Two specific concerns with plasma holes are the taper and the ding or divot that is present on the interior of the hole. Both of these cut quality issues prevent a bolt from being able to pass through the hole; therefore, operators typically would have to perform secondary operations in order to improve the roundness of the hole to the point where a bolt would cleanly fit. After years of research, Hypertherm developed True Hole Technology in order to address these concerns.
For parts that are less than 0.125" (3.18-mm) in diameter, Tungaloy America Inc. introduced a series of high-positive, low-cutting-force, screw-down, dead-sharp inserts and toolholders last year. There are four chipbreakers: JS features a molded chipbreaker and the JRP, JPP, and JSP inserts.

"Back in 2008, Hardinge introduced a low-profile rotary table as a standard, no-frills unit to compete against other 210mm tables on the market," states Al Comstock, Rotary Product Manager at Hardinge Inc. "Now, by customer demand, we've redesigned the model to include the infamous Hardinge collet-ready 16C spindle that provides the high-precision gripping options for which Hardinge is known. We've also extended the spindle nose for additional tooling clearance."
To meet the growing demand from the energy/powergen sector, ISCAR has launched a line of extra-strength standard grooving tools for more efficient and secure machining of T and L slots so common in turbomachinery.
In deep-hole drilling applications up to 30XD, new solid-carbide WIDIA-Rubig deep-hole drills reportedly remove between three and four times the metal compared to gun drills, in addition to delivering excellent hole quality and cycle times.
