Product Selection FAQs
Start with the material and application before comparing tool specifications.
How do I choose the right diamond saw blade?
Identify the material you need to cut, the saw type, blade diameter, arbor connection, operating speed and required wet or dry method. Then select a blade with the appropriate diamond bond and rim construction.
See our Diamond Blade Selection Guide .
Can I use the same diamond blade for concrete and asphalt?
Only when the exact blade is approved for both materials. Concrete and asphalt have different cutting characteristics, and abrasive asphalt applications may require specialized bonds and undercut protection.
Compare our Concrete Cutting and Asphalt Cutting application guides.
Are all laser-welded diamond blades suitable for reinforced concrete?
No. Laser welding describes a segment attachment method; it does not automatically establish rebar compatibility. Select a blade specifically rated for reinforced concrete.
What is the difference between wet and dry diamond core bits?
Wet concrete core bits are used with an approved water supply for cooling and slurry removal. Dry core bits are designed for particular dry drilling materials and methods. They are not universally interchangeable.
Read the Diamond Core Bit Selection Guide .
Can ALSKAR dry masonry core bits drill reinforced concrete?
The ALSKAR Supreme ARIX Dry Masonry Core Bit series is intended for suitable soft brick, CMU and soft masonry. It is not recommended for solid poured concrete or reinforced concrete.
For approved reinforced concrete applications, review the appropriate wet laser-welded concrete core bit series.
How do I select grinding bond hardness?
As a starting principle, harder concrete generally calls for a softer grinding bond, while softer and more abrasive concrete generally calls for a harder bond.
Bond selection also depends on the machine, abrasive properties and grinding conditions. See the Grinding Tool Guide .
What are PCD coating removal tools used for?
PCD tools use polycrystalline diamond cutting elements for suitable coating removal applications. They are different from conventional metal-bond grinding tools and are not intended as general concrete polishing tools.
Tool selection depends on coating type, thickness, machine and the need to protect the underlying concrete surface.
Machine Compatibility FAQs
Matching only a tool's diameter or general shape is not enough.
How can I verify that a diamond blade fits my saw?
Check the saw manufacturer's permitted blade diameter, arbor, flange arrangement, maximum operating speed, guard and approved blade type.
Never exceed the blade's marked maximum RPM or modify its mounting hole to force compatibility.
What is the difference between 5/8"-11 and 1-1/4"-7 core bit connections?
They are different threaded connections with distinct dimensions and pitches. Verify the machine spindle, thread form, male/female connection and any approved adapter before ordering.
See our Core Bit Guide for additional information.
Are Redi Lock, HTC EZchange and Scanmaskin mounting systems interchangeable?
No. These are distinct tool mounting systems. The selected grinding shoe must fit the exact installed holder and approved machine model.
See our Grinding Tool Guide for mounting considerations.
Can I use a diamond core bit with hammer mode?
Do not use hammer or percussion mode with diamond core bits intended for rotation-only drilling. Follow the specific core bit and drilling machine instructions.
What information helps verify product compatibility?
Provide your equipment manufacturer and model, intended material, required dimensions, connection type and operating method. Photos of the existing tool or holder may also help.
