Jobber Length Drill Bit 16.5 mm

This Chicago-Latrobe 47374 jobber length drill bit measures 16.5 mm with a 118 degree point angle. It is made from high speed steel with a black oxide finish. The decimal equivalent is .6496 inches. It suits general purpose drilling tasks in metal and wood.

Conventional Point With Black Oxide

The conventional point geometry provides reliable centring without a split point design. Black oxide coating reduces friction and resists corrosion during use. No coolant holes are present so the bit runs dry. The flute length follows standard jobber proportions for typical hole depths.

Check Chuck Capacity And Material

Verify your drill chuck accepts a 16.5 mm shank before ordering. Confirm the workpiece material is compatible with high speed steel and 118 degree point geometry. This bit is not designed for coolant-through applications or specialised alloy drilling.

Questions about this item

How often will the 16.5 mm high-speed steel bit need resharpening?

Resharpen when the 118-degree conventional point no longer cuts cleanly; high-speed steel can be reground multiple times before replacement is necessary.

What stops the bit first during a long drilling session?

Heat buildup at the 118-degree point dulls the cutting edges, so cutting speed drops before the black-oxide coating wears away.

Does the bit run hot or draw extra power when used continuously?

The black-oxide finish reduces friction, but sustained drilling in steel still generates noticeable heat at the 16.5 mm diameter, requiring cutting fluid or pauses.
