Hertel 83247114 Chucking Reamer Wire 70 0.0280 in Solid Carbide

Product Description

The HERTEL 83247114 is a solid carbide chucking reamer in wire gauge size 70, ground to a decimal diameter of 0.0280 inches with a tolerance of 0.0000 to 0.0002 inches. It is designed for precision hole finishing in metalworking applications where tight dimensional control is required. The four-flute straight configuration provides smooth chip evacuation and consistent finish quality. With an overall length of 1.5 inches and a flute length of 0.25 inches, this reamer is suited for shallow, close-tolerance bores. The bright, uncoated solid carbide construction delivers hardness and rigidity for accurate sizing in production and maintenance machining environments. Licensed machinists and tool and die professionals are the primary installers.

This reamer fits into CNC machining centers, drill presses, and manual machines equipped with a collet or drill chuck accepting a straight cylindrical shank. It is intended for finishing pre-drilled or bored holes to wire gauge size 70 in ferrous and non-ferrous metals, as well as some engineering plastics. Typical use cases include precision instrument components, small-bore hydraulic and pneumatic fittings, and tooling fixtures where hole size repeatability is critical. Right-hand cutting direction is standard for conventional clockwise-rotating spindles.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• Wire gauge size 70 with 0.0280 inch decimal diameter
• Tight diameter tolerance of 0.0000 to 0.0002 inches for close-fit bore finishing
• Four straight flutes for smooth chip flow and consistent surface finish
• Bright uncoated finish suitable for a broad range of work materials
• Straight cylindrical shank for use in standard collets and drill chucks

Compatibility

Designed as an OEM-style chucking reamer for use in any machine spindle or chuck accepting a straight cylindrical shank at this diameter range; compatible with standard collet systems sized for small-diameter tooling.

Installation Notes

Installation and use should be performed by a qualified machinist. Secure the reamer in a properly sized collet or drill chuck and verify runout before cutting. Always bring the workpiece hole to the correct pre-reamed diameter before using this tool, as reaming stock removal is minimal by design. Cutting fluid appropriate for the work material is recommended to maintain tool life and bore finish quality.
