Value Collection SM01N0040 Chucking Reamer Size 40 Hss

Product Description

The VALUE COLLECTION SM01N0040 is a straight-flute chucking reamer designed to finish-ream wire gauge size 40 holes to a precise decimal diameter of 0.0980 inches. Built from high-speed steel (HSS) with a bright uncoated finish, it delivers consistent sizing performance on close-tolerance through-holes in light metals, plastics, and soft ferrous materials. The straight-cylindrical shank seats cleanly in standard collets or chucks. With an overall length of 3.5 inches and a flute length of 0.875 inches, this reamer suits bench drill presses, CNC machining centers, and manual toolroom work where small-diameter hole finishing is required.

This reamer is appropriate for toolroom, maintenance, and production environments requiring accurate finishing of wire-gauge holes. It is well suited for precision work in electronics enclosures, instrument panels, and mechanical assemblies where a size 40 wire gauge pilot or clearance hole must be brought to final dimension. Right-hand cutting direction works with conventional clockwise spindle rotation standard on most drill presses and milling machines.

Key Features

• Reamer diameter: 0.0980 inches (wire gauge size 40)
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 4-flute straight configuration for smooth cutting and chip evacuation in through-holes
• Bright uncoated finish - ready to use without additional treatment
• Straight-cylindrical shank compatible with standard collets and drill chucks
• Right-hand cutting direction for use with conventional clockwise spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, milling machines, and CNC machining centers equipped with a collet or drill chuck capable of holding a straight-cylindrical shank in the wire gauge size 40 diameter range (0.0500 to 0.0999 inches).

Installation Notes

Secure the straight-cylindrical shank firmly in a collet or keyless chuck before use. Confirm spindle rotation is set to right-hand (clockwise) before engaging the workpiece. Use cutting fluid appropriate for the workpiece material to extend tool life and improve finish quality. Handle HSS reamers carefully to avoid chipping the flute edges, which are susceptible to damage from drops or contact with hard surfaces.
