17 mm Jobber Drill Bit
The Chicago-Latrobe 47377 is a general-purpose jobber length drill bit sized at 17 mm. It is designed for machinists and maintenance technicians who need a reliable high-speed steel tool for everyday drilling tasks. The conventional point geometry suits a wide range of standard materials.
118 Degree Point Angle Limits
The 118 degree point angle provides effective centring and chip ejection in mild steel, aluminium and plastic. It is less suited to very hard alloys or deep-hole drilling where a split point or specialised geometry would reduce thrust and heat. The black oxide finish aids lubricity but does not replace cutting fluid in demanding cuts.
Capacity And Headroom At 17 mm
At 17 mm diameter the bit handles typical workshop holes up to several times its diameter in softer metals. The high-speed steel body offers good wear resistance for repetitive work, though material removal rate drops in stainless or hardened stock. The non-coolant design means chip clearance relies on periodic withdrawal in deeper holes.

Questions about this item
Which drill bit size should I select for a 17 mm hole?
The Chicago-Latrobe 47377 is manufactured with a 17 mm diameter and a decimal equivalent of .6693, so this single listing matches that exact size.
What does the 118 degree point angle mean when the bit is in a drill press?
A 118 degree conventional point centres quickly in steel and general-purpose materials without needing a pilot hole or specialised grinding.
What shank standard does this jobber bit use and what chuck capacity does it require?
The straight shank fits standard three-jaw chucks; a 17 mm capacity chuck is needed to grip the full diameter.
