9.00mm Cobalt Jobber Drill
This 9.00mm cobalt jobber drill is built for machinists and maintenance technicians who need a reliable hole-making tool for tough alloys. The heavy-duty construction suits professional workshops and serious hobbyists working with stainless steel, tool steel, alloy steel and titanium.
135-degree split point for hard metals
The 135-degree split point reduces walking and lowers thrust when drilling stainless steel, tool steel, alloy steel and titanium. Cobalt steel construction maintains hardness at elevated temperatures, while the straw/bronze finish adds wear resistance. Manufactured to NAS 907 Type J standard, list number 2213.
Straightforward use in standard equipment
The right-hand cutting spiral flute fits any 9.00mm capacity drill chuck without adapters. The 125.00mm overall length and 81.00mm flute length provide standard reach for through holes. Common issues arise only if feed pressure is excessive or coolant is neglected in deep cuts.

Questions about this item
What does the 135-degree split point mean when I start drilling?
The 135-degree split point centers the bit on contact and reduces walking, so you can begin holes in stainless steel, tool steel, alloy steel or titanium without a centre punch.
How does the NAS 907 Type J standard affect the way the bit performs?
NAS 907 Type J defines the heavy-duty cobalt construction and geometry for aerospace-grade drilling in hard metals, giving consistent chip clearance and heat resistance during extended cuts.
What chuck size and clearance do I need for the 9.00 mm shank and 125.00 mm overall length?
You need a chuck that opens to at least 9.00 mm and enough spindle travel or workpiece clearance to accommodate the 125.00 mm overall length and 81.00 mm flute length.
