Beyond Blast is the company’s method to deliver coolant through the insert itself.

Kennametal’s Beyond is a line of high performance turning products. Because of higher metal removal rates and extended tool life, these products are designed to push productivity 30-percent higher or more for a variety of metalworking users. The turning products offer a line of 11 grades applicable to steel, stainless steel and cast-iron turning applications.

According to Kennametal, higher cutting speeds, longer tool life and increased productivity when machining stainless steels are what users can expect from the upgraded line of KC9225 inserts, part of the Kenna Perfect turning system from Kennametal Inc. Enhanced post-coat finishing processes are designed to reduce chip hammering and built-up edge conditions, extending tool life and preventing insert damage, particularly in applications demanding continuous to lightly interrupted cuts at high cutting speeds.

Kennametal's A4 groove and turn inserts for high-productivity grooving, face grooving and cutoff across a variety of materials, are now available in narrow groove widths of 1. 5, 2 and 2. 5 mm, bringing the range of A4 sizes from 1.

As a cost-saving measure and to comply with environmental considerations, many shops turn to recycling programs for scrap and worn tooling. With increasing consumption of non-renewable raw materials and to help counteract the effects of high carbide prices, some manufacturers are providing recycling programs to help companies increase productivity and efficiency.

Kennametal's A4 groove and turn inserts, made of KYON 3500, enable high-productivity machining of gray cast iron designed for high speed grooving applications. The grade is an advanced silicon nitride ceramic grade developed by Kennametal. In tests, its higher toughness and the advanced insert design resulted in higher feed rates.

Kennametal's turning grade KC9105 enables high productivity machining of steels by allowing up to 40 percent higher cutting speeds without sacrificing toughness. There inserts are engineered for finish turning to medium machining of all steel workpieces including carbon, alloy and tool steels as well as ferritic, martensitic and precipitation hardened stainless steels. Products that can take advantage of this insert include transmission components, axles and gears in automotive and transportation markets and shafts, bearings and pump housings in general engineering applications.

With its program for driven tools with VDI40 and VDI50 toolholders, Kennametal is meeting the market's growing need for complete machining on lathes, also. This program allows both drilling and milling to be performed on lathes with driven tool capability. The VDI holder drive conforms to DIN 5480 and DIN 5482.

Turning grades KC5010 and KC 5025 are primarily applied in finish machining and general-purpose machining of high-temperature alloys, stainless and alloy steels. They also can be used in cast iron and nonferrous applications requiring keen cutting edges. The company is optimizing the aluminum content in the advanced PVD TiAIN coating, which increases resistance to wear at the cutting edge.

- Features the Kenna Universal series of turning tools, which represents a small number of grades that work across a variety of ferrous, non-ferrous, high-temperature and hardened materials and are used for turning, boring, grooving, threading and cutoff- Includes the A4 Groove & Turn system as well as new sections devoted to classic products and Kenclamp toolholders and boring bars .

Three turning guides provide application information as well as a catalog of turning inserts and grades. The guides include book covering steel materials, a guide covering cast iron materials and a guide covering high-temperature alloys. .

Mill 1, a line of indexable insert end mills that can increase productivity, offered in diameters from 0. 97" to 8", was designed specifically to deliver high-performance pocketing and hole drilling. It also is said to offer at least a 30 percent increase in maximum rotational speed, enabling productivity gains when cutting softer materials, such as aluminum and plastics.

The Mill 1 line of end mills is offered in diameters from 0. 97" to 8". The line was designed to ramp aggressively so it delivers pocketing and hole drilling performance, the company says.

The productivity of new Swiss-style machines has increased in recent years as faster spindles, more rigid bases and improved controls have made it possible to dramatically increase metal removal rate. But while cycle times have been substantially reduced, the time required to change cutting tools has stayed largely the same.

Close confines found in Swiss-type machines make tool changes time consuming. A new quick-change system is helping reduce this problem.

The new A2 cutoff tooling provides an insert locking mechanism that enables heavier cuts and improves surface finish while providing longer toolholder and insert life. The new line of cutoff tooling also offers an insert stop design that automatically increases clamping forces as cutting forces increase, further increasing the amount of insert holding power. The A2 clamping system is designed to mate with inserts with V-prisms on both their top and bottom surfaces, providing positive locking against movement in any direction and making it possible to use higher locking forces.

It's increasingly rare that shops can use "set it" and "forget it" tooling schemes for screw machine production runs. Today's schedules require more frequent changeover. Quick-change cutting tools, coupled with more advanced tool materials, are helping shops remain productive and competitive. 

The KennaPERFECT system of metalcutting inserts for turning operations combine high performance grades and application-focused geometries to deliver maximum productivity in machining specific workpiece materials. The system includes new, simplified grade and geometry naming methods. The inserts also feature user-fri
