Hertel 45675550 Chucking Reamer 0.245 in Solid Carbide

Product Description

The HERTEL 45675550 is a solid carbide chucking reamer designed to finish-ream precision holes to a 0.245-inch diameter. Solid carbide construction delivers the rigidity and wear resistance needed for consistent, accurate results in production and job-shop environments. The four-flute, straight-flute geometry provides smooth cutting action and good chip evacuation in a variety of workpiece materials. With a 3-inch overall length and a 1-inch flute length, this reamer is sized for standard short-reach applications. The bright, uncoated finish makes it well-suited for use with cutting fluids where coating adhesion is not required. Machinists and toolroom technicians are the primary users of this tool.

This chucking reamer is used in CNC machining centers, manual mills, and drill presses where a straight shank allows direct mounting in a drill chuck or collet. It is appropriate for finishing operations in metals where tight hole tolerances are required. The right-hand cutting direction is standard for conventional clockwise-spindle machines. The compact flute length suits shallow through-holes and blind holes of moderate depth in both prototype and repeat-production work.

Key Features

• Solid carbide construction for superior rigidity and extended tool life
• 0.245-inch reaming diameter for precision hole sizing
• Four straight flutes for smooth cutting and efficient chip removal
• Right-hand cut — compatible with standard clockwise-rotation spindles
• Straight shank mounts directly in a drill chuck or collet without special toolholding
• Bright, uncoated finish suitable for use with cutting fluids

Compatibility

Designed as a standard straight-shank chucking reamer for use in CNC machining centers, manual milling machines, and drill presses equipped with a drill chuck or collet capable of accepting a straight shank at the 0.245-inch diameter range.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists familiar with rotating cutting tool safety. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the tool from the chuck or collet. Secure the straight shank firmly to prevent runout, which directly affects hole-size accuracy and tool life. Always apply an appropriate cutting fluid for the workpiece material and operate within the spindle speed and feed rate ranges recommended for solid carbide reamers.
