Frequently Asked Questions

What is the CLE-LINE Taper Shank Drill Bit used for?

The CLE-LINE Taper Shank Drill Bit (C21981) is used for heavy-duty industrial drilling in metal, such as steel and cast iron. Its MT4 shank fits directly into machine spindles, making it ideal for lathes, milling machines, and drill presses requiring high torque and precision.

What are the specifications of the CLE-LINE Taper Shank Drill Bit?

The CLE-LINE Taper Shank Drill Bit (MPN C21981) has a 40 mm diameter, 118° point angle, and black oxide finish. It is made of high-speed steel (HSS) with an MT4 shank and a 1.5748 measurement. These specs ensure durability and efficient chip evacuation in industrial drilling.

Where to buy the CLE-LINE Taper Shank Drill Bit worldwide?

You can source the CLE-LINE Taper Shank Drill Bit (C21981) through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive the correct HSS taper-shank drill bit for your operations.

How to select the right taper shank drill bit for a machine?

To select the right taper shank drill bit, match the shank size (e.g., MT4) to your machine spindle's taper. Consider the hole diameter (40 mm), material (HSS for steel), and point angle (118° for general use). CLE-LINE bits like C21981 are designed for high-torque industrial drilling applications.
