Heavy-Duty Excavator Hydraulic Shear Blades & Eagle Snout Knives

ALAS manufactures precision-machined, drop-in replacement blades for all critical wear zones on hydraulic shear jaws. Engineered from 100% virgin tool steel and treated via computer-controlled vacuum quenching, our blades deliver maximum cutting force and minimized downtime during high-tonnage scrap recycling and heavy demolition.

Jaw Layout & Blade Range

We supply the full jaw components to prevent material jamming and maintain an optimal cutting profile:

• Upper Primary & Secondary Blades: High dimensional stability for continuous heavy structural steel cutting.

• Lower Primary & Secondary Blades: Strict flatness control to maintain consistent shearing clearance.

• Piercing Tips / Nose Blades: Reinforced geometry engineered to withstand extreme point-loads during initial plate penetration.

• Guide & Cross Blades: Precise tolerance alignment to stabilize tracking and eliminate material jamming.

Technical Specifications & Material Guide

To prevent premature cracking and edge rolling, ALAS utilizes certified virgin tool steel billets (H13, Modified H13K, and X45) matched to your specific demolition loads.

Metallurgy Comparison Matrix

Advanced In-House Heat Treatment & Toughening

• Integral Vacuum Heat Treatment: Specialized vacuum quenching eliminates surface oxidation, decarburization, and soft spots, achieving uniform through-hardness from the surface to the core.

• Low-Temperature Tempering (180–220°C): Removes residual micro-stresses from CNC grinding, preventing brittle fracturing under sudden hydraulic shock loads.

Compatibility & Engineering Advantages

1. 100% OEM Drop-In Compatibility

All blades are machined strictly to factory blueprint dimensions for direct on-site replacement without welding or field modifications.

• Direct Fitment For: Genesis (GXP, GXT, GMS), LaBounty (MSD series 1000, 1500, 2000, 2500, 3000, 4000, 4500, 7500), Stanley, NPK, Caterpillar, Okada, and other mainstream global shear attachments.

• Precision Alignment: Machined within ±0.02mm tolerance for bolt hole centerlines, counterbore depths, and flatness to ensure zero-gap seat positioning.

2. Core Product Features

• 4 Usable Cutting Edges: Rectangular indexable configuration allows up to four rotations before requiring a regrind.

• Optimized Piercing Geometry: Smooth plate penetration minimizes high-frequency vibration feedback to the excavator arm and cylinders.

• Hardware Turnkey Bundles: Complete setups available with high-strength mounting bolts, locking fasteners, and precision shim kits to maintain correct cutting clearance.

Why Choose ALAS?

• Calibrated Hardness Profile: Multi-point HRC testing ensures optimal hardness (HRC 48–56) without brittle cutting edges.

• Clean Shear Performance: Straight, burr-free cuts on high-tensile steel and I-beams, reducing secondary sorting or torch rework.

• Fast Customization: Blueprint confirmation and material matching quotes issued within 24 hours based on your equipment model or physical sample.

Frequently Asked Questions

Q1: Which material should I choose between H13, H13K, and X45 for my excavator shear?

• X45 provides maximum shock toughness and high resistance to chipping, making it ideal for mixed irregular scrap and light-to-medium demolition.

• H13 is the B2B benchmark for general scrap yards, balancing core toughness and continuous wear life under heavy impact.

• H13K is built for ultra-large shears (≥180T) and extreme tasks like bridge demolition or thick alloy profile cutting, delivering 20% to 30% longer service life than standard H13.

Q2: Are your blades directly compatible with OEM brands like LaBounty and Genesis?

• Yes. All ALAS replacement blades match standard OEM coordinates. Bolt hole layouts and alignment surfaces are CNC-machined within ±0.02mm, allowing a direct drop-in installation on-site.

Q3: How many cutting edges do your rectangular shear knives have?

• Our straight primary and secondary blades feature 4 usable cutting edges. Operators can rotate the blade 90 degrees to a fresh edge when worn, quadrupling the tool utility before replacement.

Q4: Why do some shear blades crack prematurely, and how does ALAS solve this?

• Premature failure stems from internal gas porosity in cheap recycled steel or residual stress from flame hardening. ALAS uses 100% virgin tool steel billets and computer-controlled vacuum quenching followed by multi-stage tempering to ensure uniform core hardness and eliminate internal micro-cracks.

Q5: Do you provide the complete replacement kit including bolts and shims?

• Yes. We supply full maintenance packages including matching guide blades, piercing tips, high-strength mounting fasteners, and precision adjustment shims to keep your blade clearance tightly calibrated.

Q6: Can you custom manufacture blades based on our specific drawings or dimensions?

• Yes. We provide comprehensive OEM/ODM contract manufacturing. Send us your technical drawings or part numbers, and our engineering team will provide custom blueprint sign-offs within 24 hours.
