Chicago-Latrobe 42015 Jobber Drill Bit
The Chicago-Latrobe 42015 is a jobber length drill bit designed for general-purpose drilling in metal and wood. It suits mechanics, fabricators and maintenance technicians who need a reliable fractional-size bit for everyday workshop tasks.
135° Split Point with TiCN Coating
The decisive specification is the 135 degree split point combined with a TiCN coating on high speed steel. This geometry reduces walking at the start of the cut and the coating adds hardness and heat resistance for longer edge life in steel.
15/64 in Diameter Capacity
The bit drills a precise 15/64 inch hole, decimal equivalent .2344, making it suitable for tap drill and clearance work in that size range. It lacks coolant-through holes, so deep holes in tough alloys may require frequent pecking and external lubrication.

Questions about this item
How does the 135-degree split point affect drilling in metal?
The 135-degree split point centres the bit without a pilot hole and reduces walking on hard steel, giving faster starts and less pressure needed.
What does the TiCN coating do for this 15/64-inch bit?
TiCN increases surface hardness and heat resistance so the high-speed steel edge stays sharp longer in abrasive alloys and high-speed drilling.
Will this jobber-length bit fit a standard three-jaw chuck?
Yes, the straight shank on this 15/64-inch jobber drill fits any standard three-jaw drill chuck or collet that accepts fractional-inch sizes.
