Carbide Turning Insert PAFANA TNMG 160408 EL BP30A

PAFANA TNMG 160408 EL BP30A is a TNMG-series carbide turning insert designed for general metal turning operations. The TNMG 160408 format denotes a standard triangular negative insert with a 16 mm inscribed circle and geometry suited to common turning, facing and light to medium roughing tasks. The EL edge/relief style and BP30A grade/coating combination provide a balance of wear resistance and toughness for a range of steel machining applications when used in compatible TNMG toolholders.

Advantages

This carbide insert offers consistent cutting performance across a variety of steel types thanks to its BP30A grade and protective coating. The TNMG 160408 form factor ensures compatibility with widely used TNMG toolholders, enabling quick insert changes and predictable tool setup. The EL edge style improves edge strength for interrupted cuts and reduced chipping risk during medium-depth cuts, while the carbide substrate maintains wear resistance for longer tool life compared with uncoated grades.

Suitable for

• General turning of carbon and alloy steels
• Facing operations on steel components
• Light to medium roughing and semi-finishing
• Operations with intermittent cutting where edge strength is required

Key specifications

• Insert type: TNMG triangular negative insert
• Size designation: 160408 (standard TNMG geometry)
• Edge/relief style: EL
• Carbide grade/coating: BP30A
• Usage range: suitable for steel turning, light to medium roughing and facing
• Compatibility: designed for TNMG-compatible toolholders

How to use

Install the TNMG 160408 insert into a compatible TNMG toolholder following the toolholder manufacturer's tightening and seating instructions. Select cutting parameters (cutting speed, feed and depth of cut) appropriate for the steel grade and the BP30A grade's recommended range. Begin with conservative settings and adjust incrementally to optimize surface finish and tool life. Inspect the insert edge regularly for wear or chipping and replace the insert when wear compromises dimensional accuracy or surface quality.

Usage recommendations

Use coolant or appropriate cutting fluids when machining alloyed steels at higher cutting speeds to extend insert life. For intermittent cuts or work with hard inclusions, reduce feed or depth of cut to minimize edge chipping. Store inserts in a dry, clean environment and handle them carefully to avoid damaging cutting edges before installation.
