Chicago-Latrobe 44224 Jobber Drill Bit
This Chicago-Latrobe 44224 drill bit is a general-purpose cutting tool for creating 3/8 inch holes in metal, wood and plastic. It is aimed at professional tradespeople and maintenance technicians who need a reliable high-speed steel bit for everyday drilling tasks.
Installing and using the 118 degree point
The 118 degree conventional point centres easily on flat surfaces without a pilot hole, making it straightforward to start in a drill press or hand drill. The bright uncoated finish can grab in sticky materials such as aluminium or soft steel if cutting fluid is not used, and the lack of coolant holes means heat builds up quickly in deep holes.
Limits of the jobber length standard
Jobber length provides a standard flute and overall length for the 0.3750 inch diameter, which suits most bench and portable drilling jobs. The fixed geometry prevents use in very deep holes where chip evacuation becomes difficult, and the high-speed steel material loses hardness faster than cobalt or carbide when drilling hardened alloys.

Questions about this item
How can I verify the 118-degree point angle is cutting correctly after I start drilling?
A properly sharpened 118-degree conventional point should centre itself without walking and produce consistent chips in steel.
Does the 44224 bit come in a pack or do I need to buy a set separately?
The 44224 is supplied as a single 3/8-inch jobber-length bit; multi-bit sets are sold separately.
When should I choose the 0.3750-inch bright finish version over a coated alternative?
Choose the bright high-speed steel version for general-purpose drilling in mild steel where coating wear is not a concern.
