Value Collection SM0407400 Chucking Reamer 0.74 in Hss

Product Description

The VALUE COLLECTION SM0407400 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.7400-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent dimensional accuracy in ferrous and non-ferrous materials. The straight-cylindrical shank seats directly in a drill chuck or collet, and the right-hand cutting direction is standard for conventional CNC and manual drill press or lathe operations. At 9.5 inches overall length with a 2.5-inch flute length, it reaches into moderately deep bores without excessive deflection. Machinists and tool-and-die technicians are the primary users.

This chucking reamer is suited for production and maintenance machining environments where a 0.7400-inch finished bore is required. Typical applications include finishing bearing seats, bushing bores, and precision clearance holes in steel, cast iron, aluminum, and brass workpieces. The straight flute geometry performs well in materials that do not tend to chatter, and the uncoated HSS construction makes the tool straightforward to resharpen in-shop when edge wear occurs.

Key Features

• 0.7400-inch reamer diameter for precise hole finishing to nominal size
• High-speed steel (HSS) construction provides good wear resistance across a range of workpiece materials
• Straight-cylindrical shank accepts standard drill chucks and collet holders
• Straight flute geometry suited for through-holes and short blind bores
• Right-hand cutting direction compatible with conventional spindle rotation
• Bright uncoated finish allows easy resharpening without coating considerations

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with standard drill chucks or collet systems accepting straight-cylindrical shanks in the 0.7000 to 0.9999-inch diameter range.

Installation Notes

A licensed machinist or qualified shop technician should install and operate this reamer. Always ensure the spindle and workpiece fixture are secured and the machine is at a safe, reduced RPM appropriate for reaming operations before engaging the cut. Use cutting fluid or appropriate lubricant to extend tool life and improve surface finish. Inspect the cutting edges for wear or chipping before each use and remove the tool from service if damage is observed.
