Magafor 88860000730 Chucking Reamer 0.0287 in Solid Carbide

Product Description

The MAGAFOR 88860000730 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. With a cutting diameter of 0.0287 inches (0.73 mm) and a 4-flute spiral configuration, this reamer produces clean, accurate bores in hard and abrasive materials where high-speed steel tooling falls short. The bright polished finish reduces friction and aids chip evacuation. At 1.3125 inches overall length with a 9/32-inch flute length and straight shank, it is sized for small-bore work in CNC machining centers, drill presses, and manual lathes. Machinists and tool-and-die professionals will find this reamer well suited to high-accuracy finish reaming of miniature bores.

This reamer is intended for precision finish reaming of small-diameter holes in metalworking environments. The micro-diameter range makes it appropriate for instrument components, medical device machining, mold and die work, and other applications requiring bore accuracy at the sub-0.030-inch range. The right-hand cutting direction combined with left-hand spiral flutes helps pull chips away from the cutting zone, keeping the bore clean during the pass. It is suited for use in ferrous and non-ferrous metals as well as some engineered plastics where solid carbide tooling is the appropriate choice.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• 4-flute left-hand spiral geometry with right-hand cutting direction for controlled chip evacuation
• Bright polished finish reduces friction and buildup on cutting edges
• Diameter tolerance of 0.0000 to +0.0003 mm for tight-tolerance bore finishing
• Straight shank fits standard collet chucks and drill chuck configurations
• Compact overall length of 1.3125 inches suits short-reach and confined-space setups

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard straight-shank collet chucks and drill chucks accepting tools in the micro-diameter range.

Installation Notes

Chucking reamers in this diameter class are typically installed and operated by machinists using a CNC machining center, drill press, or lathe with appropriate collet or drill chuck. Power down and de-energize the machine spindle before changing tooling. Use the correct cutting fluid or coolant recommended for the workpiece material, as dry reaming at this diameter can cause premature edge wear. Do not use this reamer to remove excessive stock - pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
