Grobet 31.216 Swiss-pattern File 8 in Cut 4 Narrow Pillar

Product Description

The GROBET 31.216 is a Swiss-pattern narrow pillar file designed for precision material removal in close-tolerance filing applications. At 8 inches overall length with a double-cut, Cut 4 tooth pattern, this file is built for fine, controlled work on hard metals, intricate shapes, and tight slots. The narrow pillar cross-section measures 9/32 inches wide by 9/64 inches thick, making it well-suited for filing narrow grooves, keyways, and confined profiles. It is fitted with a tang for use with a standard file handle. This tool is used by machinists, toolmakers, instrument technicians, and skilled tradespeople who require repeatable, fine-finish filing performance.

Swiss-pattern files are common in precision metalworking shops, toolrooms, and maintenance environments where fine surface finishing and dimensional accuracy matter. The Cut 4 rating indicates a very fine tooth pattern, appropriate for finishing passes on ferrous and non-ferrous metals, hardened steel components, and precision-fit parts. The narrow pillar shape allows access to slots, grooves, and recesses that standard flat or pillar files cannot reach. This file is sold individually and is intended for professional hand-filing operations.

Key Features

• Cut 4 double-cut Swiss-pattern tooth configuration for fine, controlled material removal
• Narrow pillar shape accesses tight slots, keyways, and confined profiles
• 8 inches overall length for balanced handling in bench and handheld work
• 9/32 inches wide by 9/64 inches thick cross-section for precision fitment in narrow recesses
• Tang end accepts standard file handles for secure grip during use
• Rectangular file shape maintains consistent geometry across the working surface

Compatibility

Designed as a Swiss-pattern precision hand file for use with any standard tang-type file handle; compatible with typical bench vise and hand-filing setups used in toolroom and maintenance machining applications.

Installation Notes

This file should always be fitted with an appropriate file handle before use to prevent tang injury. Secure the workpiece in a bench vise before filing. Apply consistent, controlled strokes and avoid rocking the file across the work surface to maintain flatness. Never use a file as a pry bar or striking tool, as the hardened steel is brittle and may fracture.
