Product Description

The CHICAGO-LATROBE Extra Long Drill Bit (23/64", MPN 50522) is a high-speed steel extended-length drill bit with a black oxide finish, 10" overall length, and a 118° notched point. It is designed for deep-hole drilling applications requiring extended reach.

Frequently Asked Questions

What is the CHICAGO-LATROBE Extra Long Drill Bit 50522 used for?

This extra-long drill bit is designed for deep-hole drilling in metal, wood, and plastic. Its 10-inch overall length and 118° notched point allow precise entry and chip evacuation in hard-to-reach locations. Common applications include maintenance, fabrication, and production work where standard-length bits cannot reach.

What are the specifications of the CHICAGO-LATROBE 50522 drill bit?

The CHICAGO-LATROBE 50522 is a 23/64-inch (0.3594-inch) black oxide high-speed steel extra-long drill bit. It has a 10-inch overall length and a 118° notched point. The black oxide finish reduces friction and resists corrosion. This bit is suitable for general-purpose drilling in ferrous and non-ferrous materials.

Where to buy CHICAGO-LATROBE 50522 drill bits worldwide?

3G Electric supplies the CHICAGO-LATROBE 50522 extra-long drill bit to customers worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact our team to place an order or request a quote for this high-speed steel drill bit.

How to select the right extra-long drill bit for deep-hole drilling?

Choose a bit with overall length exceeding your hole depth. For metal, select high-speed steel (HSS) with a black oxide finish for heat resistance. The 118° point angle suits general-purpose drilling. Ensure the shank fits your chuck. The CHICAGO-LATROBE 50522 meets these criteria for deep-hole applications.
