Chicago-Latrobe 41786 135 Degree Heavy-Duty Jobber Length Drill Bit

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.
