Buying Guide
Thinbit parting inserts are essential tools for precision cutting. They reduce waste and ensure clean cuts in various materials.
Choosing the best Thinbit parting insert depends on your needs. Here’s what to consider:
-
Material Compatibility:
Pick inserts designed for your material. For steel, cast iron, or stainless steel, choose DURA-MAX 2000 carbide. For non-ferrous alloys, aluminium, or plastic, go for uncoated carbide or DURA-MAX 5000. -
Cut Type:
Decide if you need interrupted cuts or continuous cuts. Some inserts work best without interruptions, while others handle interruptions well. -
Width and Size:
Narrow widths minimize waste and part deflection. Check the insert’s width to match your project’s needs, especially for tight spaces or small parts. -
Toolholder Compatibility:
Ensure the insert fits your toolholder. Large series and Small series toolholders are common options. -
Coating:
TiN-coated inserts offer extra durability for tough materials like steel. Uncoated carbide works well for softer materials. -
Application:
Consider your project. For precious metals or thin tubing, choose inserts with precise cutting capabilities. For solid stock or tubing walls, check the insert’s size limits.
With these factors in mind, you’ll find the perfect Thinbit parting insert for your cutting tasks.
