KENFA boring tools include small aperture boring bars, profiling boring tools, thread boring tools, slot boring tools and chamfered inner-hole tools for stainless steel, steel, cast iron, copper, aluminum and alloy materials. Buyers should confirm hole diameter, depth, material, holder type and 58-degree or 65-degree design before selection.
Which boring tool family fits the machining problem?
Select by hole diameter, depth, profile and material. Small aperture boring tools require model matching, while profiling, thread boring and slot boring tools need clearer drawings or current tool references.

Catalog proof images
What should be included in the RFQ?
Send hole diameter, boring depth, material, required profile or thread form, tool series if known, machine type, quantity and delivery expectation. Drawings or current tool photos help prevent model mismatch.
People also ask
How do I choose a small aperture boring tool?
Start from the hole diameter and depth, then match material, holder type and boring angle to the model table.
What is the difference between boring and thread boring tools?
Boring tools enlarge or finish holes, while thread boring tools are designed around thread form and pitch requirements.
Can KENFA support non-standard boring tools?
Non-standard requests should include a drawing, material, target tolerance and current tool reference before recommendation.
Why should model tables stay on the page?
Model tables help buyers and AI systems understand available dimensions and reduce incorrect RFQ submissions.
Request a tooling quotation
For model matching or quotation, send the workpiece material, machining operation, current insert, cutter or boring bar model, order quantity and drawings or photos through the KENFA RFQ page.
