Value Collection SM1500016 Chucking Reamer Letter E Cobalt

Product Description

The VALUE COLLECTION SM1500016 is a letter E chucking reamer designed to finish-ream holes to a precise 0.2500 inch diameter. Built from cobalt steel with a bright, uncoated finish, this reamer handles tough materials that would wear down standard high-speed steel tooling. It features 6 spiral flutes in a right-hand cutting direction, delivering smooth material removal and accurate sizing in a single pass. The straight-cylindrical shank seats securely in a drill chuck or collet holder on a drill press, lathe, or CNC machine. With a 6 inch overall length and a 1.5 inch flute length, this tool suits general-purpose production and maintenance reaming applications.

This chucking reamer is used in machine shops, maintenance facilities, and production environments where consistent hole sizing to 0.2500 inch is required. It is appropriate for reaming through ferrous and non-ferrous materials in both manual and CNC setups. The cobalt steel construction makes it a practical choice when cutting harder alloys or stainless steel that would degrade standard tooling more quickly. It is sold as a single unit and is intended for use by machinists and tool-and-die technicians.

Key Features

• Cobalt steel construction resists heat and wear when cutting hard or abrasive materials
• 6 spiral flutes in a right-hand cutting direction promote smooth chip evacuation and accurate sizing
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• 0.2500 inch finished diameter corresponds to Letter E sizing
• Bright, uncoated finish maintains sharp cutting edges out of the box
• 6 inch overall length with 1.5 inch flute length suits a wide range of workpiece thicknesses

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool spindle or drill chuck accepting a straight-cylindrical shank, suitable for producing finished holes at 0.2500 inch diameter across a range of materials and setups.

Installation Notes

Chucking reamers are installed and operated by machinists on drill presses, lathes, or CNC machining centers. Always secure the workpiece and power down the spindle before changing tooling. Use cutting fluid appropriate for the workpiece material to extend tool life and improve finish quality. Do not use a chucking reamer to remove excessive stock — pre-drill to within a few thousandths of the finished diameter before reaming.
