Chicago-Latrobe 54106 Cobalt Jobber Drill

The Chicago-Latrobe 54106 is a jobber length drill bit made from HAWA cobalt material with a TiN coating. It features a 135 degree split point for self-centering and reduced thrust. The bit is designed for general purpose drilling in metal.

Suited for metalworkers needing a durable cobalt bit

This bit suits machinists and mechanics drilling tough alloys or stainless steel where cobalt heat resistance matters. Buyers who want more storage for multiple sizes should look at a set. Builders who need a second card for different diameters will need additional bits.

135 degree split point with TiN coating

The 135 degree split point angle is the specification that decides if this is the right part. It determines the drill's self-centering ability and chip evacuation in hard materials. The TiN coating adds surface hardness. Verify the decimal equivalent .2610 matches your required hole size.

Questions about this item

How do I install the 135-degree split-point cobalt drill bit and what step is often missed?

Chuck the bit securely in a drill press or hand drill, then start the hole at low speed with firm pressure so the split point self-centres without a centre punch.

What maintenance or replacement will the TiN-coated cobalt bit need later?

The TiN coating reduces wear; resharpen the 135-degree split point on a cobalt-approved grinder when cutting slows, otherwise replace the bit.

At what point does the .2610-inch jobber-length bit hit its limit under sustained drilling?

Heat buildup in the workpiece is the first limit; use cutting fluid and peck drilling to keep the cobalt substrate from overheating.
