envisions setting a new holding standard, eventually elimi- nating side Weldon holders altogether. The company has an ambitious plan to roll out its holders and license toolmakers to grind Safe-Lock grooves into its tools. Haimer is unique as a toolholder maker in that it doesn’t also make cutting tools, so it has licensed the specifications on its spiral groove to an increasing number of cutting tool makers, such as Sandvik Coromant, Kennametal, Widia and Walter. “We’re just at the beginning of getting people to real- ize they should throw away the side locks once and for all,” Holden said. “They are wasting money.”
Haimer is offering Safe-Lock holders in its Power Shrink, Power Collet, Heavy Duty Collet and Heavy Duty Shrink Fit Chucks. In general, Safe-Lock can be added from tool diam- eter ½ up to 2" (12.7–50.1 mm).
Toolholding Innovations at Iscar
As part of a post-recession marketing campaign, cutting tool maker Iscar (Arlington, TX) at IMTS unveiled the biggest
new product onslaught in its 60-year history—a wide range of innovative and problem-solving products across its lineup. A highlight of those introductions is the Dove IQ Turn heavy-duty clamping toolholder system, part of a line of new products dubbed “Dove IQ” because of what Iscar calls a high-tech dovetail gripping system.

The Dove IQ Turn aims to solve several problems. One is to immobilize the cutting insert in the pocket, preventing it from lifting during high-stress turning. Also, the current method of using single-sided inserts and top-clamp holders has the dis- advantage of a fewer number of cutting edges and interrupted chip flow due to the obstruction of the top clamp. With Dove IQ Turn, Iscar has developed a dovetail pocket, which helps to prevent lifting, combined with a lever clamping system, which eliminates the need for a top clamp. “It’s a totally new design for heavy turning,” said Randy
Hudgins, national turning and threading product manager, Iscar. What’s more, he noted, it can also hold double-sided inserts: “So you can use four corners instead of two." The Dove IQ Turn is expected to find its market in the growth of heavy-duty turning in the oil and mining sectors.
Deep, Vibration-Free Cutting When tools get long, they tend to vibrate—especially as cutting speeds increase. The cutting force tries to bend
