Product Navigation
Find the right tooling family before you send an RFQ.
HEYI products are organized by tooling technology and application fit. Start with the family below, or send a full RFQ when the job depends on drawing, material, tolerance, machine condition, or current tool failure.
CBN Tools
For hard turning, cast iron, brake components, rolls, bearings, and grinding-replacement applications where stable wear is critical.
Carbide Tools
For boring, reaming, turning, grooving, and general precision machining where practical reliability and dimensional control drive the decision.
Custom Tooling
For non-standard geometry, special clamping, insert pocket fit, reach limits, and tooling developed around a real process constraint.
When to use Full RFQ
Use Full RFQ when you already have drawing, material, hardness, current cutting data, current tool life, or a specific target result. Use Contact Us when you need a quick first conversation before preparing the technical package.
