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.

Questions about this item
Will the 1/2 reduced shank on the C17049 fit the chuck of my older 1/2 inch drill press?
The 1/2 reduced shank is designed to fit standard 1/2 inch chucks found on many older drill presses and hand drills.
How can I verify the 118 degree point angle is correct after I receive the bit?
The 118 degree point angle is a standard geometry for general-purpose drilling; you can confirm it visually against a drill point gauge.
Does the C17049 come with a case or just the single 51/64 inch bit?
The product is supplied as a single Silver & Deming drill bit; no case or additional accessories are included.
