Chicago-Latrobe 47271 Jobber Drill Bit
This Chicago-Latrobe 47271 jobber drill bit measures 4 mm in diameter with a decimal equivalent of 0.1575 inches. It features a conventional 118-degree point angle and is manufactured from High Speed Steel with a black oxide finish. The bit has a jobber length design and zero coolant holes.
General purpose metal drilling tasks
The 118-degree point suits general purpose drilling in metal, wood and plastic for trade professionals and DIY users. Builders who need a second bit for a different diameter or require coolant-through capability for deep holes should look at something else. The non-coolant design limits use in high-volume production drilling.
4 mm diameter with 118-degree point
The single specification that decides fit is the 4 mm drill bit size combined with the 118-degree conventional point angle. This determines the hole diameter and the cutting geometry for the intended material. Verify the required size and point angle before purchase.

Questions about this item
What does the 118-degree point angle do in a real machine?
The 118-degree point angle is a conventional geometry suited for general-purpose drilling in steel and other common materials.
What shank interface does the 4 mm drill bit use and what does it cap?
It uses a straight round shank that fits standard three-jaw chucks up to their rated capacity.
What physical dimensions determine whether the 47271 fits my drill?
The bit has a 4 mm diameter and jobber-length proportions, so it fits any chuck that accepts 4 mm round shanks.
