Value Collection SM01N0041 Chucking Reamer No. 41 Hss

Product Description

The VALUE COLLECTION SM01N0041 is a straight-flute chucking reamer designed to finish-ream wire-gauge holes to a precise 0.0960-inch diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate bores in ferrous and non-ferrous metals. The straight-cylindrical shank seats securely in drill chucks or collet holders. At 3.5 inches overall length with a 0.875-inch flute length, it is sized for light finishing work in production and maintenance environments. Four right-hand cutting flutes provide smooth material removal and good surface finish. Machinists, tool and die workers, and maintenance mechanics are the primary users of this style of reamer.

This reamer is intended for finish-reaming wire-size holes in metal workpieces where close tolerances are required. It is suited to bench drill presses, CNC machining centers, and manual knee mills operating at appropriate speeds for HSS tooling. Typical applications include sizing holes for pins, dowels, and close-tolerance fasteners in light-to-medium production runs. The No. 41 wire gauge designation makes it a direct selection when working from wire-gauge drill charts in maintenance, repair, and fabrication shops.

Key Features

• No. 41 wire-gauge diameter: 0.0960 inches for precision finish reaming
• High-speed steel (HSS) construction for durability in ferrous and non-ferrous materials
• 4 straight right-hand flutes for smooth cutting action and good hole finish
• Bright, uncoated finish — ready to use without additional prep
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Compact 3.5-inch OAL suited to close-clearance fixturing and short setups

Compatibility

Designed as a standard wire-gauge chucking reamer for use in any machine tool spindle or drill chuck that accepts a straight-cylindrical shank of the corresponding diameter.

Installation Notes

Chucking reamers are installed by machinists and tool operators — power down and lock out the machine spindle before changing tooling. Secure the straight shank fully in the chuck or collet and verify runout before cutting. Use a cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Always ream in the cutting direction only; reversing a reamer under power can damage the cutting edges.
