Value Collection SM0400845 Chucking Reamer 0.0845 in Hss

Product Description

The VALUE COLLECTION SM0400845 is a chucking reamer designed to finish-ream precision holes to a nominal diameter of 0.0845 inches. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers the hardness and wear resistance required for accurate hole sizing in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in a drill press chuck, CNC turret, or lathe tailstock. With 4 straight flutes and right-hand cutting direction, this reamer produces clean, consistent bore finishes in production and maintenance machining environments.

This reamer falls within the 0.0500 to 0.0999 inch diameter range, making it suited for small-bore finish reaming applications in precision machining, toolroom work, and light manufacturing. Typical use cases include final sizing of dowel pin holes, clearance holes for small fasteners, and bearing seat preparation where tight tolerances are required. It is sold individually and is appropriate for both manual machine operation and CNC-assisted setups where a straight-shank tool holder is in use.

Key Features

• 0.0845 inch reamer diameter for small-bore precision hole finishing
• High-speed steel (HSS) construction for hardness and wear resistance across a range of workpiece materials
• Straight-cylindrical shank for secure seating in standard drill chucks and tool holders
• 4 straight flutes for efficient chip evacuation and consistent surface finish
• Right-hand cutting direction compatible with standard spindle rotation
• Bright, uncoated finish — no additional coating buildup that could affect dimensional accuracy

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for any machine setup accepting a straight-cylindrical shank in the 0.0845 inch nominal diameter range.

Installation Notes

Installation is performed by machinists using a drill press, lathe, or CNC machine with an appropriate straight-shank chuck or collet. Power down and lock out the machine spindle before seating or removing the reamer from the tool holder. Always use cutting fluid appropriate for the workpiece material to extend tool life and improve bore finish. Do not exceed recommended feed rates for HSS tooling in hard materials, as chucking reamers are finishing tools and are not designed for heavy stock removal.
