Frequently Asked Questions

What is a CLE-LINE left-hand cobalt drill bit used for?

A CLE-LINE left-hand drill bit is designed for drilling in reverse rotation to extract broken bolts or screws. The cobalt construction handles hardened materials, and the 135° split point reduces walking. Common in automotive repair and industrial maintenance.

What are the specifications of the CLE-LINE C30512 drill bit?

The CLE-LINE C30512 is a 3/16" (0.1875 inch) mechanics-length drill bit with a 135° split point. It features a straw/bronze cobalt finish and is left-hand cutting. The cobalt alloy provides heat resistance for drilling tough metals.

Where to buy CLE-LINE C30512 drill bits worldwide?

3G Electric supplies CLE-LINE C30512 left-hand cobalt drill bits worldwide. As a global industrial distributor since 1990, we handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time.

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

Choose a left-hand bit like the CLE-LINE C30512 that matches the broken fastener's diameter. The 135° split point helps start accurately without a center punch. Cobalt material withstands the heat of drilling hardened steel. Always use reverse rotation at low RPM.
