Chicago-Latrobe 42625 Jobber Drill Bit
The Chicago-Latrobe 42625 is a heavy-duty jobber length drill bit sized at 25/64 in with a 135 degree split point. It is made from High Speed Steel with a TiAlN coating for durability. This fractional inch bit suits general purpose drilling in metal and other materials.
Check shank fit and material suitability
Verify that your drill chuck accommodates a straight shank of this diameter before ordering. The bit has a decimal equivalent of .3906 in and zero coolant holes, so it is designed for non-coolant through applications. Confirm the workpiece material matches high speed steel capabilities.
Sustained load behaviour with TiAlN coating
Under continuous drilling the TiAlN coating helps maintain hardness at elevated temperatures. The 135 degree split point reduces walking and lowers thrust force during extended cuts. The jobber length flute clears chips effectively to prevent binding in deeper holes.

Questions about this item
What comes in the box and do I need to buy anything else to start drilling?
The package contains the 25/64 inch jobber-length drill bit with a 135-degree split point made from high-speed steel with a TiAlN coating. No extra accessories are required to use it in a standard drill chuck.
How do I decide between the available versions or capacities for this drill bit?
This listing is for a single 25/64 inch size with decimal equivalent .3906 and part number 42625. Choose this bit when your project calls for that exact fractional diameter.
What does the 135-degree point angle mean once the bit is in my drill?
The 135-degree split point reduces walking and starts holes faster in metal, while the TiAlN coating on the high-speed steel body extends cutting life during repetitive drilling.
