Chicago-Latrobe 55492 118 Degree Silver & Deming Drill 1/2 Reduced Shank

Chicago-Latrobe 55492 Silver & Deming Drill

This Chicago-Latrobe drill bit is a Silver & Deming style cutter designed for general-purpose drilling in metal, wood and plastic. It suits machinists, maintenance technicians and serious DIY users who need a large-diameter hole with a standard 1/2 inch reduced shank. The high-speed steel construction handles routine workshop tasks.

118-degree point angle for broad material

The 118-degree point angle is the critical specification that determines how the bit engages the workpiece. This conventional angle centres easily without a pilot hole and cuts cleanly in mild steel, aluminium, cast iron and non-ferrous metals. It is less aggressive than a split-point design but more forgiving on portable drills.

1/2 inch reduced shank fits standard drill chucks

The reduced shank allows the 1 7/16 inch cutting diameter to be used in any drill with a 1/2 inch chuck capacity, freeing the operator from needing a larger drill press or a Morse taper adapter. Black oxide finish adds lubricity and corrosion resistance during extended use. High-speed steel body resists heat build-up in handheld applications.
