Cleveland C71109 Jobber Length Drill Bit Wire 9 Hss

Product Description

The CLEVELAND C71109 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with an oxide coating for added lubricity and corrosion resistance, it carries a wire size designation of 9, corresponding to a decimal diameter of 0.1960 inches. The 118-degree standard point angle makes it well suited for a wide range of common workpiece materials. With an overall length of 3.625 inches and a flute length of 2.4375 inches, this bit fits standard drill chucks and magnetic drill presses used daily in the trades. Machinists, pipefitters, electricians, and HVAC technicians reach for jobber-length bits when drilling clearance holes, pilot holes, and conduit knockouts on the job site or in the shop.

This bit is suited for light to medium-duty drilling in ferrous and non-ferrous metals, plastics, wood, and composite materials. The 4xD flute-to-diameter ratio provides adequate chip clearance during short-hole drilling operations. Its straight cylindrical shank with a diameter of 0.1960 inches fits standard three-jaw drill chucks without an adapter. The Series 2001G designation places it within a general-purpose catalog line intended for production and maintenance drilling where consistent dimensional accuracy is required. It is packaged as a single unit, making it convenient for restocking individual sizes in a shop kit or tool crib.

Key Features

• Wire size 9 with a decimal diameter of 0.1960 inches for precise hole sizing
• 118-degree standard point angle with web-thinned, tapered web geometry for easier starting
• High speed steel construction rated for general-purpose cutting in common metals and plastics
• Oxide finish reduces friction and provides light corrosion resistance during storage and use
• Regular spiral, right-hand cut with 2 flutes for efficient chip evacuation in short-hole applications
• Meets ASME B94.11M and DIN 338 standards for jobber-length drill bit dimensions and tolerances

Compatibility

Designed as an OEM-style replacement or direct stock bit for general-purpose drilling applications requiring a wire size 9 jobber-length drill; fits any standard three-jaw drill chuck accepting a 0.1960-inch straight cylindrical shank.

Installation Notes

Secure the shank fully in the drill chuck and verify the bit runs true before beginning a cut. Always wear appropriate eye protection and secure the workpiece before drilling. Replace bits showing chipping, burning, or loss of cutting geometry rather than attempting to redress them without proper grinding equipment. Diameter tolerance for this bit runs from -0.0007 to 0.0000 inches, so verify fit when drilling precision clearance holes.
