Sandvik Coromant is now launching CoroMill 690, a long edge cutter for titanium milling, specifically suitable for aerospace components, such as the structural parts of airframes, wings and fuselages and landing gear. The amount of titanium in high strength complex components is increasing and with this anticipated demand there is a critical need for improving machining efficiency.
CoroMill 690 is a high productivity cutter, with cutting inserts with four cutting edges for economic 2-D profile operations and optimised chip flutes to reduce chip jamming. Every insert pocket has a threaded coolant hole prepared for a nozzle for high pressure coolant delivery to optimize chip evacuation. The chip evacuation is highly appreciated when face and shoulder milling in cavities, in pockets or in full slots.
First choice applications include circular interpolation from a pre-drilled hole; edging and contouring and repeated square shoulder milling. The iLock rigid interface keeps the inserts rigid for consistently accurate milling. Axial support prevents insert breakages on the bottom row and chip jamming on the second row.
The CoroMill 690 long edge cutter is designed for use with the Coromant Capto modular tool holder system for stability and shank clearance, essential when machining long overhangs and reaches. The cutter is available in diameters of 50 to 100 mm, with two insert styles and closer pitch on large diameters for profiling.
The cutting inserts come in grades GC1030 or GC2040 in SL geometry, optimised for edging in titanium.
Sandvik Coromant is now introducing two new sharp, tough insert grades, GC1125 for stainless steel applications and GC1515 for steel. Based on the latest developments in cemented carbide and coating technologies, these are to meet rising demand for sharp cutting edges with high edge-line integrity in light-turning machining.
The new grades are ideal for short engagements, machining of small parts, or when additional edge-toughness is needed. Typical applications are interrupt cut, machining into shoulder, or internal finishing.
GC1125 brings high edge sharpness for secure, burr-free machining of stainless steels and has the toughness needed for intermittent cuts. It is a strong performer in sticky materials and a good choice for vibration-free machining. The improved edge line strength and sharpness maintain good chip control, surface finish and tool life even at lower feed rates.
GC1515 for steel machining benefits from the unique combination of a wear resistant coating and a tough secure edge. This gives the ability to produce more components per cutting edge, while maintaining close tolerances, with a minimal number of off-set corrections.
GC1125 and GC1515 is a direct route to reliable and more predictable machining with cutting edges that ensure operational consistency and component quality for a longer time. These are benefits that give trouble free machining and a more profitability production.
Valenite LLC expands to its Penta family of milling cutters by introducing an inch version of the V560 heavy roughing milling cutter. Originally launched in metric diameters, the new V560 inch version allows operators to utilize the full potential of machine tools while securely performing heavy roughing operations in cast and forged steel, stainless steel, and cast iron. The V560 excels under difficult, full depth-of-cut machining conditions in forgings and beneath-casting scale increasing metal removal rates and production capacity while using less horsepower. With its double-sided Penta design, 10 indexes per insert, it is also a cost effective solution.
The V560 10mm depth-of-cut capability lets operators machine under the tough outer layer of forge or cast workpieces, reducing insert wear compared to smaller inserts. The inch version is part of Valenite’s spring product launch supporting the company’s dedicated efforts to expand and standardize its product offerings. V560 is ideal for the automotive, oil/gas, aerospace, power generation, off highway, marine, heavy equipment and general machining industries where heavy roughing operations are performed.
The V560 features Valenite’s patented ThruLok technology which only requires a single, large, insert retention screw that remains in the body for easier indexing. With just three turns of the insert retention screw while on the machine, there is no cool down period required before indexing, allowing for more machining uptime. The insert edges are also numbered for easy indexing. ThruLok technology secures the insert into the cutter pocket at an angle of 30 degrees. By rotating the insert down to its final location and tightening three revolutions, the insert seats firmly in the cutter.
CoroMill 360, the new 60 degree face mill from Sandvik Coromant combines high security and cost-effective performance for heavy-industry segments.
A robust cutter body in through-hardened steel provides strength for the most demanding operations, with wedge-clamped inserts housed in an exchangeable cassette system to maximize machining performance. The precise location of the cassettes against the cutter body ensures accurate cutting performance while quick-release inserts, which can be removed with one turn of the wedge screw, help to reduce tool change times and provide maximum flexibility.
