Tool Steel Bar Stock

Tool Steel Round Bars for Tooling & Wear Components

Mozaic Precision Metals supplies tool steel round bar stock and provides grinding and cut-to-length processing for customer specifications. Send your required grade, material condition, dimensions, and quantity for availability and pricing.

Tool steel includes multiple grades with different combinations of wear resistance, toughness, and temperature performance. The appropriate grade depends on the tooling application and planned heat treatment—not every tool steel offers the same properties.

We review inquiries for dies, punches, cutting tools, mould components, and wear parts. Supply and processing requirements are confirmed against your drawing or purchase order.

I would like to receive emails and updates from Mozaic Precision Metals.

Include the exact grade required, such as A2, D2, O1, S7, H13, or M2, rather than specifying “tool steel” alone. Availability is reviewed for the requested size and condition.

State whether you need annealed stock for machining or material in a defined hardened condition. Include any hardness limits, material standards, and certification requirements.

Surface condition also matters. Specify whether you require as-supplied stock, decarb-free material, or a precision ground diameter, and provide the applicable dimensional allowance.

Ground Diameters & Cut-to-Length Blanks

For round tooling blanks and wear components, centerless grinding can prepare the outside diameter to specified dimensions. Saw cutting prepares individual lengths for subsequent machining.

Provide the finished diameter, tolerance, surface finish, and cut-length requirements. If ends will be faced afterward, include the necessary machining allowance.

Plan Processing Around Heat Treatment

Tell us when heat treatment occurs in your manufacturing sequence. Dimensions can change during hardening, so stock intended for machining before heat treatment may need different allowances from material requiring final grinding afterward.

For hardened stock, include the grade, current hardness, incoming dimensions, and remaining finishing allowance so the grinding requirements can be assessed.

Request a Tool Steel Bar Quote

Send your grade, material specification, supplied condition, diameter, length, quantity, and delivery requirements. Include any decarb-free surface requirements, grinding tolerances, hardness limits, or documentation needs.

Mozaic Precision Metals is ISO 9001:2015 certified. Request a quote for tool steel supply and processing, or let us know if you will provide the material.
