Chicago-Latrobe 42024 Jobber Bit

The Chicago-Latrobe 42024 is a jobber-length drill bit designed for general-purpose drilling in metal. It targets machinists and maintenance technicians who need a reliable high-speed steel cutter for standard workshop tasks.

3/8 inch capacity with 135° split point

The 0.3750-inch diameter handles common fastener clearance and tapping sizes in steel and cast iron. The 135-degree split point reduces walking and lowers thrust, but the bit lacks coolant-through capability for deep-hole chip evacuation.

TiCN coated high-speed steel for machine use

The HAWA high-speed steel substrate with TiCN coating resists wear in production drilling on drill presses or milling machines. The straight shank fits standard three-jaw chucks and collets, freeing the operator from specialised holders.

Questions about this item

Will the 135° split point on this 42024 drill bit start cleanly in the same materials my older bits handle?

The 135° split point is designed to self-centre and reduce walking, so it starts holes reliably in steel and other metals where a standard point might wander.

How can I confirm the 42024 bit is cutting correctly once I begin drilling?

A properly cutting bit produces short, curled chips and advances with steady pressure; if it generates excessive heat, squeals or only makes dust, the point may be dull or the speed too high.

Does the 42024 package include any lubricant or coolant, or must I supply my own?

The bit is non-coolant-through with zero coolant holes, so cutting fluid or paste must be supplied separately; the box contains only the TiCN-coated high-speed steel drill bit itself.
