Frequently Asked Questions
What is a CLE-LINE left-hand cobalt drill bit used for?
CLE-LINE left-hand cobalt drill bits are designed for drilling into hardened metals and for removing broken bolts or screws. The left-hand rotation helps extract fasteners during reverse drilling. The 135° split point reduces walking and improves cutting accuracy in industrial maintenance and repair applications.
What are the specifications of the CLE-LINE C30520 drill bit?
The CLE-LINE C30520 is a mechanics-length drill bit with a 5/16" (0.3125 inch) diameter. It features a 135° split point, a straw/bronze cobalt finish, and a left-hand cutting direction. This cobalt construction provides heat resistance for drilling in tough materials like stainless steel.

How to select the right left-hand drill bit for bolt extraction?
For bolt extraction, choose a left-hand cobalt drill bit like the CLE-LINE C30520. Match the bit diameter to the broken fastener's core size. Use a 135° split point for precise starting without a center punch. Apply cutting oil and drill at slow speed to avoid overheating the cobalt material.
