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 with a standard drill chuck. The 17 mm size with a 118° split point reduces walking and improves cutting efficiency. It is ideal for industrial maintenance, fabrication, and machining applications where a larger diameter bit must fit a smaller chuck.

What are the specifications of the CLE-LINE C21178 drill bit?

The CLE-LINE C21178 is a 17 mm reduced shank drill bit with a 3-flats shank for secure chuck grip. It features a 118° split point, Black & Gold HSS construction, and a diameter of 0.6693 inches. This Silver & Deming style bit is designed for high-speed drilling in ferrous and non-ferrous materials.

How to select the right reduced shank drill bit size?

Select a reduced shank drill bit like the CLE-LINE C21178 by matching the cutting diameter to your hole size and the shank diameter to your drill chuck capacity. For a 17 mm hole, ensure your machine has sufficient torque and RPM. The 118° split point helps center the bit and reduces thrust, improving accuracy in steel and alloys.
