Digital-Ready Boring Tools

A line of digital-ready fine boring tools, the eBore Fine Boring System, make precision adjustment easy, enabling more productive, predictable, and accurate boring. The system consists of cutting units to cover a diameter range from 6 to 1,020 mm (0.236 to 40.157 in.) and an optional digital display that makes precision adjustments as simple as turning a screw.

With the eBore digital device, dialing in a tight bore and losing count of how far the adjustment screw was turned is a thing of the past. With an adjustment accuracy of 0.002 mm (0.00008 in.), the chip and coolant-resistant device contain a glass-scale that keeps track of boring bar movement. Simply snap it in place, turn the boring head´s adjustment screw by the desired amount, and the tool is ready for the next boring operation.

With eBore, there is no need to remove the boring head from the spindle for adjustment nor to count graduations or take notes. The device shuts off automatically after 30 seconds and provides more than 5,000 adjustments between battery changes. And if you forget to remove the boring head before turning on the spindle, a ball and spring clamping mechanism releases the display automatically at 500 RPM, preventing potential injuries.

Built on simplicity, the eBore system comes with Kennametal´s KM quick-change interface and can be easily adapted to HSK, PSC, KM4X, and steep taper spindles.
