4.5 inch segmented diamond blade for heavy cutting, wall chasing and demolition. Wide slots ensure great cooling & chip removal for site dry cutting. Thick impact-proof diamond segments extend service life. Comes with a 20mm reducing ring for all 115 angle grinders, dry & wet usable for masonry rough work.

Specifications:

Size 1: Outer Dia 115mm(4.5"), Arbor 22.23mm, Segment Width 10mm, Core Thickness 1.4mm

Size 2: Outer Dia 125mm(5"), Arbor 22.23mm, Segment Width 10mm, Core Thickness 1.4mm

Craft: High-temperature alloy powder sintering
Compatible Machine: Hand-held angle grinder
Cutting Mode: Dry and Wet Cutting Available

Applicable Materials:

Compatible materials (mainly for hard civil construction rough materials)  
Solid red bricks, high-strength concrete, cement beams and columns, cement mortar layers, curbstones, thick natural stone, cement lintels, layers of old walls to be removed.

Application Scenarios:

Wall channelling and floor groove cutting for water and electricity renovation; 
Old house demolition: removing old tile cement layers and scraping off hardened wall mortar; 
Civil construction: cutting thick concrete, solid brick, and rough trimming curbstones; 
Rough stone processing: cutting thick stones and rough trimming, no need for fine edging

Notes for Use:

Not for fine cutting of tiles, rock slabs, microcrystalline glass; severe edge chipping will occur.
Avoid sustained heavy pressure cutting; feed evenly to reduce overheating loss. 
Single dry cutting duration ≤60 seconds, cool down 10 seconds intermittently to protect diamond segments. 
Only cut designated masonry materials; never cut metal, wood, glass or plastic. 
Wear full safety gear (goggles, dust mask, gloves) during operation; keep blade vertical while cutting. 

Core Advantages:

High-efficiency rough cutting: Outperforms standard blades on concrete and solid brick, ideal for wall grooving and renovation demolition.
Excellent cooling & chip removal: Wide segmented slots support long dry cutting at waterless construction sites, less blade wear.
Heavy-duty impact-resistant segments: Tolerate heavy feeding, angled grooving and cement scraping, not easy to chip.
Wide material compatibility: Works for concrete, bricks, thick stone and all cement construction components.
Triple heat dissipation design: Slows diamond shedding under high temperature, longer lifespan than continuous/turbo blades.
