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.

What's Included:

  • (1) 4.25" x 24" B10 Vari-Drill Diamond Core Bit (595934205)

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.

BNTECHGO 14 Gauge Silicone Wire Spool 40 feet Ultra Flexible High Temp 200 degrees
Size: silicone wire red 20ft and black 20ft, Color: Red and Black
I'm reworking all the interior and exterior electrical wiring, relay's, connections (body grounds as well) on my 1994 GMC K-2500, the original wire did a good service for the 25 years it has been used. I'm disabled and refuse to pay $50,000 for a new truck (it wouldn't run as well as my 1994 anyway) I was hesitant about this brand or wire, but I thought (I'm not supposed to do that) I would give them a chance thanks to the reviews. I was Extremely Pleased at the High Quality of this "Real Copper" wire, not aluminum w/ coated- COPPER !, tinned very well, the silicone insulation is real industrial grade silicone. I run all my wire inside of braided nylon sheathing and securely fasten it every 24", using adhesive lined shrink tubing over all connections- works very well with this wire, it is easy to form for tight turns, lays straight once laid out, soders excellently (the top notch tinning helps there), I now have several hundred feet of 18, 16, 14 and 12 gauge of this VERY High Quality wire (It will be used on my solar system as well now) Thanks again Amazon for another "Top Quality, First Class" product that I can have delivered to my door, 90 miles from town, AND Thanks to everyone who takes the time to review the items we all could benefit from knowing better what the strong and weak points are

Solders nice, extremely flexible maybe too flexible
Size: silicone wire red 20ft and black 20ft, Color: Red and Black
The wire solders very nicely. It's very flexible, perhaps a little too flexible. I used this wire in a couple speaker building projects. I like to put the wire in a drill and twist the wires together, it's a nice look and helps with wire management. The too flexible part makes it so the wire doesn't stay tightly twisted. To remedy that I use heat shrink at either end to at least keep the wires somewhat together.

Quality heat resistant wire.
Size: silicone wire red 25ft and black 25ft, Color: Red and Black
Quality, heat resistant silicone wire for my heating coil wine bottle cutting project. I didn’t need very much, but provided me the best price and option. No regrets.
