Cutting tools
Ingersoll has developed Evo-Tec, the next generation in the company’s MAXline family. According to the company, the strength and stability of these cutting tools improves chip control. As well, longer tool life results from a larger insert seating surface plus a stronger cutting edge.
The multi-purpose insert geometry works well in virtually all types of material and features a primary land that improves cutting edge strength. The four-edged Evo-Tec inserts offer an economical advantage over the two-edged competition, according to Ingersoll, and a DOC capability of up to .420 in. Corner radii are available in .031 in., .062 in., .093 in., and .125 in. Cutter diameters range from 1.250 in. to 4.00 in. and coolant/air through the tool is available. Medium and High Density versions expand application options.

Boring bars
Engineered specifically for extended-length boring applications (from 4:1 up to 6:1 diameter-to-length ratio), new heavy metal boring bars from
Kennametal Inc. function well in finishing and medium machining ID turning, grooving and threading tasks. A hybrid of heavy metal construction with brazed steel heads, the company says that these boring bars are more rigid for greater extended-length capability compared to steel bars and are less expensive than carbide boring bars. The Kennametal design also supports the insert better than heavy metal alone, reducing
failure possibilities while in use.
The new bars are available in a variety of sizes, including 8, 10, 12, 16, and 20 mm and 3/8, 1/2, 5/8, 3/4, and 1 in.

Cutting tools/threading
Sandvik Coromant has introduced the CoroThread 266, a new family of rigid, high precision threading tools that the company says provide increased productivity and stability. The new tool is available in 0.5 in. and 0.625 in. insert sizes.

The CoroThread 266 achieves stability through the iLock insert locking system. With this new design, an insert contains a slot for each of its three indexable cutting edges. When locked into place, these slots correspond to a raised guide rail on the actual tool, providing a more stable interface, claims the company. The iLock system simplifies tool set-ups, eliminates potential insert movement during machining, and provides repeatability with high levels of accuracy. Additionally, iLock disperses cutting forces with no pressure points, reducing the strain on both tool and insert to provide longer tool life.

An extremely stable tool, the CoroThread 266 reduces machining vibration to provide superior surface finishes. The E-tolerance of the
system is 0.0004 in. axially and 0.002 in. radially, minimizing the effects of changing cutting edges to ensure maximum product consistency.
