Precision Twist Drill 5010661 Hss Chucking Reamer 3/8 in

Product Description

The PRECISION TWIST DRILL 5010661 is a high-speed steel (HSS) chucking reamer with a straight flute design, built for precision hole finishing in metal fabrication and mechanical assembly work. With a 3/8-inch tip diameter and an overall length of 7 inches, this reamer is sized for common bore finishing tasks where tight tolerances and smooth surface finish are required. HSS construction provides the hardness and wear resistance needed for reaming ferrous and non-ferrous materials. Machinists and trade professionals use chucking reamers in drill presses, lathes, and milling machines to bring drilled holes to final dimension.

This reamer is suited for shop and field applications where holes must be finished to close dimensional tolerance after drilling. The straight flute geometry makes it appropriate for through-holes and is well-suited for use with cutting fluid to extend tool life and improve finish quality. At 0.1 pounds, it is lightweight and easy to handle in a standard chuck setup. It is sold individually.

Key Features

• High-speed steel (HSS) construction for durability in ferrous and non-ferrous materials
• Straight flute design suited for through-hole finishing applications
• 3/8-inch tip diameter for common bore finishing work
• 7-inch overall length for reach in standard chuck setups
• Lightweight at 0.1 pounds for easy handling

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill press, lathe, or milling machine chucks accepting 3/8-inch shank tooling.

Installation Notes

Chucking reamers are installed and operated by machinists using drill presses, lathes, or milling machines. Always secure the reamer firmly in the chuck before operation and verify spindle speed is appropriate for the material being reamed. Use a suitable cutting fluid to reduce heat buildup and extend tool life. Never force a reamer through an undersized hole — ensure the pre-drilled hole is within the recommended allowance for the reamer diameter.
