Chicago-Latrobe 50828 Drill Bit

The Chicago-Latrobe 50828 is a screw machine drill bit sized at 31/64 in with a 135-degree split point. It is made from cobalt and has a straw finish. The cutting direction is right hand and the decimal equivalent is .4844. This bit suits machinists who need a precise hole in metal.

Suited for general metal drilling.

This bit fits jobs that require a standard right-hand cobalt drill with a split point for self-centering. It will not suit buyers who need coolant-through capability or a left-hand cutting direction. Builders who need a different diameter or point angle should look at another size.

31/64 in diameter with 135-degree split point

The single specification that decides fit is the 31/64 in diameter combined with the 135-degree split point. This exact size and angle determine whether the bit matches the hole required. Verify the decimal equivalent of .4844 against your drawing before purchase.

Questions about this item

How can I confirm the drill bit is cutting correctly after installing it in my drill press?

What comes in the package and do I need any extra accessories to use the bit?

The box contains the single 31/64-inch cobalt screw machine drill bit; no additional accessories are required for standard drilling.

Which version should I choose if I need the 0.4844-inch decimal size for a specific hole tolerance?

This model 50828 is the 31/64-inch size with a 0.4844 decimal equivalent, matching that exact tolerance.
