Frequently Asked Questions

What is a CLE-LINE reduced shank drill bit used for?

A CLE-LINE reduced shank drill bit is used for drilling holes in metal, wood, and plastic when a standard drill chuck cannot accommodate a larger shank. The 3-flats shank prevents slipping in the chuck, making it ideal for industrial maintenance, fabrication, and machine shops.

What are the specifications of the CLE-LINE C21181 reduced shank drill bit?

The CLE-LINE C21181 is a reduced shank drill bit with an 18.5 mm diameter, 118° split point, and black and gold HSS construction. It features a 3-flats shank for secure chuck grip. The manufacturer part number is C21181, and it is classified as a Silver & Deming drill bit.

How to select the right CLE-LINE reduced shank drill bit for my application?

To select the right CLE-LINE reduced shank drill bit, match the bit diameter to your hole size and ensure your drill chuck can accept the reduced shank. For metal drilling, use cutting fluid and a slow speed. The 118° split point reduces walking, improving accuracy in hard materials.
