13/64" Carbide-Tipped Jobber Drill Bit
This 13/64 inch carbide-tipped jobber drill bit is built for drilling tough materials such as hardened steel, cast iron and abrasive alloys. The carbide tip resists wear far longer than standard high-speed steel, making it a practical choice for maintenance shops and production environments where tool life matters.
Practical limits of the jobber length format
Jobber length geometry fixes the flute at 2-7/16 inches and the overall length at 3-5/8 inches, so reach is restricted to shallow holes and through-holes in thin workpieces. The straight shank requires a secure chuck grip; run-out or insufficient clamping torque will damage the brittle carbide edge. The fixed 13/64 inch diameter means the bit cannot be used for larger clearance holes or reaming operations.

Questions about this item
Should I choose the 13/64in bit or a different size for my job?
The 13/64in size equals .2031 decimal. Pick it when the hole diameter must match that exact figure; otherwise select the bit whose decimal equivalent matches your required hole size.
What does the .2031 decimal equivalent mean when the bit is in a drill?
It means the bit will cut a hole 0.2031 inches in diameter. The 2-7/16in flute length and 3-5/8in overall length determine how deep you can drill and whether the bit fits your chuck.
