Introduction
The Y Pro series by Tungaloy is a new line of indexable inserts designed for profiling and taper cutting, featuring a 25° corner angle for machining in restricted areas.

Specifications
The series is compatible with both internal and external machining toolholders, supporting operations like taper cutting, undercutting, and "V" grooving. It can be mounted on conventional toolholders, reducing the need for special tools and lowering production costs.

Technical Information
For taper cutting, a depth of cut of 1.0 mm and a feed rate of 0.2 mm/rev are recommended. Chip thickness increases by 1.5 times, requiring a feed reduction to 2/3 of the recommended rate. The series offers improved chip control with high chipbreaker walls and hemispherical protrusions.

Toolholder Compatibility
The inserts can be used with existing 35° toolholders, but attention is needed for the undercut shape of the insert pocket. Inserts with a 0.4 corner radius cannot be mounted on toolholders with undercuts on only one side.

Cutting Conditions
Recommended cutting conditions vary by chipbreaker type and corner radius. For carbon steel (C45), a cutting speed of 200 m/min is suggested. The series supports both positive and negative inserts with specific guidelines for feed rates and chip control.

Product Range
The series includes various insert types and toolholders for both internal and external use, designed for smaller bore diameters and expanded machining capabilities.

Conclusion
The Y Pro series offers versatility, cost reduction, and improved performance in challenging conditions.

Specifications
Details on tool holders and inserts focus on S-type holders with positive, screw-on types, including edge styles H, I, Q, and U. Item codes, dimensions, replacement parts, corner radius, stock availability, clamping screws, wrenches, and recommended torque values are listed.

Procedures
Machining examples demonstrate the use of Tungaloy toolholders and inserts in materials like 20CrMoVTiB-4 and 41CrAlMo7, outlining cutting speeds, depth of cut, feed rates, and coolant usage.

Norms and Certifications
ISO 9001 and ISO 14001 certifications indicate compliance with quality and environmental management standards.

Recommendations
The series is recommended for improved chip control and reduced machining processes, with benefits of switching to ZF-type inserts for better productivity and tool life, noting a 50% increase in tool life and 30% reduction in tool costs.

Results and Benefits
The series offers improved chip evacuation and control, superior surface finish, and significant cost reductions, allowing for a drastic improvement in machining by reducing the number of processes and tools required.
