Hertel 72036510 Chucking Reamer 0.651 in Hss 8 Flute

Product Description

The HERTEL 72036510 is a high-speed steel (HSS) chucking reamer designed to finish-ream holes to a precise 0.6510-inch diameter. With an overall length of 9 inches and a 2.25-inch straight flute length, this tool delivers accurate, repeatable sizing in through-holes and blind-hole applications. The straight-cylindrical shank mounts directly in standard drill chucks or floating holders. An 8-flute configuration distributes cutting load evenly, reducing chatter and improving surface finish in medium to hard ferrous and non-ferrous materials. The bright, uncoated finish makes it well-suited for use with cutting fluids in general-purpose machining environments.

This chucking reamer is used in machine shop and production environments where hole tolerances demand more precision than a drill alone can provide. Typical applications include finishing pre-drilled or bored holes in steel, cast iron, aluminum, and similar machinable materials. It is driven by a drill press, lathe, or CNC machining center and is intended for use by machinists and tool-and-die professionals working to close-tolerance print dimensions.

Key Features

• 0.6510-inch reamer diameter for precise hole finishing
• HSS construction provides toughness across a wide range of work materials
• 8-flute straight design reduces chatter and improves surface finish
• 9-inch overall length accommodates extended-reach applications
• Straight-cylindrical shank compatible with standard drill chucks and floating holders
• Bright/uncoated finish performs well with cutting fluid lubrication
• Right-hand cutting direction for standard spindle rotation

Compatibility

Designed as an OEM-style replacement or standard-production chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with standard straight-shank toolholders or floating reamer holders.

Installation Notes

Chucking reamers should be installed by qualified machinists. Always power down and lock out the machine spindle before changing tooling. Use a floating holder where possible to allow the reamer to self-align with the pre-drilled hole and avoid bell-mouthing. Apply cutting fluid appropriate to the workpiece material throughout the reaming operation.
