Grobet 31.633 Swiss-pattern Needle File Three Square Cut 0

Product Description

The GROBET 31.633 is a Swiss-pattern needle file with a three-square (triangular) profile and a Cut 0 coarseness rating. Designed for precision material removal in tight or angled workspaces, this file measures 5.5 inches overall length with a 2.5-inch length of cut. The tang-style end accepts a standard file handle, sold separately. It is commonly used by machinists, pipefitters, electricians, and tool-and-die technicians who require controlled filing in corners, slots, and small triangular profiles. The Swiss-pattern grind delivers consistent tooth geometry suited for ferrous and non-ferrous metals.

This file is appropriate for bench work and field use wherever fine-to-medium stock removal is needed on metal parts, fasteners, keyways, or internal angles. The three-square shape makes it well suited for deburring threaded components, opening slots, and sharpening saw teeth. At 5.5 inches OAL, it fits comfortably in one hand for controlled strokes. Tradespeople working in HVAC, plumbing, and electrical installations use files like this for fitting conduit knockouts, burring copper fittings, and dressing metal edges before assembly.

Installation Notes

A licensed mechanic, machinist, or qualified tradesperson should select the appropriate Cut rating and file profile for the material being worked. Always attach a properly fitted handle to the tang before use to prevent hand injury. Secure the workpiece in a vise or clamp before filing to maintain control and avoid slipping. Inspect the file for cracks or damaged teeth before each use and replace if compromised.
