Value Collection 14442960113200S Chucking Reamer Hss

Product Description

The VALUE COLLECTION 14442960113200S is a straight-flute chucking reamer designed to bring bored or drilled holes to a precise finished diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer measures 11/32 inch (0.3438 inch decimal) in diameter and carries an overall length of 6 inches. The straight-cylindrical shank seats securely in a drill chuck or collet, and the right-hand spiral flutes cut smoothly in the right-hand direction. Machinists and toolroom technicians reach for this style of reamer when a hole requires tight dimensional tolerance and a clean surface finish that a drill alone cannot produce.

This chucking reamer is suited for general-purpose machine-shop and maintenance work where holes in the 0.3000 to 0.3499 inch diameter range need to be finished to size. It is run in a drill press, lathe, or CNC machining center at reduced speed and feed relative to drilling. The 1-1/2 inch flute length accommodates typical through-hole and shallow blind-hole applications in ferrous and non-ferrous materials. It ships as a single unit and is appropriate for both production and low-volume repair work.

Key Features

• HSS construction provides durability and resistance to wear at moderate cutting speeds
• Right-hand spiral flutes promote smooth cutting action and efficient chip evacuation
• Straight-cylindrical shank is compatible with standard drill chucks and collets
• Bright, uncoated finish suits a wide range of common workpiece materials
• 0.3438 inch (11/32 inch) diameter falls within the 0.3000 to 0.3499 inch reamer diameter range
• 6 inch overall length with a 1-1/2 inch flute length for controlled material removal

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and machining centers that accept a straight-cylindrical shank tooling in the 11/32 inch diameter class.

Installation Notes

Chucking reamers are installed by licensed machinists or skilled toolroom personnel. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer from the chuck or collet. Run the reamer at significantly lower RPM than a comparable drill and apply appropriate cutting fluid for the workpiece material to extend tool life and achieve the intended surface finish. Never reverse spindle direction while the reamer is engaged in the workpiece, as this will damage the cutting edges.
