29-Piece Cobalt Jobber Drill Set
This Cleveland C70365 set contains 29 cobalt jobber-length drill bits built to the NAS907 Type J standard. The straw-bronze finish identifies the heavy-duty cobalt construction. It is suited for professional mechanics and maintenance teams drilling high-tensile alloys.
For high-tensile alloy drilling
The 135-degree split point reduces walking on hard materials such as stainless steel and titanium. Buyers who only drill mild steel, wood or plastic will not need the cobalt substrate. Shops requiring shorter screw-machine lengths or longer taper-length bits should select a different set.
NAS907 Type J heavy-duty standard
The set meets the NAS907 Type J specification for heavy-duty cobalt jobber drills. This single standard governs the geometry and material grade that determine whether the bits match your application requirements.
Highlights
- 29 cobalt bits cover common sizes
- 135-degree split point reduces walking
