Which drilling solution suits your needs?
When drilling small to medium holes, there are different drilling solutions to choose from:
Exchangeable tip drills
Indexable insert drills
Solid carbide drills
When selecting your drill type, there are many aspects to consider. Hole tolerance, driling depth anddiameter are of primary importance, Further, the work piece material, desian of the component, batchsizes and machine type needs to be considered.
Generally speaking, symmetrical drills such as solid carbide or exchangeable tip will provide closer holetolerances and operate at higher feed rates. indexable insert drills are very cost efficient when holetolerance is not of primary importance and since being run at lower feeds they impose lower amountsof axial forces into the work piece.
