Value Collection SM0407390 Chucking Reamer Hss 0.7390 in

Product Description

The VALUE COLLECTION SM0407390 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.7390-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing in ferrous and non-ferrous materials. The straight-cylindrical shank seats cleanly in a drill chuck or collet holder. With a 9.5-inch overall length and a 2.5-inch flute length, it provides adequate reach for through-holes in standard workpiece thicknesses. Right-hand cutting geometry is standard. Machinists and tool-and-die technicians use this type of reamer to bring a drilled hole to final dimensional tolerance with a smooth surface finish.

This chucking reamer is suited for use in manual drill presses, milling machines, and CNC lathes or machining centers where a precise, straight-cylindrical bore finish is required. Applications include fixture plates, bearing bores, bushing installations, and any through-hole or blind-hole application calling for a 0.7390-inch finished diameter. It is appropriate for job shops, maintenance facilities, and production environments handling light to medium material removal on the final pass.

Key Features

• 0.7390-inch finished bore diameter for tight-tolerance hole sizing
• High-speed steel (HSS) construction provides toughness and wear resistance across a range of workpiece materials
• Straight flute geometry reduces chatter and is well-suited for through-hole reaming
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• Right-hand cutting direction matches conventional spindle rotation

Compatibility

Designed as a standard chucking reamer for use in any machine tool spindle accepting a straight-cylindrical shank of the corresponding diameter, including drill chucks and ER-style collet holders.

Installation Notes

Chucking reamers are installed by licensed machinists or qualified shop personnel. Always bring the spindle to a complete stop and confirm the machine is locked out before loading or removing the tool. Secure the shank fully in the chuck or collet and verify runout before cutting. Apply an appropriate cutting fluid for the workpiece material, and take light finishing passes only — chucking reamers are not designed for heavy stock removal.
