Chicago-Latrobe 46625 Jobber Length Drill Bit 25/64 in Cobalt Split Point 135°

Chicago-Latrobe 46625 Cobalt Drill Bit

This Chicago-Latrobe 46625 drill bit is a jobber length cutting tool made from cobalt steel with a straw bronze finish. It features a 25/64 inch fractional size and a decimal equivalent of .3906 inches. The 135 degree split point design allows for accurate starting without a centre punch. It is intended for professional mechanics and metalworkers drilling hard materials.

Split Point Geometry and Cobalt Material

The 135 degree split point reduces walking and lowers the thrust required to penetrate the workpiece. Cobalt construction provides increased heat resistance and hardness compared to standard high speed steel bits. The jobber length offers a standard flute and overall length ratio suitable for general purpose drilling depths. No coolant holes are present on this tool.

Suited for Hard Metal Drilling Tasks

This bit suits users drilling stainless steel, cast iron or other tough alloys where cobalt heat resistance is beneficial. The fractional 25/64 inch size fits specific fastener or tap drill requirements. Buyers needing coolant through capability or a different point angle should look at alternative designs. Those requiring metric sizes or coated finishes will need other options.
