Product Description

The CLE-LINE Mechanics Length Drill Bit (SKU 3G-OTH-196710) is a 5/32" left-hand cobalt bit with a 135° split point and straw/bronze finish. It is designed for industrial drilling applications requiring left-hand rotation, with a diameter of 0.1563 inches.

Frequently Asked Questions

What is a CLE-LINE C30510 left-hand drill bit used for?

The CLE-LINE C30510 is a 5/32" left-hand cobalt mechanics-length drill bit with a 135° split point, designed for drilling out broken bolts or screws. The left-hand rotation helps extract fasteners by backing them out during drilling, common in automotive and industrial repair.

What are the specifications of the CLE-LINE C30510 drill bit?

The CLE-LINE C30510 is a 5/32" (0.1563") mechanics-length drill bit with a 135° split point, straw/bronze cobalt finish, and left-hand cutting direction. It is made from cobalt steel for heat resistance and durability in hard materials.

Where to buy CLE-LINE C30510 left-hand drill bits worldwide?

3G Electric supplies the CLE-LINE C30510 left-hand cobalt drill bit to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other industrial tooling needs.

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

For bolt extraction, choose a left-hand drill bit like the CLE-LINE C30510 with a 135° split point to reduce walking. Match the bit diameter to the broken fastener's minor diameter. Cobalt construction handles harder materials. Use cutting oil and slow speed to prevent breakage.
