Hertel 45675741 Chucking Reamer 0.276 in Solid Carbide

Product Description

The HERTEL 45675741 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and toolroom applications. With a 0.276-inch cutting diameter, 6 straight flutes, and a bright polished finish, it delivers tight tolerances and smooth bore surfaces in a single pass. The straight shank makes it compatible with standard drill chucks and collet holders. At 3.25 inches overall length with a 1.125-inch flute length, it suits a range of shallow-to-medium depth reaming operations. Machinists and tool-and-die professionals rely on solid carbide construction for its hardness and wear resistance in demanding production environments.

This reamer is suited for right-hand cutting in ferrous and non-ferrous materials where dimensional accuracy and surface finish are critical. Typical applications include finish reaming of drilled or bored holes to close tolerances in components requiring precise fit, such as dowel pin locations, bearing bores, and hydraulic body passages. It performs well on CNC machining centers, manual mills, and drill presses when operated at appropriate speeds and feeds for the workpiece material.

Key Features

• 0.276-inch cutting diameter for precision hole finishing
• Solid carbide construction for superior hardness and extended tool life
• 6 straight flutes with right-hand cutting direction
• Bright polished finish reduces friction and aids chip evacuation
• Straight shank fits standard drill chucks and collet holders
• 3.25-inch overall length with 1.125-inch flute length for versatile reach

Compatibility

Designed as a standard chucking reamer for use in drill chucks, ER collets, and similar straight-shank toolholders on CNC machining centers, manual knee mills, and drill presses.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and power is locked out before mounting or removing the reamer. Secure the straight shank firmly in a properly sized collet or chuck to minimize runout. Always follow manufacturer-recommended speeds and feeds for the specific workpiece material to avoid chipping the carbide cutting edges.
