High-speed steel drill bit with a 1/2 in reduced shank and 118-degree point angle for general-purpose drilling
The Chicago-Latrobe 52444 is a high-speed steel drill bit with an 11/16 inch cutting diameter and a 118-degree point angle. It features a 1/2 inch reduced shank to fit standard drill chucks. The black oxide finish provides corrosion resistance during metalworking tasks.
High-speed steel construction maintains hardness at elevated temperatures generated during prolonged cutting. The 118-degree point angle centres the bit quickly and reduces wandering on flat surfaces. Black oxide finish helps retain lubricant and dissipate heat during continuous operation.
The reduced shank limits the maximum chuck capacity required to 1/2 inch, enabling use with common portable drills. Shank diameter restricts torque transmission compared to full-size shanks. The 11/16 inch cutting diameter exceeds the shank size, so the bit cannot pass through its own pilot hole.

The black oxide finish on the 11/16 in bit helps dissipate heat while the 118-degree point angle reduces friction, keeping temperatures manageable during prolonged use in metal.
The 1/2 reduced shank fits any standard 1/2 in drill chuck, so a drill with a 1/2 in capacity is needed to secure the 11/16 in bit properly.
The 118-degree point angle is a general-purpose geometry that cuts efficiently in metal with moderate torque, making it suitable for older drills when paired with the 1/2 reduced shank.
