An Introduction to Tool Steels for Woodworking

Tool steels refer to the family of specialty carbon and alloy steels engineered to withstand the rigors of machining, pressing, casting, plastic molding, and abrasive polishing work. Key attributes include:

  • Hardness for wear resistance when cutting and shaping
  • Strength to withstand cutting forces without warping
  • Toughness that resists chipping or fracturing under load
  • Stability to hold form across repeated thermal cycles
  • Corrosion resistance in wet woodworking environments
  • Dimensional precision essential for tight-fitting joints and fixtures

These properties make tool steels ideal for the blades, bits, guides, and abrasives needed to shape and finish wood with exactness and efficiency. Optimized grades enhance the quality and precision of wood projects.

The Right Hardness: Sharpness vs. Toughness

A key consideration for any woodworking tool steel is balancing hardness against required toughness:

  • Hardness correlate to wear resistance and edge sharpness. But taken too far, excessive hardness leads to brittleness.
  • Toughness measures a steel’s ability to resist fracturing under load. Greater toughness handles high forces from wood cutting and milling.
  • An optimal combination couples hardness for sharp, durable edges with sufficient fracture resistance against the forces and impacts of woodworking.
  • Minor differences in composition and heat treating fine-tune hardness versus toughness. Molybdenum and cobalt tend to increase toughness. Higher carbon boosts hardness.

The winning balance pairs just enough toughness to complement high hardness. This delivers wood cutting tools and blades that stay sharp without chipping or breaking.

Key Alloying Elements for Woodworking

Various alloying elements refine tool steel properties for woodworking:

  • Carbon forms hard carbides with chromium, vanadium, molybdenum, and tungsten that boost wear resistance. But too much carbon risks brittleness.
  • Chromium enhances corrosion resistance needed in wet wood environments while contributing to hardenability. 13%+ makes stainless grades.
  • Molybdenum improves strength and machinability. In larger amounts, molybdenum contributes wear resistance.
  • Vanadium forms hard vanadium carbides while refining grain size for hardness and strength.
  • Manganese combines with sulfur impurities, improving machinability. Manganese also aids hardening response.
  • Cobalt enables high hardness while maintaining good toughness and sharpenability.

Fine-tuning these elements allows tailoring tool steel to woodworking demands.

Heat Treating Refines Properties

The properties of tool steels fully manifest after proper heat treatment:

  • Hardening through heating and rapid quenching forms martensite to achieve the desired hardness and strength. Oil, water, air, or polymers quench depending on required properties.
  • Tempering follows hardening to relieve stresses and refine hardness. Two or three tempers at progressively lower temperatures optimize toughness.
  • Tavlama requires slowly cooling after heating to soften the steel for improved machinability when fabricating tools.
  • Stress relieving at low temperatures releases locked-in stresses from material processing and machining before final grinding.

When performed skillfully, heat treating unlocks the ideal tool steel properties for woodworking.

Key Tool Steel Grades for Woodworking

Many tool steel types see use for cutting, shaping, and finishing wood:

O1, A2 – Oil Hardening Steel

General purpose tool steel offering a good balance of hardness, toughness, and ease of sharpening. Used for hand tools like chisels and planes.

M2 – High Speed Steel

The original high speed steel. Hardness and red hardness for sharp, long-lasting cutters, saws, drills, and router bits. Cobalt-enriched grades further boost heat resistance.

D2 – Cold Work Steel

A versatile cold work steel hardened by air quenching. Provides excellent hardness for punches and dies when impact forces are minimal.

S1, S5, S7 – Shock Resisting

Added chromium improves toughness and shock resistance for chisels, ax blades, and other high-impact tools.

H13 – Hot Work Steel

Popular as a die steel, H13 also serves well for hot wood bending and laminating presses needing durability at elevated temperatures up to 1000°F (540°C).

420, 440C – Stainless

Corrosion resistant with good hardness and polishability. Used for knives, scrapers, moisture prone jigs, and food contact surfaces.

The optimal grade depends on the woodworking tool function and processes encountered.

Abrasives: Cutting Away Differently

While most woodworking emphasizes removing material in small amounts slowly over many sharpenings, abrasives take the opposite approach. By utilizing huge numbers of hard, sharp points, tool steel abrasives cut away large amounts of material rapidly. Different forms include:


Tiny grains of aluminum oxide, silicon carbide, or garnet adhered to paper rapidly smooth and contour wood. Harder than the particles, the flexible paper backing prevents gouging.


Rows of individually cut teeth made from hardened tool steel rapidly shape wood and rapidly remove stock. Curved, flat, and riffler files suit different applications.

Grinding Wheels

Disks of tool steel with embedded industrial diamond or silicon carbide grits aggressively grind away stock. Bonded composites balance cutting action and wheel integrity.

Burrs and Rotary Rasps

Small, coarse grain tungsten carbide or industrial diamond burrs and rasps quickly remove wood for shaping and deburring. Stainless steel shanks support the abrasive tips.

Tool steel delivers both the soft matrix supporting cutting grains and the durable sharp particles themselves for rapid abrasive action.

Precision in Fixtures and Guides

Beyond cutting, tool steels construct the guides, gauges, and fixtures that enable precision wood joinery and assembly:

  • Linear guides keep cutting tools running true. Tool steel maintains slide accuracy despite sawdust and debris.
  • Close tolerance drill bushings guarantee precision hole placement. Stainless steel resists moisture and remains dimensionally stable.
  • Durable jig plates and workholding fixtures withstand clamping forces and machining over time. Precision ground to avoid any warp or twist.
  • Thin feeler gauges consistently measure tiny gaps for perfect fit joints. Rust-resistant tool steel retains stiffness without bending.
  • Interchangeable router templates guarantee uniformly shaped decorative edges and cutouts. Wear resistance maintains clean contours.

The rigidity, corrosion resistance, and dimensional stability of tool steels enable woodworking precision of the highest caliber.

Takım Çeliği for the Woodturner

On the lathe, tool steels construct cutting implements able to shear, slice, and peel wood with finesse:

Cutting Edges

Parting tools, skews, gouges, and scrapers involve high-speed or stainless tool steel edges expertly sharpened for turning. Durable, fine-grained alloys maintain the keen edge.

Support Shanks

Stainless or tool steel shanks secure carbide, ceramic, or specialty steel cutters to withstand centrifugal forces while damping vibration. Precision cylindrical forms fit chucks and tool rests.

Specialty Inserts

Indexable carbide, ceramic, CBN, and exotic alloy inserts attach to tool steel shanks for replaceable cutters. Complex tipped profiles shape intricate profiles not possible through grinding alone.

Lathe Chisels

Woodturning chisels require a keen, strong edge. Tool steel’s hardness optimizes sharpness. Alloying additions boost fracture resistance against lathe catches.

On the lathe, tool steel combines strength, vibration resistance, and machinability to support specialized cutters and deliver smooth turning.

Why is toughness important for tool steels used in woodworking?

The cutting forces encountered when shaping wood can fracture a tool steel that is too brittle. Toughness indicates a tool steel’s resistance to fracturing under load. A measure of impact strength, sufficient toughness ensures cutting edges can withstand intermittent forces from dense knots, grains changes, or catches when woodturning without chipping or breaking prematurely.

How do tool steels used for woodworking abrasives differ from cutting tool steels?

Abrasive tool steels act as a hard matrix to support sharp abrasive grains that cut away large amounts of material. The matrix needs consistent hardness to avoid gouging. By contrast, cutting tool steels require keen, shaped edges and enough toughness to resist fracturing under wood cutting forces. The tool steel properties are tailored to the different needs.
