Sumitomo 14EK326 Milling Insert DL1000 Solid Carbide

Product Description

The SUMITOMO 14EK326 is a solid carbide coated milling insert designed for precision material removal in metalcutting applications. It features a parallelogram insert shape with an AXET style and carries the DL1000 manufacturer grade, which uses a diamond-like carbon (DLC) coating process suited for non-ferrous metal cutting. The insert measures 0.472 inches in length, 0.260 inches in width, and 0.138 inches in thickness, with an 11-degree relief angle and a corner radius of 0.008 inches. An effective cutting edge length of 12.00 mm supports consistent chip formation and surface finish on non-ferrous workpieces.

This insert is intended for use in milling operations on non-ferrous metals such as aluminum and copper alloys. It is compatible with the WEX2000 cutter series and is sized to the 1235 insert size code (full insert size designation 123502). The DLC coating reduces built-up edge and friction when machining soft, gummy materials, making it a practical choice for high-speed finish milling passes. It is sold individually with a minimum order quantity of 10 units and is a direct replacement or web-sourced insert for supported cutter bodies.

• Corner radius of 0.008 inches supports fine surface finish requirements
• Effective cutting edge length of 12.00 mm for consistent engagement
• Solid carbide substrate provides rigidity and wear resistance at elevated cutting speeds

Compatibility

Compatible with the WEX2000 cutter series. Insert size code 1235 (full designation 123502) with a thickness range of 0.125 to 0.150 inches and a length range of 0.450 to 0.500 inches.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the spindle fully stopped and machine power locked out per shop safety procedures. Use the appropriate torque wrench and insert clamp hardware specified by the cutter body manufacturer — do not exceed the clamping torque listed in the cutter body documentation. Inspect the insert seat and clamping surfaces for chips or debris before seating the insert to prevent insert rocking or premature breakage.
