AYSWJSD-CUHSS Straight Shank Drill for Brass SD-CUSold0pcsThe WJ HSS Straight Shank Drill for Copper SD-CU is ground specifically for copper and brass. The rake geometry is the difference: copper is ductile and grabby, and a general drill often self-feeds - snatching into the work. The copper geometry adjusts rake and helix so entry is steadier and the bore less likely to open up. For aluminium there is the dedicated SD-AL, both are available in cobalt versions for more heat resistance, and for steel use SD or the cobalt STD. Substrate HSS, uncoated, rated to HRC30. Sizes cover diameter 0.5~13mm, flute length 7.5~114mm and overall length 27~152mm, in 126 variants. Made in Taiwan. Why does copper grab? It is soft and sticky, and with too much rake the drill pulls itself into the work - dangerous on thin sheet, where it can lift the part or drill off-centre. Can it drill steel? Not recommended; the listed materials are aluminium, copper and other non-ferrous metals. Typical applications: drilling copper and brass components, electrical conductor parts, and openings in thin copper sheet.
