Precision Twist Drill 5010693 Hss Chucking Reamer 9/16 in

Product Description

The PRECISION TWIST DRILL 5010693 is a high-speed steel (HSS) chucking reamer with a straight flute design, built for precision hole finishing in metal fabrication and machining applications. With a 9/16 inch diameter tip and an overall length of 8 inches, this reamer is sized for standard chucks on drill presses, lathes, and hand-held power tools. HSS construction provides the hardness and heat resistance needed to hold tight tolerances through repeated use on ferrous and non-ferrous materials. Machinists, pipefitters, and mechanical contractors reach for chucking reamers when a drilled hole needs to be brought to a precise final diameter with a smooth, clean finish.

This reamer suits metal shop work, mechanical contracting, and field machining scenarios where hole diameter accuracy is critical. Typical applications include sizing holes in pipe flanges, mechanical assemblies, and structural components prior to fastener or pin installation. The 8 inch length provides reach for deeper workpieces while remaining manageable in standard chucks. The straight flute geometry makes it well suited for through-hole reaming in most common shop materials.

Key Features

• High-speed steel construction for hardness and heat resistance during metal reaming
• Straight flute design for through-hole applications in ferrous and non-ferrous materials
• 9/16 inch diameter tip for precision final hole sizing
• 8 inch overall length for reach into deeper workpieces
• Chucking-style shank compatible with standard drill press and lathe chucks

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer compatible with standard drill press, lathe, and power tool chucks accepting a chucking-style shank at 9/16 inch diameter.

Installation Notes

Chucking reamers are installed and operated by machinists and mechanical trade professionals using drill presses, lathes, or similar powered equipment. Secure the shank firmly in the chuck before operation and ensure the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid for the material being reamed to extend tool life and improve finish quality. Never exceed the recommended feed rate for the material, as forcing a reamer can cause chatter, oversize the hole, or damage the flutes.
