diamond Core Drill Bit. Part of the Silver performance level B10 Vari-Drill series, this bit is engineered to solve the common issue of limited drilling depth. With an extended 24-inch tube length, it allows you to penetrate thick foundations, bridge decks, and heavy masonry walls in a single, continuous pass. This "Extended Core Travel" eliminates the wobble, deviation, and wasted time associated with adding barrel extensions, ensuring a straight, professional finish for your installations.

The 595934205 is designed to master hard reinforced concrete containing abrasive aggregates like granite, flint, and limestone. It features 10 high-performance diamond segments with a specialized "Z-Edge" or roof-top design, which promotes fast, easy starting and smooth cutting even in tough conditions. Laser-welded to the barrel for maximum safety and bond strength, these segments are built to withstand the high torque of deep drilling. Optimized for wet cutting with motors ranging from 2 to 5 horsepower, this bit delivers the reliability needed for creating precise 4.25-inch (108mm) openings for conduit, large piping, and structural anchors.

Key Features

  • 24-Inch Extended Reach: Drills deep holes in one setup without the need for additional extensions.
  • 4.25-Inch Diameter: Precise sizing (108mm) for applications requiring slightly more clearance than 4-inch bits.
  • Vari-Drill B10 Technology: Silver performance level engineered for speed and durability in hard materials.
  • Hard Aggregate Performance: Cuts efficiently through reinforced concrete, granite, flint, and limestone.
  • 10 Laser-Welded Segments: Ensures exceptional segment retention and safety during heavy-duty use.
  • Standard Connection: 1-1/4"-7 thread ensures compatibility with most professional core drill rigs.
  • Fast Start Design: Segment geometry reduces vibration and promotes a smooth start in reinforced concrete.

Pro-Tip: The 4.25-inch diameter is often chosen to provide extra clearance for 4-inch pipes or sleeves, making installation easier than with a tight 4-inch hole. When drilling 24 inches deep with this bit, be sure to pause occasionally to let the water flush out the slurry completely. This helps prevent the bit from binding near the bottom of the cut and extends the life of your diamond segments.
