Chicago-Latrobe 46614 Cobalt Drill Bit
This Chicago-Latrobe 46614 jobber length drill bit is made from cobalt steel for drilling hard metals. It has a 7/32 inch diameter and a 135 degree split point for accurate starting. The straw bronze finish identifies the cobalt construction.
Suits metalworkers needing heat resistance
Machinists and maintenance technicians drilling stainless steel or tough alloys benefit from the cobalt material. Woodworkers or DIY users drilling only soft materials will not need this level of heat resistance and can choose lower-cost bits.
Handles 7/32 inch holes in hard alloys
The cobalt steel maintains hardness at high temperatures when drilling stainless steel or high-strength alloys. The jobber length provides standard reach for common drilling depths. It lacks coolant holes so deep holes in difficult materials may require frequent withdrawal to clear chips.

Questions about this item
What chuck size do I need to hold the 7/32 in shank?
A 3/8 in or larger drill chuck will grip the 7/32 in shank securely.
Will the 135 degree split point start cleanly in work-hardened stainless that my older high-speed bits skate on?
Yes, the 135 degree cobalt split point is designed to self-centre and cut hard alloys without a centre punch.
How do I confirm the bit is cutting correctly once installed?
It should produce short, straw-coloured chips and advance steadily at low RPM with firm pressure.
