Magafor 88860004750 Chucking Reamer 0.1870 in Solid Carbide

Product Description

The MAGAFOR 88860004750 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a reamer diameter of 0.1870 inches and a tight diameter tolerance of 0.0002 inches, this tool delivers consistent, accurate bore sizing in production and job-shop environments. The 6-flute, left-hand spiral geometry with right-hand cutting action reduces chatter and promotes smooth chip evacuation. Overall length is 3.1500 inches with a flute length of 0.8270 inches. The bright, uncoated solid carbide construction handles hardened and abrasive workpiece materials where high-speed steel tooling falls short. Installed in a standard machine chuck, this reamer suits CNC machining centers, drill presses, and manual lathes.

The 88860004750 belongs to MAGAFOR Series 8600 and is sized for applications requiring finished holes in the 0.1500 to 0.1999 inch diameter range, equivalent to the 4.00 to 5.00 mm range, specifically at 4.75 mm. The straight-cylindrical shank allows direct chuck mounting without adapter sleeves, making it a practical choice for machinists, toolmakers, and precision-shop technicians working on close-tolerance bores in steel, cast iron, aluminum, and similar materials. Coolant-through capability is not included in this model.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive or hardened materials
• 0.1870 inch diameter with a 0.0002 inch tolerance for close-tolerance bore finishing
• 6-flute, left-hand spiral geometry with right-hand cutting direction reduces chatter and improves surface finish
• Bright, uncoated finish suitable for a wide range of metalworking materials
• Straight-cylindrical shank for direct chuck mounting on CNC and manual machine tools
• Part of MAGAFOR Series 8600, a standardized line of precision chucking reamers

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard chuck-mount machine tools requiring finished bore diameters of 0.1870 inches. Compatible with any machine spindle or chuck accepting a straight-cylindrical shank at this diameter range.

Installation Notes

Installation and operation should be performed by a qualified machinist or toolmaker familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer from the chuck. Confirm chuck runout is within acceptable limits before use, as excessive runout will compromise bore tolerance and tool life. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds when operating carbide reamers.
