7/32-inch split-point jobber drill
The Chicago-Latrobe 42014 is a high-speed steel drill bit designed for general-purpose drilling in metal and wood. Its 135-degree split point reduces walking and starts holes cleanly without a centre punch. The TiCN coating adds surface hardness and extends cutting life in abrasive materials. It suits mechanics, fabricators and maintenance technicians who need reliable fractional-inch tooling.
TiCN-coated HSS construction
High-speed steel provides the toughness required for hand-held and machine drilling. The titanium carbonitride coating lowers friction and resists heat buildup during extended cuts. A 135-degree point angle with wide-land parabolic flutes improves chip evacuation in deeper holes. The straight shank fits standard three-jaw chucks and quick-change adapters without additional sleeves.
Replaces worn or uncoated jobber bits
This bit upgrades from standard black-oxide or bright-finish drills when longer tool life and faster starts matter. The split-point geometry eliminates the need for secondary spotting operations in many materials. It is not suited for coolant-through applications or hardened steels that demand carbide tooling. Choose it when a durable, non-coolant fractional drill is required.

Questions about this item
What is the 135° split-point angle designed to do?
The 135° split-point angle centres the bit on contact, reducing walk and cutting thrust required in hard materials.
What shank diameter does the 7/32 in jobber drill require?
The 7/32 in drill has a matching 7/32 in shank, so it fits any standard three-jaw chuck that accepts 0.2188 in.
How is the TiCN coating applied and what mistake shortens its life?
The TiCN coating is applied to the high-speed steel body; running the drill without lubrication or at excessive speed overheats the edge and degrades the coating.