The 4-edged inserts give a light-cutting performance and are available in 19 mm and 28 mm, with each size using the same cutter body to keep tool inventory to a minimum. They offer a maximum cutting depth of 18 mm at high feed per tooth to ensure a highly productive performance. Their wide parallel land design ensures a high surface finish quality unique for a heavy duty milling cutter.
CoroMill 360 is available in diameters from 160 – 500 mm in close and extra close pitch design, Arbor and CIS Arbor shank styles. Inserts come in high-performance, New Insert Generation grades for steel, stainless steel, cast iron and heat resistant super alloy machining.
Valenite LLC introduces a heavy duty, facing and profiling button-style mill to its milling product offering. Utilizing VP2003 round inserts with MicroForm technology, the V200 is ideal for hardened steels, heat resistant super alloys, titanium, and die-and-mold applications. With the more feed in pocket roughing, depth of cut up to 0.400” and round inserts with seven degree clearance, the V200 excels under heavy roughing applications, and is resistant to breakage and chip re-cutting. The V200 is also capable of more feed and improved tool life even in interrupted cuts.
Positive insert geometries with negative rake angles offer the best combination for strength and productivity and V200 is available with eight to 12 indexes (depending on depth of cut) for precise insert positioning. The V200 was developed specifically for die-and-mold, aerospace and general engineering applications, and excels in ramping, as well as helical interpolation of pockets and holes.
Available with VP2003 with Microform, the V200 offers versatility on a variety of workpiece materials. MicroForm technology is a special carbide grade technology of powder preparation and sintering, providing the capability to direct-press inserts with a superior uniform micrograin structure. This extremely hard carbide grade with an exceptionally homogenous grain structure is free of inclusions and cubic carbides, a potential source of crack propagation which leads to chipping. It maintains sharp edge conditions in work hardening materials.
The V200 is also available in high performance grades VP5020, VP5040, VP1020 and VP5135 to address steel, stainless steel and cast iron applications.

ISCAR’s SUMOCHAM drill family is the next evolution of the very successful CHAMDRILL and CHAMDRILLJET families. The new family has similar features, with improved head and pocket design, no setup time, Fast Metal Removal and economical indexing.
The SUMOCHAM comprises a revolutionary clamping system that enables improved productivity output rates, while enabling more insert indexes. The shank itself is designed with twisted nozzles and exhibits a durable and stably constructed body.
The indexable heads are available in four different standard geometries, designed for drilling steel, exotic materials, cast iron or aluminum.
The unique pocket design of the SUMOCHAM takes good advantage of the cutting forces, which are mechanically exerted upon the tool. These forces are then converted into gripping forces that are used for tightening the insert towards the back of the pocket. In that sense, the more cutting forces applied, the better gripping forces obtained.
In addition, the clamping forces around the connection area generate little strain, preventing any potential plastic deformation and by that providing at least triple the amount of head indexes.
The most important attribute of the new clamping design is therefore a very substantial increase in productivity.
All of these features provide the most productive and most profitable solution for the hole making industry.
Sandvik Coromant has released their latest high-performance sharp-edge grade, GC1115. It is designed to give secure and reliable performance in all applications from aerospace to general engineering.
A good balance of toughness and wear resistance makes GC1115 an effective choice for more unstable conditions, especially where predictable production with fewer unplanned stoppages is always a high priority. It is versatile enough to complete an entire component and increase active machining time due to a unique PVD coating which maintains sharp edges over a longer time in cut, while optimized micro-geometries ensure high component precision at low cutting forces.
The new grade can be used for finishing to medium machining in stainless steel and medium to roughing in heat resistant super alloys and titanium. It is available in a wide selection of positive and negative basic-shape inserts and the full -M, -G and -E tolerance range for different insert edge sharpness,as well as CoroCut® angled inserts for improved access in aerospace applications.
GC1115 is part of the PVD chain within the ‘green-light production’ message from Sandvik Coromant – a group of insert grades with improved wear resistance, giving closer tolerances and higher security. Together with GC1125 and GC1105, it offers lower costs and true, undisturbed machining performance.
