Chicago-Latrobe 45624 Drill Bit
The Chicago-Latrobe 45624 is a jobber length drill bit built for general-purpose drilling tasks. It features a 135 degree split point designed to start on contact and reduce walking on metal surfaces.
Check your chuck capacity and material
Verify that your drill chuck accepts a 3/8 inch shank before ordering. The high speed steel construction with black oxide finish is intended for drilling steel and other ferrous metals rather than masonry or glass.
Suited for metalworkers needing a 3/8 inch bit
This bit suits machinists and maintenance technicians who need a 3/8 inch high speed steel drill with a 135 degree point. It is not for buyers who require coolant-through capability or a different diameter for their specific application.

Questions about this item
Does the Chicago-Latrobe 45624 3/8-inch drill bit come as a single piece or in a set, and is a drill chuck included?
The product is supplied as one individual 3/8-inch jobber length drill bit. A drill chuck or any other accessory is not included and must be purchased separately if required.
What does the 135-degree split point on the 45624 bit mean for starting holes in steel?
The 135-degree split point is designed to self-centre on contact, reducing walk and allowing faster penetration in hard materials such as steel without the need for a centre punch.
How does the black oxide finish on the high-speed steel 45624 bit affect its performance in a hand drill?
The black oxide finish helps retain cutting lubricant and reduces chip welding, which extends cutting life and improves chip flow when drilling steel with a portable hand drill.
