Concrete Coring Diamond Core Bits & Professional Drilling Solutions
Discover professional concrete core drilling tools for general wet coring, approved reinforced concrete applications and modular drilling systems. Select the right diamond core bit by material, hole diameter, usable depth and machine connection.
Concrete Coring Applications
Choose a core drilling system according to the material, required hole dimensions and equipment capabilities.
Concrete Slab Coring
Circular holes in cured concrete slabs for suitable construction and utility installations.
Reinforced Concrete Coring
Drilling concrete containing steel reinforcement using equipment and core bits specifically approved for the cutting conditions.
Utility & Pipe Openings
Round openings for suitable pipework, ventilation and building services installations.
Multiple-Diameter Drilling
Drilling projects requiring different hole sizes, barrel lengths and compatible threaded drilling components.
How to Choose a Concrete Diamond Core Bit
Concrete core bit selection should begin with the intended drilling application rather than diameter alone.
- Identify the material. Check whether the project involves standard cured concrete or concrete containing reinforcement.
- Confirm the hole diameter. Select the core bit size according to the required finished opening.
- Determine usable depth. Check the required drilling depth and account for the actual effective cutting length.
- Verify drill compatibility. Confirm spindle thread, available power, operating speed and torque requirements.
- Choose the drilling method. Use wet or dry operation only when approved by the bit and machine manufacturers.
- Check segment construction. Match the cutting segment and attachment system to the intended drilling task.
Wet Concrete Coring vs. Dry Masonry Coring
Wet and dry core bits have different intended materials and operating requirements.
Wet Concrete Core Bits
Wet core drilling is the primary method covered by ALSKAR's concrete core bit ranges.
- For approved concrete and masonry materials
- Water supply provides cooling and slurry management
- Options for professional reinforced concrete coring
- Choose based on diameter, depth and thread
- Follow the drill and core bit instructions
Dry Soft Masonry Core Bits
ALSKAR also offers ARIX dry core bits intended for compatible soft brick, concrete block and soft masonry applications.
- Suitable for specified soft masonry materials
- Requires compatible dry drilling equipment
- Use appropriate dust extraction controls
- Verify the exact spindle and adapter connection
- Not recommended for solid poured concrete or rebar

| Product Series | Diameter | Barrel / Depth | Typical Application | Segment Attachment |
|---|---|---|---|---|
| Standard Wet | 1"–12" | 14" barrel | General wet concrete coring | Silver brazed |
| Premium Wet | 1"–14" | 18" barrel | Professional wet concrete coring | Silver brazed |
| Premium Laser-Welded | 1"–16" | 14" barrel | Concrete and approved reinforcement | Laser welded |
| Premium Three-Piece | 1"–16" target range | Assembly dependent | Modular concrete drilling | Laser welded |
| Supreme ARIX Dry | 1"–6" | 9" effective depth | Soft masonry only; not solid concrete | Laser welded |
Barrel length, overall length and effective drilling depth are not always the same. Never assume the published barrel length is the guaranteed usable drilling depth.
Thread Connections, Depth & Machine Selection
A correctly matched drilling assembly requires more than a suitable cutting segment.
5/8"-11 Connection
Used on selected smaller core bit sizes and compatible equipment. Check the actual male or female thread, pitch and engagement.
1-1/4"-7 Connection
A common professional core drilling connection. Verify the exact spindle, bit connection and machine capacity.
Thread Adapters
Selected adapters can connect matching drilling components. A thread adapter does not make an unsuitable machine or bit safe to use.
Effective Drilling Depth
Consider barrel length, hub dimensions, required drilling reach and core removal procedures for the specific system.
Rotary Core Drilling
Check drill capacity, speed and torque. Do not engage percussion or hammer action on rotary-only diamond core bits.
Modular Assemblies
For three-piece systems, verify every connection, the selected cutting head, the assembled length and machine compatibility.
Thread sizes and specifications vary across regional standards and equipment manufacturers. Check the complete connection designation rather than relying on nominal size alone.
Concrete Core Drilling Safety & Preparation
Concrete coring can involve silica dust, slurry, hidden services, reinforcement and significant drill reaction forces.
Follow the core drill manufacturer's instructions, applicable workplace safety requirements and the project's structural authorization.
Explore Technical Resources →Identify concealed electrical, plumbing and other services before drilling.
Use the correct drill mounting and anchoring method for the job.
Use approved cooling, slurry management and silica exposure controls.
Check segments, barrel, threads and adapters. Do not operate damaged tools.
Frequently Asked Questions
What core bit should I choose for cured concrete?
Select a core bit rated for wet concrete coring and compatible with your drill. Confirm diameter, required depth, aggregate condition, connection and machine operating requirements.
Can all diamond core bits drill reinforced concrete?
No. Use a core bit specifically approved for the reinforcement and intended application. ALSKAR's laser-welded concrete series includes options for approved reinforced concrete drilling. Obtain the required structural authorization.
What is the difference between Standard Wet and Premium Wet?
The ALSKAR Standard Wet series is a general wet concrete drilling option with a 14-inch barrel. The Premium Wet series features an 18-inch barrel and a broader published diameter range. Check the selected configuration for usable depth and machine compatibility.
Can I use a dry masonry core bit for solid concrete?
Do not assume so. The ALSKAR Supreme ARIX Dry series is intended for soft brick, CMU and soft masonry, not solid poured concrete or reinforced concrete.
Are 5/8"-11 and 1-1/4"-7 threads interchangeable?
No. They are different thread standards. A properly rated, compatible adapter may support selected combinations. Verify both connections and the machine specifications.
Does an 18-inch barrel provide 18 inches of effective drilling depth?
Not necessarily. Barrel length, overall tool length and usable drilling depth are different measurements. Confirm the working depth for the exact bit and drilling assembly.
Can I use hammer mode with a diamond core bit?
Not with diamond core bits designed for rotary-only operation. Follow the core bit and drill instructions, including restrictions on percussion.
How can I request a core bit recommendation or wholesale quote?
Provide the drilling material, hole diameter, required depth, drill model, thread connection, quantity and destination through the ALSKAR wholesale inquiry form.
