Kennametal HiPACS aerospace fastener tool drills, countersinks in one step

Kennametal has introduced the HiPACS drilling and countersinking system for aerospace fastener holes. Designed to drill and chamfer holes in one operation, the high-precision tool meets the aerospace industry's stringent accuracy requirements, while delivering increased tool life in machining composite, titanium, and aluminum aircraft skins, says the company.

The system comprises three components: a reducer sleeve, countersinking insert, and solid-carbide drill. The system works with any standard hydraulic chuck.

The reducer sleeve has a built-in, high-precision pocket seat. In conjunction with a standard hydraulic chuck, this component provides secure clamping and a runout of no more than 3 µm.

The PCD countersinking insert eliminates the need for custom step drills, reducing manufacturing costs while meeting the industry´s accuracy requirements, states the manufacturer.

The two series of solid-carbide drills, both of which are diamond-coated and PCD-tipped, are suitable for the material combinations found in a typical aerospace assembly. In addition, the straight-shanked tools allow for length adjustments in increments of 10 mm.
