90° HSS-G countersinks according to DIN 335-C, cylindrical shank, robust design with 3 flutes. Due to CBN precision ground geometry very sharp and precise cutting edges, specifically for aluminium.

Aluminium countersinkbit for metal

Ideal for deburring or countersinking of aluminium and similar soft materials. Best results with low rpms. Material groups : 1.1 - 1.3 / 4.1 - 4.12 / 5.1 / 5.3

Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material. Learn more about Milling.
