Value Collection 14442960073200S Chucking Reamer 7/32 in Hss

Product Description

The VALUE COLLECTION 14442960073200S is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 7/32 inch (0.2188 inch decimal) diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent sizing in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats directly in a drill chuck or collet, and the right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole operations. Overall length is 5 inches with a 1-1/4 inch flute length, keeping the tool rigid in light-duty reaming setups.

This chucking reamer is suited for machine shop, maintenance, and light production work where a tight hole tolerance is required after drilling. Typical applications include fixture work, jig building, dowel-pin hole finishing, and general metalworking on drill presses, CNC machining centers, and manual mills or lathes. The compact flute length is well matched to thin-stock and shallow-depth reaming passes where tool runout must be minimized.

Key Features

• 0.2188 inch (7/32 inch) nominal diameter for precision hole finishing
• High-speed steel (HSS) construction withstands moderate cutting heat and abrasion
• Right-hand spiral flutes promote smooth chip evacuation and reduce chatter
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank compatible with standard drill chucks and ER collets
• 5 inch overall length provides clearance for most standard machine setups

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, manual mills, lathes, and CNC machining centers equipped with a standard drill chuck or collet system accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed by a machinist or toolroom technician — power down and lock out the machine spindle before changing tooling. Always pre-drill the hole 0.005 to 0.015 inches undersize before reaming; attempting to remove excess stock with a reamer will accelerate wear and degrade hole finish. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect the shank and flutes for nicks or runout before chucking to avoid bell-mouthing the finished hole.
