Premium High-Speed Steel (HSS) micro cutting tools containing roughly 5% Cobalt for applications requiring a low-cost solution with the strength to withstand unusually high cutting forces.
A pilot or spot drill, also known as a starter drill, is typically required when the succeeding drill is longer than 10xD or smaller than Ø 1.00 mm. Starter drills can also be used to improve hole location due to their short, rigid geometries.
We provide DXF drawings, a cutting data calculator and drill size conversions. You can also download all our product catalog PDFs or watch our product videos.
