Greenleaf Corp.’s GSN100 silicon-nitride inserts are for machining cast iron parts, such as cylinder blocks and heads, gear cases and housings, and brake drums and rotors. Blended with proprietary toughening agents, the inserts can achieve cutting speeds up to 5,000 sfm (1,525 m/min.) when single-point turning, grooving or milling, according to the company. The inserts can be ordered with special geometries and edge preparations for specific applications. (800) 458-1850.

BLIND-HOLE TAP.

The Walter Prototyp Paradur Short Chip HT blind-hole tap from Walter USA LLC reportedly increases process reliability and quality when tapping long-chipping, high-tensile-strength steel. The tap prevents the coiled swarf, or “bird’s nest,” from forming when threading, according to the company. The tool has a 15° helix angle for enhanced chip evacuation. This reduces to a 9° helix angle in the lower section of the tool, which creates short chips when combined with a ground rake in the chamfer. The tool is also suitable for tapping low-tensile-strength materials. (800) 945-5554.

MINIATURE DRILLS.

Mikron Corp. Monroe’s CrazyDrill Flex solid-carbide drills have a flexible center between the drill section and the clamping shank, which provides elasticity. The through-coolant drills start at 0.3mm (0.012 “) in diameter, increasing in 0.05mm (0.002 “) increments for standard tools and 0.01mm (0.0004 “) increments for specials, and are for drilling up to 50 diameters deep. In addition to conventional cutting fluid, users can apply a lubricant that combines air, oil and mist. (203) 261-3100.

WHEEL, NOZZLE CHANGER.

Rollomatic Inc. offers an optional six-station wheel and nozzle changer for its GrindSmart series 5-axis 528 and 6-axis 628 CNC grinding machines. The changer is suited for grinders that make specialty and custom rotary cutting tools, and perform continuous production grinding and tool modification and regrinding. The changer can replace wheel packs while an automatic loader places a new blank into the machine without increasing cycle time, according to the company. (866) 713-6398.

TAILSTOCK FORCE GAGE.

For precision jobs using face drivers, Riten Industries Inc. says its tailstock force gage, in conjunction with the tailstock’s hydraulic cylinder pressure reading, accurately calibrates a lathe or grinder to deliver the precise load for fast setup and repeatable, scrap-free production. The antivibration analog gage displays force from 200 to 6,000 lbs. (90.7 to 2,721.6 kg). It features dual indicators: The black needle shows actual force in real time, while the red needle becomes permanently set at the highest reading recorded during the procedure. (800) 338-0027.

SOLID-CERAMIC ENDMILLS.

Beyond KYS40-grade solid-ceramic endmills from Kennametal Inc. rough nickel-base alloys at up to 3,300 sfm (1,000 m/min.) and last two to three times longer than comparable solid-carbide tools, according to the company. The tools have an enlarged core to enhance rigidity and reduce deflection at high cutting speeds and a 40° helix to increase shearing action and chip evacuation. Two types of endmills are available: a 6-flute version for facemilling and profiling and a 4-flute, necked version for slot milling and pocketing. (800) 446-7738.

COLLET CHUCK.

Based on the ER collet standard, the FAHRION Centro P collet chuck from HORN USA Inc. provides a total indicator runout of less than 3µm at 3 times diameter and is balanced for speeds up to 30,000 rpm. The system’s rigid construction dramatically reduces vibration to impart high-quality surface finishes and extend tool life and, compared to the ER standard, is six times more precise and increases clamping forces 100 percent, according to the company. (888) 818-4676.
