Cobalt High Speed Steel
135° Split Point
Jobbers length drills are designed to perform in a wide variety of
normal conditions and in a broad range of materials in both machine
and portable drilling. Cobalt HSS is used for drilling
in tough, high tensile strength materials. Drills are made of heat
resistant, 8% cobalt high speed steel, with heavy duty flute construction
and 135° Split point.
The wide land
parabolic design provides superior performance in a greater range
of materials and applications. Especially effective in deep hole
drilling; unique flute form produces closer tolerances due to
improved chip and coolant flow, and higher torsional rigidity.
135° self-centering split point reduces thrust.
