Cle-Line C17037 39/64 in Drill Bit
The Cle-Line C17037 is a silver and deming drill bit sized at 39/64 in with a 1/2 reduced shank. It is made from machining high speed steel and features a black and gold finish. The 118 degree point angle suits general purpose drilling tasks. This accessory targets machinists and maintenance technicians who need a large diameter hole in metal.
Practical limits of the 1/2 reduced shank
The reduced shank allows this 39/64 in bit to fit a standard 1/2 in drill chuck. Larger shank diameters would require a larger capacity chuck or a different tool holder. The high speed steel construction handles standard machining heat but may wear faster in abrasive or hardened materials. Users must match the drill press or hand drill torque to the bit diameter.
Installation and common issues
The bit installs by tightening the 1/2 reduced shank securely in a three-jaw chuck. Ensure the shank seats fully and the jaws grip the flat surfaces to prevent slippage. A common problem is the bit spinning in the chuck under heavy feed pressure if not clamped tightly. Dulling of the 118 degree point reduces cutting efficiency and increases required force.

Questions about this item
Is the 39/64 inch size the right choice for a 1/2 inch chuck?
Yes, the 39/64 inch bit features a 1/2 inch reduced shank designed to fit a standard 1/2 inch drill chuck.
How does the 118 degree point angle perform in metal?
The 118 degree point is a general-purpose geometry that centres quickly in mild steel and other common metals.
What does the high speed steel construction mean for durability?
High speed steel retains hardness at elevated temperatures, giving the bit good wear resistance in steel and alloy drilling.
