9CrSi: Cost-effective basic material, stable cutting performance, matched for conventional medium-low strength rebar, widely used in small & medium construction sites
Cr12MoV: Heavy wear-resistant grade, durable cutting edge, ideal for continuous shear of high-strength rebar
H13: High toughness & anti-crack property, heat resistant, applicable to high-speed cutting, thick rebar and hot rolled rebar processing
Insufficient material toughness: Brittle steel easily cracks when cutting heavy hard rebar; H13 material delivers powerful impact resistance
Improper blade clearance: Unreasonable gap generates uneven stress and damages cutting edges
Defective heat treatment: Residual internal stress shortens service span. Our vacuum heat treatment realizes uniform hardness throughout blades
Wear durability: Cr12MoV achieves 2-3 times longer cutting lifespan than 9CrSi under identical working scenes
Economic performance: 9CrSi lowers upfront purchase cost; Cr12MoV cuts replacement frequency and reduces overall operation cost
Complete size drawing: length, width, thickness and bolt hole parameters
Specified blade material
Actual rebar diameter and strength grade
Rotate blade timely once cutting edge wears dull
Secure mounting bolts tightly to prevent impact damage
Set blade gap around 10% of rebar diameter for stable shearing
Fully eliminate internal residual stress
Consistent hardness HRC 50-62 from core to surface
Remarkably restrain edge cracking and spalling failure
Four-sided cutting design, blade lifespan rises 400% via simple rotation
Universal fit for manual, hydraulic and CNC cutting machines, covers GQ40/GQ50/GQ60 series and mainstream global shear equipment
Uneven blade surface creates vibration chatter, accelerates abrasion and damages machine cutter seat
High-precision grinding ensures tight fitting, absorbs strong impact and safeguards cutting host equipment
