High-speed steel (HSS) rod
Sourcing for cutting tools, punches and dies
High-speed steels are used in cutting tools and wear-resistant tooling. We review sourcing against JIS grade names such as SKH51 and SKH55, bar dimensions and delivery condition.

Product & application
We review the balance between wear resistance and toughness around operating temperature, wear and impact/chipping conditions. Specify whether annealed stock is needed for machining or grinding, and whether heat treatment will be performed by the customer. M2/M35 and JIS designations are not treated as automatically equivalent.
- Supply forms
- Round rod · cut blanks · ground finish by inquiry
- Application examples
- Cutting tools such as drills, taps and reamers; punches, heading and drawing tooling
Define the supply conditions.
These are specification inputs for quotation review. Actual availability, minimum quantity and lead time are confirmed by grade and size.
- Condition & surface
- Annealed delivery condition, subsequent heat treatment and target hardness
- Dimensions & order
- Bar dimensions, tolerance, grinding allowance and sample quantity
- Inspection & documents
- Specify mill certificates, tests, traceability and customer approvals. Document availability, cost and timing are reviewed.
Representative grades & review scope
| Family | Representative grades / review basis |
|---|---|
| JIS inquiry grades | SKH51 · SKH55 |
| Other designations | M2 and M35 requests require standard and chemistry comparison |
Grades and forms are inquiry examples. Inventory, availability, dimensions, quantity, inspections and lead time are confirmed at quotation.
JIS names are used as a reference. They do not automatically establish equivalence to other standards or certification. Agree the applicable standard, edition and product requirements before ordering.
