Value Collection SM0400870 Chucking Reamer 0.0870 in Hss

Product Description

The VALUE COLLECTION SM0400870 is a chucking reamer designed to finish-ream drilled or bored holes to a precise 0.0870-inch diameter. Machined from high-speed steel (HSS), it delivers the hardness and wear resistance needed for accurate sizing in steel, aluminum, and similar workpiece materials. The straight-flute, 4-flute geometry provides clean cutting action and easy chip clearance in through-holes. The bright, uncoated finish keeps the tool ready to use out of the box with no additional prep. Right-hand cutting direction suits standard drill press and CNC spindle rotation. This reamer is a standard tool for machinists and tool-and-die professionals requiring tight bore tolerances.

This chucking reamer is suited for machine-shop and production environments where precision hole finishing is required. It mounts in a drill chuck, collet, or floating reamer holder on a drill press, lathe, or machining center. The straight-cylindrical shank provides secure grip across a wide range of standard holding systems. Typical applications include finish-reaming pilot holes, dowel pin holes, and bearing bores in both prototype and production runs. It is appropriate for use in light-to-medium-duty material removal where dimensional accuracy is the primary requirement.

Installation Notes

A licensed machinist or qualified toolroom technician should install and operate this reamer in a properly secured machine spindle. Ensure the workpiece is firmly fixtured and the machine is at a full stop before mounting or removing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy. Follow all applicable shop safety procedures and machine-guarding requirements during operation.
