Norton 614636-86115 Square Abrasive File Stone MF46

Product Description

The NORTON 614636-86115 is a square-profile India abrasive file stone designed for precision hand-filing and deburring tasks in maintenance, toolroom, and fabrication settings. India stones are aluminum oxide abrasive bonded in a hard matrix, offering consistent stock removal on ferrous metals, tool steel, and hardened surfaces. This stone measures 6 inches in length by 0.5 inches square cross-section and is graded at MF46 grit, a medium-coarse grit suited for initial shaping and moderate material removal. Machinists, tool-and-die technicians, millwrights, and skilled tradespeople reach for this format when a bench grinder is too aggressive and a flat stone is the right call.

This square file stone is used in toolroom and maintenance applications where precise, controlled hand-filing is required on slots, keyways, dies, molds, and similar confined or flat surfaces. The square profile allows work on internal corners and narrow slots that flat or round profiles cannot reach. Typical users include machinists, maintenance mechanics, and precision grinding technicians working in both light industrial and heavy manufacturing environments.

Key Features

• India aluminum oxide construction for consistent, controlled abrasion on ferrous and hardened materials
• MF46 medium-coarse grit rating for effective initial shaping and stock removal
• Square cross-section profile accesses internal corners, slots, keyways, and confined surfaces
• 6-inch length provides adequate stroke length for most bench filing tasks
• Hard bond matrix maintains shape and resists loading during extended use

Compatibility

Designed as a general-purpose hand file stone for use with oil or dry on ferrous metals, tool steels, and hardened surfaces in toolroom, maintenance, and fabrication applications.

Installation Notes

File stones of this type are used by hand without power tools. Secure the workpiece in a vise or fixture before filing to maintain control and prevent injury. Apply a light honing oil or cutting fluid to extend stone life and float away swarf during use. Inspect the stone for chips or cracks before each use and store flat to prevent warping or breakage.
