CHICAGO-LATROBE Left-Hand High-Speed Steel Jobber-Length Drill Bits.

Frequently Asked Questions

What is the CHICAGO-LATROBE Jobber Length Drill Bit #1 used for?

This left-hand drill bit is used for drilling holes in metal, particularly for removing broken bolts or screws. The 118° point and HSS construction suit general-purpose drilling in steel, aluminum, and other alloys. It is common in automotive repair, maintenance, and manufacturing applications.

What are the specifications of the CHICAGO-LATROBE 44471 drill bit?

The CHICAGO-LATROBE 44471 is a #1 jobber-length drill bit with a 0.2280-inch diameter, 118° point angle, and high-speed steel (HSS) construction. It features a left-hand spiral for reverse-rotation drilling. The manufacturer part number is 44471, and it is designed for precision metalworking.

Where to buy CHICAGO-LATROBE 44471 drill bits worldwide?

You can source the CHICAGO-LATROBE 44471 left-hand drill bit through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead times for this and other CHICAGO-LATROBE tooling.

How to select the correct left-hand drill bit for bolt removal?

Select a left-hand drill bit like the CHICAGO-LATROBE #1 (0.2280 inch) when drilling out broken fasteners. The reverse rotation helps extract the bolt as you drill. Use cutting oil, moderate speed, and steady pressure. Ensure the bit is sharp and properly aligned to avoid wandering.
