Hertel 45674439 Chucking Reamer 0.0515 in Solid Carbide

Product Description

The HERTEL 45674439 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. With a reamer diameter of 0.0515 inches and an overall length of 1.5 inches, this tool is built for small-bore work where dimensional accuracy is critical. The straight flute geometry and bright polished finish reduce friction and promote clean chip evacuation. Four right-hand cutting flutes deliver consistent material removal and a smooth bore surface. Solid carbide construction provides the rigidity and wear resistance required for production runs in ferrous and non-ferrous materials.

This reamer is suited for CNC and manual lathe or drill press applications where a straight shank tool is required for collet or drill chuck mounting. It is used in machine shops, tool rooms, and precision manufacturing environments. The 0.375-inch flute length makes it appropriate for shallow through-holes and blind holes in the small-diameter range. Machinists and tool-and-die technicians are the typical end users for this style of reamer.

Key Features

• 0.0515-inch reamer diameter for small-bore precision finishing
• Solid carbide construction for rigidity and extended tool life
• 4 straight flutes with right-hand cutting direction
• Bright polished finish reduces friction and improves surface finish
• Straight shank compatible with collets and standard drill chucks
• Compact 1.5-inch OAL suits tight-clearance setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank collet chucks and drill chucks accepting tools in the 0.0500 to 0.0999-inch diameter range.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist familiar with precision hole-finishing operations. Ensure the workpiece is securely fixtured and the spindle is at the correct RPM for carbide tooling before engaging the cut. Use appropriate cutting fluid to extend tool life and improve surface finish. Inspect the shank seating in the chuck or collet before use to prevent runout.
