Chicago-Latrobe 69860 8-piece reduced shank drill bit set

8-piece reduced shank drill bit set

The Chicago-Latrobe 69860 set contains eight drill bits built with a 1/2-inch reduced shank design. Each bit is manufactured from high-speed steel with a black oxide finish for corrosion resistance and wear protection. The 118-degree point angle provides a standard cutting profile for general-purpose drilling tasks in a workshop or job-site environment.

Mechanics and maintenance teams needing larger holes

These bits suit professionals who need to drill diameters beyond the capacity of a standard 3/8-inch chuck while using a common 1/2-inch drill. The reduced shank allows the larger cutting diameter to fit the tool holder without a specialised chuck. Users who require a split-point tip for self-centring on hard metals or a different point angle for specialised alloys should evaluate alternative bit designs.

118-degree point angle for general drilling

The 118-degree point angle is the primary specification that determines how the bit engages the workpiece. It delivers reliable performance in mild steel, cast iron, wood and plastic where a standard point is adequate. If the application demands a flatter or steeper angle for specific materials, this geometry will not match that requirement.
