Jobber Length Drill Bit for Heavy-Duty Use

This 5/16 inch jobber length drill bit features a 135 degree split point for accurate starting and reduced walking. It is made from High Speed Steel with a black oxide finish for durability in demanding applications. The fractional inch size suits general-purpose drilling tasks in metal and wood.

Check Chuck Capacity and Material Compatibility

Verify that your drill chuck accepts a .3125 inch shank before ordering. The bit is designed for non-coolant-through operation and has zero coolant holes. Ensure the workpiece material matches high-speed steel capabilities for best results.

High Speed Steel Construction

The HAWA material and black oxide coating resist wear and corrosion during repeated use. Split point geometry helps the bit engage quickly without a centre punch. Jobber length provides standard reach for most bench and handheld drilling jobs.

Questions about this item

Does the Chicago-Latrobe 45620 drill bit ship alone or in a set, and is a drill chuck included?

The 45620 is a single 5/16 in jobber-length bit; a compatible drill chuck is not included and must be supplied separately.

Should I choose the 135-degree split-point version or a different point angle for stainless steel?

The 135-degree split-point geometry on this high-speed steel bit reduces walking and is the recommended choice for harder materials such as stainless steel.

What does the .3125 decimal equivalent mean when I chuck this bit in my drill press?

The .3125 decimal equivalent confirms the exact 5/16 in diameter, so the bit fits a standard 5/16 in chuck capacity without undersize or oversize issues.
