New deep-hole drill launched by Dormer

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.

The drill also broadens Dormer''s 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''s drilling product manager, 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.

Dormer''s 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 catalogue, the 8xD drill is available to purchase from 1 January 2015.

A drill, a legend – 20 years of A002

When a new jobber drill was launched at the turn of the millennium, many people did not realize the impact it would have on the metalworking industry.

Now, 20 years later, the Dormer A002 has become one of the most iconic drills in the market, with millions sold around the world every year, but more importantly, it helped keep High-Speed Steel (HSS) the go-to option for machine shops around the world. At the time the A002 was introduced, the standard HSS twist drill had barely changed in more than a century, with m...

Have you considered the benefits of bar peeling?

Bar peeling is a specialist application which requires relatively high feed rates and small depth of cut applied to round bars and thick-walled tubes.

Operations include the removal of surface layers of oxides, rolled contaminants and cracks caused by hot forging or rolling. This is mostly done in carbon steel, alloy steel for heat treating, tool steel, stainless steel, and heat–resistant alloys. The advantages of peeling in comparison with turning are higher productivity, less inserts consumption, excellent roughne...
