Value Collection 144429602505000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602505000 is a 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 features a 0.2505-inch cutting diameter and a straight-cylindrical shank for secure chuck mounting. Six straight flutes and a right-hand cutting direction deliver clean, consistent material removal in a range of ferrous and non-ferrous workpiece materials. Machinists and tool-and-die technicians reach for chucking reamers when hole tolerances demand accuracy beyond what a drill alone can achieve.

This reamer is suited for machine-based reaming operations on drill presses, lathes, and milling machines. The straight-cylindrical shank seats directly in standard drill chucks or collet holders without modification. At 0.2505 inches, the cutting diameter falls within the 0.2500 to 0.2999-inch decimal inch range, making it the appropriate selection when a finished hole close to 1/4 inch is required and a standard 0.2500-inch reamer would leave insufficient wall stock for press or locating fits.

Key Features

• 0.2505-inch cutting diameter for close-tolerance finishing of near-1/4-inch holes
• HSS construction provides toughness and wear resistance across a broad range of workpiece materials
• 6-flute geometry distributes cutting load evenly and promotes smooth surface finish
• Straight flutes suit through-hole and blind-hole reaming in most machine setups
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• Bright, uncoated finish — no coating thickness variation to account for in diameter calculations

Compatibility

Designed as a machine-mounted chucking reamer for use in drill presses, lathes, and milling machines equipped with a standard drill chuck or collet system accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by machinists following standard machine-shop practices. Secure the straight-cylindrical shank fully in the chuck or collet and verify runout before cutting. Always reduce spindle speed significantly compared to drilling — typical practice is to run a reamer at roughly one-half to one-third of the drilling speed for the same material, though the operator should consult applicable feeds-and-speeds references for the specific workpiece. Use cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish.
