Duracarb Carbide Inserts & Milling Blades

Duracarb Carbide Inserts & Milling Blades — APMT • TNMG • RPMT

Duracarb offers a wide selection of carbide inserts for milling and turning: APMT, TNMG, RPMT and related chipforms / grades (examples: DP5320, DC9025). These inserts suit steel, stainless, cast iron and non-ferrous machining when matched with the right grade and cutterbody. 

Why choose Duracarb inserts?

Cost-effective performance

Duracarb balances price and life for common machining tasks — ideal where high-value replacement insert budgets are limited.

Common compatible geometries

APMT, TNMG, RPMT and other widely-used geometries that fit common cutter bodies and toolholders.

Multiple grades available

Grades like DP5320 and DC9025 (example listings) target stainless, hardened steels and general-purpose cutting—select grade to match material and cut.

Popular Duracarb Models & Applications

Model / Grade Geometry Typical Application Notes
APMT1604 PDER (DP5320) APMT / 16×16 / R0.8 Face milling / finishing on stainless and alloy steel Good balance of wear resistance and toughness. Example SKU in market listings. 
TNMG160404 (DC9025) TNMG / turning External turning and general machining of steel Listed widely by Chinese suppliers — economical option. 
RPMC / RPMT series Indexable milling Slotting and cutterbody-based milling Available in multiple chipforms; confirm chipbreaker for material.

Technical Data & Compatibility

Always match insert geometry (APMT / TNMG / RPMT), thickness, corner radius and grade to your cutterbody and machining parameters. Below is a quick reference — confirm exact dimensions from your supplier datasheet before ordering.

Parameter Example
Insert thickness (T) APMT1604 ≈ 4.76 mm (confirm with datasheet)
Corner radius (r) R0.4, R0.8 etc. — choose by finish requirement
Grade examples DP5320 (general/SS), DC9025 (wear-resistant), others depending on supplier

How to select the right Duracarb insert

  1. Identify the geometry that matches your tool/cutter (APMT, TNMG, RPMT).
  2. Choose the corner radius and chipbreaker for your desired surface finish and depth of cut.
  3. Match grade to material: tougher grades for interrupted cuts, wear-resistant grades for abrasive materials.
  4. Test recommended cutting data on a sample job and optimize speeds/feeds for life & finish.

Notes: Product model examples and grade names (DP5320, DC9025) are based on public supplier listings. Verify exact grade and geometry with your supplier datasheet before production use
