Chicago-Latrobe 41786 Jobber Drill Bit
The Chicago-Latrobe 41786 is a high-speed steel jobber length drill bit finished with titanium nitride. It features a 135-degree split point for accurate starting and reduced walking. This bit is designed for general-purpose drilling in metal, wood, and plastic. It suits maintenance technicians and workshop professionals needing reliable hole-making.
Suited for metal and wood drilling
This bit suits users drilling mild steel, aluminium, wood, or composite materials where a split point aids centring. The TiN coating extends life in abrasive or high-speed applications. It is not for buyers who need coolant-through capability for deep-hole chip evacuation. It also does not suit applications requiring a carbide substrate for hardened steels or high-volume production runs.
0.3230 inch decimal equivalent size
The drill bit size is designated as Letter P with a decimal equivalent of .3230 inches. This specific diameter determines the hole size produced and must match the fastener or tap drill chart requirement for the job. Verify the .3230 inch dimension against your engineering drawing or tap chart before purchase.

Questions about this item
What drill chuck size is required for the 0.3230-inch diameter shank?
A 3/8-inch or larger three-jaw chuck will grip the 0.3230-inch shank securely.
Will the 135-degree split point work in a hand drill without a pilot hole?
Yes, the 135-degree split point is designed to start on contact and reduce walking in hand-held drilling.
How can I confirm the TiN coating is intact after first use?
The cutting edges should retain a uniform gold colour with no blue discolouration or visible wear on the split point.
