Chicago-Latrobe 43624 3/8 in Drill Bit
This Chicago-Latrobe 43624 is a jobber length drill bit made from high speed steel with a TiCN coating. It features a 135 degree split point designed for self-centering and reduced thrust. The fractional size is 3/8 in with a decimal equivalent of .3750.
Suits general metal drilling.
The split point geometry helps the bit start on contact without a centre punch. Builders who need internal coolant delivery should look elsewhere because this bit has zero coolant holes. The TiCN coating adds wear resistance for ferrous materials.
135 degree split point decides suitability
The 135 degree split point angle determines how the bit engages the workpiece and reduces walking. If your application requires a different point angle or a coolant-through design, this is not the correct part.

Questions about this item
Will the 135-degree split point on this 3/8-inch bit start cleanly in pilot holes made by older bits?
The 135-degree split point is designed to self-centre and reduce walking, so it tracks accurately in pre-drilled pilot holes without needing a centre punch.
How can I confirm the TiCN coating is performing correctly after the first few holes?
Check that chips evacuate cleanly and the cutting edges stay sharp with minimal heat discolouration on the workpiece.
Does the box contain only the 43624 drill bit or are extra accessories included?
The package contains the single 3/8-inch jobber-length drill bit with TiCN coating; no coolant accessories or extra bits are supplied.
