Chicago-Latrobe 54073 Cobalt Drill Bit

This Chicago-Latrobe 54073 drill bit is a jobber-length accessory made from cobalt with a TiN coating. It features a 135-degree split point designed for self-centering and reduced thrust. The fractional size is 15/32 in with a decimal equivalent of .4688. It suits general-purpose drilling in metal and other materials.

Suited for metalworkers needing a durable

The bit suits machinists and fabricators who want a cobalt tool with a 135-degree point for harder materials. It is not for buyers who need coolant-through capability for deep-hole drilling. It is not for users who require a different diameter or point angle for a specific application. It is not for those needing a bit with coolant holes.

15/32 in fractional size with 135-degree split point

The defining specification is the 15/32 in diameter combined with a 135-degree split-point geometry. This determines the hole size produced and the bit's ability to start accurately without a pilot hole. Verify this exact fractional size matches your requirement before purchasing. The cobalt construction and TiN coating support wear resistance.

Questions about this item

What chuck size does the 15/32 in cobalt jobber bit require?

The bit has a 15/32 in diameter shank, so it needs a drill chuck that opens to at least 0.4688 in or a 1/2 in capacity chuck.

How should the 135° split point be started to avoid walking?

Use light pressure and low speed to let the split point centre itself; do not lean on the drill or the cobalt tip can chip.

When does the TiN-coated cobalt bit need replacement?

Replace it when the cutting lips show visible rounding or the split point no longer self-centres in steel.
