Custom Insert Blanks

Customized cemented carbide insert blanks are preformed to create a specific cutting geometry to meet your tool requirements.

Metal cutting custom insert blanks are preformed shapes or forms made of hard and wear-resistant tungsten carbide. Insert blanks are further processed into finished tools by the tool maker to be used as tools for threading, parting, grooving, drilling, reaming, and milling applications. Insert blanks are provided in a near-net-shape form customized to meet the specific cutting geometries of the customer's desired tool applications. Near-net-shape insert blanks minimize the need for additional shaping and grinding by the customer.

Insert blanks are typically machined to the desired shape and size of the tool by using computer-controlled milling machines. The finished tools can be coated using chemical vapor deposition (CVD), physcial vapor deposition (PVD), or other diamond coatings to enhance the performance and extend the tool life. Hyperion offers cemented carbide grades for insert blanks that are qualified with various coating suppliers.

At Hyperion Materials & Technologies, we can design and manufacture a range of cemented carbide blanks tailored to each customer's unique design to improve tool productivity and throughput. We offer three finishing options:

  • As-sintered

  • Top face and bottom face (T&B) ground

  • T&B and periphery ground.

Hyperion Code: n/a

Description: Cemented carbide insert blanks are the basic building blocks of cemented carbide cutting tools, made of a mixture of tungsten carbide (WC) and cobalt (Co), which are sintered together at high temperatures. The tungsten carbide provides hardness and wear resistance, while the cobalt acts as a binder and gives the blanks their toughness. Hyperion Materials & Technologies provides preformed cemented carbide insert blanks tailored to each customer’s unique design. We offer three finishing options: as-sintered, top face and bottom face (T&B) ground, and T&B and periphery ground.
