Sandvik Coromant Co. Drills For Composites CoroDrill 452

For aerospace rivet and bolt holes, you can’t go wrong with this assortment of new standard drills. Each carbon fiber material can be different, which then varies the risk for delamination or splintering. These drills, optimized for composite-stack and metallic-stack materials, ensure the stringent hole tolerances are met with exceptional finish and quality. Close hole tolerances, good surface finish Tools optimized by CFRP and metallic-stack material type Low-thrust geometries reduce risk of hole delamination and burrs Application Portable hand-held machines Aerospace rivet and bolt holes Carbon fiber reinforced plastics (CFRP) Carbon fiber reinforced plastic/metallic-sta ck materials ISO application area Features Tools optimized for hole making in carbon fiber reinforced plastics (CFRP): Composite drill CoroDrill 452.1…C​ Right-hand drill with left-hand helix counteracts thrust forces to increase hole quality Designed for smooth exits from CFRP material Avoids damage caused by straight flute design Point geometry developed for CFRP materials, including unidirectional material Use with drill bushing for improved hole tolerance to IT 0.05 mm (0.002 inch) Composite reamer CoroDrill 452.R…C Designed for close hole tolerances Step pilot to reduce thrust and improve hole quality Designed to reduce risk of hole delamination Pilot diameters matched to drill diameters of CoroDrill 452.1 and CoroDrill 452.4 PCD countersink CoroDrill 452.C…C Single-edge countersink to improve accuracy, optimized for CFRP materials PCD cutting edge gives longer tool life and resharpening capability Standard tools for 100° and 130° chamfer angle Correct chamfer depth ensured with micro-stop Wide range of radii, angles, and dimensions available as engineered solution Carbide pilot to improve accuracy Tools optimized for hole making in CFRP/metallic-stack materials:​ Composite-metal drill CoroDrill 452.1…CM For pre-drilled and non-pre-drilled applications For stacks of CFRP and aluminum, titanium, and stainless steel Self-centering drill point Tolerance to 0.05 mm (0.002 inch) with drill bushing Composite-metal drill with pilot CoroDrill 452.4…CM Drill pilot designed for pre-drilled and non-pre-drilled applications For high-quality holes with exceptional finish and quality Minimum force needed to complete hole Use with guide bushing for holes with minimum size difference between material stacks Self-centering drill pilot Tolerance to IT 0.05 mm (0.002 inch) with drill bushing Composite-metal reamer CoroDrill 452.R…CM Pilot diameters matched to drill diameters of CoroDrill 452.1 and CoroDrill 452.4 Designed to reduce risk of hole delamination Close tolerances to IT 0.02 mm (0.0008 inch)
