Drilling accurate holes o round stock can be a big challenge. • Using micro spot drills can improve hole location and tool life of a deep hole drill or micro drill. • This video shows an easy way to do it with precision on brass pieces. • Nine9 X060A90 Micro carbide spotting insert geometries are short to optimize rigidity and accuracy with a point angle to guide micro drill towards the hole's centerline. It produces a consistent surface for micro drill to enter the workpiece especially for round, angled or curved surfaces. • X060A90 Micro carbide spotting insert has different coating, not only can spotting on non-ferrous metal but also spotting for all kinds of steel, cast iron and hardened steel up to 56 HRC. • More information: • https://nine9.jic-tools.com.tw/X060-M... • #Nine9 • #mirco_spot_drill • #mirco_drill • #X060_V_insert • #round_stock
