3.5" x 24" B10 Vari-Drill™ Diamond Core Bit | Extended Reach

Part Number: 594101503

Series: B10 Vari-Drill™ (Silver Performance Level)

Product Overview The Husqvarna 594101503 is a high-performance 3.5-inch diamond core drill bit featuring an extended 24-inch tube length, designed specifically for deep-hole drilling applications. Part of the Vari-Drill™ B10 series, this bit is engineered for professional contractors requiring reliable cutting speed and longevity in heavy-duty materials.

Optimized for wet cutting, the B10 series utilizes a specialized bond matrix and laser-welded segments to drill efficiently through hard reinforced concrete, masonry, and stone. The extended reach allows for single-pass drilling of thick walls and floors without the need for extensions.

Key Features & Benefits

• Extended Reach: The 24-inch (610mm) tube length allows for deep drilling applications that standard 14-inch bits cannot reach, reducing the need for barrel extensions.

• Reinforced Concrete Specialist: Engineered to cut through heavy steel reinforcement, hard cured concrete, and hard aggregate with consistent speed.

• Z-Edge Segment Design: Features Husqvarna’s proprietary "roof-top" Z-Edge segments which provide an easier start, reduced vibration, and immediate smooth cutting without a long break-in period

• Laser Welded Segments: Segments are laser welded to the tube (on diameters 2" to 8") to ensure maximum structural integrity and safety during high-stress drilling.

• Silver Performance Grade: A professional "Intermediate" grade tool that offers an excellent balance of cost, cutting speed, and service life.
