Chicago-Latrobe 70227 Jobber Drill Bit
This Chicago-Latrobe 70227 drill bit is a jobber length cutting tool made from high speed steel with a TiN coating. It features a conventional 118 degree point angle designed for general purpose drilling applications. The fractional size is 27/64 inch with a decimal equivalent of .4219 inches.
Suited for general purpose drilling tasks
This bit suits mechanics and fabricators drilling metal, wood or plastic where a standard jobber length is appropriate. It is not for buyers who need coolant through capability or a split point design for self centering. Builders requiring a different diameter or point angle should look at other options.
27/64 inch fractional diameter with 118 degree point
The defining specification is the 27/64 inch fractional diameter paired with a 118 degree conventional point angle. This combination determines the hole size and the cutting behaviour in general purpose materials. Verify these two figures match your application requirements before purchase.

Questions about this item
Will the 27/64 in jobber bit generate much heat or noise when drilling all day?
The 118-degree conventional point on this high-speed steel bit reduces cutting force, so heat build-up stays moderate and the bit runs quietly in a hand drill or press.
What shank size must my drill chuck accept for the 27/64 in bit to fit?
The bit has a straight shank matching its 27/64 in (0.4219 in) diameter, so your chuck needs to open to at least that size.
Can I use the 27/64 in TiN-coated bit in an older drill press that only takes straight-shank tools?
Yes, the straight shank on this 70227 bit fits any chuck that accepts a 27/64 in round shank, including vintage presses.
