Cle-Line C17049 51/64 in 118 Degree Silver & Deming Drill with 1/2 Reduced Shank

Cle-Line C17049 Silver & Deming Drill

The Cle-Line C17049 is a Silver & Deming drill bit designed for machinists and maintenance technicians who need to enlarge existing holes in metal. Its 1/2 inch reduced shank fits standard drill chucks, allowing use on bench or portable drills without specialised tooling.

51/64 inch capacity and 118 degree point

The 51/64 inch cutting diameter handles medium-to-large hole enlargement in steel and cast iron where standard twist drills cannot reach. The 118 degree point angle provides reliable centring in ferrous metals but is not optimised for hard alloys or high-speed production runs where a split point or cobalt bit would last longer.

High-speed steel with black and gold finish

Manufactured from high-speed steel, the bit resists heat buildup during intermittent cutting in mild and medium-carbon steel. The black and gold surface treatment adds lubricity and corrosion resistance, extending service life in general-purpose workshop environments.
