Magafor 88860001550 Chucking Reamer 0.061in Solid Carbide

Product Description

The MAGAFOR 88860001550 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. With a diameter of 0.061 inches (1.55 mm) and a diameter tolerance of 0.0000 to +0.0003 mm, this reamer delivers the dimensional accuracy required in toolroom, production, and instrument-grade work. The four-flute, left-hand spiral geometry with right-hand cutting direction helps evacuate chips efficiently while maintaining hole geometry. A bright polished finish reduces friction and extends tool life in non-ferrous and ferrous materials. This reamer is intended for use in CNC machining centers, manual mills, and drill presses by machinists and toolmakers.

This reamer is suited for finishing pre-drilled or bored holes to precise diameter in small-bore applications. The straight shank allows direct clamping in collet chucks, drill chucks, or ER-style toolholders. Its compact overall length of 1-9/16 inches and 25/64 inch flute length make it appropriate for shallow-hole reaming in close-quarters setups. Typical applications include precision instrument components, hydraulic valve bodies, and tooling fixtures where sub-0.1 inch bore accuracy is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision boring
• 0.061 inch diameter with tolerance held to 0.0000 to +0.0003 mm
• Four-flute left-hand spiral with right-hand cutting for controlled chip flow
• Bright polished finish minimizes built-up edge and reduces cutting friction
• Straight shank for use in standard collet and drill chuck toolholders
• Compact 1-9/16 inch OAL suited for shallow-hole and confined-space reaming

Compatibility

Designed as an OEM-style replacement or direct tooling selection for small-bore chucking reamer applications requiring a 0.061 inch diameter straight-shank carbide reamer.

Installation Notes

Installation and use should be performed by qualified machinists familiar with precision reaming practices. Secure the straight shank in a properly sized collet or drill chuck before operation, and verify runout is within acceptable limits before engaging the workpiece. Always bring the spindle to the correct RPM and feed rate for the workpiece material before entry, and use appropriate cutting fluid to maintain finish quality and tool life. Do not use this reamer to remove excessive stock - pre-drill or bore to within a few thousandths of final diameter before reaming.
