The range of carbide burrs available from Chesterfield-based Dormer Pramet has been expanded by new tools designed to meet ‘the most demanding metal-finishing needs’ in nickel and titanium alloys (
www.dormerpramet.com).
With an ‘advanced cutting geometry’, the alloy-specific (AS) burrs support high-performance cutting and a smooth controlled cutting action for a consistent high-quality surface finish.
They can be used for deburring and chamfering in maintenance, repair and overhaul applications in industries such as aerospace and power generation.
With nine different shapes available, the AS burrs achieve a fast cutting action with high stock removal and are included in a new cutter set (P88006) featuring a variety of styles.
Dormer Pramet has also launched a new range of burrs specifically designed to prepare the clean removal of ‘broken bolts’, without damaging the threaded hole or the component.
Suitable for repair shops and maintenance applications, these are available in plain cylinder with end cut and 150deg countersink cut styles.
Various diameters and cutting lengths cater for different thread sizes, with long-reach and tapered-shank designs providing easy access.
A specially developed geometry accommodates the cutting of case-hardened threads and maximises the potential for drilling on the centre.
These new additions support Dormer Pramet’s existing assortment of burrs for steel, stainless steel, non-ferrous material, plastic, fibreglass, composites and general machining.
