Technical resource / Selection & RFQ
From hole requirements
to a clearer RFQ
Define the hole, evaluate the tooling route and prepare a clear technical brief before requesting custom tools.
For cutting tool distributors, OEM/ODM buyers and engineering procurement teams serving European and US markets.

What this guide helps you decide
A tool request needs more than a nominal diameter. This guide connects application inputs with selection, inspection and quotation decisions. It does not replace a project-specific engineering review.
Select the right starting route
Separate drilling from bore finishing, identify the material and define the features that affect a PCD reamer or solid carbide drill concept.
Agree how success is measured
Distinguish tool inspection from workpiece acceptance. Prepare a trial record that preserves conditions, individual results and limitations.
Send a clearer RFQ
Give the supplier the drawing revision, machine context, acceptance requirements and commercial scope needed to evaluate the project.

Evidence comes before performance claims. The guide contains no verified XRZ customer case. Its cost calculation is explicitly illustrative, not a production result or price quotation. It offers no universal speed, feed, tolerance, surface-finish or tool-life promise.
Three fillable worksheets
Complete the fields in a compatible PDF reader, save a copy and reopen it to check your entries. The worksheets do not upload data or calculate results automatically.
Application Data Sheet
Capture the workpiece, hole, machine, coolant and current issue. Attach the controlled drawing rather than reproducing every dimension.
Sample Validation Record
Summarize the trial, acceptance criteria, measured results and next action. Keep the raw measurement log as supporting evidence.
Before-and-After Comparison
Compare options using consistent conditions, units, accepted-hole counts and cost boundaries. Do not count the same expense twice.
Useful for your route to market
Distributors: collect consistent end-user inputs and define who coordinates the trial and technical response.
OEM/ODM buyers: identify drawing control, review gates, branding scope and repeat-order requirements.
Engineering procurement: connect the quotation to acceptance criteria, application constraints and evidence requirements.

Before you use the guide
Does the guide recommend a universal cutting speed or feed?
No. Starting parameters must be selected for the exact tool, material, machine and cooling conditions, then validated under an agreed trial plan.
Can I use the worksheets without disclosing my customer?
Use a project reference where appropriate and remove information you are not permitted to share. Anonymization alone does not override a confidentiality agreement. Agree the transfer route before sending restricted drawings.
Is the worked cost example an XRZ case study?
No. It is an invented example showing the calculation method and why a shorter cycle does not automatically mean lower cost per acceptable hole.
Who wrote and reviewed this version?
Author: Kevin Zeng, CEO. Engineering reviewer: Jiack Liu, Engineering Director. Technical review and publication were approved by XRZ on 28 August 2026. Editorial preparation was AI-assisted.
Can I reference this guide from a technical article?
Yes. Reference the guide title, V1.0 and 28 August 2026, and link to this resource page. The guide explains selection and validation methods; it is not evidence of a specific XRZ performance result. General technical sources are listed inside the PDF.
Bring your drawing into the discussion
Judge the tooling route by Cost per Good Part / Cost per Accepted Hole — not tool price alone. Share the material, bore requirements, machine conditions and current problem. Identify any missing information instead of guessing values.
