Cleveland C72145 Jobber Length Drill Bit Wire 45 Hss

Product Description

The CLEVELAND C72145 is a jobber-length drill bit sized to wire gauge 45 (0.0820 inches), ground from high speed steel with a bright uncoated finish. It features a standard 118-degree split point with web thinning for improved penetration and reduced walking on entry. The spiral flute geometry is a regular right-hand configuration with a 4xD flute-to-diameter ratio, producing clean chip evacuation in a wide range of workpiece materials. With an overall length of 2.125 inches and a straight-cylindrical shank, this bit seats directly in standard drill chucks without adapters. It is installed and used by machinists, maintenance technicians, and metalworking tradespeople.

This bit is suited for general-purpose drilling in metal, wood, and plastics in both production and maintenance applications. The 2002G series targets everyday drilling tasks where a reliable, single-use or limited-reuse bit is preferred over a premium-coated option. The 0.0820-inch diameter makes it a common choice for tap-drill operations, pilot holes, and small-diameter through-holes in light fabrication and repair work. It fits standard keyed and keyless chucks used on bench drill presses, hand drills, and CNC machines with appropriate collet adapters.

Key Features

• Wire size 45 diameter: 0.0820 inches, with a tolerance of -0.0005 to 0.0000 inches for consistent hole sizing
• 118-degree standard point angle with web thinning reduces thrust and improves self-centering
• High speed steel construction provides hardness and wear resistance for general-purpose metal drilling
• Bright uncoated finish allows easy visual inspection of cutting edge condition
• Straight-cylindrical shank (0.0820 inches diameter) seats in standard drill chucks without adapters
• Meets ASME B94.11M and DIN 338 standards for jobber-length drill geometry

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard keyed and keyless drill chucks accepting straight-cylindrical shanks of 0.0820 inches diameter.

Installation Notes

Secure the shank fully in the chuck before drilling and verify chuck key is removed before powering the machine. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Use cutting fluid or lubricant when drilling ferrous metals to extend cutting edge life. Inspect the cutting edges before each use and replace the bit if chipping, dullness, or discoloration from overheating is present.
