Hertel 45675659 Chucking Reamer 0.263in Solid Carbide

Product Description

The HERTEL 45675659 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. With a 0.263-inch diameter and six straight flutes, it delivers tight-tolerance reaming in a right-hand cutting direction. The bright polished finish reduces friction and aids chip evacuation. At 3.25 inches overall length with a 1.125-inch flute length and straight shank, this reamer is suited for use in drill presses, CNC machining centers, and other chucking setups where dimensional accuracy and surface finish are the primary requirements. Machinists and tool-and-die professionals are the primary users.

This reamer is intended for through-hole and blind-hole finishing operations where the nominal target diameter falls in the 0.250 to 0.299-inch range. The solid carbide construction supports use in harder workpiece materials and higher spindle speeds compared to HSS alternatives. The straight shank allows direct mounting in standard chucks or collets without an adapter. Typical applications include production machining environments where repeatable hole sizing is required for press fits, dowel pin bores, or bearing seats.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• Six straight flutes with right-hand cutting direction for smooth, controlled material removal
• Bright polished finish reduces built-up edge and aids chip flow
• Straight shank for direct mounting in standard chucks or collets
• 0.263-inch diameter targets the 0.250 to 0.299-inch reamer diameter range
• Compact 3.25-inch OAL suits confined-clearance setups

Compatibility

Designed as an OEM-style precision chucking reamer suitable for use in standard drill press chucks, CNC machining center collets, and lathe tailstock setups that accept straight-shank tooling in the 0.250 to 0.299-inch diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations and machine tool safety. Secure the straight shank firmly in the chuck or collet before operation and verify runout with an indicator before cutting. Always reduce spindle speed and use appropriate cutting fluid for the workpiece material when reaming to achieve target surface finish and diameter tolerance. Inspect flutes for wear or chipping before each use, as carbide tooling is brittle and can fracture if forced into an undersized pilot hole.
