Cleveland C72030 Jobber Length Drill Bit 15/32 in Hss

Product Description

The CLEVELAND C72030 is a jobber-length twist drill bit designed for general-purpose drilling in a wide range of materials. Ground from high speed steel (HSS) with a bright, uncoated finish, this bit features a 118-degree standard point angle and a web-thinned, tapered web for easier penetration and reduced thrust. The straight-cylindrical shank measures 0.4688 inches in diameter, matching the 15/32-inch cutting diameter exactly for positive chuck grip. With an overall length of 5.75 inches and a flute length of 4.3125 inches, the C72030 provides the reach-to-diameter ratio typical of jobber-length tooling. It is installed by machinists, maintenance technicians, pipefitters, and HVAC-plumbing tradespeople working with drill presses, lathes, or handheld power tools.

The C72030 is suited for production and maintenance drilling in ferrous and non-ferrous metals, plastics, and composite materials. Its regular spiral and two-flute geometry promote efficient chip evacuation in a broad range of workpiece materials. The general-purpose grade and ASME B94.11M and DIN 338 compliance make it a standard fit for shop floor, field service, and light industrial applications where a reliable, mid-size fractional bit is needed without specialty coatings or coolant-through capability.

Key Features

• 15/32 inch (0.4688 inch) cutting diameter with diameter tolerance of -0.0010 to 0.0000 inches for consistent hole sizing

• High speed steel construction — suitable for ferrous metals, non-ferrous metals, and plastics
• Bright, uncoated finish allows easy visual inspection for wear and regrinding
• Regular spiral, two-flute design promotes efficient chip clearing at jobber length
• Straight-cylindrical shank fits standard drill chucks without adapter; right-hand cut
• Meets ASME B94.11M and DIN 338 standards

Compatibility

Designed as an OEM-style general-purpose jobber drill for use in standard keyed or keyless drill chucks accepting a straight-cylindrical shank up to 0.4688 inches in diameter; part of Cleveland Series 2002G fractional drill assortments.

Installation Notes

Install in a properly sized drill chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent rotation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend tool life and maintain hole-size tolerance. Inspect the cutting edges before each use; a dull bit increases thrust load and can cause workpiece damage or drill breakage.
