New drill technology for composites
From 31sr March 2011 cutting tool and tooling specialist Sandvik Coromant will introduces a range of drills for producing rivet and bolt holes in carbon reinforced plastics (CFRP) and composite/metallic stack materials.
CFRP has properties that increase the risk for undesirable machining effects such as delamination, splintering or burr formation. Featuring new geometries, the CoroDrill® 452 range reduces the risk of these traits, ensuring that stringent hole tolerances are met with exceptional finish and quality.
As well as drills, the range for CFRP includes reamer geometries and a countersink tool with micro-stop for chamfering, while tools for composite/metallic stack materials include drills, drills with pilot, and reamers.
The CoroDrill 452 range can be used in fixed bed machine tools as well as portable and hand-held machines, making it particularly versatile in aerospace plants where portability is vital.
