Pramet TNMG Lathe Insert, 93° Approach, 16.5mm Length - TNMG 160412E-R:T9335

This is a double-sided negative turning insert designed for precision machining. It features a triangular shape with an inscribed circle diametre of 9.525mm and a thickness of 4.76mm. This insert is coated with MT-CVD for enhanced performance and durability. It is suitable for a wide range of applications, including fine to heavy machining of steels.

Features & Benefits

• Insert can be used on both sides, maximizing its lifespan
• The insert’s geometry allows for efficient material removal and smooth cutting
• The coated carbide material ensures excellent wear resistance and extended tool life
• The chip-breaker design with rounded edges minimises chip buildup and enhances chip evacuation
• Whether you’re working with mild steels or tougher materials, this insert delivers consistent results

Applications

• Ideal for machining steels with alloy content up to 10% and hardness below 45HRC
• Suitable for castings of iron and carbon alloys with more than 2% carbon content
• Can handle engineering metals with a hardness greater than 45HRC

Turning Inserts

Breakdown of ISO Reference

Higher Number = Tougher / Resistant to Impact
Lower Number = Harder / Wear Resistant

TU5525 the New Universal Turning Grade

TU5525 is a truly universal tuning grade suitable for cutting Steel, Stainless Steel, Cast Iron and heat resistant Aaloys. There is no need to hold stock of a multitude of grades reducing the cost of inventory and time wasted changing inserts. One insert for almost all applications.

TP2135 a Tough Impact Resistant Grade

If insert breakage or chipping of the cutting edge is a problem TP2135 may be the answer. Some application do not offer the cutting edge a constant cutting surface whether from a non round part or holes in the part this constant impact on the cutting edge can lead to insert failing. TP2135 is designed to take higher impact loads giving a more secure cutting edge, suitable for cutting steel, stainless steel and heat resistant alloys.
