New Deep-Hole Drill Launched

Dormer Pramet has launched a new solid carbide drill for applications up to 8xD. Suitable for machining a variety of materials including steel, stainless steel, cast iron, copper and aluminum, the R459 has been specifically developed to overcome problems typically associated with deep-hole drilling.

A key feature of the new drill is its continuously thinned web (CTW) geometry that increases both flute volume and cross sectional strength. "The combination of these elements ensures consistent forces throughout the drilling cycle, with little or no increase in power requirement as the drill penetrates deeper into the hole," said Ricky Payling, Dormer Pramet's Application Specialist for rotary tools. "This, in turn, allows increased cutting speeds and greater performance reliability without compromising tool life."

"A special outer corner design provides added protection against wear and chipping, especially when under extreme conditions such as cross drilling applications, while a specially designed 140° point angle makes for easier centering and reduces thrust requirements," said a company spokesperson. "The R459 also incorporates a consistent edge preparation, which protects against premature chipping and flaking. In addition, internal coolant holes allow for effective cooling of the cutting area and efficient swarf removal, minimizing machine downtime."

The R459 is available in diameters from 3 mm - 16 mm, including 0.1 mm increments up to 10.0 mm, and features a titanium aluminum nitride (TiAlN) coating.
