Magafor 88860009490 Chucking Reamer 0.3736 in Solid Carbide

Product Description

The MAGAFOR 88860009490 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a reamer diameter of 0.3736 inches (9.49 mm) and a diameter tolerance of 0.0000 to +0.0005 mm, this tool delivers tight, consistent sizing in finish-reamed bores. The straight shank allows direct mounting in standard drill chucks or collet holders. Six flutes with a left-hand spiral geometry and right-hand cutting direction promote smooth chip evacuation and reduce chatter during the cut. A bright polished finish minimizes friction and helps extend tool life. Machinists and toolroom technicians working in job shops, production environments, or maintenance applications will find this reamer suited to demanding close-tolerance work.

This reamer is intended for finish reaming operations where bore diameter accuracy and surface finish are critical. It is well suited for use in CNC machining centers, knee mills, and drill presses where a straight-shank tool can be held securely in a collet or drill chuck. The 0.3736-inch diameter falls in the 0.3500 to 0.3999-inch range, making it appropriate for applications requiring near-10 mm bore finishing. Typical materials reamed include steel, aluminum, brass, and cast iron where solid carbide tooling is preferred over high-speed steel for harder workpieces or higher production rates.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• 0.3736-inch (9.49 mm) diameter with a tolerance of 0.0000 to +0.0005 mm for precise bore sizing
• Six-flute left-hand spiral geometry with right-hand cutting direction for smooth chip flow
• Bright polished finish reduces friction and aids chip evacuation
• Straight shank compatible with standard drill chucks and collet holders
• Overall length of 4-31/32 inches with a flute length of 1-27/64 inches for reach and cutting depth control

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for straight-shank toolholders and collet systems accepting a 0.3736-inch diameter shank in standard machining setups.

Installation Notes

Chucking reamers should be installed by a qualified machinist following standard toolroom practices. Ensure the machine spindle is fully stopped and the tool is securely seated in the collet or chuck before beginning any cut. Use appropriate cutting fluid for the workpiece material to maintain tool life and surface finish quality. Do not use this reamer to remove excessive stock - rough drill the bore to within a few thousandths of final diameter before reaming.
