Value Collection SM01N0042 Chucking Reamer No. 42 Hss

Product Description

The VALUE COLLECTION SM01N0042 is a straight-flute chucking reamer ground to a No. 42 wire gauge diameter of 0.0935 inches. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate hole finishing in ferrous and non-ferrous materials where close tolerances are required. The four-flute, right-hand cutting geometry provides smooth chip evacuation and consistent surface finish. At 3 inches overall length with a 3/4-inch flute length, this reamer is sized for short-reach applications in drill presses, CNC machining centers, and manual lathes. Machinists, toolmakers, and maintenance technicians are the primary users of this style of tool.

This chucking reamer is suited to production and maintenance environments where wire-gauge holes must be brought to final size after drilling. Typical applications include reaming pilot holes, bearing bores, and dowel-pin holes in light metalworking, automotive, and general fabrication settings. The straight-cylindrical shank seats directly in a drill chuck or collet without requiring a taper adapter, making it a straightforward drop-in for most machine setups. It is sold and packaged individually.

Key Features

• No. 42 wire size diameter — 0.0935 inches for precise hole finishing to wire-gauge tolerance
• High-speed steel (HSS) construction provides hardness and wear resistance across a range of workpiece materials
• 4-flute straight geometry supports smooth chip flow and consistent bore finish
• Right-hand cutting direction compatible with standard machine rotation
• Bright, uncoated finish — ready to use or accept an aftermarket coating as needed
• Straight-cylindrical shank fits directly into drill chucks and collet holders without adapters

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with a drill chuck or collet capable of holding a straight-cylindrical shank at the tool diameter specified.

Installation Notes

Chucking reamers should be installed by a qualified machinist following standard shop safety procedures. Power down and lock out the machine before changing tooling. Secure the straight-cylindrical shank firmly in a drill chuck or collet and verify runout with a dial indicator before cutting. Always ream at reduced speed and with appropriate cutting fluid compared to drilling — do not attempt to remove excessive stock with a reamer, as it is a finishing tool.
