Cutting tools
Nominal geometry, size comparisons and documented product examples.
Look up an insert designation →Identify an insert from measurements →What do you need to find?
Engineering reference: thread charts, tap drill sizes, materials, insert codes, tolerances & calculators
Find thread sizes, tap drills, turning insert dimensions and material grades. Check tolerances and surface roughness, or calculate from known inputs.
Start with your task
01 / LOOK UP
Find a specification
Start with a marking or measurements.
Choose a reference ↓ 02 / COMPARECompare dimensions
See what changes between nearby sizes.
Choose a comparison ↓ 03 / CALCULATECalculate a parameter
Use known inputs, with units and assumptions.
Open calculators → 04 / UNDERSTANDRead a marking
Decode a tool, thread or surface requirement.

Threads & tapping
Find the specification before choosing the tapping drill.
Look up a thread size →Identify an unknown thread →Find a tapping drill →Materials
Look up a grade, then confirm its material condition and source.
Find a material grade →Compare grades and states →Read a material callout →Tolerances & finishes
Read drawing requirements, compare size limits and calculate with known conditions.
Explore tolerances & finishes →What does Ra 1.6 µm mean? →Convert µm and µin →Compare the specifications and conditions
Read a marking
Have the inputs already? Calculate turning RPM and feed →
Engineering calculators
Calculate from known inputs, with units and stated assumptions.
Check the source, keep the conditions
Nominal dimensions, manufacturer data and calculated results have different scopes. Each reference keeps those boundaries visible.
