Cleveland C71145 Jobber Drill Bit Wire 45 0.082 in Hss

Product Description

The CLEVELAND C71145 is a jobber-length twist drill bit in wire gauge size 45, with a decimal diameter of 0.0820 inches. Built from high speed steel with an oxide coating, this bit is designed for general-purpose drilling in metal, wood, and plastics. It features a 118-degree standard drill point angle, a two-flute regular spiral configuration, and a web-thinned tapered web for improved chip evacuation and reduced thrust during entry. The straight-cylindrical shank provides secure, concentric seating in standard drill chucks. This bit is sold individually and is well suited for machinists, maintenance technicians, and fabricators working with small-diameter holes in light to medium materials.

The C71145 is a general-purpose tool intended for bench drill presses, hand drills, and CNC drilling operations where a wire gauge 45 diameter is required. Its 2.125-inch overall length and 1.125-inch flute length make it appropriate for shallow to moderate depth holes in production and repair environments. The right-hand cut and standard point geometry suit it for a wide range of materials encountered in everyday machining and assembly work. It is built to ASME B94.11M and DIN 338 standards, making it a recognized specification-grade bit for shop and field use.

Key Features

• High speed steel construction with oxide coating for wear resistance and corrosion protection
• 118-degree standard point angle for general-purpose entry in common materials
• Web-thinned tapered web reduces cutting resistance and improves chip flow
• Two-flute regular spiral design with right-hand cut for efficient material removal
• Meets ASME B94.11M and DIN 338 standards for dimensional accuracy and performance

Compatibility

Designed for use in standard drill chucks accepting a 0.0820-inch straight-cylindrical shank. General-purpose fitment for bench drill presses, hand-held power drills, and CNC spindles operating in the 0.0500 to 0.1000-inch diameter range per the Series 2001G specification.

Installation Notes

Secure the straight-cylindrical shank fully in the chuck and verify runout before drilling. Always use the appropriate cutting speed for the workpiece material to avoid overheating and premature dulling of the high speed steel. Wear proper eye protection and ensure the workpiece is firmly clamped before starting the spindle. This product is sold in a minimum order quantity of 12 units.
