Buying Guide

Looking for the best L Series parting inserts? These precision tools are designed to revolutionize your machining tasks. Whether you’re cutting steel, cast iron, stainless steel, or non-ferrous alloys, the right insert makes all the difference.

Choosing the perfect L Series parting insert can upgrade your cutting game. Here’s what to consider to ensure you get the best performance and precision every time.

Material Compatibility:
Choose inserts based on the materials you work with. For steel, cast iron, and stainless steel, go for uncoated carbide inserts like the LPT085D2 or LGPT085D2. For non-ferrous alloys, aluminum, and plastic, opt for inserts like the LGPT045D5R or LGPT025D5R.
Cut Type:
Decide if you need inserts for interrupted cuts or continuous cuts. Interrupted cuts require durable inserts like the LPT115D2, while continuous cuts work well with inserts like the LGPT045D5.
Width and Precision:
Narrow widths reduce material waste and part deflection. Inserts like the LGPT062D5R are ideal for precious metals and thin-walled tubing, ensuring clean, precise cuts.
Toolholder Compatibility:
Ensure the insert fits your toolholder. Large series toolholders work with inserts like the LGPT045D2, while MGEHR/L & MGIVR/L toolholders pair with MGMN300-M grooving inserts.
Coating and Durability:
Uncoated carbide inserts offer clean cuts and durability. For longer tool life, consider PVD-coated inserts like the MGMN300-M, especially for tough materials.
Cutting Depth and Reach:
Check the insert’s ability to cut close to the collet face or shoulder. Inserts like the LPT085D2 cut within 1/16″, while others like the LGPT045D2 reach .062″.
Pack Size:
