How to Choose the Right Planer Blades for Your Woodworking Projects
If you’re into woodworking, the quality of your surface finish often comes down to one thing—planer blades. Pick the wrong ones, and you’ll spend more time sanding than cutting. The right blades, though, can save you effort, boost efficiency, and last much longer.
You’ll find all kinds of planer blades on the market—made from different materials, with various shapes and coatings. The most popular types include HSS (High-Speed Steel), Solid Tungsten Carbide, and TCT (Tungsten Carbide Tipped). There are also indexable blades that let you rotate or replace the cutting edge without sharpening, making maintenance a breeze.
Of course, what works best depends on your tool. A jointer, bench planer, electric hand planer, or manual hand planer all use different styles of blades, based on how they’re built and how the blades are mounted.
In this article, you’ll learn the pros and cons of each type of planer blade—so you can find the right one for your setup and the kind of woodworking you do.

Types of Planer Blades
Planer blades are categorized into several types: High-Speed Steel (HSS) planer blades, solid tungsten carbide planer blades, Tungsten Carbide Tipped (TCT) planer blades, and indexable carbide inserts.
HSS Planer blades
HSS planer blades are a classic choice for both home and professional workshops. Made from high-alloy steel with elements like tungsten and molybdenum, they offer excellent toughness, sharpness, and affordability. These blades are ideal for planing softwoods and are easy to resharpen.
Pros:
- Budget-friendly
- Easy to maintain and resharpen
- Good for general-purpose use
Best for: Softwoods, moderate workloads, and occasional use
Solid carbide planer blades
Solid carbide planer blades are engineered for heavy-duty applications. With extreme hardness and resistance to heat and wear, they’re perfect for abrasive materials and long production runs. However, they are more brittle than HSS and more difficult to sharpen.
Pros:
Superior wear resistance and edge retention
Withstands high cutting temperatures
Ideal for high-volume and hardwood processing
Best for: Hardwood, MDF, laminated wood, and long production cycles
TCT planer blades
TCT blades feature a steel body with tungsten carbide cutting edges. They offer a balance between durability and cost, making them a common choice for professionals who need longer-lasting blades but want to avoid the high price of solid carbide.
Pros:
More durable than HSS
More affordable than solid carbide
Delivers clean, consistent cuts
Best for: Mixed materials, workshops with mid-to-high workloads
Indexable Carbide Inserts
Indexable inserts are small, square or round blades mounted on helical cutterheads. When one edge dulls, simply rotate the insert to a fresh cutting edge—no sharpening required. This system minimizes downtime and ensures consistent performance.
Pros:
- Extremely long service life
- Easy to replace or rotate
- Excellent surface finish with minimal tear-out
Best for: Professional CNC routers, industrial planer machines, high-efficiency shops
How to Choose the Right Planer Blade?
When selecting planer blades, consider the following factors:
- Wood Type: Hardwoods require tougher blades like carbide or TCT, while softwoods are well-suited to HSS.
- Tool Compatibility: Not all blades fit all planers. Check your machine’s specifications before buying.
- Cutting Volume: High-output environments benefit from carbide or indexable inserts for reduced maintenance.
- Budget: HSS is affordable upfront; carbide offers long-term savings despite a higher initial cost.
- Desired Finish: For a smoother surface, go with carbide-tipped or indexable inserts.
The right planer blade depends on what you’re cutting, how often you’re working, and the finish you want to achieve. HSS blades are economical and great for beginners. TCT blades offer durability at a fair price. For heavy-duty or precision work, solid carbide and indexable inserts are your best allies.
