🏭 APKT Carbide Inserts – Precision Milling Performance for Every Application
At CNC Tools Depot, we offer the world’s largest collection of APKT Carbide Inserts – engineered for superior performance, longer tool life, and unmatched precision in milling operations. Whether you’re machining steel, stainless steel, cast iron, or non-ferrous metals, APKT inserts deliver exceptional cutting stability and surface finish.
🔧 What Are APKT Carbide Inserts?
APKT inserts are a positive, single-sided, 90° shoulder milling insert widely used in face milling, shoulder milling, and pocketing applications. They are designed for high-feed and high-efficiency milling operations, featuring a two-edged design with an optimized cutting geometry that reduces cutting forces and heat generation.
Made from premium tungsten carbide grades with PVD or CVD coatings, APKT inserts provide excellent resistance against wear, built-up edges, and thermal deformation — ensuring consistent accuracy even in demanding machining conditions.

Frequently Asked Questions
APKT is a standardized insert code defined by ISO. It indicates the shape, clearance angle, tolerance, and other geometrical features of the insert.
Yes, polished and sharp-edged APKT inserts (like APKT1604PDFR-AL) are ideal for aluminum and non-ferrous metals.
APKT inserts are compatible with APKT-type milling cutters such as end mills, face mills, and indexable milling cutters designed for positive rake inserts.
No, carbide inserts are disposable. Once worn, they should be replaced to maintain precision and safety.
PVD TiAlN or TiCN coatings are best for stainless steel due to their high heat resistance and lubricity.
Typically, APKT inserts have two usable cutting edges per insert.
The number refers to insert size — APKT1604 is larger (for higher depth of cut), while APKT1003 is smaller (for finer operations).
Yes, most APKT inserts follow ISO standards and are interchangeable among major brands, provided the toolholder matches.
It depends on material, insert grade, and coating. Generally, medium speed and feed settings are ideal for initial setup.
Yes, APKT inserts are suitable for both CNC and conventional milling machines.
