Value Collection SM0400790 Chucking Reamer 0.0790 in Hss

Product Description

The VALUE COLLECTION SM0400790 is a straight-shank chucking reamer designed to finish-ream drilled holes to a precise 0.0790-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance in a wide range of ferrous and non-ferrous materials. The 4-flute straight-flute geometry produces a smooth bore finish and allows efficient chip evacuation during through-hole and blind-hole reaming operations. Right-hand cutting direction makes it compatible with standard drill press and CNC spindle rotation. Machinists, tool-and-die makers, and maintenance technicians use this type of reamer to bring undersized or rough-drilled holes to finished tolerance.

This chucking reamer is suited for light-production and maintenance machining environments where small-diameter precision holes are required. The straight-cylindrical shank seats directly in standard drill chucks, collet chucks, or floating reamer holders without the need for Morse taper adapters. Typical applications include hinge-pin holes, precision pivot bores, and alignment holes in metal fixtures and assemblies. Its compact diameter places it in the 0.0500-to-0.0999-inch decimal-inch reamer range, making it appropriate for fine-detail work on small components.

Key Features

• 0.0790-inch finished bore diameter for tight-tolerance hole sizing
• High-speed steel (HSS) construction for durability across common work materials
• 4-flute straight-flute design promotes smooth finish and controlled chip flow
• Bright, uncoated finish suitable for general-purpose reaming without specialty lubricants
• Straight-cylindrical shank fits standard drill chucks and collet holders directly
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, milling machines, and CNC machining centers equipped with a standard drill chuck or collet chuck sized to accept a straight-cylindrical shank in the 0.0500-to-0.0999-inch diameter range.

Installation Notes

Secure the shank fully in the chuck or collet before beginning the reaming operation and verify concentricity to minimize runout. Always reduce spindle speed compared to drilling and apply an appropriate cutting fluid for the work material to extend tool life and improve bore finish. Do not attempt to remove excessive stock with a reamer — pre-drill the hole to within a few thousandths of the finished size before reaming. Follow applicable shop safety standards and machine guarding requirements during operation.
