Chicago-Latrobe 54014 Cobalt Drill Bit

This Chicago-Latrobe 54014 jobber-length drill bit is made from cobalt steel for drilling hard metals. The TiN coating adds surface hardness and reduces friction during use. It suits professional mechanics and maintenance teams who need reliable performance on tough alloys.

135° Split Point for Self-Centring

The 135-degree split point starts on contact without a centre punch. This geometry reduces walking on curved or hardened surfaces. It is the single specification that determines suitability for stainless steel, titanium and other difficult materials.

#4 Wire Size .2090 Decimal Equivalent

The #4 wire gauge yields a .2090-inch diameter for precise hole sizing. Jobber length provides standard reach for general machine and hand-held drilling. Cobalt construction resists heat buildup but will wear faster than carbide in high-volume production runs.

Questions about this item

How does the 135-degree split point affect drilling in hard metal?

The 135-degree split point centres the bit on contact and reduces walking, so it starts cleanly in tough alloys such as stainless steel without a centre punch.

What does the TiN coating do for tool life in production drilling?

The titanium nitride layer lowers friction and heat, letting the cobalt substrate hold its edge longer in repetitive drilling of work-hardening materials.

Will the #4 .2090-inch shank fit a standard three-jaw drill chuck?

Yes — the .2090-inch diameter is well within the capacity of any common 3/8-inch or 1/2-inch keyed or keyless chuck.
