HSS Screw Machine Length Drill Sets
Style 159
Short, HSS screw machine length. Rigid, heavy-duty
construction with 135° split point and black oxide finish to
reduce galling and chip welding. Particularly suitable for the most
demanding portable drilling applications and especially recommended
for use in sheet metal. Sturdy design resists strain under conditions
when longer drills may break. Split point eliminates "walking"
and reduces thrust forces.
