When creating custom tooling profiles, executing deep parting operations, or machining high-tolerance guide pins requires the finest metallurgical substrates, Outils Clarkson-Osborn delivers. As Canada’s leading supplier of industrial-grade tool room materials, we supply a massive inventory of high-speed steel (HSS) tool bits, cobalt parting-off blades, and precision-ground drill rods. Engineered to provide exceptional toughness, edge retention, and thermal resistance, our material blanks allow your machinists to grind, cut, and form high-performance custom tooling tailored to your exact manufacturing blueprints.
Explore our comprehensive technical inventory of toolroom essentials. Whether your operation requires premium M2 or M42 cobalt squares for heavy-duty lathe turning, T-shaped cut-off blades for rigid parting passes, or oil-hardening drill rods for custom punch production, we stock the premium raw materials required to support your facility’s custom fabrication demands.

Production-Grade Toolroom Blanks and Precision Ground Steels
Relying on subpar material substrates for custom cutting tools leads to rapid edge dulling, poor surface finishes, or catastrophic structural fracturing under load. Our catalog features premium-melt tool steels and high-speed alloys, precision-ground and heat-treated to ensure predictable performance when grinding custom profiles or machining precision shafts.
Specialized Material Categories & Tool Geometries
High-Speed Steel & Cobalt Tool Bits: The ultimate canvas for the manual machinist or custom toolmaker. Available in square, round, and flat profiles, these premium blanks (ranging from standard M2 HSS to 10% cobalt M42) are designed to be custom-ground into specialized turning, boring, facing, or threading bits for lathe applications.
Parting-Off & Cut-Off Blades: Engineered specifically for deep grooving and slicing operations on conventional or automated lathe systems. Available in bevel or advanced T-shape profiles, these high-tensile blades provide maximal side clearance, structural rigidity, and heat dissipation to prevent binding during deep plunging cuts.
Precision Drill Rods: High-carbon tool steel rounds ground to strict diameter tolerances with a mirror-like finish. Available in water-hardening (W1), oil-hardening (O1), or air-hardening (A2) specifications, drill rods are the standard choice for manufacturing custom dowel pins, punches, taps, rollers, and die components.
Understanding Tool Steel Metallurgy (M2 vs. M42 vs. O1)
Selecting the ideal composition ensures your custom tools can withstand specific operating temperatures and impact stresses:
M2 High-Speed Steel (HSS): The industry standard for general-purpose custom cutting tools. It offers an exceptional balance of wear resistance, high structural toughness, and cost-effectiveness.
M42 Cobalt Steel: Enhanced with an 8% cobalt matrix, providing elite “red-hardness.” This metallurgy allows the cutting edge to stay razor-sharp even when subjected to intense friction and thermal loads from machining stainless steel or titanium alloys.
O1 Tool Steel: A premier choice for non-cutting components, alignment pins, and forming tools. It provides high dimensional stability during oil-quenching heat treatments, resulting in an exceptionally hard, wear-resistant outer shell.
Selecting the Material Blank: Formulations & Applications
To achieve peak tool life and prevent premature chipping or tool wear, match your specific application to the correct toolroom substrate:

Frequently Asked Questions
A T-shaped parting blade features a cross-section where the top face is wider than the lower body. This precision-ground geometry provides built-in longitudinal clearance along the side walls of the groove. It completely prevents the blade from rubbing against the sides of the cut as it plunges deep into a workpiece, drastically reducing heat buildup, binding, and tooth scoring.
Yes. Standard white or pink aluminum oxide wheels are suitable for grinding and shaping high-speed steel and cobalt tool bits. However, because cobalt alloys feature incredible red-hardness, you must grind with light, uniform pressure and dip the tool bit into water frequently to prevent localized overheating, which can introduce micro-cracks into the carbide matrix.
Our precision drill rods are supplied in a fully annealed, soft state. This allows your toolmakers to easily saw, turn, mill, or file the material into the desired custom component configuration using standard machine tools. Once the final shape is completed, the part can be heat-treated (oil, water, or air-quenched depending on the specific steel grade) to achieve its final target hardness.
