Magafor 88867010200 Carbide Chucking Reamer 0.4016 in Spiral H7

Product Description

The MAGAFOR 88867010200 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. Built to DIN 8089-C standards, it produces H7-tolerance bores suited for close-fit assemblies and press-fit applications. The reamer measures 0.4016 inches in diameter with an overall length of 2.8 inches and a flute length of 0.9840 inches. Spiral flutes in a right-hand cutting direction promote smooth chip evacuation and consistent surface finish. Coolant-through capability supports both wet and minimum-quantity-lubrication setups, extending tool life in production environments. This tool is sized for machinists and tool-and-die professionals running CNC lathes, machining centers, or manual drill presses.

This reamer is intended for finishing pre-drilled or bored holes to H7 tolerance in ferrous and non-ferrous workpieces. The straight cylindrical shank seats directly in a collet chuck or keyless drill chuck without additional adaptation. The DIN 8089-C designation and blind-hole suitability make it a practical choice for close-tolerance work in job shops, production floors, and maintenance machining environments where repeatable bore sizing is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• H7 reamer diameter tolerance for precision close-fit and interference-fit bore applications
• Spiral flute geometry promotes chip flow and reduces chatter in through and blind holes
• Coolant-through design supports high-speed production runs and extended tool life
• Straight cylindrical shank for direct collet or drill chuck mounting
• Rated for blind hole use per DIN 8089-C specification

Compatibility

Designed as an OEM-style machine reamer for use in CNC machining centers, CNC lathes, and manual drilling equipment accepting a straight cylindrical shank. Suitable for finishing holes in the 0.4000 to 0.4999 inch diameter range to H7 tolerance.

Installation Notes

This reamer is installed and operated by machinists or tool-and-die technicians following standard machine tool setup procedures. Ensure the machine spindle is fully stopped and the tool is secured firmly in a collet or drill chuck before starting the cut. Always verify pre-drill diameter is within the recommended stock allowance for the target H7 bore before reaming. Follow shop floor coolant and speeds-and-feeds guidelines appropriate to the workpiece material and machine rigidity.
