Chicago-Latrobe 42777 Jobber Drill Bit
This Chicago-Latrobe 42777 jobber-length drill bit is built for general-purpose drilling in metal, wood and plastic. It suits maintenance technicians, metalworkers and DIY users who need a reliable high-speed steel cutting tool for everyday workshop tasks.
135 Degree Split Point Geometry
The 135-degree split point reduces walking and starts holes cleanly without a centre punch. This geometry decides whether the bit matches the material and precision you need for accurate drilling operations.
TiAlN Coated High Speed Steel
The TiAlN coating on high-speed steel resists heat and wear, extending bit life in steel and alloy work. It fits standard three-jaw chucks and frees you from frequent resharpening during repetitive drilling jobs.

Questions about this item
How does the 135-degree split point behave once the bit is chucked in a drill?
The 135-degree split point centres itself on contact, reducing walk and letting the bit start cutting immediately without a centre punch.
What does the TiAlN coating on this high-speed steel bit actually withstand in use?
TiAlN resists heat buildup and wear, allowing higher cutting speeds and longer life in steel, stainless and other tough alloys.
Will the 0.2610-inch diameter jobber-length shank fit a standard three-jaw chuck?
Yes, the straight round shank at 0.2610 inch seats securely in any drill chuck that accepts that diameter.
