Value Collection SM1900024 Hand Reamer 3/8 in 6 Flutes Hss

Product Description

The VALUE COLLECTION SM1900024 is a straight-flute hand reamer designed for precision hole finishing in metalworking and mechanical assembly applications. Built from high speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent sizing and smooth surface finishes in through-holes and blind holes. The 3/8 inch diameter cutting head features 6 flutes arranged in a straight pattern, and the tool runs a 5 inch overall length with a 2.5 inch flute length. Right-hand cutting direction and a straight shank make it compatible with standard tap wrench handles and manual reaming setups. Machinists, pipefitters, and maintenance technicians reach for this tool when hand-finishing drilled holes to tight dimensional tolerances.

This hand reamer is suited for use in machine shops, maintenance facilities, and field service environments where precise hole sizing is required without power tooling. It is well-matched to ferrous and non-ferrous metals in light to medium stock removal applications. The straight flute geometry is preferred for reaming holes with keyways or interrupted surfaces, where spiral flutes could chatter or deflect. It is sold individually and is appropriate for both production and one-off finishing tasks.

Key Features

• 3/8 inch diameter with 0.3750 inch decimal measurement for precise fitment verification
• 6 straight flutes for clean, consistent material removal and smooth bore finish
• High speed steel construction for durability across ferrous and non-ferrous workpieces
• Bright uncoated finish allows easy visual inspection of cutting edge condition
• Right-hand cut with straight shank for use with standard tap wrenches or hand drivers
• 2.5 inch flute length and 5 inch OAL suitable for most standard depth through-hole applications

Compatibility

Designed as a standard hand reamer for use with tap wrench handles accepting a straight shank; sized for 3/8 inch nominal hole finishing in general metalworking and mechanical maintenance applications.

Installation Notes

Hand reamers are installed and operated by machinists or maintenance technicians using a tap wrench or similar manual driver — power driving is not recommended and risks oversize bores or broken flutes. Secure the workpiece firmly before reaming and apply a suitable cutting fluid to extend tool life and improve finish quality. Remove only light stock; hand reamers are not designed for heavy material removal from undersized holes. Inspect cutting edges before each use and replace the tool if chipping or dulling is observed.
