Technical Specifications Table
Product Overview
Diamond Products’ Heavy Duty Orange Dry Hole Saw Core Bore Bits DH are crafted for maximum productivity and durability. These dry bits require no water, making them ideal for site conditions where wet drilling is impractical. The bits feature a 9-inch drilling depth and a universal 5/8"-11 threaded hub, offering easy attachment to hand-held rotary drills or core rigs. The segment slots in the core barrel help with cooling and debris ejection, ensuring longer tool life and smoother cuts throughout repetitive use.
Key Features
-
Premium Diamond Segments: Ensures high cutting speed and extended lifespan, even in abrasive block and clay brick materials.
-
DH Bond: Optimized for dry coring in block and soft brick but not recommended for concrete, as the tool is tailored for lower compressive strengths and quicker dust evacuation.
-
9-Inch Drilling Depth: Allows for deep penetrations, especially when coring holes for pipes, conduit, or masonry anchors.
-
Universal Hub: 5/8"-11 threaded hub fits most professional hand-held rotary drills and core rigs; Jacobs Chuck adapters are available for compatibility with straight shank drills.
-
Segment Cooling Slots: Barrel slots aid cooling without water, enabling safe and productive dry coring at fast drill speeds.
-
No Water Requirement: Keeps jobsites cleaner and eliminates slurry management, ideal for interior renovation, electrical, and plumbing applications.
-
Wide Size Range: Available in diameters from 7/8” to 6”, with corresponding minimum drill amp requirements to optimize speed and control.
Performance and Benefits
-
Fast, Dust-Minimized Coring: DH bits deliver high drill speeds and excellent coring life, while slots facilitate dust removal for clean, dry drilling.
-
No Water—No Slurry: Ideal for indoor jobs in finished spaces, hospitals, schools, or offices, where water use is not permitted and dust control is crucial.
-
Long Life: Segments are engineered for wear resistance, reducing downtime and replacement costs for busy professionals.
-
Easy Adaptability: Jacobs Chuck adapters allow fast switching between rotary and core drills, maximizing versatility for varied job types.
Typical Applications
-
Electrical and Plumbing Installations: Quick and precise dry holes for conduit, pipe, or junction boxes in block/brick walls.
-
Anchoring and Fasteners: Drilling core holes for rebar dowels, sleeve anchors, or masonry fasteners.
-
Renovation and Retrofit: Ideal for retrofitting projects in occupied or restricted-access buildings.
-
Masonry Construction: Pipe port drilling in new masonry walls without water mess or cleanup.
Maintenance Guidelines
-
Segment Inspection: Check diamond segments before each use for cracks or wear; replace bit if segment loss occurs.
-
Cooling Management: If the bit heats excessively, pause to let it cool or reduce drill speed. Avoid overheating, as it may damage both bit and drill.
-
Dust Removal: Clean debris slots after heavy drilling sessions to ensure cooling and dust evacuation efficiency.
-
Adapter Care: Inspect thread and adapter regularly; lubricate to prevent galling and to maintain easy installation/removal.
-
RPM Control: Operate within indicated RPM limits per diameter to maximize life and ensure safe, effective coring.
Operator Tips for Best Results
-
Do not use hammer action: Only use rotation mode; hammering action can crack segment bonds or damage core bits.
-
Start at low pressure: Use gentle, steady pressure until the bit seats; then maintain moderate pressure for consistent core and longer bit life.
-
Guide with pilot holes: For larger diameters, start with a pilot hole for precise placement and control.
-
Choose the correct diameter before coring: Enlarging a hole with core bits is difficult and can risk damaging the bit or masonry.
-
Maintain alignment and levelness: Ensure the bit stays perpendicular to the wall and follow guides to avoid wandering or misaligned cores.
Frequently Asked Questions
Q: Can I use DH bits on concrete or rebar?
A: No; DH bits are rated for block and soft brick and are not suitable for concrete or rebar-cored materials.
Q: What is the recommended drill power?
A: A 6–10 amp rotary drill, depending on bit diameter; higher diameters need greater amperage for safe/effective coring.
Q: Do I need a specific drill adapter?
A: Standard hub fits 5/8"-11 thread. Adapters for Jacobs Chuck allow use with straight shank rotary drills.
Q: How do I reduce overheating?
A: Drill in short intervals; clean out dust slots, reduce pressure, pause for cooling, and use RPM within limits.
