The small H13 tool-steel die block costs $548.89 for one, $125.39 each at 10, and $91.10 each at 100 pieces. H13’s slow cutting rate makes machine minutes and tooling more important than the stock line, while setup and inspection set the prototype floor. State whether heat treatment and grinding follow machining. A die block may also need stress relief, hardening, wire EDM or grinding after this route.

The H13 tool steel, annealed example part
The reference block is 4 × 3 × 1 inches with a pocket and six holes. H13 is chosen for hot-work tooling, but the example part is not a mold design and carries no hardening specification. A real die may need electrode work, deep ribs, pre-hard stock or a finish grind that adds substantial time.
How the quantity break works
Slow removal rates reward careful planning. Tool selection, coolant, corner radii and a stable workholding plan protect the cutter and the part. Our pricing engine expresses that effect through machinability; it does not predict a particular insert life or guarantee a surface finish.
What the material or process changes
One piece still carries CAM and setup. A ten-piece lot spreads those fixed minutes, while a 100-piece lot may justify dedicated workholding or a different stock-buying pattern. If a toolmaker changes from annealed H13 to pre-hard P20 or D2, rerun both stock and cycle.
How to turn this into a firm quote
State the hardness condition, heat-treat sequence, dimensional allowance and inspection method. Tool steel quotes become reliable when the post-machining work is explicit instead of hidden under a single “steel surcharge.”
Questions to settle before release
Ask for hardness, heat-treatment sequence, stock allowance, polish requirement and any EDM or waterline feature before quoting H13. Confirm whether the block needs a certified flatness report and what datum the toolmaker will inspect. Tool steel work often has a long feedback loop; include prove-out and rework risk as explicit operations when the drawing is not mature. The computed table is the baseline routing.
For this cost to machine tool steel estimate, the estimate is strongest when the handoff includes the drawing revision, stock quote date and acceptance plan. Save those details with the quantity break. If the buyer changes one requirement, rerun the affected operation and leave the other lines intact. This keeps a revision discussion factual and prevents an old material or finish assumption from surviving in a new price.
Pricing engine output for the stated Tool steel H13, annealed CNC milling example part
- • Material: Tool steel H13, annealed; the US catalog stores its small-lot price and machinability factor.
- • Process: CNC milling; setup, machine time, deburring and inspection are generated from the example-part geometry.
- • Markup: 30% default US catalog markup; quantities are 1, 10, 100.
- • Fictional 4 × 3 × 1 in milled block; no finish or outside process.
- • No outside finish, tax, freight, or customer-specific rate is included.
- • These are computed examples, not supplier quotes or market averages.
