Value Collection 551SF Chucking Reamer Set 29 Piece Hss

Product Description

The VALUE COLLECTION 551SF is a 29-piece chucking reamer set covering a full fractional inch range from 1/16 inch through 1/2 inch. Each reamer is ground from high-speed steel and features a spiral flute geometry with right-hand cut and right-hand spiral direction, producing a clean, accurate bore finish in a wide range of materials. Straight shanks allow direct chucking in drill presses, lathes, and CNC machining centers. The set stores in a metal case that keeps each reamer organized and protected between uses. Machinists, tool-and-die workers, and maintenance technicians reach for this set when they need a ready supply of sized reamers without pulling individual pieces from stock.

This set suits general-purpose reaming applications in job shops, maintenance departments, and production environments. It is appropriate for use in ferrous and non-ferrous metals, plastics, and composite materials where a precise, finished hole diameter is required after drilling. The 29 fractional sizes in 64th-inch increments between 1/16 inch and 1/2 inch cover the most commonly called-out hole sizes in mechanical assembly, fixture building, and equipment repair work. The metal storage case makes the set practical for both bench use and tool-crib issue.

Key Features

• 29 fractional sizes from 1/16 inch to 1/2 inch in 64th-inch increments
• High-speed steel construction for durability across a broad range of workpiece materials
• Spiral flute design helps evacuate chips and reduces chatter during the cut
• Right-hand cut and right-hand spiral direction compatible with standard machine spindle rotation
• Straight shank fits standard drill press, lathe, and machining center chucks
• Metal storage case keeps all 29 pieces indexed and protected

Compatibility

Designed as a general-purpose fractional chucking reamer set for use in any machine tool equipped with a standard chuck that accepts straight-shank tooling.

Installation Notes

Chucking reamers are installed and removed by a qualified machinist or toolroom technician with the machine spindle fully stopped and locked out per applicable safety procedures. Ensure the shank is fully seated and the chuck is tightened before starting the spindle. Reamers are finish tools and should follow a drilled or bored hole that is already close to final size; removing excessive stock in a single reaming pass can shorten tool life and degrade hole finish. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish quality.
