Precision Twist Drill 5010717 Hss Chucking Reamer 7/8 in

Product Description

The PRECISION TWIST DRILL 5010717 is a high-speed steel chucking reamer with a straight flute design, built for precision hole finishing in metalworking applications. At 7/8 inch diameter and 10 inches in overall length, this reamer is sized for jobs that demand tight tolerances and clean bore surfaces. High-speed steel construction provides the hardness and heat resistance needed for reaming operations in steel, cast iron, aluminum, and similar materials. It is installed via a standard chuck on a drill press, lathe, or similar machine tool by machinists and maintenance trades.

This chucking reamer is suited for machine-driven reaming in both production and maintenance settings. The straight flute geometry is appropriate for through-holes and short blind holes where chip clearance is manageable. Typical applications include finishing drilled holes to precise diameters in ferrous and non-ferrous metals. It is commonly used in industrial maintenance, fabrication shops, and machine shops where OEM-style hole tolerances must be held.

Key Features

• High-speed steel (HSS) construction for hardness and heat resistance during machine reaming
• Straight flute design suited for through-holes and general-purpose reaming operations
• 7/8 inch cutting diameter for finishing holes to close tolerances
• 10 inch overall length provides reach for deeper setups or extended-reach toolholders
• Chucking-style shank for use in drill presses, lathes, and milling machines

Compatibility

Designed for use in standard drill press, lathe, or milling machine chucks compatible with a 7/8 inch chucking reamer shank. Consult machine specifications to confirm chuck capacity before installation.

Installation Notes

This reamer is installed and operated by machinists or qualified maintenance personnel using a drill press, lathe, or milling machine. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Ensure the workpiece is securely fixtured and the reamer is running true before engaging the cut.
