New Deep-Hole Drill Launched by Dormer Pramet
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 aluminium, the R459 has been specifically developed to overcome problems typically associated with deep-hole drilling.
Created within the Dormer product portfolio, the R459 broadens the existing MP-X range which already consists of 3xD and 5xD solid carbide multi-material drills.
A key feature of the new drill is its Continuously Thinned Web (CTW) geometry which increases both flute volume and cross sectional strength.
Ricky Payling, Dormer Pramet’s application specialist for rotary tools, explains: “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. 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 140º point angle makes for easier centring and reduces thrust requirements.
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, minimising machine downtime.
The R459 is available in diameters from 3mm – 16mm, including 0.1mm increments up to 10.0mm, and features a titanium aluminium nitride (TiAlN) coating.
Ricky added: “Including an 8xD drilling option to the current MP-X range enhances our customer offer and provides a reliable, versatile and cost-effective solution.”
Included within Dormer’s new 2015 rotary tooling catalogue, the 8xD drill is available to purchase from 1 January 2015.

Dormer is a product brand within Dormer Pramet.
The merger of round tools manufacturer Dormer Tools and cemented carbide tooling specialist Pramet Tools was instigated in 2014. The combined product programme now encompasses a comprehensive range of rotary and indexable drilling, milling, threading and turning tools for the general engineering sector. An expanded sales and technical support service extends to over 30 offices serving more than 100 markets worldwide. These are supported by state-of-the-art production facilities in Europe and South America and a global distribution network consisting of five strategically placed hubs.
