Chicago-Latrobe 50619 Extra Long Drill Bit
This Chicago-Latrobe 50619 drill bit is built for tradespeople who need to reach deep into thick materials. The 5/8 inch fractional size and nine inch maximum drilling depth suit general purpose machining tasks. It targets professionals requiring extended reach without changing tools.
High Speed Steel Construction with Black Oxide
High speed steel provides the hardness needed for repetitive drilling in metal and wood. Black oxide finish reduces friction and resists corrosion during daily use. The 118 degree notched point centres quickly and the 28 degree helix clears chips efficiently. The straight shank fits standard three jaw chucks for secure mounting.
Replaces Shorter Bits for Through Drilling
This bit replaces shorter drills when holes must pass through thick plate, beam or stacked workpieces. The four times diameter length eliminates the need for extension accessories in many setups. The upgrade is worthwhile when hole depth exceeds standard jobber lengths and rigidity must be maintained. It is not for buyers who need smaller diameters or shorter overall lengths.

Questions about this item
What does the 118-degree point angle mean for drilling performance?
The 118-degree point angle provides a general-purpose cutting geometry suitable for a wide range of materials, offering good centring and chip evacuation in standard drilling applications.
What shank size does the 5/8-inch drill bit require for a secure fit?
The 5/8-inch diameter drill bit requires a chuck capacity of at least 5/8 inch to grip the shank securely during operation.
How do you install the extra-long drill bit to prevent wobble at the 9-inch depth?
Insert the shank fully into the chuck, tighten all three jaws evenly, and use a lower RPM with steady pressure to maintain alignment throughout the 9-inch drilling depth.
