HGV Water Plug Machining Tool

The tool's CERATIZIT R84 fine boring indexable inserts feature a brand new reaming geometry specifically designed for exceptional hole finishing. The new positive geometry generates extremely low cutting forces and includes a new chip breaker that improves chip control. All of which allows for higher feed speeds while at the same time producing a better surface quality. Plus, the new inserts provide a much longer tool life as compared to their predecessors.

J12/J/16 Jig Borer

The machines' strong and durable structures provide table lateral movement accuracy of 2.5 µm or better. The Z-axis guide system is restrained on four sides to maximize rigidity and reliability, and dual ball screws ensure stable feed motion. For precision holemaking applications, XY interpolation enables the J12/J16 machines to carry out high-precision contouring by utilizing an end mill instead of a boring tool, eliminating the need to manually adjust a boring tool to accurately finish the hole diameter avoiding bottlenecks. Pitch accuracy is within 5 µm even for large-pitch holes.

DMH Drill Head Line

The DMH drill head features a fracture resistant design that is suitable for applications that involve drilling holes through thin-walled sections of workpieces. In normal circumstances, thin walls tend to spring back on the drill after the drill pierces through and exits the hole. In the process, uncut material shifts and forms exit burrs that impose extra burdens on the drill edge. These problems inflict damage on drill corners, shortening tool life. The DMH drill head's geometry protects drill corners from fracture damage, providing extended tool life and reduced downtime.

420 (410) Series Fine Boring Heads

As the world's smallest digital fine boring tool with a peripheral cutting edge, the unbalanced 420 (410) series has a diameter range of 0.787 inches – 1.142 inches (20.00 millimeters – 29.00 millimeters). The 465 (464) boring heads offer automatic self-balancing and bore diameters from 1.142 inches – 8.071 inches (29.00 millimeters – 205.00 millimeters). These boring heads have a special design to minimize the residual imbalance produced by insert holder displacement.
