Chicago-Latrobe 7/16 in Jobber Drill Bit
This Chicago-Latrobe jobber drill bit measures 7/16 inch with a 135-degree split point for accurate starts. It is made from high-speed steel with a bright uncoated finish. The fractional size suits general-purpose drilling in metal, wood and plastic. Model 41028 is supplied new for professional and DIY use.
Sustained drilling performance
The split-point geometry reduces walking and lowers thrust pressure during extended cuts. High-speed steel construction maintains edge life when feed rates are kept steady. The bright finish offers no heat-barrier coating, so coolant or periodic withdrawal is needed in deep holes. It is not suited for production runs that demand coated or carbide tooling.

Questions about this item
How much heat does the 135° split point generate when drilling all day?
The 135° split point reduces thrust and friction, so heat build-up stays lower than standard points during extended drilling in steel.
What shank size must my drill chuck accept for the 7/16 in bit?
The jobber-length bit has a 7/16 in shank, so your chuck must open to at least 0.4375 in to grip it securely.
