Hertel 45676285 Chucking Reamer 0.345 in Solid Carbide

Product Description

The HERTEL 45676285 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a reamer diameter of 0.345 inches, an overall length of 3.5 inches, and a flute length of 1.25 inches, this tool delivers tight-tolerance bore sizing in a compact, rigid package. The solid carbide construction provides superior hardness and wear resistance compared to high-speed steel, making it well suited for harder workpiece materials and higher-volume production runs. A bright polished finish reduces friction and helps evacuate chips cleanly during the cut. This reamer is installed and operated by machinists and tool-and-die professionals using standard drill presses, CNC machining centers, or manual lathes.

The 45676285 is appropriate for through-hole and blind-hole finishing operations in ferrous and non-ferrous metals. The straight shank design allows direct chucking in standard drill chucks, collets, and floating reamer holders without adapters. The right-hand cutting direction is compatible with conventional machine spindle rotation. Its six-flute geometry distributes cutting load evenly, improving surface finish and size consistency across high-cycle production work.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• Six straight flutes with right-hand cutting direction for smooth, consistent bore finishing
• Bright polished coating reduces cutting friction and aids chip evacuation
• Straight shank fits standard drill chucks, collets, and floating holders directly
• Compact 3.5 inch OAL suits confined-clearance setups and short-reach applications

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool accepting a straight-shank reamer with a 0.345 inch diameter cutting head.

Installation Notes

Installation and operation should be performed by a qualified machinist. Power down and lock out the machine spindle before seating or removing the tool from the chuck or collet. Ensure the shank is fully seated and the chuck or collet is torqued to the machine manufacturer's specification before cutting. Use an appropriate cutting fluid for the workpiece material to maintain tool life and achieve target surface finish.
