A3216.8

HSS Intermediate Length Drill, Steam and Bronze Tempered Surface Finish
Material ID: 8349666

Heavy duty design drill with three-flat shanks for medium depth holes. Diameter 6,8 mm with an overall length of 97 mm. Primarily suited for hand-held operations and pillar drill machines. Three flats on the shank allow for non-slip chucking. The self centering 135° split point reduces thrust force and the steam and bronze tempered surface finish improves lubricity. Suitable for drilling primarily in wide range of thin walled materials.
