Magafor 88860003170 Chucking Reamer 1/8 in Solid Carbide

Product Description

The MAGAFOR 88860003170 is a solid carbide chucking reamer designed to finish-ream precision holes to a tight tolerance in machined components. Built to Series 8600 standards, this reamer features a 1/8 inch (0.1248 inch decimal) diameter with a tolerance of 0.0002 inches, making it suitable for applications where bore accuracy is critical. The 6-flute geometry with left-hand spiral and right-hand cutting direction improves chip evacuation and surface finish quality. The bright, uncoated carbide construction provides rigidity and wear resistance in a compact 2-1/4 inch overall length tool. Machinists and tool-and-die professionals typically install this reamer in CNC machining centers, drill presses, or manual lathes using a standard chuck or collet holder.

This chucking reamer is intended for finishing operations in ferrous and non-ferrous materials where a controlled, repeatable hole diameter is required. The straight-cylindrical shank allows direct mounting in standard collets and chucks without additional adapters. With a 0.5900 inch flute length, the tool is suited for shallow to moderate depth holes in precision machined parts, fixtures, and tooling plates. It is a single-piece solid carbide tool - no inserts, no brazed tips - which simplifies setup and reduces runout in tight-tolerance work.

Key Features

• Solid carbide construction for rigidity and long tool life in precision reaming applications
• 6-flute left-hand spiral design promotes smooth chip flow and improved bore finish
• Right-hand cutting direction compatible with standard spindle rotation
• Diameter tolerance of 0.0002 inches for tight, repeatable hole sizing
• Bright, uncoated finish - no coating variability affecting final hole diameter
• Straight-cylindrical shank fits standard collets and drill chucks without adapters

Compatibility

Designed as an OEM-style precision chucking reamer for use in CNC machining centers, drill presses, and manual lathes equipped with standard straight-shank collet systems or drill chucks accepting 1/8 inch shank tooling.

Installation Notes

A licensed machinist or tool-and-die technician should install this reamer in a properly trued collet or chuck to minimize runout before use. Always ensure the machine spindle is fully stopped and the tool is securely clamped before engaging the workpiece. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole finish quality. Do not use this reamer as a drill - it is a finishing tool intended for use after a pilot hole has been established at the correct pre-ream diameter.
