The Challenge
What Construction Crews Struggle With
Three pain points we hear from contractors in 40+ countries - and the tooling that solves them.
Cutting Reinforced Concrete
Steel rebar blunts ordinary blades; cuts stall, overheat, and burn through segments on every structural job.
Dust & Vibration on Site
Dry cutting spreads dust and vibration that disrupt occupied buildings and fail site safety rules.
Precision & Speed for Retrofit
Openings must be exact and fast to keep the build schedule - sloppy cuts mean rework and delay.

Recommended Tool by Material
Segment type and cutting mode change with the job. Use this as a starting point; our engineers fine-tune per machine.
| Material | Blade / Type | Segment | Cutting Mode |
|---|---|---|---|
| Reinforced Concrete | Laser-welded | Turbo / Segmented | Wet |
| Asphalt | Asphalt Blade | Undercut segments | Wet / Dry |
| Brick / Masonry | Turbo Blade | Standard | Dry / Wet |
| Green Concrete | Soft Bond Blade | Segmented | Wet |
Technical Tips for Construction Cutting
1
Wet Cut Reinforced Concrete
Water cools the segment and flushes slurry, extending blade life through rebar without burning.
2
Use Laser-Welded Blades
Only laser-welded segments survive the impact of hitting rebar - brazed segments shatter.
3
Core Drill with Steady Pressure
Let the bit cut; excessive force cracks the barrel or jams the core inside the hole.
4
Match Segment to Material
Hard bond for abrasive asphalt; soft bond for hard concrete. Wrong bond wastes the job.

FAQ
Construction Cutting Questions
Best blade for reinforced concrete?
A laser-welded turbo or segmented blade, wet cutting, with a soft bond for hard concrete and rebar.
Can diamond blades cut rebar?
Yes - with laser-welded blades and wet cutting. Avoid forcing through heavy rebar to protect the segment.
Wet or dry construction cutting?
Wet is preferred for concrete (dust + cooling); dry works for masonry and asphalt with extraction.
Which core bit for concrete with rebar?
A wet laser-welded core bit with high diamond concentration and segmented slots for slurry exit.
Do you make wall saw / ring saw blades?
Yes - custom diameters and segments for wall and ring saws, matched to your machine.
What is the MOQ for construction tools?
Flexible MOQ from 50pcs per specification. Trial orders at lower quantities are accepted for new distributors.
