Maximizing Performance with High-Quality Replacement Chipper Blades
In wood processing or land-clearing work, chipper blades are the most important parts that affect how well your machine works. A good blade not only cuts wood easily—it also saves fuel, eases strain on your engine, reduces downtime, and makes better wood chips.
Our industrial wood chipper blades are perfect replacements for major brands, including Vermeer, Bandit, Morbark, and more. We provide a comprehensive wood chipper blades list for various machine models
What Are Chipper Blades?
Chipper blades are the main cutting parts of wood chippers. They cut:
Logs
Branches
Bark
Recycled wood
They turn these materials into evenly sized wood chips. You’ll find them in industries like:
Types of Chipper Blades
1. Disc Blades
Attached to a rotating cutter head
Common setups: 4–6 blades, 8–12 blades, or spiral design
Good for large logs
Makes clean, high-quality chips
Mostly used by paper mills
2. Drum Blades
Fixed to a cylindrical drum
Works well with mixed materials (bark, wood waste, small logs)
Good for small-to-medium processing plants
Chips are slightly less even than disc blades
Common Chipper Blade Materials
The three main materials for chipper blades are A8, A8B, and D2. They differ in toughness, wear resistance, hardness, and cost.
Material Details & Performance
A8
Type: High-toughness steel
Best for: Toughness and impact resistance
Hardness: HRC 58–62
Good for: Small-to-medium chippers, cutting hardwood, knotty wood, or frozen wood
A8B (Modified A8)
Type: Upgraded A8 steel
Best for: Balance of toughness and wear resistance
Hardness: HRC 58–62 (more consistent)
Good for: Medium-to-large production lines (papermaking, wood panels)
D2
Type: High-carbon, high-chromium steel (semi-stainless)
Best for: Wear resistance and long service life
Hardness: HRC 60–62
Good for: Large machines cutting softwood, bamboo, or straw
Built for the Forest: ALAS Chipper Blades
Superior Steel for Hardwood & Frozen Wood
Cutting hardwood or frozen logs puts a lot of stress on blades.
ALAS blades use Modified A8 steel—perfect balance of hardness and toughness.
No brittle breaking (common with cheap blades).
Works well even in harsh winter conditions.
Save Money with ALAS Engineering
The real cost of a blade isn’t just the purchase price—it’s downtime.
ALAS helps you choose the right blade (size, material) for your wood type.
Longer blade life means fewer replacements and less downtime.
Lowers your total cost of ownership (TCO).
How to Choose the Right Blade
Mixed materials, high impact (hardwood, knotty wood, frozen wood) → Choose A8
Continuous production, mostly hardwood → Choose A8B (best value)
Softwood, bamboo, high volume → Choose D2 (longest life)
A good replacement chipper blade improves chip quality, saves fuel, and makes your machine work better.

Chipper Blades FAQ (Frequently Asked Questions)
1. What materials are your chipper blades made of?
We offer premium tool steel options, each optimized for different working conditions to meet your specific needs:
A8 / A8 Modified: The gold standard for chipper blades. It delivers the best balance of toughness and wear resistance, effectively preventing chipping during operation.
D2 (SKD-11): High carbon and high chrome steel, designed for maximum edge retention—ideal for applications with clean wood (no debris or contaminants).
Cr12MoV: A cost-effective choice, perfect for standard landscaping and brush chipping tasks.
2. How often should I sharpen or replace my chipper knives?
Blade life varies based on the type of wood being chipped and its cleanliness (e.g., presence of dirt, rocks, or metal). As a general guideline, inspect your blades every 8–15 hours of operation.
Sharpen: When you notice "stringy" wood chips or excessive wood dust (signs the blade is dull).
Replace: When the blade has reached its minimum width limit, or if it has deep cracks/chips that cannot be ground out (these compromise safety and performance).
3. Are your blades compatible with major brands?
Yes. We manufacture precision replacement blades that are compatible with major global chipper brands, including:
Vermeer, Bandit, Morbark, Woodchuck, Echo Bear Cat, and Gravely.
Additionally, we can produce custom blades based on your specific drawings or OEM part numbers.
4. What is the hardness level (HRC) of your blades?
Our chipper blades undergo advanced vacuum heat treatment, typically achieving a hardness of 55–59 HRC. This range is carefully selected to ensure:
5. Can I get a custom size for my industrial machine?
Absolutely. We specialize in OEM/ODM services for custom chipper blades. To get started:
Provide us with the blade dimensions (Length x Width x Thickness), hole diameter, and hole spacing; or
Send us a sample of your existing blade.
We will provide a technical drawing for your approval before starting production, ensuring the custom blade fits your industrial machine perfectly.
