Cutting Tool Quality Control

Cutting tool inspection starts with the dimensions and cutting features that matter to your job: tool fit, cutting profile and the limits on the drawing.

MSU uses a ZOLLER G3 measurement system. For your order, identify the critical characteristics, tolerances and records required so the inspection can address your purchasing and machining needs.

Send the tool reference and mark the dimensions or records you need.

Discuss Inspection Needs

Define the Dimensions That Matter

A cutting diameter, insert seat and holder connection serve different purposes. Select the measurements that establish tool size, fit and cutting geometry.

Size and Mounting

Dimensions that determine the tool envelope and connection.

Dimensions to identify
For shank tools: cutting and shank diameters, cutting length and overall length. For inserts: thickness and seating dimensions.
Fit to the assembly
Identify the holder or cutter reference and its connection. Check the tool drawing against the mounting requirements.

Cutting Geometry and Edge

Features that define the cutting profile and contact with the part.

Features to identify
Specify the nose or corner radius, profile, chamfer, hone or other cutting-edge feature relevant to the tool.
Limits to apply
Mark the nominal value, tolerance and measurement location on the drawing. State any edge-condition or appearance criteria.

List any sampling and measurement-record requirements before ordering so the checks can be agreed for the tool.

Tool Measurement and Test Conditions

A measurement result needs a defined feature and test condition. Keep the tool reference, measurement position and tolerance together.

MSU uses ZOLLER G3 equipment for tool measurement. Specify the dimension or geometric feature to be checked and the tolerance that applies.

For a runout requirement, identify the clamping arrangement, projection and measurement position. For a profile or radius, mark the feature and the nominal geometry on the drawing.

If your incoming-inspection process requires a particular measurement method or equipment record, include it with the request. Agree the method before comparing results from different setups.

Set the inspection points, tolerances and records before placing the order.

Plan the Tool Checks

Agree Checks Before Production

Use the approved tool drawing or agreed product specification to define what will be measured and how the result will be accepted.

Drawing and revision

Use the same approved revision for the tool dimensions, tolerances and inspection request. For a standard tool, retain the complete code and the agreed specification.

Features and tolerances

Identify which dimensions control fit or the finished feature. Specify the nominal value, tolerance and measurement location for each critical characteristic.

Checks and records

State any in-process or final measurements, sampling quantities and reports needed with the order. The quotation should identify the agreed checks and records.

Reporting a received-tool issue

Notify MSU within 30 days of receipt. Include the order and tool references, measurements, photographs and any batch marking. See Ordering and Delivery for the issue-reporting terms.

Check the purchasing terms and information required for an issue after delivery.

Compare Measurements After Delivery

If a received tool differs from the expected dimensions or result, start with the exact reference and the measurement that raised the question.

Compare the received tool with the agreed code or drawing revision. Record the nominal dimension, measured value and where and how the measurement was taken.

For a fit problem, include the holder or cutter model and photographs of the connection. For wear, chipping or surface marks, add the workpiece and cutting conditions.

  • Order and complete tool reference
  • Drawing revision or agreed specification
  • Measured value and measurement position
  • Holder or machine setup when relevant
  • Photos, labels and a description of the issue

Keep the tool and its packaging or label while the issue is investigated. Matching the tool reference and measurement setup helps distinguish a dimensional concern from an assembly or machining problem.

If you need to identify the tool type first, use All Products.

Find the Tool Type

Request the Records You Need

A product drawing gives nominal specifications. A dimensional report records measurements. Identify which information your purchasing process needs.

State the exact tool or project and the document format needed. Confirm the measured features and report content with the order.

Product drawings and size tables

Use Downloads to find model codes, nominal dimensions and tool geometry.

Custom-tool dimensional report

A dimensional report can be discussed for a custom-tool project. Mark the characteristics and tolerances to include before the drawing is approved.

Inspection results for an order

Request the agreed measurements with the complete tool and order reference. Specify which features and quantities the record should cover.

Measurement and identification details

If your acceptance process requires equipment information, batch identification or a particular report format, list those items before ordering. MSU will confirm what can be provided.

Quality Control Questions

What measurement equipment does MSU use?

MSU uses a ZOLLER G3 measurement system. For results on a specific tool, identify the dimensions, tolerances and measurement record you need.

What should I specify for a tool inspection?

Provide the full tool code or drawing revision and mark the critical features, nominal values and tolerances. Include measurement positions or clamping conditions where they affect the result, plus any sampling and reporting requirements.

Can I request a dimensional report?

Yes. A dimensional report can be discussed for an applicable custom-tool project. Agree the measured characteristics, tolerances, quantity and report format before ordering.

How should I report a quality issue?

Notify MSU within 30 days of receipt. Include the order and tool references, the measured result and setup, and clear photos or video. Keep any batch marking and packaging. For a machining issue, also include the workpiece and cutting conditions so the cause can be investigated.
