Hertel 79889457 Chucking Reamer 0.13 in Solid Carbide

Product Description

The HERTEL 79889457 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. With a reamer diameter of 0.13 inches and a tight diameter tolerance of 0.0000 to 0.0002 inches, this tool delivers accurate, consistent bore sizing in production and jobsite environments. The straight flute geometry and right-hand cut make it well suited for through-hole reaming in a range of ferrous and non-ferrous materials. At 2.5 inches overall length with a 0.75-inch flute length, it fits standard chucking setups on drill presses, CNC machining centers, and manual lathes. Machinists and tool-and-die professionals are the primary users of this type of reamer.

This chucking reamer is used in applications where hole diameter accuracy and surface finish are critical. The solid carbide construction provides rigidity and wear resistance, making it appropriate for short-run and high-volume production work alike. The bright, uncoated finish keeps the tool suitable for use with a wide range of cutting fluids without coating compatibility concerns. The straight cylindrical shank seats securely in collets and drill chucks without modification.

Key Features

• Solid carbide construction for rigidity and extended tool life
• Diameter tolerance of 0.0000 to 0.0002 inches for precision bore finishing
• 4 straight flutes with right-hand cut for smooth, consistent material removal
• Bright, uncoated finish compatible with most cutting fluids
• Straight cylindrical shank for direct mounting in collets and drill chucks
• Compact 2.5-inch OAL suits close-clearance chucking setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet systems that accept a straight cylindrical shank at 0.13 inches diameter.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist familiar with proper speeds, feeds, and cutting fluid selection for carbide tooling. Secure the straight shank fully in the collet or chuck before powering the machine, and verify runout with a dial indicator where tolerances are critical. Carbide tooling is brittle and should not be subjected to interrupted cuts or excessive lateral loading. Always bring the spindle to a full stop before removing or adjusting the tool.
