Value Collection 14442960253200S Chucking Reamer Hss

Product Description

The VALUE COLLECTION 14442960253200S is a high-speed steel (HSS) chucking reamer designed to produce precise, finished-diameter holes in metal workpieces. It carries a 25/32 inch (0.7812 inch decimal) cutting diameter and an overall length of 9-1/2 inches, with a 2-1/2 inch flute length that provides effective chip evacuation during through-hole and blind-hole finishing operations. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. The bright, uncoated HSS construction offers reliable performance across a wide range of ferrous and non-ferrous materials without the added cost of coated tooling. Machinists and toolroom technicians reach for this style of reamer when a drilled hole needs to be brought to a close-tolerance final diameter.

This chucking reamer is suited for manual machining centers, drill presses, lathes, and CNC equipment where a straight-cylindrical shank is preferred. The right-hand spiral flutes pull chips forward and provide smooth cutting action, making it appropriate for general-purpose reaming in mild steel, aluminum, brass, and cast iron. Typical applications include production reaming of bearing bores, pin holes, and precision clearance fits in fabrication and repair environments. It is sold as a single unit, making it practical for toolroom restocking or job-specific procurement.

Key Features

• 25/32 inch (0.7812 inch) cutting diameter for consistent finished-bore sizing
• HSS tool material provides toughness and wear resistance across common workpiece materials
• Right-hand spiral flutes promote forward chip flow and reduce chatter
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• Bright, uncoated finish allows easy visual inspection of cutting edge condition
• 9-1/2 inch overall length accommodates moderate-depth reach requirements

Compatibility

Designed as a general-purpose chucking reamer for use in any machine tool equipped to accept a straight-cylindrical shank, including drill presses, lathes, milling machines, and CNC machining centers.

Installation Notes

Chucking reamers are installed and removed by a licensed machinist or qualified toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. The shank must be seated fully and clamped securely in the chuck or collet to prevent runout, which is the leading cause of oversized or bell-mouthed holes. Always ream at appropriate speeds and feeds for the workpiece material and apply cutting fluid to extend tool life and improve finish quality.
