Precision Twist Drill 5010480 Hss Chucking Reamer 3/16 in

Product Description

The PRECISION TWIST DRILL 5010480 is a high-speed steel (HSS) chucking reamer with a straight flute design, built for precision hole finishing in metal, plastic, and composite materials. With a 3/16-inch tip diameter and an overall length of 4.5 inches, this reamer is sized for tight-tolerance applications where a drilled hole must be brought to a precise final diameter. HSS construction provides the hardness and heat resistance needed for general-purpose reaming on manual drill presses, lathes, and CNC equipment. Machinists and trade professionals use this tool when drilled holes require a smooth, accurate finish before assembly or fitting.

This chucking reamer is suited for use in machine tool applications where the reamer is held in a chuck or collet and driven by a powered spindle. It is appropriate for light-to-medium material removal during hole finishing operations in maintenance, fabrication, and repair environments. The straight flute design performs reliably in through-holes and blind holes alike, making it a practical choice for shops handling a variety of materials and tolerances.

Key Features

• High-speed steel construction delivers hardness and heat resistance for machine reaming operations
• Straight flute geometry provides consistent chip evacuation in through-hole and blind-hole applications
• 3/16-inch tip diameter for precision hole sizing to close tolerances
• 4.5-inch overall length accommodates standard chuck depths on drill presses and lathes
• Chucking-style shank for secure, concentric hold in powered spindle equipment

Compatibility

Designed as an OEM-style replacement or standard shop reamer compatible with any drill press, lathe, or CNC spindle capable of accepting a chucking-style shank at 3/16-inch diameter.

Installation Notes

This reamer is installed and operated by machinists and qualified trade professionals using powered drill presses, lathes, or CNC equipment. Secure the shank fully in the chuck or collet before operation and verify runout before cutting. Always use an appropriate cutting fluid for the material being reamed to extend tool life and improve surface finish. Never use a chucking reamer as a hand-turn tool, as uneven torque can damage flutes or cause undersized holes.
