Cleveland C72011 Jobber Drill Bit 11/64 in Hss 118 Deg

Product Description

The CLEVELAND C72011 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel (HSS) with a bright uncoated finish, this bit measures 11/64 inch (0.1719 inch) in diameter and delivers a 118-degree standard point angle for reliable center-starting on most common materials. The web-thinned, tapered web design reduces thrust and improves chip evacuation during drilling. At 3-1/4 inches overall length with a 2-1/8 inch spiral flute, it fits standard drill chucks and drill presses used in fabrication, maintenance, and light industrial work. It is sold individually with a minimum order quantity of 12 units.

The C72011 is suited for general-purpose applications in maintenance, repair, and light manufacturing environments. The right-hand spiral flute and straight cylindrical shank allow use in hand drills, drill presses, and CNC turret setups requiring a standard jobber-length bit. The 4xD flute-to-diameter ratio and regular spiral type make it appropriate for through-hole and blind-hole operations in a wide range of workpiece materials at moderate feed and speed rates.

Key Features

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard 3-jaw chucks on hand drills, drill presses, and CNC turret machines accepting straight cylindrical shanks in the 0.1500 to 0.2000 inch diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist or technician familiar with drill press or CNC setup procedures. Secure the workpiece firmly before drilling and ensure the chuck is fully tightened on the straight shank before operation. Always power down the machine and allow it to come to a complete stop before changing bits or adjusting chuck position. Do not exceed the recommended speed and feed parameters for the workpiece material and bit diameter.
