Dormer Pramet: Delivering security when you need it
Dormer Pramet has expanded its existing range of forming taps for standard thread forms MF, UNC and UNF, as well as adding taps with oil grooves and through coolant.
The Dormer forming taps are a dependable option when creating threads, offering both dynamic strength and high dimensional accuracy. The comprehensive program now includes designs and thread forms for the majority of applications and materials across all major industry segments.
The five new lines of forming taps, added as part of the company’s November 2016 launch, offer greater accuracy and produce a stronger thread than standard cutting taps with increased load bearing capabilities.
Manufactured from High Speed Cobalt (HSS-E), the taps provide lower surface roughness and a highly stable design, reducing the risk of breakage for added operational reliability.
Available with Titanium Nitride (TiN) or Titanium Carbon Nitride (TiCN) coatings, the taps thread profile generates low torque, reducing friction and ensuring a smooth surface finish. The chamfer geometry provides a better run-in and even wear, with options for blind and through-hole machining.
Meanwhile, Dormer Pramet has launched a comprehensive program of solid carbide taps for machining hardened steels and other difficult to machine materials.
The use of hardened materials in industrial processes is becoming increasingly common, creating a greater need for cutting tools that can operate in extreme conditions.
To support this, Dormer Pramet has developed five new lines for threading depths up to 3xD under its Dormer brand.
The new carbide taps – identified by the T2xx designation – form part of the company’s second product launch of 2016.
Offering a high level of performance and productivity, the taps are recommended for machining hardened materials up to 63 HRC, providing high wear resistance and long tool life even at high speeds.
The T2xx range can support cutting speeds three times greater than HSS-E taps and, with a highly stable tool design, offers less risk of breakage.
The taps are available in a choice of straight flute and spiral flute geometries with either a Titanium Carbon Nitride (TiCN) or Super-B (TiAlN + WC/C) coating. Through coolant and forming tap options have also been added.
