OSG Jobber Drill HSS-E - For Stainless Steels, Steels and Ali - EX-SUS-GDR-3.81mm Boring Bar Blank This insertThis 3. 81 mm jobber drill bit is made from HSS E to handle stainless steel, standard steels, and aluminum in one tool. Its length and point design suit both bench work in workshops and on site tasks where reliable hole quality is needed without frequent bit changes. Heat and wear resistance: The HSS E material maintains its edge when drilling stainless steel that tends to harden during cutting, so the bit lasts through repeated use on tough jobs.
