GC4205
Sandvik Coromant completes its New Insert Generation with the introduction of GC4205, the first choice new insert grade for steel turning at high speeds and high metal removal rates under stable conditions. The new grade has an extended performance range, from roughing to medium and semi-finishing, and withstands operations where high cutting temperatures are generated.
GC4215
A new steel turning grade from Sandvik Coromant, GC4215 delivers higher performance machining results across a wide steel application area and enables increased cutting data in wet and dry conditions. Advanced grade technology has allowed GC4215 to improve productivity without losing security in the P15 area for roughing to finishing and at continuous to light intermittent cuts in P10 to P20 applications. It is the latest addition to the New Insert Generation from Sandvik Coromant.
GC4225
GC4225 from Sandvik Coromant represents the next generation of P25 grades to enhance machining performance in the general steel turning area. GC4225 has an improved capacity to adapt to variations in workpiece material and operational demands towards the tougher end of applications, thus providing more versatility. The new black and yellow grade provides a new potential for increasing productivity through higher cutting data, backed up by improved reliability. |

Improved levels of performance across the board from these two steel turning stars
These steel grades complement each other perfectly sharing the same hard line approach to metal cutting. They are durable, versatile, predictable and secure and with their no compromising attitude you have the best solutions in steel turning.
GC4225 is the first choice from roughing to finishing, whether small part machining, bar peeling, or parting and grooving, it even makes light of heavy turning.
When GC4235 is for :
- deal for demanding difficult surfaces, interrupted cuts and lower speeds
- Even works well in stainless steels
- Secure enough to run in unmanned and automated production even in unstable conditions

Posimatic™ - Swiss Automatic
Stellram has a range of tools for use on Swiss Auto type lathes with small cross section shanks from 0.375” (10mm) square to 0.750” (20mm) square. Grades and geometries are available to handle the specific feeds and speeds associated with these machines.
Some other features of this program are:
- Nose radii starting at 0 for excellent surface finishes and sharp internal corners
- New –62 geometry and new PVD technology
- Equal shank and tool tip dimensions on all toolholders for programming ease
- Boring bars with standard coolant holes to aid in chip evacuation
- Part-off inserts from 1.6mm/0.063” to 3.0mm/.118” widths
- Integral shank cutoff and grooving holders for maximum rigidity
- Back turning holders and inserts for turning behind a shoulder eliminates additional operations
- Tungsten Carbide reinforced boring bars to eliminate chattering |

A new concept from Sandvik Coromant is set to provide significant performance benefits in profile machining; the CoroTurn TR® offers a more stable clamping and improved security via a robust T-rail interface between insert and holder.
Profiling operations place extreme pressures on the tool, and conventional clamping designs often leave the insert open movement during machining which reduces component tolerance and quality.
To combat this, the T-rail design uses horizontal and vertical rails to provide a stronger support for the insert in the tool holder to reduce insert movement, leading to the production of higher quality, closer tolerance components. Further stability can also be achieved via a long insert screw which reaches deep into the holder to clamp the insert firmly in place.
The two cutting edge design utilises optimized geometries and facilitates the requirements of good chip evacuation, needed to offer more continuous, uninterrupted machining.
The CoroTurn TR® is designed for turning operations using -V (35۫) and -D (55۫) style inserts and is well suited to medium to finishing applications and the operational demands of modern multi-task machining. |

Threading Systems
Kennametal offers two standard tooling systems to meet your threading application needs:
LT - Laydown Triangle Threading for fine-pitch threads
Top Notch Threading for superior performance in heavy-duty machining applications
LT - Laydown Triangle Threading
The solution of choice for general use and adjustable shim applications.
Top Notch Threading
The ideal solution for for heavy-duty applications. |

Partial Profile
Partial profile threading inserts are available in two types with thread angles of 60° and 55°.
- 60° TYPE (ISO and Unified)
- 55° TYPE (British Standard Whitworth)
The partial profile inserts cut without machining the crest of the thread. The same insert can be used for a range of different thread pitches. |
