Aluminum alloys
Include alloy designation, silicon content, finishing allowance, required roughness and burr-control requirements.
Copper, graphite & composites
Identify the exact material, abrasiveness, fillers and interruption level before deciding on grade and edge geometry.
Holder & edge compatibility
Confirm the full insert code, seat and clamp. PCD tip layout, LE and edge preparation must match the operation.
Conventional PCD is generally not selected for steel or cast iron cutting. Mixed ferrous/non-ferrous workpieces need specific review.
View the PCD technical catalog →Questions about TEGN PCD inserts
Will this insert fit my current holder?
Confirm the full ISO code, seat, clearance and clamp arrangement. The family name alone does not confirm compatibility.
How do I choose a PCD grade?
Provide the exact material, aluminum silicon content where relevant, machining operation, required finish and cutting conditions. Select “Please recommend” if unsure.
What does LE mean in this table?
LE is the catalog cutting-edge reference length. Confirm the actual PCD segment layout and usable edge against the product drawing.
Are the listed sizes available in every grade?
These are catalog reference specifications. Confirm the model, grade, quantity and drawing for supply and lead-time information.
Can PCD inserts machine steel?
Conventional PCD is generally not suitable for steel and cast iron cutting. Ask for a separate evaluation of any bimetallic or mixed-material operation.
Can I send a custom drawing?
Yes. Send dimensions, PCD segment requirements, edge preparation and application details for a feasibility review.
