Drillco 5/32″ Cobalt Jobber Drill
Heavy duty construction made to Type J aircraft specifications. Used for drilling holes in hard, tough materials such as
stainless steel, titanium high temperature and high strength alloys. High red hardness of cobalt permits speeds 30%
greater than HSS drills.
Drillco 7/32″ Cobalt Jobber Drill
Heavy duty construction made to Type J aircraft specifications. Used for drilling holes in hard, tough materials such as
stainless steel, titanium high temperature and high strength alloys. High red hardness of cobalt permits speeds 30%
greater than HSS drills.
Drillco A – 2-5/8 ” 135° Split Point / Straight Shank Jobber Drill
The Nitro Heavy Duty 135 degree Split Point drill with Nitride surface treatment, that give a hard, protective layer to the drill (increases hardness without increasing brittleness), which is measurably harder than high speed steel. Body and clearance are black and gold surface treated for maximum lubricity. Recommended for use in stainless steel and other hard metal drilling.
Drillco C – 2-3/4 ” 135° Split Point / Straight Shank Jobber Drill
The Nitro Heavy Duty 135 degree Split Point drill with Nitride surface treatment, that give a hard, protective layer to the drill (increases hardness without increasing brittleness), which is measurably harder than high speed steel. Body and clearance are black and gold surface treated for maximum lubricity. Recommended for use in stainless steel and other hard metal drilling.
