Chicago-Latrobe 47363 13.5 mm Drill Bit

This Chicago-Latrobe 47363 jobber drill bit measures 13.5 mm with a 118-degree conventional point angle. It is manufactured from high speed steel with a black oxide finish. The decimal equivalent is 0.5315 inches. It suits general purpose drilling tasks across various materials.

Black Oxide Finish and Conventional Point

The black oxide finish helps reduce friction and improves chip flow during operation. The 118-degree conventional point centres the bit quickly without a pilot hole. No coolant holes are present, so the bit relies on external lubrication or air cooling. The high speed steel construction resists heat buildup at standard drilling speeds.

13.5 mm Capacity for General Drilling

This bit comfortably handles 13.5 mm diameter holes in steel, cast iron and non-ferrous metals. The jobber length provides standard reach for through-holes and moderate depth drilling. It runs out when a larger diameter, extended length or coolant-through capability is required for the application.

Questions about this item

When will the 13.5 mm drill bit need resharpening or replacement?

Resharpen the 118-degree conventional point when cutting edges dull; replace the high-speed steel bit if the shank or flutes show wear or damage.

What limits continuous drilling with the 47363 bit?

Heat buildup in the high-speed steel body and chip evacuation through the flutes become the limiting factors during sustained drilling.

How much heat and noise does the 13.5 mm bit produce in all-day use?

The black oxide finish reduces friction, but extended drilling generates noticeable heat at the cutting zone and standard drilling noise levels.
