Hertel 72025505 Chucking Reamer 0.2550 in Hss 6 Flute

Product Description

The HERTEL 72025505 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal. With a 0.2550 inch diameter and a 6 inch overall length, this reamer delivers tight-tolerance sizing in drilled or bored holes. It features six straight flutes with a bright, uncoated finish and cuts in a right-hand direction. The straight-cylindrical shank is compatible with standard drill chucks and collet holders. Machinists and toolroom professionals use this type of reamer to bring undersized holes to accurate final dimensions in production and maintenance applications.

This chucking reamer is suited for use in drill presses, lathes, and CNC machining centers where repeatable hole sizing is required. The 1.5 inch flute length is appropriate for through-holes and shallow blind-hole finishing in ferrous and non-ferrous materials. The HSS construction handles moderate cutting speeds and is a practical choice for job shop and general manufacturing environments where carbide is not required.

Key Features

• 0.2550 inch reamer diameter for precise hole finishing within the 0.2500 to 0.2999 inch range
• Six straight flutes for smooth, consistent material removal
• Right-hand cutting direction for standard rotation in conventional machine setups
• Bright, uncoated HSS construction suitable for a wide range of workpiece materials
• Straight-cylindrical shank for direct chuck or collet mounting
• 6 inch overall length with a 1.5 inch flute length for shallow to moderate depth applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, and machining centers that accept a straight-cylindrical shank toolholder or drill chuck.

Installation Notes

This reamer is installed by a machinist or toolroom technician into a drill chuck or collet holder sized for the straight-cylindrical shank diameter. Ensure the workpiece is securely fixtured and the spindle is aligned with the pre-drilled or bored hole before engaging the reamer. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never use a reamer to remove excessive stock; the hole should be pre-sized close to final dimension before reaming.
