Precision Twist Drill 5010350 Hss Chucking Reamer 1/8 in

Product Description

The PRECISION TWIST DRILL 5010350 is a high-speed steel (HSS) chucking reamer with a straight flute design, built for precision finishing of drilled holes to tight tolerances. At 1/8 inch diameter and 3.5 inches in overall length, this reamer is suited for enlarging and finishing small-bore holes in metal workpieces. HSS construction provides the hardness and heat resistance needed for consistent performance across a range of ferrous and non-ferrous materials. Machinists and tooling technicians reach for this style of reamer when a drilled hole needs to be brought to a precise final diameter with a clean, smooth finish.

This chucking reamer is intended for use in machine operations such as drill press, lathe, or CNC setups where the tool is held in a chuck and driven at controlled speed and feed rates. The straight flute geometry makes it well suited for through-hole reaming in softer metals and general-purpose shop work. It is sold individually and is appropriate for production environments, maintenance shops, and job shops that require small-diameter reaming capability.

Key Features

• High-speed steel construction for hardness and heat resistance during machine reaming
• Straight flute design suited for through-hole reaming in a variety of metals
• 1/8 inch diameter for small-bore precision finishing applications
• 3.5 inch overall length compatible with standard chuck setups
• Sold individually, no minimum quantity beyond one unit

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill press, lathe, or CNC chuck applications requiring a 1/8 inch straight-flute HSS reamer.

Installation Notes

Chucking reamers are installed by machinists or tooling technicians using a standard drill chuck or collet on a drill press, lathe, or machining center. Always secure the workpiece firmly before reaming and ensure the machine is powered down and locked out before changing tooling. Use appropriate cutting fluid for the material being reamed to extend tool life and improve finish quality. Do not use a chucking reamer as a hand tool — it is designed for machine use only.
