Value Collection 144429602870000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602870000 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, it cuts right-hand and is sized at 0.2870 inches in diameter. The straight-cylindrical shank seats cleanly in a drill chuck or collet, making it a standard choice for machine reaming operations on the shop floor or in the field. With six flutes, it produces consistent chip evacuation and a smooth bore wall finish across a range of materials.

This reamer is suited for production and maintenance machining applications where a 0.2870-inch finished hole diameter is required. It fits within the 0.2500 to 0.2999 inch decimal inch reamer diameter range and is appropriate for use in drill presses, lathes, and milling machines. Machinists, tool-and-die technicians, and maintenance trades commonly reach for this size when finishing pin holes, bushing bores, and close-tolerance through-holes in ferrous and non-ferrous stock.

Key Features

• 0.2870-inch finished hole diameter with straight-cylindrical shank for secure chuck or collet seating
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• Six straight flutes for even chip load distribution and a consistent bore finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright, uncoated finish — no coating buildup to affect dimensional tolerance
• Not an over/under-size or dowel-pin reamer — standard decimal-inch sizing

Compatibility

Designed as a standard-fitment chucking reamer for machine tools accepting a straight-cylindrical shank in the 0.2500 to 0.2999 inch decimal inch diameter class, including drill presses, lathes, and milling machine setups.

Installation Notes

Chucking reamers are installed by licensed machinists or skilled maintenance trades using a standard drill chuck, collet, or toolholder rated for the shank diameter. Ensure the machine spindle is fully stopped and the workpiece is securely clamped before mounting or removing the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Inspect the reamer for edge chipping before each use — a damaged cutting edge will compromise hole diameter and surface finish.
