Value Collection SM1900042 Hand Reamer 21/32 in 8 Flutes Hss

Product Description

The VALUE COLLECTION SM1900042 is a straight-flute hand reamer designed for precision hole finishing in metal fabrication, maintenance, and mechanical assembly applications. Built from high speed steel with a bright uncoated finish, this reamer delivers consistent cutting performance for sizing and smoothing pre-drilled holes to a final diameter of 21/32 inch (0.6562 inch decimal). The 8-flute configuration distributes cutting load evenly across the bore, reducing chatter and improving surface finish. With a flute length of 3-11/16 inches and a straight shank, it seats reliably in a standard tap wrench or reamer handle for controlled hand operation.

This hand reamer is suited for tool and die shops, general machine shops, maintenance and repair operations, and field service work where hand-reaming is required to bring a drilled hole to final size or clean up an existing bore. The straight flute design works well in through-holes and is a standard choice for ferrous and non-ferrous metals. Its compact overall length of 7-3/8 inches makes it manageable in benchtop and hand-held setups without a machine spindle.

Key Features

• 21/32 inch (0.6562 inch) reamer diameter for precise hole finishing
• 8 straight flutes distribute cutting force and improve bore finish
• High speed steel construction provides wear resistance for general metalworking
• Bright uncoated finish for easy wear monitoring during service
• Right-hand cutting direction compatible with standard tap wrench operation
• Straight shank design for straightforward chuck or wrench mounting

Compatibility

Designed as a general-purpose hand reamer for use with standard tap wrenches and reamer handles accepting a straight shank. Suitable for ferrous and non-ferrous materials in maintenance, fabrication, and machining applications requiring a 21/32 inch finished bore diameter.

Installation Notes

This tool is intended for hand operation by a machinist or skilled tradesperson using a tap wrench or adjustable reamer handle. Always secure the workpiece firmly before reaming and apply cutting fluid appropriate to the workpiece material to extend tool life and improve finish quality. Feed the reamer in the cutting direction only — never rotate in reverse, as back-cutting damages the flutes. Follow applicable shop safety practices including eye protection and proper workholding.
