Chicago-Latrobe #52 Cobalt Drill Bit
This Chicago-Latrobe jobber length drill bit is sized at #52 with a 135 degree split point. The cobalt construction handles hard metals and stainless steel. It suits mechanics and machinists drilling precise small holes in tough materials. The decimal equivalent is 0.0635 inches.
Suits hard-metal drilling; not for large diameters
This bit suits users who need a #52 cobalt tool with a 135 degree split point for accurate starts in hard alloys. Buyers who want more diameter or a different point angle should look at something else. It has no coolant holes and is non-coolant through.
#52 size with 135 degree split point
The single specification that decides fit is the #52 size combined with a 135 degree split point. This determines the hole diameter and the self-centering behaviour in hard material. Match this size and angle to your drawing or tap chart before ordering.

Questions about this item
Should I choose the #52 size or a different wire gauge?
The #52 wire gauge has a decimal equivalent of .0635 inches; select it when your hole diameter matches that size.
How does the 135-degree point angle affect drilling performance?
A 135-degree split point centres itself faster and reduces wandering on hard metals such as stainless steel.
What does the cobalt material mean for heat resistance and tool life?
Cobalt alloy retains hardness at higher temperatures, extending edge life when drilling tough alloys compared to standard high-speed steel.
