Step drill with 90° included step angle, straight shank and a drilling-pilot diameter of 6.60mm with a length of 15.00mm, a large diameter of 13.00mm and an overall length of 102mm, according to DORMER standard to produce a medium fit through hole and conical seat for M6 countersunk-head screws, HSS and steam tempered finish for machining free machining, plain carbon and alloy steel, ferritic and martensitic stainless steel and grey cast-iron
Applications:
P - Steel and cast steel(steels with alloy content ? 10% and a hardness of < 45HRC) - Primary use
M - Stainless steel(corrosion resistant steels with ? 11% chromium content) - Primary use
K - Cast Iron(castings of iron and carbon alloys with > 2% carbon content) - Primary use
N - Non-ferrous metals(metals including alloys without an appreciable amount of iron) - Possible use
S - High-temperature alloys(superalloys with high temperature stength and corrosion resistant surpassing that of stainless steel) - Possible use
